Adbrew vs Amazon Ads (AMS)

Adbrew is a third-party tool that automates and optimizes Amazon PPC campaigns, offering features like bid adjustments and keyword suggestions, but requires a subscription fee. Amazon Ads (AMS) is the native advertising platform where you pay only for clicks, with no additional subscription, but you manage campaigns manually. The key difference is that Adbrew provides automation and advanced optimization at an extra cost, while AMS gives direct control without recurring fees. For self-published authors, AMS is the standard entry point, while Adbrew may benefit those seeking to scale or complex ad strategies.
