It seems like Wikipedia is finally starting to take over search results in commercial sectors now [e.g. "jewelry", "laptop", "cell phones", etc]. Check for yourself. I've seen continued forward movement for some of the terms I've been monitoring recently. I know that many people will disagree with me, but I am firmly convinced that Wikipedia is becoming a cornerstone in Google's strategy of keeping AdWords ctr rates on the increase. What percentage of search users typing in the keyword "jewelry", are searching for historical facts on the subject written by some juvenile, my guess is the percentage is very low. Aside from the Wikipedia takeover, the general search results look like crap these days. It's no phenomenon that the only innovation Google can come up with these days is another type of search ranking penalty, all in the name of "stopping search spam" of course. Go ahead and believe that people, just turn a blind eye each quarter they break profit records. Sheeeeesh, enough is enough!
