Amazon-specific
Corroboration layer
Definition
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.
Defined in Reviews as Machine-Readable Evidence on Amazon.
Related terms
- Corroboration
- 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.
- Browse node
- 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.
- Rufus test
- A practical check where a seller asks Rufus the exact questions a shopper would about their listing, to see whether the assistant can answer accurately from the current product data.
- SPAG
- 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.
- Product type
- 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.
- A+ Premium
- 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.
