How to Check External (Outbound) Links Automatically

Outbound links rot at roughly 5–10% a year. Here’s how to keep up.

1. External links break when other sites restructure or shut down.
2. Check outbound links on a schedule, not once a year.
3. Swap dead links for archived or updated sources.
4. Use rel attributes correctly on any links you replace.
5. Automate alerts so fixes take minutes, not days.
