At the moment the ads I see are on a very different background. A client's site that I am doing at the moment has more traffic than ever despite having three ads above his #1 ranked phrase. One is bad statistics, but that is all anyone here seems to have.
Personally, I do not see that many ads on most searches, only for e-commerce ones - prefixing the word "buy" to a search often causes an add or two to move to above the organic SERPS.
