GEO & AI search

Shared foundation

Definition

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.

Structured data: 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.
Citation: An instance of an AI assistant referencing or recommending a specific merchant, product, or piece of content in its response to a user query.
AI-attributed revenue: 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 Assistant channel: 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.
Custom channel group: 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.
OpenAI Measurement Pixel: 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.
