A product-first glossary

Clear definitions, without inflated promises.

14 terms

GEO

Generative Engine Optimization: organizing product evidence so it can be understood by generative engines. It is not a guarantee of recommendation.

AEO

Answer Engine Optimization: structuring content for answer systems. In Gengine, the focus remains product evidence, not an invented ranking promise.

Observation

One prompt × one provider × one repetition. Saved text is the evidence behind derived metrics.

Recommendation

A product indicated as a buying option in the saved answer, distinct from a mere mention.

Mention

A recognized product name in an answer; it does not necessarily recommend that product.

Citation

A reference or link supplied by the provider. A site citation is not automatically a product recommendation.

Readiness

Evidence-backed listing rule assessment. It is not observed visibility, sales or conversion.

Name variation

An alternative product name used in matching while preserving model and variant identity.

Shopping agent

An AI system that can assist purchase decisions or transactions, depending on its permissions and capabilities. Gengine does not make purchases.

Coverage

The share of rules supported by available evidence. Unknown values remain unknown; low coverage can suppress a score.

Valid answer

A completed usable provider answer included in the corresponding metric denominator. Truncated responses are separately flagged.

Snapshot

Captured listing content with source and capture time, used for extraction and re-audit without fetching again.

Listing

A channel/URL and seller offer, distinct from the canonical product identity.

Backtest

Chronological model evaluation on a later period than training, required alongside sufficient data before forecasts are shown.
