Free one-click SEO check for any website, plus what AI search can actually read on the page. A–F grade on every site you visit. CrawlCheck is a free SEO checker and AI visibility checker for any website you open. It grades the page from A to F the moment you land on it, so you can see how a site measures up without leaving the tab. Open the panel for the full picture. The SEO check reads the title, description, headings, canonical and structured data the page actually serves. The AI visibility check shows what AI search assistants can read on the page as opposed to what only appears after scripts run, and which parts they would miss. Both views come from your own browser, so the readings reflect what a real visitor connection gets. Add your own site to the watch list and the badge tells you when its grade moves, what changed, and how it compares with the sites you are watching. One click opens the complete report on crawlcheck.io, free, with every finding named and the first fix shown with its evidence. Pro adds the intelligence card: a daily read of your site and the competitors you choose, with price, review, service-area and script changes as they happen. No account is needed for the free check. The extension sends the hostname to look up its grade and, if you turn sharing on, signed page readings that help other site owners see what their site serves. It never sends page content, form input or browsing history.
