My website www.sovereignfunding.com
has a linking capaign that I am working on. A lot of the sites that want to link to me have great Google PR's but their link section url's often have an "?" in the url ie <a href="Finance-Companies.ht
inance Companies A-L</a> and I notice from that point on the url/links usually have no PageRank.
What is the "?" used for and why does it seem to degrade the PageRank?
