Does Broken Links (404 Errors) Still Matter in 2026?

Short answer: yes, but not for the reason it used to.

The old thinking was: Only checking navigation and footer links while ignoring links buried in years of blog content, where most rot actually accumulates. That framing is dated — search engines have gotten much better at figuring things out without hand-holding. But 'search engines can cope without it' isn't the same as 'it doesn't matter.'

What actually changed is who benefits. Prioritize fixing internal broken links first — they're fully within your control and directly affect crawl efficiency across your own site. That's less about appeasing an algorithm and more about not wasting the crawl/attention you already have.

The practical test isn't whether it's trendy — it's whether skipping it creates work for someone else later (a crawler, a future you, a user). By that test, broken links (404 errors) still earns its place.

Same question, different tool: does structured data (schema markup) still matter?

Broken Link Checker either way — checking takes longer to read about than to do.
