Baidu is finally saying goodbye to its eight-year-old bidding ranking system, the Beijing Morning Post reported. The reporter learned that Baidu has quietly closed part of the "bidding ranking" system yesterday (16) evening, and the Phoenix nest system began to take over the management rights of some of its keywords. Industry insiders believe that the move means that Baidu has accelerated the timetable for Phoenix Nest to replace the bidding ranking system.
