Free GEO, SEO and AIO audit for the AI search era
CiteSite analyses any website across six weighted dimensions and tells you how AI search systems — including Google AI Overviews, Perplexity and ChatGPT — are likely to discover, understand and cite it. The audit runs in seconds. No payment or subscription required.
What CiteSite measures
Modern search has split into two tracks: traditional link-based ranking and AI-generated citation. Most SEO tools only address the first. CiteSite addresses both. The audit evaluates six dimensions that determine whether an AI system will treat your page as a citable source:
- Structured data — the presence, completeness and validity of JSON-LD schema markup. Tells AI systems who you are and what your content describes.
- Content quality — clarity, depth and answerability. AI systems prefer content that directly answers questions in complete, well-structured prose.
- E-E-A-T signals — visible evidence of experience, expertise, authoritativeness and trustworthiness. The same framework Google's quality raters use.
- Entity coherence — how clearly the site establishes its named entities and their relationships to other known entities in the web graph.
- Technical accessibility — whether AI crawlers can actually read the page: SSR status, robots.txt, llms.txt, and response headers.
- Metadata quality — title tags, meta descriptions and Open Graph completeness. The first layer of signal any crawler reads.
Why GEO and AIO matter now
In a traditional search result, ranking on page one is the goal. In AI search, the goal is different: you need to be the source an AI chooses to cite. Being cited in an AI Overview or a Perplexity response is increasingly where discovery happens — and traditional SEO tools do not measure citation readiness. CiteSite does.
How to use CiteSite
Enter any URL into the audit tool above. CiteSite fetches the page, evaluates it against the six-dimension rubric and returns a scored report with prioritised recommendations. Each recommendation links directly to the relevant schema type, content change or technical fix required.
