GEO audit · free
Is your site ready to be cited by AI?
ChatGPT, Claude, Perplexity and Gemini answer people by citing the sites they can read and understand. Check for free whether yours is one of them: AI crawlers, llms.txt, structured data and extractable content.
GEO audit: find out if your site is citable by AI
Classic SEO moves you up Google's results. GEO (Generative Engine Optimization) does something different: it gets ChatGPT, Claude, Perplexity and Gemini to cite you in their answers. They're two separate games. A site can rank first on Google and stay invisible to AI, because its robots.txt blocks their crawlers or its content isn't extractable.
This free GEO audit checks exactly that. Enter a page URL and in seconds you get a score from 0 to 100 and 7 precise checks:
- whether AI crawlers (OpenAI's GPTBot, ClaudeBot, PerplexityBot, Google-Extended) are allowed in your robots.txt; - the llms.txt file that points AI at the right content; - JSON-LD structured data (Article, FAQ, Organization); - a single H1 and a clean heading hierarchy; - extractable content: lists, H2 subheadings and direct answers; - a filled-in title and meta description; - HTTPS.
AI cite the sites they can read and from which they can isolate a verifiable fact. A block in robots.txt rules you out from the start. A wall of text with no lists or H2s forces them to guess, and they don't cite you: the formats AI answers quote most are exactly bulleted lists and short paragraphs under an H2 that poses the question.
This isn't a generic technical SEO audit about speed and links: it's specific to AI citability. At the end you see which checks you pass, which you fail and what to fix first to make your site citable by AI.
FAQ
Frequently asked questions
What's the difference between a GEO audit and a normal SEO audit?
A classic SEO audit measures speed, backlinks and Google indexing. A GEO audit measures one thing only: whether generative AI can read and cite your page. It checks the AI crawlers allowed in robots.txt, the llms.txt file, structured data and content structure. You can have great SEO and zero AI citability, or the reverse: they are two different goals.
Why do AI cite some sites and not mine?
Usually for three reasons. One: robots.txt blocks GPTBot, ClaudeBot or PerplexityBot, so AI can't even read you. Two: the content is a wall of text with no H2s or lists, so the AI can't isolate an answer to quote. Three: there's no JSON-LD structured data to make the facts machine-readable. The GEO audit tells you which of the three applies to you.
What is the llms.txt file and do I really need it?
It's a text file at /llms.txt (like robots.txt) that tells AI which content on your site matters most to read and cite. It isn't mandatory and its absence doesn't block you, but it helps: in the audit it counts as a positive signal. If you don't have one, the check flags it as something to add, not as a serious error.
Is the GEO audit really free? Do I need to register?
Enter the URL and you immediately get, with no account, the 0-to-100 score and the first checks. For the full report with all 7 checks and the priority order of the fixes we only ask for your email. No credit card, no install, no software to download.
What should I fix first to get cited by AI?
Start with the worst block: if robots.txt shuts out the AI crawlers, unblock them, because without this no other check matters. Then make the content extractable with an H2 that poses the question and a direct answer in a list or short paragraph. Finally add JSON-LD schema (Article, FAQ, Organization). The GEO audit already ranks the checks by priority, so you know where to start.
