Hey peepz, just thought I'd pick your brains again..

I was wondering if anyone else on here uses the link tracking features on their websites and if they find it useful?

I have seen some types of PPC keyword tracking where you can insert a key word into the html for a text link to help you track in the affiliate portal, and pinpoint which links are converting better.

Just find it kinda interesting to see if these are popular with u guys and if it's something I should look at doing..
