SEO Web Checker

About SEO Web Checker

SEO Web Checker is a large free-tool site anchored by a website SEO audit that runs 50+ technical and on-page checks — meta tags, H1 structure, canonical tags, anchor text, Core Web Vitals and page speed — from a URL with no login required. Around that audit sits a toolkit the vendor counts at over 1,100 utilities, organised into coherent groups rather than dumped in a list: keyword and content tools (long-tail keyword generator, content-optimisation brief, keyword density and stuffing checkers, word counter, guest-post lookup), technical SEO (third-party script scanner, DNS lookup, URL slug generator, similar-website finder, web speed test, disavow-file generator, hreflang generator), and link and site tools (orphan-page checker, schema markup generator, HTTP/3 test, GZIP compression test, Google cache check, bulk URL opener). A separate AI section carries a blog generator, AI detector, summariser, email and essay writers, title-tag generator and, relevantly for this catalog, an AISO audit that checks how a page reads to AI search. There are also developer, encryption, networking, JSON, image, colour, audio, video and domain utilities, plus an online compiler. The free tier is genuinely usable and the paid step lifts audit and keyword limits rather than unlocking the tools themselves, which is the right shape for a utility site: most visitors arrive for one check and never register. Reports are detailed and mobile-friendly, and the audit runs instantly from a pasted URL with no email gate in front of the result.
