Bid+ replaced by “Bids by Placement”
Bid+ has been replaced with ‘adjust bids by placement’. With Bid+, you could only set a 50% boost for the top of the search (first page) placement. With ‘adjust bids by placement’, you can set up to a 900% increase for the top of search (first page) as well as for product detail placements. Existing campaigns that used Bid+ are now automatically translated to new settings of bidding strategy = Dynamic bids – down only, and bid increase top of search (first page) = 50%. These campaigns will continue to perform in the same manner as before.
