Free website SEO audit

Check your whole website, not just one page. We follow your links and sitemap across up to 100 pages and list the broken pages, redirects, missing or duplicate titles and thin pages to fix first.

Audit a website

  • Free
  • No account needed
  • Up to 100 pages

What the audit looks at

  • Broken pages and redirects: links on your site that lead to errors, or that bounce through redirects first.
  • Titles and descriptions: missing, duplicated, too long or too short, page by page.
  • Headings and text: pages without one clear main heading, and pages with too little text to rank.
  • Images: pictures with no alt text.
  • Search engine settings: pages hidden with noindex, canonical tags pointing elsewhere, and what robots.txt blocks.
  • Sitemap: whether you have one, whether it lists every page, and whether it lists pages that are broken or redirect.
  • Speed and size: pages whose server is slow to answer, or whose code is very large.

What it doesn’t do

Paid tools like Semrush and Ahrefs also estimate search volumes, keyword difficulty, backlinks and traffic from their own databases. We don’t guess at those. Your real searches, clicks and positions are free in Google Search Console and Bing Webmaster Tools, and Bing’s data covers Microsoft Copilot too.

Want one page in more detail? Use the SEO check for a single page, or the AI readiness check to see whether ChatGPT and Copilot can read it.
