Broken links waste crawl budget, break the internal link graph that distributes ranking signals, and send visitors to dead ends. They accumulate silently as the sites you linked to reorganise.

Internal versus external breakage

Broken internal links are the more damaging kind: they interrupt how authority flows through your site and can strand pages with no working path to them. Fix these by updating the link, not by adding a redirect, wherever you control both ends.

Broken external links mostly cost credibility and user trust. Replace them with a live equivalent, or point at an archived copy if the original is genuinely gone.

Turning 404s into links

Broken-link building inverts the problem: find dead links on other people's pages that point at content you have a live replacement for, then tell them. It is one of the few outreach angles where the recipient genuinely benefits before you do.

Re-run a check after any site migration. Migrations are where most 404s are created, all at once.
