The five signals behind your GEO score
- Extractability — can a model lift a self-contained, correct sentence out of the page without the surrounding context? Server-rendered text, direct answers and tight paragraphs win here.
- Evidence — concrete numbers, dates, named sources and outbound references. Answer engines prefer statements they can verify.
- Identity — who is speaking. Organization and Author schema, an about page, consistent naming across the web, and matching entity signals.
- Question coverage — whether the page actually answers the phrasings people type into an assistant, not just the keyword variants.
- Citability — quotable structure: clear headings, short definitions, tables, FAQ blocks, stable URLs and crawler access for GPTBot, OAI-SearchBot, PerplexityBot, ClaudeBot and Google-Extended.
Why AI visibility is a separate discipline
A ranking engine returns ten links and lets the user pick. A generative engine returns one synthesised paragraph and picks for the user. That changes what gets rewarded: not only relevance and authority, but how easy your text is to quote correctly.
This is why sites at position 3 in Google can be entirely absent from AI answers, while a smaller, cleanly structured site with schema and verifiable facts gets cited repeatedly. The full comparison lives in the SEO vs GEO guide.
Fix list ranked by impact
- Unblock AI crawlers in robots.txt and stop hiding answers behind client-side rendering.
- Open each section with the answer, then explain — inverted pyramid, not a slow build-up.
- Add dated, sourced numbers instead of vague adjectives.
- Ship Organization, Author, FAQPage and Breadcrumb schema.
- Publish an
llms.txtsummarising your site for models. - Cover the real question phrasings, including comparisons and "best X for Y" formats.

AI search visibility FAQ
What is AI search visibility?
AI search visibility is how likely an answer engine such as ChatGPT, Gemini, Perplexity or Copilot is to retrieve your page, extract a usable statement from it and cite you as the source. It is measured separately from Google rankings.
What is a GEO score?
GEO stands for generative engine optimization. The GEO score is a 0-100 rating built from five signals: extractability, evidence, entity identity, question coverage and citability.
Why is my site invisible in ChatGPT even though it ranks on Google?
Ranking rewards relevance and authority; answer engines additionally need clean, quotable statements, verifiable facts, clear entity markup and crawler access. A site that blocks GPTBot or hides its answers inside client-rendered JavaScript can rank well and still never be cited.
Does blocking AI crawlers hurt visibility?
Yes. If robots.txt blocks GPTBot, OAI-SearchBot, PerplexityBot, ClaudeBot or Google-Extended, those engines cannot use your content as a source, so you are structurally excluded from their answers.
How do I improve my GEO score fastest?
Answer one question per section in the first sentence, add verifiable numbers and dates with sources, publish author and organisation schema, cover real question phrasings, and make sure the answer exists in server-rendered HTML.
Is the AI visibility checker free?
Yes, it is free and requires no account. You can check your own domain in solo mode or compare it directly against a competitor.
