The wordpress 404 notifier might sound a bit weird, but it’s very, very useful. As your blog develops, you may decide that the original way it was created needs to be adapted. So, you change some categories, or the permalinks structure. No matter the size of your site though, the last thing you want are dead end links, or 404 pages, appearing after you do these changes.
Grab the 404 notifier plugin, and you’ll be emailed (or via an RSS feed) with a list of problems and 404 pages that need to be addressed to keep the site ship-shape and in working order.
An essential house keeping tool.
