Free Website SEO Checker

Enter any website for a deep SEO health score with 50+ checks, a grade, category scores, a prioritised fix list and an optional Google Lighthouse test.

What does the SEO checker look at?

The deep scan scores seven areas: technical SEO (HTTPS, redirects, robots.txt, sitemap, canonicals, 404 handling), on-page SEO (titles, descriptions, headings, keyword alignment, duplicates across pages), content quality (depth, readability, keyword use), links and images (broken links, alt text, formats, sizes), structured data and social tags, security and trust signals, and server speed signals. It also crawls a few extra pages and lists your top keywords. The optional Lighthouse test adds mobile Performance, SEO, Accessibility and Best-practices scores from Google PageSpeed Insights.
