Using the Broken Links Checker plug-in
The Broken Link Checker plug-in monitors your website and reports broken links to you.
The Broken Link Checker is a WordPress plug-in. This plug-in will monitor your entire WordPress site. It basically crawls through your entire website and searches for broken links (text or picture links to pages that can’t be found). It will monitor your pages, posts (and comments) during its monitoring. When broken links are detected, you are usually notified through the WordPress dashboard and via email.
How to fix broken links
After you have been notified that there are broken links, fixing the problem is incredibly simple. Instead of editing the specific pages or posts that contain broken links, you can solve the issue directly from the dashboard screen for the plug-in. Look for the tab in your dashboard called ‘Broken Links’.
This will contain the list of discovered broken links. Choose to edit the URL to fix a broken link. You can also choose to unlink the link. This removes the link while leaving the text that was linked intact.
If you are sure that a link marked as broken is in fact working, then you can manually tell the plug-in that the link is not broken. Your final option is to dismiss a notification of a broken link. The dismissed notifications will be ignored until its status is changed.
Use common sense
In most cases, you’ll need to check all broken links yourself and act accordingly. Sometimes a web page has a new address and the link simply needs updating.
In other cases, you may find that the page is no longer available, in which case you’ll need to delete the link (and it’s corresponding text). In some cases you may need to consider deleting the entire page or post.
