I'm not really disappointed as I have learned so much SEO from you guys! But I asked a question recently and no one gave me a good answer on DP. It took another forum post elsewhere to get the correct info. I couldn't figure out why a Certain site had a PR of 3 but only 7 inlinks (bad ones at that) here is the thread: http://forums.digitalpoint.com/showthread.php?p=12293626 Well here is what someone found. The cache version of the site shows the .org version of the domain which means there used to be a 301 redirect. So explain this practice please?
It is hard to say with 100% certainty what all Google looks at when determining link quality, but I think you really want to look beyond raw PageRank score. As a measure of value of a link I think most people place far too much emphasis on PageRank. It’s more accurate to think of it as a floating-point number. Certainly Google's PageRank computations have many more degrees of resolution than the 0-10 values shown in the toolbar.
