We all trade links with other blogs. When trading links often a simple link is added to the blog like:
<a href="http://www.mycoolblog.com">My Cool Blog</a>
Well that is cool and works fine. But most search engines like to know a bit more about a link so use the title tag to supply some more info about the link:
<a href="http://www.mycoolblog.com" title="Now this is one cool site">My Cool Blog</a>
It is preferable to put one sentence with 1 or 2 keywords you target in the title tag. It will do good for your search engine ranking.
But don't go abusing it like putting a keyword list in the title tag, cause that could harm your ranking.
That's it!
