How it works
- Enter your site's URL (the homepage is a good starting point).
- The crawler fetches the page, discovers internal links, and crawls a batch of your most important pages in parallel.
- Each crawled page is parsed for technical issues, and outbound links are checked for broken (4xx/5xx) and redirected responses.
- Results are aggregated into a health score, an issue breakdown, and a per-page table so you know exactly where to act.
What it checks
- Broken links — dead links (4xx/5xx) found across the crawl that waste crawl budget and hurt UX.
- Redirect chains — links that resolve through one or more 3xx hops.
- Missing meta — pages with no title or no meta description.
- Heading structure — missing H1, multiple H1s, and H2 usage across pages.
- Image ALT text — images lacking descriptive ALT attributes.
- Thin content — pages with too little text.
- Indexability — pages accidentally set to
noindex.
Common use cases
- Monthly site health check — catch new issues before they cost you traffic.
- After a migration or redesign — the moment technical problems most often appear.
- Finding broken links at scale — across many pages, not one at a time.
- Onboarding a new site — get a fast, objective technical baseline.
Example
Crawl a small business site and you might get a health score of 67/100 across 12 pages: 3 pages missing meta descriptions, 2 pages with no H1, 8 images without ALT text, and 4 broken outbound links — each listed with the exact page so you can fix them one by one.
Frequently asked questions
How many pages does it crawl?
It crawls a batch of your most important internal pages discovered from the starting URL, which is enough to surface site-wide patterns quickly without a long wait. For deep single-page detail, pair it with the On-Page SEO Audit.
Can it find broken links and redirects?
Yes. It checks outbound links found during the crawl and reports dead links and redirect hops. For tracing a single URL's full redirect chain, use the Redirect & HTTP Status Checker, and for one page's links use the Broken Link Checker.
Is it really free?
Yes — no signup, no limits, real live crawling. Follow up with our technical SEO audit checklist to fix what it finds.
