AI visibility & GEO glossary

Definitions of the terms used across GeoSuite reports and across this corner of the SEO/GEO industry. Each definition is meant to be quotable in one sentence so that when an AI engine cites it, the meaning travels intact.

Terms

AI visibility
How often and how favourably a brand is mentioned in answers from generative AI engines (ChatGPT, Gemini, Perplexity, etc.). The AI equivalent of a search ranking.
AI Overviews (AIO)
Google's generative-answer feature that appears above the classic search results for many queries. AI Overviews summarise sources from across the web and increasingly determine whether a user clicks through at all.
Attribute alignment
How closely the attributes a brand or product publishes match the attributes AI engines cite when answering buyer questions. Used inside GeoSuite's e-commerce audit.
Brand recall
Share of relevant generative-AI responses that mention the audited brand by name. The most fundamental AI visibility metric.
Buyer intent question
A question phrased the way a real buyer would ask it (e.g. 'best CRM for a small agency', not 'CRM software'). GeoSuite generates these per industry to drive realistic audits.
Citation sentiment
Whether an AI engine talks about a brand positively, neutrally or negatively, and on which attributes.
Competitor map
The ranked set of brands an AI engine names alongside or instead of the audited brand on a given set of queries. Output of every GeoSuite audit.
GEO — Generative Engine Optimization
The practice of optimising a brand's web presence so that generative AI engines cite, mention or recommend it when answering questions. The AI counterpart of SEO.
Grounding
When an AI engine retrieves live web pages while answering a query, instead of relying only on training data. Perplexity is always grounded; ChatGPT and Gemini ground selectively.
Lane
A class of buyer-intent questions GeoSuite audits separately because the optimisation playbook differs (comparison, recommendation, alternative, branded, feature).
PMF score
Per-product score in a GeoSuite e-commerce audit, weighting attribute alignment, query relevance, AI recommendation fit and market demand signal. Predicts which SKU an AI is most likely to recommend.
Recommendation fit
How strongly an AI engine recommends a specific product or brand when given a 'which X for Y use case' question.
Share of voice (SoV)
Proportion of AI mentions that go to the audited brand vs. its competitors on a given set of queries.
SoV by lane
Share of voice broken down per question lane — useful when a brand is strong on branded recall but weak on comparison or recommendation lanes.
Source list
The set of websites an AI engine cites when grounding its answers about a brand or its category. GeoSuite reports the source list per audit.
Structured data
Schema.org JSON-LD markup that lets engines (search and AI) extract the brand entity, products, articles and FAQ pairs from a page without parsing the HTML.
