Find broken links without touching your 404 page

The 404s tab in the Pages card lists the missing URLs your visitors actually hit, with the page that most often sent them there. A link from your own site shows as a path, and a link from another site as its full address. That tells you whether to fix a link of yours or add a redirect for someone else's.

There's nothing to set up. When a visitor lands on a missing page, the tracker reads the 404 status from the browser and records it. No snippet in your 404 template and no goal to create. Chrome, Edge and other Chromium browsers report that status, while Safari and Firefox don't. So the counts run low, but one visit is enough to put a broken URL on the list.

A single-page app shows its not-found page without a new page load, so the tracker can't see a status there. Call track("404") from your not-found component instead.
