What a GEO website audit covers
Four layers, in order. Presence: which of your buying moments name you across the four major assistants. Accuracy: whether the facts assistants state about you are true. Sources: which citations power the answers in your category, and whether you are in them. Readiness: whether your site's content, structure and entity data have the properties that earn mentions. A real audit outputs evidence, answer screenshots and a ranked fix list, not a score alone.
How to conduct a GEO audit, step by step
One: write twenty prompts from your buyers' real questions, several phrasings each. Two: run them through ChatGPT, Gemini, Claude and Perplexity, recording mentions, position, sentiment and every citation. Three: audit your own site against the readiness checklist below. Four: compare your citation presence against the sources the assistants actually used. Five: rank the gaps by revenue impact and cheapness of fix. A focused version takes one afternoon and reorders most teams' roadmaps.
The GEO audit checklist
Content: one page per high-value buying moment, direct answer in the opening lines, buyer phrasing in titles, follow-up questions covered. Structure: single H1s, question-phrased H2s, FAQ and Article schema matching visible text, real tables, visible dates. Entity: identical name, category, pricing and claims across site, directories, reviews and profiles. Authority: presence in the listicles, review platforms and communities assistants cite for your category; recent reviews; consistent press. Measurement: a fixed prompt set, re-run monthly, trends not snapshots.
GEO audit vs SEO audit: the difference
An SEO audit inspects rankings, crawlability, links and keywords against one index. A GEO audit inspects answers: whether four different assistants name you, what they claim about you, and which third-party sources drive it. The overlap is the technical foundation; the difference is that a GEO audit treats your presence across the rest of the web, citations, reviews, entity data, as first-class, because assistants weigh corroboration the way search engines weigh links.
