GEO Research

Our GEO audits analyze hundreds of websites to identify real patterns about how AI assistants process, evaluate, and cite content. These findings are not theoretical: they emerge from audit data that reveals which technical signals impact visibility in ChatGPT, Claude, Gemini, and Perplexity.

Each analysis translates into actionable recommendations backed by concrete metrics like semantic_ratio, entity_density, and Schema.org coverage.

What we found on most sites

Semantic HTML and AI citations

Sites that correctly use article, section, header, and nav are significantly more likely to be cited by AI assistants than those relying on generic divs.

Schema.org makes the difference

Implementing structured JSON-LD (Article, FAQPage, Organization) directly correlates with greater visibility in responses generated by ChatGPT, Gemini, and Perplexity.

Clean heading hierarchy

A logical heading structure (h1 > h2 > h3) without level skips allows RAG systems to extract coherent fragments and cite them with proper context.

Accidental AI bot blocking

Most sites do not configure robots.txt for modern AI bots. GPTBot, ClaudeBot, and PerplexityBot are blocked by generic rules or simply not considered.

Content inaccessible to AI

Content rendered exclusively with client-side JavaScript, images without alt text, and unstructured PDFs represent missed opportunities for AI indexing.

Implications for your strategy

The most accessible optimizations are also the highest impact. Configuring robots.txt to allow AI bots, implementing semantic HTML, and adding basic Schema.org are changes most sites can make without restructuring their content. Our data shows that these three factors combined explain most of the difference between sites that are cited by AI assistants and those that are not.

Heading hierarchy and content structure are the next level of optimization. A document with logical headings and well-delimited sections allows RAG systems to extract relevant fragments without losing context, which increases the probability of accurate citations and correct attribution.
