What is a Broken Link?

You click a link expecting to land on a useful page. Instead you get a stark "404 Not Found" error. That is a broken link, and while it feels like a minor inconvenience as a visitor, for the website it lives on it is quietly doing damage in more ways than one.

A broken link is any hyperlink that points to a page that no longer exists or cannot be reached. It can happen when a page gets deleted, a URL gets changed without a redirect in place, an external site goes offline, or a typo creeps into the link itself. The result is always the same: a dead end for anyone who clicks it.

Why Broken Links Hurt More Than You Think

The most obvious problem is the user experience. A visitor who hits a 404 page loses trust in your site immediately and is likely to leave without finding what they needed. For a small business, that lost visitor could have been a potential customer.

The SEO impact runs deeper though. When Google crawls your site and repeatedly hits dead ends, it wastes crawl budget, the limited amount of time and resources Google allocates to crawling your site. More importantly, broken internal links cut off the flow of link equity through your site, meaning pages that should be benefiting from your internal linking structure are being starved of it instead. This is closely tied to what internal linking is and why every broken link in that chain is a missed opportunity.

Broken Links on Other Sites Matter Too

Broken link building is an overlooked but genuinely effective SEO tactic. It involves finding broken links on other websites in your niche that used to point to content similar to yours, then reaching out to suggest your page as a replacement. The site owner gets a fix for their broken link, and you earn a backlink. It is one of the more practical ways to build links without cold pitching from scratch, and it connects directly to whether backlinks are still important in modern SEO.

How to Find and Fix Them

Free tools like Screaming Frog, Ahrefs, or Google Search Console can identify broken links across your site quickly. The fix is usually straightforward: either restore the missing page, update the link to point somewhere relevant, or set up a redirect so anyone landing on the old URL gets sent somewhere useful instead of a dead end.

Broken links are one of those small technical issues that individually seem harmless but collectively signal to Google that a site is poorly maintained. Fixing them is consistently one of the first things worth addressing when deciding SEO priorities for any site.
