How to find and fix broken links

A broken link points to a page that no longer works — usually it returns "404 Not Found" or a server error. Visitors hit a dead end, and search engine crawlers waste time on pages that do not exist.

How to find them

Crawl your site and request every link it contains. Our broken links check does this and shows, for each broken link, the page it appears on, so you know exactly where to edit.

Fix each kind the right way

• Internal link to a page you moved: update the link to the new address, and add a 301 redirect from the old address so old bookmarks keep working.
• Internal link to a page you deleted: link to the best replacement page, or remove the link.
• Typing mistake in the link: correct the address.
• Link to another website that disappeared: link to a current source on the same topic, or remove the link.

Avoid redirect chains

If page A redirects to B and B redirects to C, update links and redirects to point straight to C. Each extra hop slows visitors down.

Some websites block automated checks and answer with 403 or 429 even when the page works in a browser. Our report lists these separately as "could not be reached" — open them yourself to confirm.
