Since everyone in the blogosphere is talking about how they see the big G screw them over on their sites, I have seen quite the opposite. Most of my sites went up in PR and even moved up some more spots in the SERPs. Why would this happen to me and not everyone else? No reason in particular. I take probably the same time, if not more, to do all my proper SEO and go through link values and site link structures. I take at least one day a week to go over my already established sites and try to see if I can go through and improve them even more. A little love goes a long way in SEO. How were you affected?
