Site Crawler: Multi-Page SEO Audit in One Single Pass

A site crawl visits every page on your website — just like Google does — and records every SEO issue it finds. Missing title tags, broken internal links, thin content, duplicate pages — a crawl finds them all in one pass before Google penalises you for them.

What is a site crawl and why do you need one?

When Google visits your site, it starts at your homepage and follows every internal link it finds — visiting page after page, recording what it finds on each one. A site crawl replicates this process and shows you what Google sees: which pages are accessible, which have errors, and which have SEO issues that could be costing you rankings.

Why it matters: Most sites have technical SEO issues they are completely unaware of. Pages with missing title tags, internal links pointing to 404 pages, duplicate content, and thin pages are all common — and all invisible without a crawl.

Issues to fix first — in priority order

How to run your first site crawl

  1. Open the Site Crawler and enter your homepage URL
  2. Choose how many pages to crawl — 20 is enough for a first audit of a small site
  3. Wait for the crawl to complete — results appear as pages are processed
  4. Sort results by score to find your lowest-scoring pages first
  5. Fix errors (red) before warnings (amber) before recommendations (blue)
  6. Re-crawl after making changes to confirm improvements
Good habit: Set a monthly calendar reminder to run a 20-page crawl. It takes five minutes and catches problems before Google finds them.
