Tips for Quality Backlinks
Title - Include keywords that your users will use when searching. Try to match keywords on your linked page to keywords in the title.

Link Type - Featured Links are located prominently in shallower pages. Search engines are more likely to see your backlink and more likely to assign your site a higher weight than free links.

Description - Write your description using plain english as if you were describing your site to a friend. Avoid making your description a steady list of keywords. Search engines call this keyword stuffing and generally ignore this tactic.

Category - Take the time to find the most descriptive category for your site. Search engines will take everyone's sites more seriously if it is included in a list of sites that deal with the same subject.
