Transform a 404 to a list of related links with descriptions & view 404 logs. Don't irritate readers with dumb 404s, keep'em with you
This plugin also logs any and all 404 hits so that you can improve on them, with comprehensive information about the requested URL, the number of suggestions shown for that page, the referrer (i.e. the source) from where the user came, the time of hit and the keywords extracted for that page.
You can limit the search to just the content on your site, set a default prefix to the search query (for example in case you want to limit the search to some keywords). This provides your users with quality recomendations.
And keep your readers with your site and does not irritate them with dumb 404s.
This plugin should work out-of-the-box with most themes using the included 404 template.
You can also define your own to fine tune the look and feel to match your theme.
