Broken links hurt your site’s SEO rankings and damage your visitors’ experience. CacheHero is a plugin that monitors your WordPress site for any external links and stores local copies in case the link dies. When an external link goes down, CacheHero will automatically rewrite the URL link in your page or post to the locally cached version.
Here is an example of a dead link that CacheHero has automatically cached and then rewritten the link.
CacheHero is designed to be “set and forget”. It will work immediately upon installation and activation, but there are also some advanced settings such as blacklists of domains and extensions that you want the plugin to ignore (e.g. large video files).
