Internet Archive Wayback Machine Link Fixer is a WordPress plugin designed to combat link rot—the gradual decay of web links as pages are moved, changed, or taken down. It automatically scans your post content—on save and across existing posts—to detect outbound links. For each one, it checks the Internet Archive’s Wayback Machine for an archived version and creates a snapshot if one isn’t available.
When a linked page disappears, the plugin helps preserve your user experience by redirecting visitors to a reliable archived version. It also works proactively by archiving your own posts every time they’re updated, creating a consistent backup of your content’s history.
Protect your links, preserve your content, and automate the archiving process—all with minimal effort.

Internet Archive Wayback Machine Link Fixer


This has been working perfectly for me, and the only slight annoyance isn't the plugin's fault or even the Archive's fault.



Some sites block the Archive from archiving them, so they appear to the link checker as broken links too.



Give a quick look through broken links on your Dashboard's Posts section from time to time, as there might be a few you'll need to add to the Link Exclusions under Advanced Settings.



The benefits far outweigh the effort it takes to monitor that yourself. :)
