Definition
A GEO Audit is a structured assessment of your brand's presence in AI search across ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews. It is the GEO equivalent of a technical SEO audit, extended to cover citation behavior, crawler access, and AI-specific content signals.
A complete GEO audit covers four areas. First, visibility: AI search visibility, citation share, brand inclusion rate, and AI share of voice across a representative prompt panel. Second, content: whether pages are answer-ready, atomized, and structured for passage-level retrieval. Third, access: whether AI crawlers can reach your content, robots.txt and llms.txt are configured, and JavaScript rendering does not block retrieval. Fourth, authority: entity salience, third-party mentions, and topical authority.
You can start a GEO audit with the free AI SEO audit tool or the AI visibility report, then expand to continuous monitoring. The output should be a prioritized list of fixes: content gaps where competitors are cited, crawler-access blocks, freshness gaps, and missing entity coverage.
Re-run the audit quarterly and after major model or platform changes, since AI visibility shifts faster than traditional rankings.
Examples of GEO Audit
- A brand runs the free [AI SEO audit](/free-tools/ai-seo-audit) and discovers its robots.txt blocks OAI-SearchBot, eliminating its ChatGPT citations.
- A GEO team's audit finds the brand is mentioned in 40% of answers but cited as a source in only 12%, prioritizing linkable content.
- An audit reveals [content freshness](/glossary/content-freshness) gaps: pages not updated in 90 days lose citation share to fresher competitors.
- A quarterly GEO audit after a ChatGPT model rollout catches a citation-share drop and triggers a content refresh.
