Broken Link Checker vs. Doing It by Hand: Is It Worth Switching?

Most teams don't switch to a tool for broken links (404 errors) until the manual version has already cost them something — an hour lost, an error shipped, a page that quietly slipped through unchecked.

Doing it by hand isn't wrong, exactly. It's slow, and slow is where mistakes hide. Only checking navigation and footer links while ignoring links buried in years of blog content, where most rot actually accumulates. And once a site grows past a handful of pages, checking by hand stops being a one-time task and becomes a recurring one nobody has time for.

What actually changes with a tool in the loop isn't the underlying work — it's how often you're willing to do it. Prioritize fixing internal broken links first — they're fully within your control and directly affect crawl efficiency across your own site. That's the real ROI: not the first check, but the tenth one, which by hand simply wouldn't happen.

Where manual still wins: a single one-off check on a small site, or a case specific enough that no generic tool would catch the nuance anyway. For broken external links in old content, either update to the current URL, link to an archive.org snapshot, or remove the link entirely. Past that scale, the time saved compounds fast.

The same logic applies to keyword Cannibalization Checker work — anything repetitive enough to get skipped is exactly what's worth automating first.

If you're weighing this for your own site, trying Broken Link Checker takes about the same time as reading this page.
