This trained the algorithm to be custom tailored for the use and probably was also fed into the overall ranking. They removed it, because it didn't prove to be valuable when compared to other metrics. Odd TC didn't include this information when writing this piece. Seems fairly relevant. EVERYTHING above fold was ads, not sure what you're talking about. Ads and probably most people didn't realize that they were ads. Google, no doubt A/B tested the text and colors to fool the users.
