Why run an SEO audit?
According to Ahrefs, 96.55% of pages get zero traffic from Google. An SEO audit identifies technical issues, content gaps, and missed opportunities that prevent your site from ranking. CheckSEO scans 25 factors across 10 categories — from SSL certificates to structured data — and provides a scored report with actionable recommendations.
What makes CheckSEO different?
Unlike paid tools like Semrush or Ahrefs, CheckSEO is completely free with no trial period. The key differentiator is AI Readiness — 19 checks evaluating your site's compatibility with AI search engines. We check for llms.txt, Entity Schema, Speakable markup, sameAs links, citation passages, and more.
How the scoring works
Each of the 10 categories starts at 100 points. Points are deducted by severity: Critical issues cost 20 points, Warnings cost 10, and Info items cost 2. The overall score is a weighted average, with Technical SEO and On-Page SEO weighted at 15% each, while Performance is weighted at 2.5%.
