Wikipedia is based on wiki links leading from one article to another. If a concept is mentioned more than once in an article then it should be only be linked the first time it is mentioned.
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!
