The Internet Archive Wayback Machine Link Fixer is a WordPress plugin that addresses link rot by automatically scanning post content for outbound links, checking for archived versions on the Internet Archive’s Wayback Machine, and creating snapshots if none exist. It redirects broken links to archived versions and archives your own posts upon updates, helping maintain content reliability and user experience with minimal overhead. The plugin works in the background using the Internet Archive’s APIs and supports managing large numbers of links, though it may have some compatibility and performance considerations.
