A–Z

Every term, one sentence each.

Definitions are written to be lifted: one sentence, no hedging, no marketing. Follow any term for where it comes up across the library.

A

A+ ContentAmazon-specific: Amazon's enhanced brand content module on a listing, which increasingly needs to carry structured, factual detail because Alexa for Shopping draws on it when answering shopper questions.
A+ PremiumAmazon-specific: Amazon's higher content tier for eligible brands, adding interactive modules — comparison hotspots, video-led layouts, expanded comparison grids — and a larger module budget on top of the standard A+ library. Eligibility and exact module names vary by program and account type; the constant is more format, gated by qualification.
ACOSAmazon-specific: Advertising cost of sale — ad spend divided by ad-attributed revenue only — the older metric that understates efficiency once Alexa for Shopping and off-site assistants drive organic-looking sales.
Agent-attributed revenuePlatform & products: Order value that can be traced to an agent conversation — either directly, because the checkout was initiated inside the conversation, or as an assist, because the shopper had a substantive agent conversation within a defined window before purchasing through the normal storefront.
Agent-collected contextShopify: Structured facts a shopper reveals during a Brand Agent conversation - stated preferences, product questions, unresolved needs - extracted and stored as tagged profile fields rather than kept as raw conversation transcript.
Agent-influenced arrivalGrowth & retention: A new subscriber whose path to signup included an AI assistant's recommendation, comparison, or summary - on-site (a Brand Agent conversation) or off-site (ChatGPT, Claude, Perplexity, Gemini, Google AI Overviews, or Amazon's Alexa for Shopping). Distinct from organic browsing, where the shopper found and evaluated the brand unassisted.
Agentic checkoutPlatform & products: A checkout initiated or completed by an AI agent for a shopper, either inside the AI surface the shopper is using or on the merchant's site, using payment credentials the shopper has authorized. The merchant remains the seller and merchant of record; the agent handles the steps a person would otherwise click through.
Agentic commercePlatform & products: Commerce transactions initiated, researched, or completed with an AI agent acting on the shopper's behalf, rather than a human clicking through a storefront unassisted.
Agentic commerce leadAgency & delivery: The person who owns the outcome of AI-facing commerce surfaces — Brand Agent behavior, catalog machine-readability, checkout configuration, and off-site AI visibility — across catalog data, conversation design, platform configuration, and measurement. Distinct from a developer who implements a single piece of it.
Agentic Commerce ProtocolPlatform & products: An open standard, licensed under Apache 2.0, for how AI agents, buyers and businesses complete purchases through APIs. Released by OpenAI and Stripe on September 29, 2025; Meta joined as a lead maintainer on April 24, 2026. It defines agentic checkout, cart and product feeds, delegated payment, delegated authentication, and order webhooks. The spec is labeled beta.
Agentic Commerce Readiness ScoreMeasurement & delivery: GigaCommerce's free 100-point, three-minute assessment that grades a merchant's catalog, structured data, and checkout readiness for Brand Agents and AI search.
Agentic Commerce SetupPlatform & products: GigaCommerce's flagship engagement: a fixed-scope implementation that gets a merchant's Brand Agent, catalog data, and checkout configuration live within two weeks.
Agentic Commerce SuitePlatform & products: Stripe's product for selling through AI agents, launched December 11, 2025. A seller shares a catalog feed with Stripe; Stripe syndicates products to connected agents, manages the checkout, processes the payment and sends the seller an order event. Each stage can be taken over by the seller. Stripe describes it as working across protocols, including ACP and Google's UCP.
Agentic e-commercePlatform & products: Online selling in which AI agents, rather than people, carry out some of the shopping steps: searching catalogs, comparing products against a shopper's constraints, and in some channels completing checkout after the shopper confirms. Also called agentic commerce or agentic AI e-commerce.
Agentic planPlatform & products: A Shopify plan for businesses not using Shopify as their storefront, letting them sync products to Shopify Catalog and sell in AI channels; announced in Shopify's Spring '26 Edition (check Shopify for current availability and pricing).
Agentic storefrontGEO & AI search: Shopify's name for a store's presence inside an AI channel such as ChatGPT, Microsoft Copilot, Google AI Mode and Gemini, or Meta. Products reach those channels through Shopify Catalog, and the merchant controls per-channel settings such as direct checkout from the Shopify admin.
Agentic storefrontsPlatform & products: Shopify's way of selling inside AI channels such as ChatGPT, Microsoft Copilot and Google AI Mode — active by default for eligible stores and managed under Sales channels → Agentic.
AI Assistant channelGEO & AI search: A channel in GA4's default channel group for visits from AI assistants such as ChatGPT, Gemini, Deepseek, Copilot and Grok. Its rule is that the medium exactly matches ai-assistant. GA4 sets that medium, and the campaign (ai-assistant), when the referrer matches Google's list of AI assistants. Google says the channel excludes its own AI Overviews and AI Mode.
AI citation auditGEO & AI search: A structured test of how AI assistants treat your brand when shoppers ask buying questions in your category. You run a fixed panel of questions across the major assistants and score each answer on a three-level scale - named in the recommendation, cited as a source, or absent - producing a score you can track and a gap log you can act on.
AI Citation CheckGEO & AI search: GigaCommerce's free tool that tests whether AI assistants currently cite or recommend a given merchant's products for its own core queries.
AI crawlerGEO & AI search: A bot operated by an AI company (OpenAI, Anthropic, Google, Perplexity, and others) that fetches web content specifically to train models or answer live user queries.
AI impression shareGEO & AI search: Our working metric: a page's impressions in Search Console's Generative AI performance report divided by its impressions in the Performance report (Web search type), for the same dates, country and device filters. It shows how much of a page's Google visibility came through AI Overviews and AI Mode. It is not a click or traffic share.
AI ModeGEO & AI search: Google Search's conversational mode, launched in the U.S. on May 20, 2025. Google describes it as using a "query fan-out" technique that breaks a question into subtopics and searches each one. In Search Console, a follow-up question in AI Mode counts as a new query.
AI OverviewsGEO & AI search: The AI-generated summary Google shows at the top of some regular search results pages, with links to the sources it draws on. Search Console treats an AI Overview as a single position on the results page: every link inside it gets that same position.
AI shopping channelPlatform & products: An AI assistant or AI search surface that recommends products to shoppers and links to, or completes, the purchase. The main ones in 2026 are ChatGPT, Microsoft Copilot, Google AI Mode and the Gemini app, and Perplexity. Each one reads product data from a catalog, a feed or the open web, and each has its own rules for checkout.
AI traffic attributionGEO & AI search: The practice of identifying visits and orders that started with an AI assistant or AI search feature, such as ChatGPT, Gemini, Copilot, Perplexity, Google AI Overviews or AI Mode, and assigning them revenue credit under a stated attribution model. It covers both the classification (which sessions count as AI) and the credit rule (how much of an order the AI touch earns).
AI-attributed revenueGEO & AI search: Purchase revenue from sessions whose source GA4 can identify as an AI assistant, using last-click attribution within the session. It excludes purchases influenced by AI answers that arrived through Organic Search, Direct or another channel, so it understates AI's total effect.
AI-referred trafficGEO & AI search: Website sessions that arrive by a click from an AI assistant such as ChatGPT, Perplexity, Gemini or Copilot, identified by the referrer the assistant passes. It excludes Google's AI Overviews and AI Mode, which GA4 counts as Organic Search, and it misses AI visits whose referrer was stripped, which land in Direct.
Alexa for ShoppingPlatform & products: Amazon's built-in AI shopping assistant, renamed from Rufus on May 13, 2026, which answers product questions directly inside the Amazon app and site using Amazon's own catalog and review data.
Amazon Marketing CloudAmazon-specific: Amazon's clean-room analytics workspace, built on AWS Clean Rooms, where advertisers analyze pseudonymized ad and conversion events and get back only aggregated, anonymous results.
Answer-first structureGEO & AI search: Writing the conclusion or direct answer as the first sentence of a section, with supporting reasoning and caveats following it — the inverse of narrative or journalistic structure, which builds to a conclusion.
Attribute coverageCatalog & data: The percentage of SKUs in a category that have a given structured field populated — the core metric for measuring how enriched a catalog actually is.
Attribution modelGEO & AI search: The rule an analytics tool uses to divide credit for a conversion among the touchpoints that preceded it. Last-click models give all credit to the final qualifying visit. Data-driven models spread credit based on how each touchpoint changed the observed likelihood of converting.

B

Backend attributeCatalog & data: Amazon search terms and fields that aren't shown on the listing but still feed indexing and, increasingly, Alexa for Shopping's ability to answer questions about the product.
Brand AgentPlatform & products: Microsoft's AI shopping agent for a merchant's own storefront, announced in January 2026 and installed through Microsoft Clarity plus Microsoft's waitlist — not a Shopify feature, and not limited to Shopify Plus. Brand Agents was in beta as of Microsoft's July 2026 documentation, for Shopify and WooCommerce sites.
bridgeCross-border & sourcing: Our name for the move from contract manufacturing (making products for someone else's brand at a wholesale price) to selling your own brand directly to US marketplace shoppers. It has four sequential spans: entity and compliance, brand, listing and catalog, and operations.
Browse nodeAmazon-specific: A single category or sub-category position in Amazon's browse tree — the hierarchical structure shoppers navigate through department and category pages. Each ASIN is assigned to one or more browse nodes, which determines where it surfaces when a shopper browses (as opposed to searches) and which category-level filters and comparison sets apply to it.
Browse treeAmazon-specific: Amazon's internal category hierarchy that a listing is filed under, which determines what filters and comparisons a listing is eligible to appear in.
Buying-question panelGEO & AI search: A fixed, versioned list of 15-30 questions phrased the way real shoppers ask them, mostly without your brand name in the question. Locking the wording is what makes results comparable between audit runs.

C

Catalog debtCatalog & data: The accumulated backlog of missing, inconsistent, or prose-trapped product data that silently degrades agent accuracy and AI search visibility over time.
Catalog enrichmentCatalog & data: The process of extracting facts trapped in product-description prose and turning them into structured fields an agent can query directly.
Category attribute templateCatalog & data: A fixed, reusable list of the attribute fields every SKU in a given category must carry — e.g. every hiking boot gets material, closure, waterproof rating, sole type, weight — built once per category and then applied to every SKU in it.
Category metafieldCatalog & data: A Shopify metafield tied to a category in the Standard Product Taxonomy (where it's called a product attribute), such as size, color or material, with predefined values that can be linked to variant options and reused across products.
ChatGPT AdsPlatform & products: OpenAI's advertising program for ChatGPT. Ads are paid placements, clearly labelled and shown separately from ChatGPT's response, to eligible users on the Free and Go plans. Advertisers buy them through OpenAI Ads Manager Beta, partners, or OpenAI's sales team, and pay per impression or per valid click.
ChatGPT referral trafficGEO & AI search: Visits to your online store that arrive from a link in ChatGPT, whether the link came from Shopify's agentic storefronts (product listings fed by Shopify Catalog) or from ChatGPT's search answers. Both reach your store as ordinary online store sessions, identified by their referrer when the browser passes one.
Checkout extensibilityShopify: Shopify's framework for customizing checkout using UI extensions and checkout functions instead of editing checkout.liquid directly. It lets merchants add or modify specific, sanctioned surfaces of checkout — banners, fields, upsells, delivery options — while Shopify continues to own and update the core checkout flow underneath.
Children's Product CertificateCross-border & sourcing: The certificate a manufacturer or importer must issue for any product designed primarily for children 12 and under, based on passing tests performed by a CPSC-accepted third-party laboratory. General-use products subject to a CPSC rule need the self-issued equivalent, a General Certificate of Conformity (GCC).
CitationGEO & AI search: An instance of an AI assistant referencing or recommending a specific merchant, product, or piece of content in its response to a user query.
Citation rateGEO & AI search: The share of relevant queries in which a given assistant cites or recommends a merchant's products — the core benchmark metric for Commerce GEO work.
Commerce GEOGEO & AI search: Generative engine optimization applied to commerce — the practice of structuring a catalog and content so AI assistants like ChatGPT, Claude, Gemini, and Perplexity cite and recommend it.
Commercial invoiceCross-border & sourcing: The document that states what was sold, to whom, at what price, and under what terms — the primary document US Customs and Border Protection uses to value the shipment and assess duty. It must match the packing list and the actual goods exactly.
Compatibility dataCatalog & data: Structured "works with" or "fits" relationships between products, which agents rely on heavily because shoppers frequently ask compatibility questions by exact model or part.
Confidence thresholdPlatform & products: The internal setting that decides whether a Brand Agent answers directly or escalates to a human. Set too low, it guesses too often; set too high, it escalates so much the feature stops saving anyone time.
Constraint queryCatalog & data: A shopping request framed by conditions the answer must satisfy — a device it must fit, a system it must work with, a situation it must handle — rather than by a product category alone.
Context hintsPlatform & products: Short descriptions an advertiser adds at the ad-group level to describe the conversations, topics or keywords where its products may be relevant. OpenAI says they guide matching but are not exact-match keywords and don't guarantee delivery in any specific conversation.
Controlled vocabularyCatalog & data: A fixed, finite list of allowed values for an attribute — e.g. material: cotton | linen | wool | leather — maintained centrally, so every SKU spells the same fact the same way.
Conversation designPlatform & products: The deliberate scripting of how a Brand Agent greets, questions, and guides a shopper — tone, fallback behavior, and escalation paths, not just the product answers underneath.
Conversation flowPlatform & products: A named pattern of shopper intent — e.g. 'compare two products on a specific attribute' — paired with the reasoning logic and catalog data the Brand Agent needs to answer any phrasing of that intent well, not a single scripted exchange.
Conversion rateGEO & AI search: The share of sessions that end in a purchase or another key event. GA4 calls the session version Session key event rate: "the percentage of sessions that converted". Revenue per session (or per visit) divides purchase revenue by sessions and captures order value as well as conversion.
Conversion spreadCross-border & sourcing: The difference between the true mid-market exchange rate at the moment of conversion and the (worse) rate a bank or payment provider actually applies to the transaction. It is usually not itemized as a fee, which is exactly why it is the most commonly missed cost in a payout comparison.
Conversions APIGEO & AI search: OpenAI's server-to-server endpoint for ChatGPT Ads conversion events. Your backend posts confirmed events, such as a paid order, with a Pixel ID and a separate Conversions API key. OpenAI calls it a more reliable tracking source than the Pixel alone.
Copilot CheckoutPlatform & products: Microsoft's checkout inside Microsoft Copilot, announced in January 2026 — a Microsoft product, not a Shopify one; for Shopify merchants it runs on Shopify's direct checkout, and the order books into the merchant's store like any other.
Core Web VitalsShopify: Google's three page-experience metrics. A good score is Largest Contentful Paint within 2.5 seconds, Interaction to Next Paint of 200 milliseconds or less, and Cumulative Layout Shift of 0.1 or less, measured at the 75th percentile of page loads, separately for mobile and desktop.
CorroborationGEO & AI search: Independent confirmation of a claim from a source that isn't the brand itself. In GEO terms, it's the difference between a fact an assistant can state with confidence and one it has to hedge or omit.
Corroboration graphGEO & AI search: The network of independent mentions, reviews, and citations of a product across the web that AI assistants use as a trust signal before recommending it.
Corroboration layerAmazon-specific: The body of buyer-generated content — reviews and answered Q&A — that an AI assistant uses to verify, qualify, or contradict the claims a seller makes in listing copy. Strong corroboration produces confident recommendations; weak or contradicting corroboration produces hedged answers or exclusion.
Custom channel groupGEO & AI search: A copy of GA4's default channel group that you can edit: add channels, change conditions and reorder them. Traffic goes to the first channel whose definition it matches. Standard properties can have two custom groups, 360 properties five, each with up to 50 channels. Google says custom groups can be applied to reports retroactively.

D

De minimisCross-border & sourcing: The US administrative exemption that let shipments valued at $800 or less enter free of duty and taxes with minimal paperwork. Suspended for goods from all countries since August 29, 2025.
Decision-tree chatbotPlatform & products: A support tool that matches user input against pre-built trigger phrases or menu choices and returns a scripted response or path. It cannot answer anything outside the tree it was given.
Decoupled systemShopify: Two systems that exchange only a narrow, well-defined set of signals rather than sharing full access to each other's data - so a change or failure in one does not cascade into the other, and neither system accumulates data it doesn't need.
Default channel groupGEO & AI search: GA4's built-in set of rules that sorts every session into a channel such as Organic Search, Paid Search, Referral, Direct or AI Assistant, based on source, medium and campaign. Google says you can't edit it. You can copy it into a custom channel group and change the copy.
Direct checkoutPlatform & products: A Shopify-powered checkout that runs inside an AI channel, so the shopper pays without leaving the conversation. It's on by default for eligible stores on Google AI Mode and Gemini, Microsoft Copilot and Meta. ChatGPT has none: Shopify sends ChatGPT buyers to your online store checkout.
Double opt-inGrowth & retention: A signup flow where the subscriber confirms their address by clicking a link in a confirmation email before receiving any marketing. It verifies the address is real and the interest is genuine - the foundation of sender reputation.

E

Engaged subscriberGrowth & retention: A subscriber who opened or clicked at least one email or SMS message within a defined recent window (commonly 90 days) — as opposed to a subscriber who is merely present on the list but functionally unreachable.

F

FBA vs FBMAmazon-specific: Two ways to fulfill Amazon orders. With Fulfillment by Amazon (FBA), you send inventory to Amazon's fulfillment centers and Amazon picks, packs, ships, and handles customer service and returns for per-unit fees. With Fulfilled by Merchant (FBM), you store inventory and ship orders yourself or through your own 3PL. Seller Fulfilled Prime is an FBM program that adds the Prime badge to self-fulfilled offers.
Featured OfferAmazon-specific: The offer Amazon shows with Add to Cart and Buy Now buttons in the Offer Display near the top of a product detail page. Amazon selects it by evaluating all offers for the product, may rotate between the best offers when none is clearly ahead, and shows other offers in the "Other sellers on Amazon" box and the all-offers page. Sellers have long called it the Buy Box; Amazon's help pages call it the Featured Offer.
Field data vs lab dataShopify: Field data is collected from real visitors' devices and connections (the CrUX dataset). Lab data is a single simulated run on synthetic hardware. Google evaluates your store on field data — so a lab score can flatter you while real shoppers suffer.
Fixed-scope logicAgency & delivery: A pricing approach where the deliverable list is defined up front (catalog attributes enriched to a named schema, structured data live on every PDP, agent trained and tested against a defined conversation set, checkout configured for the client's tax and fulfillment rules) and the fee is set against that list, not against hours worked.

G

GEO vs SEOGEO & AI search: SEO optimizes for ranking in a list of links; GEO optimizes for being the fact or product an AI assistant quotes or recommends directly, often without a click-through at all.
Google AI OverviewsPlatform & products: AI-generated summary panels shown above traditional results in Google Search, which can cite and link to product pages the way a human-written snippet used to.
GTINCatalog & data: The GS1 identifier behind UPC (GTIN-12), EAN (GTIN-13) and ITF-14 barcodes. It identifies a specific trade item, so the same product can be matched across retailers, marketplaces and shopping engines.

H

HydrogenShopify: Shopify's storefront toolkit for custom frontends. A Hydrogen project is a React Router app with Shopify API clients, components, and a CLI. It is Shopify's recommended way to build a headless storefront.

I

Importer of recordCross-border & sourcing: The party legally responsible for a shipment's entry into the US — accurate classification, duty payment, and compliance with every applicable regulation. For a South Asian exporter this is typically your US entity, or you as a foreign importer of record with a customs bond and a broker.
Instant CheckoutPlatform & products: OpenAI's in-chat purchase flow, launched September 29, 2025: a shopper taps Buy on an eligible product and confirms shipping and payment inside ChatGPT, while the merchant processes the order and payment on its own systems as merchant of record.
Intent-to-purchase ratePlatform & products: The percentage of agent conversations that include at least one purchase-oriented question — about a product, a comparison, fit, compatibility, or availability — as opposed to pure support or order-status queries.
ISFCross-border & sourcing: Also called '10+2' — a filing of shipment and party data that must be lodged with US Customs before ocean cargo is loaded at the origin port. Missing or late ISF filings carry monetary penalties and can trigger cargo holds on arrival.

K

Key eventGEO & AI search: GA4's name for an event you mark as important to your business, such as a purchase. Attribution reports and the Key events metric are built on them. For a store's revenue report, the purchase event is the one that matters.
Knockout searchCross-border & sourcing: A preliminary, non-exhaustive search of the USPTO's trademark database (and ideally state and common-law sources) to check whether an identical or confusingly similar mark already exists in your goods category, before you commit budget to a name.

L

Landed costCross-border & sourcing: The fully loaded cost to get one unit from the factory floor to a fulfilled US sale, including product cost, freight, duty, marketplace fulfillment fees, marketplace referral fees, and an amortized reserve for returns. It is the true cost basis for pricing — not the FOB or CIF quote.
Launch driftPlatform & products: The gradual mismatch between an agent's configuration and reality that sets in when nobody actively tunes it after go-live — catalog changes go unreflected, new question patterns go unanswered, and the agent that was accurate on day one becomes gradually less accurate with each week of neglect.
llms-full.txtGEO & AI search: A companion convention: a single file containing the full flattened text content of the mapped pages, so an AI system can ingest everything in one fetch. Useful for documentation sites; rarely worth maintaining for an ecommerce catalog that changes weekly.
llms.txtGEO & AI search: A proposed plain-text file at a site's root that summarizes what the site offers, aimed at giving AI crawlers a fast, structured entry point similar to robots.txt for search crawlers.

M

Machine-readable corroborationAmazon-specific: Restating and expanding a product claim in indexable text so an AI assistant can verify it against the title and bullets. A+ content is the natural home for this on Amazon: it has the space the bullets lack and the seller-controlled detail that reviews cannot provide.
Machine-visible trustGrowth & retention: The part of your operational performance an AI system can check from data: review content and recency, delivery promises, published return and shipping policies, and support outcomes that become public. Agents can't feel your brand; they can read your record.
Margin headroomCross-border & sourcing: The gap between a realistic US retail price and your fully-loaded landed cost, after accounting for marketplace fees, launch advertising, and a returns allowance — the buffer that lets a new listing survive its first unprofitable months.
Marketplace facilitator lawCross-border & sourcing: A state law making the marketplace — Amazon — responsible for calculating, collecting, and remitting sales tax on third-party sales. Every US state with a sales tax now has one, which is why marketplace-only sellers generally do not register state by state.
Merchandising agentPlatform & products: An AI system that actively curates, bundles, or recommends products on a merchant's behalf, going beyond answering questions into making merchandising decisions.
Merchant of recordPlatform & products: The business legally selling the product to the shopper: it takes the payment, owes the tax, issues refunds and handles chargebacks. In every agentic checkout we checked (ACP, UCP, Copilot Checkout, Perplexity's PayPal checkout), the AI company says the merchant keeps this role.
Merchant-owned checkoutPlatform & products: The model OpenAI moved to in March 2026: shoppers discover and compare products in ChatGPT, then complete the purchase on the merchant's own website or app. For Shopify stores, that's the online store checkout opened in ChatGPT's in-app browser.
MetafieldCatalog & data: Shopify's native mechanism for structured custom product data — a typed, named field (material, fit, dishwasher_safe) attached to a product, variant, or category, defined once and readable by themes, Search & Discovery filters, APIs, and AI surfaces.

N

native_commerce attributePlatform & products: A Merchant Center product attribute with one boolean sub-attribute, checkout_eligibility. Setting it to true opts an eligible listing into Google's "Buy" flow (native checkout) on surfaces such as AI Mode and Gemini. False or empty leaves it a standard listing. Google recommends adding it through a supplemental feed so the primary feed stays unchanged.

O

Off-site assistantPlatform & products: An AI assistant that recommends or discusses products outside the merchant's own storefront — ChatGPT, Claude, Gemini, and Perplexity are the primary examples merchants optimize for.
OpenAI Measurement PixelGEO & AI search: OpenAI's browser SDK for ChatGPT Ads. You install a script, initialize it with a Pixel ID created in the Conversions section of Ads Manager, and call oaiq("measure", ...) when a conversion happens, such as order_created for a purchase.
OpenAI product feedPlatform & products: A structured catalog file (or API stream) that a merchant shares with OpenAI so ChatGPT can index its products and show current price and availability. It follows OpenAI's published Products spec and is part of the Agentic Commerce Protocol.
opprefGEO & AI search: The OpenAI click reference appended to the end of a ChatGPT ad's landing page URL (for example ?oppref=gAAAAAb123). The Pixel captures it and stores it in a first-party __oppref cookie for 30 days; server events should pass the original value unchanged.
Option nameCatalog & data: The label for a variant axis on a Shopify product — Color, Size, Material — set independently per product unless you enforce a standard.
Option valueCatalog & data: The specific setting within an option — Navy, Medium, 100% Cotton — which must be spelled identically across every product that uses it, or an agent will treat Navy and Nvy as unrelated concepts.
Organic SearchGEO & AI search: The GA4 default channel for unpaid search clicks. A session lands here when its source is on Google's list of search sites or its medium is exactly "organic". Google's definition says it includes AI Overviews and AI Mode.
Owned channelGrowth & retention: A communication channel where you hold the relationship directly, such as email and SMS lists built on explicit consent, as opposed to rented reach (ads) or mediated reach (assistant shortlists). No algorithm re-ranks who receives your message.
OxygenShopify: Shopify's edge hosting for Hydrogen. It runs a worker-based JavaScript runtime, ships with the Hydrogen sales channel, and is included at no extra charge on paid plans. You can self-host Hydrogen elsewhere, but Oxygen is the default path.

P

Payout railsCross-border & sourcing: The path Amazon's disbursements take to your company account: a direct deposit in your home currency where Amazon supports it, or a USD account (your own US bank account or a payment provider's receiving account) followed by conversion and transfer home.
PIMCatalog & data: Product information management system — dedicated software for managing product data at scale, as distinct from using a platform's native fields for the same purpose.
Post-purchase Brand AgentGrowth & retention: A Microsoft Brand Agent (in beta) scoped to post-order conversations — order status, delivery issues, warranty, product care, and returns — with access to live order data and the merchant's enriched catalog.
Product attribute schemaCatalog & data: The per-category contract that names every attribute a product must or may carry, its data type, its allowed values, its unit, and whether an empty value blocks publishing. It defines what "complete" means for that category.
Product catalog enrichmentCatalog & data: The process of turning product facts into structured, validated fields (attributes, identifiers, variant data, offer and policy data) and keeping them accurate across every channel that reads them, so people and AI systems can filter, compare and quote them.
Product schema auditGEO & AI search: A scored review of Product (and related Offer / rating / policy) structured data on live product pages, measured as a crawler would read them, against a fixed field checklist weighted for AI shopping usefulness.
Product taxonomyCatalog & data: The hierarchical category structure a catalog is organized under, which agents use to scope what "kind" of product they're reasoning about before checking specific attributes.
Product typeAmazon-specific: Amazon's category-level schema that determines which attribute fields an ASIN carries, which are required, and which values are valid. Every audit starts by confirming each ASIN sits in the right product type — a miscategorized ASIN carries the wrong field set entirely.
Productized installAgency & delivery: A fixed-scope, fixed-price, fixed-timeline engagement with a named deliverable list, such as a configured Brand Agent, enriched priority SKUs, tested AI-channel checkouts and a measurement baseline, sold as a SKU rather than scoped from scratch per client.
Prose-trapped factPlatform & products: A true, useful product fact that exists only inside a marketing description rather than as a structured field — readable by a shopper, invisible to an agent's filtering logic.

Q

QBRMeasurement & delivery: A quarterly business review structured around agentic-commerce metrics specifically — citation rate, agent accuracy, TACOS — rather than generic traffic and conversion reporting.
Quotable contentGEO & AI search: Content written in short, self-contained, fact-dense sentences specifically because that shape is what AI assistants can lift cleanly into a generated answer.

R

Readiness checklistMeasurement & delivery: The step-by-step audit a merchant or agency runs through — catalog, structured data, checkout, and content — before flipping on a Brand Agent in production.
Referrer strippingGEO & AI search: When a visit arrives without the HTTP Referer header that names the page the shopper came from, because the source page, the link or the app withheld it. Analytics tools then classify the visit as Direct. It is the main reason AI traffic is undercounted.
Retrieval-augmented answerGEO & AI search: An AI response generated by first searching for relevant live pages, then having the model read and synthesize from those specific pages — as opposed to answering purely from training data. Perplexity's shopping answers are retrieval-augmented, which is why what's on your page right now matters more than what a model "knows" about your brand.
Rufus testAmazon-specific: A practical check, named before Amazon renamed the assistant, where a seller asks Alexa for Shopping the exact questions a shopper would about their listing, to see whether the assistant can answer accurately from the current product data.
Rule of thumbMeasurement & delivery: How GigaCommerce labels a working heuristic from its own delivery work — a number we use to decide where to start, stated as such, never presented as a measured statistic.

S

Search Query PerformanceAmazon-specific: A Brand Analytics dashboard that lists the search queries shoppers used to find your brand, with query volume and the impressions, clicks, cart adds and purchases your brand or ASINs earned for each, alongside the totals for the whole query.
Seller disbursementCross-border & sourcing: The scheduled payment Amazon makes to a seller's registered bank account, equal to gross sales minus Amazon's referral fees, FBA fulfillment fees, advertising spend, and any other deductions for that settlement period.
Semantic searchShopify: Search that matches the meaning of a query to the meaning of product data — usually via vector embeddings — instead of matching the literal keywords. "Couch" finds sofas; "something for cold mornings" finds insulated mugs and thermal layers.
Server-rendering disciplineShopify: The degree to which a theme writes facts — price, availability, variant options, key specs — directly into the HTML Shopify serves, versus assembling them in the browser after the page loads via JavaScript. High discipline means an agent fetching only the raw HTML still gets the complete picture.
Server-side renderingGEO & AI search: Generating the full HTML — including product facts and JSON-LD — on the server so it's present in the initial response, before any JavaScript runs. The opposite of client-rendering facts into the page after load.
Share in SQPAmazon-specific: At each funnel stage, your share is your brand or ASIN count divided by the query's total count for that stage. Ten purchases out of 100 marketplace purchases on that query is a 10% purchase share.
Shared foundationGEO & AI search: Technical and data work — structured data, attribute completeness, site architecture, page performance — that simultaneously improves classic search rankings and AI-assistant citation accuracy. It should be budgeted once, not split across SEO and GEO line items.
Shared Payment TokenPlatform & products: A Stripe payment credential an AI agent grants to a seller: a scoped, limited reference to the buyer's payment method, tied to the seller's Stripe profile with a maximum amount and an expiry. The seller charges it like a card and never sees the card number. OpenAI's docs call it the first implementation of OpenAI's Delegated Payment Spec.
Shopify Agentic planPlatform & products: A Shopify plan for merchants who don't use Shopify as their ecommerce platform. It adds their products to Shopify Catalog and lets them sell through agentic storefronts in AI channels, and on other Shopify channels such as the Shop channel, without a published Shopify online store. It has no monthly subscription fee; payment and app fees can apply.
Shopify B2BShopify: Shopify's native features for selling to other businesses from the same admin you use for direct-to-consumer sales. B2B buyers are set up as companies with one or more locations, and each location can get its own catalogs (products and prices), payment terms, tax exemptions, checkout settings and contacts. Shopify offers it on the Basic, Grow, Advanced and Plus plans.
Shopify CatalogPlatform & products: Shopify's standardized, enriched dataset of eligible merchants' products, made available to AI channels; eligibility starts at the Starter plan.
Shopify Catalog accessPlatform & products: The per-channel permission that lets an AI channel receive your product data (titles, descriptions, images, prices, availability) from Shopify Catalog. Turning it off filters your products out of what Catalog sends that channel. It doesn't remove your products from Shopify Catalog itself.
Shopify FlowShopify: Shopify’s free ecommerce automation app that runs workflows — a trigger, optional conditions, and actions — inside your store and across connected apps.
Shopify Knowledge BasePlatform & products: The Shopify-built admin app where you review generated FAQs, read buyer inquiries, and publish custom FAQs that AI shopping agents use when they answer policy, service, and brand questions.
Shopify MarketsShopify: Shopify’s built-in system for configuring how a single store sells to different countries or regions — currencies, domains, languages, catalogs, pricing, and duty settings — from one admin.
Shopify metafieldCatalog & data: A custom structured field on a Shopify product, collection, or variant — the mechanism most mid-market merchants use to add attributes without a separate PIM.
Shopify PlusPlatform & products: Shopify's enterprise tier, with the fullest checkout extensibility, unlimited and company-specific B2B catalogs and multi-store tools — not a requirement for Brand Agents, Copilot Checkout, Shopify Catalog or agentic storefronts.
Shopping-context alt textCatalog & data: Alt text written to answer a shopper's implicit question about that specific image — what product, which attribute, what context — rather than to maximize keyword density for search ranking.
SPAGAmazon-specific: A campaign structure in which each ad group contains exactly one ASIN (or one parent-child variation family treated as one unit), so every keyword, bid, and dollar of spend in that ad group maps to a single product with no blending.
SPAG PPC structureAmazon-specific: Single-product ad group structure, in which each ad group advertises exactly one product — the standard architecture for keeping Amazon PPC data clean enough to act on.
Structured attributeCatalog & data: A named, machine-readable field with a discrete value — material: leather, sleeve_length: short — as opposed to the same fact buried in a marketing sentence.
Structured dataGEO & AI search: Markup embedded in a page, such as Product or FAQPage schema, that tells both search engines and AI assistants exactly what a piece of content is, rather than making them infer it.
Structured-data parityShopify: The practice of auditing every schema type present on the old platform before migration and confirming each one exists, with the same fields populated, on the new platform after migration — treated as its own checklist item, separate from visual or content QA.
Substitution ruleGrowth & retention: A structured, brand-authorized statement of what an agent may do when a subscribed SKU is unavailable — reorder a specific approved alternate, ask the customer first, or decline and flag the gap. Without an explicit rule, an agent's only safe default is to stop and ask, which defeats the point of autonomous reordering.

T

TACOSAmazon-specific: Total advertising cost of sale — ad spend divided by total revenue (ad-attributed and organic combined) — the measurement Amazon sellers shift to once AI-influenced sales grow outside ad attribution.
Theme app extensionShopify: The modern (Online Store 2.0) mechanism Shopify apps use to inject blocks into a theme's sections, replacing older raw script-tag injection. Better for merchant control and removal, but still loads app JavaScript on render — consolidation still matters even on OS 2.0 themes.
Trust transferGrowth & retention: The degree to which a shopper's confidence in the AI assistant that recommended a product carries over into confidence in the brand itself, surviving past the first purchase into repeat behavior. High trust transfer looks like an organic-search-level or better repeat rate; low trust transfer looks like a one-and-done customer who reverts to asking the assistant again next time.

U

UCP integration hubPlatform & products: The onboarding area in Google Merchant Center where selected merchants choose which UCP capabilities to offer (cart transfer to their site, native checkout on Google, identity linking) and validate their UCP profile and APIs in a sandbox before going live.
Universal Commerce ProtocolPlatform & products: The open standard behind Shopify's Catalog, Cart and Checkout MCPs, which lets AI surfaces such as Microsoft Copilot complete purchases inside a conversation.

V

Variant dataCatalog & data: Structured attributes at the size, color, or configuration level rather than the parent product level — a common gap since many catalogs enrich the parent and leave variants blank.
Variant-level metafieldCatalog & data: A custom field attached to a specific product variant rather than the parent product — used for facts that differ by size, color, or material, such as weight, dimensions, or a fit note.

W

Welcome-list robots.txtGEO & AI search: A robots.txt posture that explicitly allows AI crawlers across discovery content — product pages, collections, guides, policies — while disallowing transactional and private paths. The deliberate opposite of the publisher default-deny.
White-label deliveryMeasurement & delivery: An arrangement where an agency sells agentic-commerce work under its own brand while a partner like GigaCommerce delivers the implementation behind the scenes.
WISMOGrowth & retention: "Where is my order?" — the shipping-status question that dominates post-purchase support volume. Trivially answerable by any system with live access to order and carrier state, which is exactly what most legacy chatbots never had.

Z

Zero-party dataGrowth & retention: Information a customer intentionally and proactively shares with you, such as preferences, intentions and context, as opposed to data observed from behaviour or bought from third parties. It is consent-clean and usually more accurate than inference.
Zero-results rateShopify: The percentage of site searches that return no products. Every zero-results page is a shopper who told you exactly what they wanted and got nothing — the most preventable lost sale in ecommerce.

#

1P vs 3P on AmazonAmazon-specific: 1P (Vendor Central) means Amazon Retail buys from you and resells to the shopper. 3P (Seller Central) means you sell directly to the shopper on Amazon's marketplace and pay Amazon fees for the privilege.
