The Find Link tool - Add Wikipedia links to pages that really ought to have a link.
From Ewan McAndrew
The problem comes when pages that should have a link... don't.
The Find Link tool does a search for article titles/keywords throughout Wikipedia to highlight those articles that mention the search term and therefore ought to be linked to.
This can be the difference between articles that are easy to find and those that aren't. And therefore receive more pageviews as a result. Particularly if the high traffic pages link to your page.
Try it yourself!
