CiteCheck: SEO + AI Search Checker (GEO, AEO)

Evidence-weighted on-page SEO and AI citability checks. Every check shows its source. Runs 100% locally.

Know what search engines can index and what AI assistants can actually read and cite. CiteCheck audits the page you are viewing in one click. It covers classic on-page SEO plus the newer question of AI search readiness, and it does one thing no similar tool does: every check is labelled with its evidence strength and linked to its source, so you always know why something matters. WHAT ONE CLICK GIVES YOU On-page snapshot. Title, description, canonical and robots directives, heading structure, image alt coverage and social tags, ending in a plain-English verdict on whether the page can be indexed at all. AI crawler access. CiteCheck reads your robots.txt and shows which AI crawlers can reach the page. Crawlers that feed live AI answers are scored, because blocking them removes you from those answers. Crawlers that only gather training data are shown as information, since blocking those is a legitimate business choice. Each row names the crawler, who operates it and the exact rule that affects it. Entity consistency. Does your page agree with itself? CiteCheck compares your structured data against your visible content and against your homepage, then flags contradictions: duplicate schema blocks with different values, a brand name spelled two ways, a phone number in schema that never appears on the page. Contradictions like these quietly lower an AI engine's confidence in everything you say. AI citability. Practical extractability signals weighted by published research from Princeton and Georgia Tech. Does the page open with an answer an assistant like ChatGPT or Perplexity could lift? Does it back claims with figures, sources and dates? A render-gap check also reveals how much of your content is invisible to crawlers that never run JavaScript. THE HONEST DIFFERENCE Most AI-readiness checkers score things that make no measurable difference. CiteCheck labels every check as Documented, Research-backed or Consensus, with the source one tap away. We even check llms.txt but refuse to score it, because independent crawler-log research found almost no AI bot traffic ever requests the file. Tap any score to see exactly how it was calculated. Transparency is the product. PRIVATE BY ARCHITECTURE CiteCheck runs entirely on your device. No account, no analytics, no telemetry. Its only network requests are reads of the same site you are analysing, and it holds no standing site permissions: access is granted per tab, only when you click the icon. The install prompt shows no warnings because there is nothing to warn about. BUILT FOR PROFESSIONALS Quick checks in the popup, longer audit sessions in the side panel. Copy any report as Markdown, export raw JSON, or generate a branded client-ready report with your own name, site and colours, then print or save it as a PDF. CiteCheck is free, with no upsell inside the tool. Built by the team at Mackyclyde SEO.
