It is best to use text that is also an important keyword phrase for optimal search engine results.

This is something that the major search engines check for and if they find this approach being used then they may penalize the offending sites.
Overlinking - It is characterized by too many links from any given page on a website. It also may be an approach with the same term being overused on a webpage with the overused phrase also being a link.

Underlinking - This is the opposite of overlinking. An underlinked page can also be called a "dead-end page". This is a page with no links at all. This can be a bad tactic as you will want to provide a nice path for a human or a search engine spider to visit other relevant content on your site.
