Hi, I have two clients that are business partners. They exchange links via a link tracking system so the links look something like this http://www.profcs.com/app/adtrack.asp?AdID=98715. It is my understanding that effective link exchanges work something like the following. <a href="http://othewebsite.com/keyword_or_phrase.html">Keyword Anchor</a> of course the two pages would have related content. It seems to me that the link tracker messes this up, is this the case? I feel like recommending that they stop using this system but I don't have anything to back that up. Does anyone know if these link trackers have negative effects on SEO? Thanks Rich
