What is Broken links visitors hit, and how do I fix one?

It's a list on your Analytics page of addresses on your live site that don't exist but that people (not scanners) reached 5 or more times this week, often from an old link on Google or another site.

Each one comes with Add a redirect, pointed at the page they most likely meant. Pick the right page and tap Add a redirect, and from then on that address sends visitors there. It's the same redirect you'd add under Settings → Search and redirects, and only the account owner can add one.

If the list isn't on your Analytics page, there's nothing to fix right now.
