Amazon Ad Auction Lawsuit: What Small Businesses Should Know
Amazon faces a lawsuit from 22 states and the FTC, alleging it manipulated its advertising auction system to overcharge over 1 million customers, including small businesses, by up to $20 billion. The lawsuit claims Amazon used fake bids and undisclosed pricing floors, turning second-price auctions into first-price ones. Amazon disputes the allegations, stating its average cost-per-click remained flat and winning bids fell 50% over a similar period.
