Website Checker is a free online tool that audits any public website in seconds. Paste a URL, press run, and the scanner performs sixty automated checks against the live page, then an AI model turns the raw results into a readable report with strengths, weaknesses and concrete suggestions.
The backend fetches your page exactly like a browser would, inspects the returned HTML and response headers, and probes root files such as robots.txt, sitemap.xml and llms.txt. Every check produces a pass or fail result with a plain-language explanation, and each category is scored as a percentage so you can see at a glance where the site stands. Nothing is installed on your site and no account is required.
Search engines, browsers and AI answer engines all reward pages that are fast, secure and clearly structured. Fixing the issues this scanner surfaces improves your ranking, protects your visitors and makes your content easier for AI assistants to quote accurately. Run a scan after every significant change to catch regressions before your users do.
