What this finds
- Broken internal links: links to pages on your site that return 404, 410, a server error or no response, each with the pages that link to them.
- Links to redirects: internal links that go through a redirect. They work, but linking straight to the final URL is faster.
- Broken external links: up to 20 links to other sites, checked politely.
- Server errors on crawled pages.
How to fix broken links
- The page moved: update the link to the new URL, and add a permanent (301) redirect from the old URL so other sites' links keep working.
- The page was removed: remove or replace the link. If the content is gone for good, the old URL can answer 410.
- A typo in the link: common in menus and footers, where one mistake appears on every page. The "linked from" count shows this.
- External links: sites move and close. Open the link in a browser first; some sites refuse automated checks but work for people.
Limitations
- The crawl covers up to 25 pages, 3 clicks deep. Links on pages it did not reach are not checked; the report lists what was skipped.
- Links added by JavaScript are not seen.
- Pages your robots.txt disallows for crawlers are not visited, so links on them are not checked.
