This update is excellent as it has removed many automated link farming sites from results of relevent keywords, which I saw sending relevent web surfers over to second tier search engines, including but not limited to yahoo. I am glad google finally pulled out of its 6 month slump of spam results. I have lost alot of backward links myself, but my traffic is up 500%, which is confusing me. I spent alot of time during the last month or two building as many links as possible and expected to see a whole lot more backward links, but now there are less. However, my PR is still the same on all of my pages, but web hits are up. Confusing. Has there been a PR update that anyone has seen?
