It's amazing, using Scroogle I have tons of keyword combos that have only a couple of changes in the first 100 results (0-3 from what I've seen) before and after. Yet, almost all of my popular ones (I.E. Britney Spears) are changed like 97 out of a 100. So it's definitely specific keyword targetting. All of the keywords and keyword combos that haven't been touched are all less popular ones. Thank god for those or I wouldn't be getting any traffic.
