…But Marissa Mayer, who was then a Google vice president, said Google didn’t use click-through rates to determine the ranking for its own specialized-search sites, because they would rank too low, according to the staff report. Ms. Mayer is now chief executive of Yahoo Inc. A Yahoo spokeswoman didn’t immediately make her available for comment.
Instead, Google would “automatically boost” its own sites for certain specialized searches that otherwise would favor rivals, the FTC found. If a comparison-shopping site was supposed to rank highly, Google Product Search was placed above it. When Yelp was deemed relevant to a user’s search query, Google Local would pop up on top of the results page, the staff wrote.
Other regulators have found similar practices. European antitrust authorities in 2013 said Google had a different, “specialized” search algorithm for ranking its own content.
