After doing a little analysis from last night's PageRank update, it is clear to me that some ranking drops over the last few months were due to a PR drop. Of course, this will not apply to everyone, but it certainly explains much of the drops I have seen in the last couple of months. One normally rock-steady site flipped from number 1 to number 2, and while that site's PR did not drop, the competitor's site PR did rise. The fog has lifted. 🙂 Time to work on PR again. Excuse me, while I go do that. hehe.
