Save your visitors from unhelpful 404 errors!

Instead of quickly giving up when a visitor reaches content that doesn't exist, make an effort to guess what they were after in the first place. This plugin will perform a search of your posts, pages, tags and categories, using keywords from the requested URL. If there's a match, redirect to that content instead of showing the error. If there's more than one match, the 404 template can use some template tags to provide a list of suggestions to the visitor.

See the Smart 404 homepage for more information.
