Amazon's ad system is smarter matchmaking. The machine learning models rolled out across all store advertising by 2019 were built to make ads more relevant, helping shoppers find better products and letting brands spend more efficiently. Calling that manipulation ignores the real innovation: fewer wasted ad dollars and better results for everyone in the marketplace.
Amazon secretly rigged its own ad auctions, injecting fake "shill bids" to overcharge over 1.2 million advertisers, including 500,000 small businesses, by over $20 billion since 2019. Internal documents show Amazon employees knew advertisers trusted the system and deliberately hid price hikes, hoping sellers wouldn't notice. Those inflated costs got passed straight to consumers.
