Why broken links hurt your SEO

404 errors waste crawl budget — Every time Googlebot hits a broken link, it wastes crawl budget on a dead end. Sites with many 404s get crawled less frequently — meaning new content takes longer to index.

Broken links lose link equity — If an external site links to a page that now 404s, that link equity (PageRank) is lost. Redirecting old URLs to relevant content reclaims that equity.

Redirect chains dilute authority — Each redirect hop dilutes the link equity passed through. A→B→C passes less equity than A→C directly. Audit and flatten redirect chains to one hop maximum.

User experience = ranking signal — Broken links frustrate users. High bounce rates from 404 pages tell Google your site provides poor user experience — which contributes to ranking drops over time.

Frequently asked questions

What is a broken link?

A broken link (dead link) is a hyperlink that points to a page that no longer exists or returns an error (usually 404 Not Found). They hurt both user experience and SEO.

How often should I check for broken links?

Monthly for active sites, quarterly for smaller ones. Every time you redesign a site or change URL structure, run a full broken link check immediately.

What's the difference between 404 and 301?

404 means the page doesn't exist — a broken link. 301 means the page permanently moved to a new URL — this is a redirect, not broken, but chains of 301s dilute link equity.

Should I fix broken external links?

Yes. Remove or update links to external pages that return 404. Linking to broken external resources makes your page look outdated and provides poor user experience.
