Glossary
Fifteen GEO terms - citation, mention rate, share of voice, verification loop - defined the way Noetio audits and delta reports use them.
The terms audits and delta reports use, defined the way we use them. Fifteen terms, no padding.
GEO (Generative Engine Optimization)
The practice of improving how a brand appears in AI-generated answers (ChatGPT, Gemini, Perplexity, Google AI Overviews): whether it is mentioned, recommended, cited as a source, and described accurately.
AI visibility
How often and how favorably a brand appears when buyers ask AI engines category questions. Measured per engine, per query, over repeated runs.
Citation
An AI answer linking to or naming a source for its claim. Perplexity cites inline by default; ChatGPT cites when browsing; Gemini cites selectively. A brand can be mentioned without being cited, and cited without being recommended.
Mention rate
The share of runs of a query set in which a brand appears in the answer at all. The base metric of an AI-visibility audit.
Share of voice
A brand's mentions as a share of all brand mentions across a query set, compared against named competitors.
Hallucination log
The audit section recording factually wrong statements AI engines make about a brand (pricing, features, existence), each with the engine, prompt, and verbatim answer.
The Noetio verification loop
Noetio's method: audit (measure with repeated per-engine runs), fix (ship the prescribed changes), re-verify (re-run every original query on day 30, before and after, side by side). Defined in the re-run verification doc.
Buyer-intent prompt
A query phrased the way a real buyer asks an AI engine ('best CRM for a 10-person team'), as opposed to keyword strings. Audits run 30 of these per engagement.
Non-determinism
The same prompt returning different answers across runs. The reason single runs prove nothing and every Noetio number comes from repeated runs.
AI Overviews
Google's AI-generated answer block above organic results. Noetio audits check eligibility signals; most AI Overview citations come from pages outside the organic top 10.
llms.txt
A plain-text file at a site's root summarizing the site for AI systems, analogous to robots.txt for crawlers. One of the standard technical fixes audits prescribe.
Answer page
A page built to answer one specific buyer question well enough for AI engines to cite it. Noetio publishes and tracks its own as public proof the mechanism works.
Entity clarity
How unambiguously AI systems can resolve who a brand is: consistent naming, schema, and identity links across the sites engines index.
Citation vacancy
A query where engines cite no specialist source. Vacancies are validated with live runs before Noetio writes a page against one.
Delta report
The day-30 verification output: per query, per engine, mention and position before and after, with verbatim answers and screenshots.
