I'm looking at a Wordpress plugin that grabs the search terms which which visitors come to a page, and then below the post, lists up to 10 of the search terms, each search term set with the hyperlink going to this same page.
For example, after the post, in the same position as people put the Related Posts lists, it might look like this:
Search Terms used to find this page: 1. webmaster world 2. webmaster tips 3. running a web site ...etc...
Each of these links point to the page on which they reside.
Does this violate any terms of service of Google's?
Probably not... often same page (anchor name) links are used for navigation of the page. On the other hand, the user will catch on pretty quick and, depending on their temperament, may stay or (most likely) go. That kind of "stick" doesn't work for me.
