I guess they are trying the color out. I think it makes ads less noticeable and will lower click thru on sponsor ads.
I've seen this before i think... On the UK search engine... Last week i think... Unless I imagined it. But I'm sure...
While ever here on DP says that blending gives the best CTR, I pretty much disagree. No matter what niche site I have, it's always increased my CTR to make the ads stand out. The rule for me is, the uglier the layout is, and the more obvious the ads, the higher CTR
Oh sorry, didn't know that. For the record I'm in the U.S not U.K. Ehh screen resolution is crazy high for this monitor, I guess I forget some people are still stuck in the 1024*768 days
