Amazon's ad algorithm shift leaves sellers flying blind on PPC

Amazon's advertising system has gone through the same kind of transition Meta and Google went through years ago, and it has left sellers genuinely uncertain about how to make their PPC work.

The shift described by top ad spenders is threefold: away from manual keyword research toward algorithmic trust, from bid-and-budget mathematics to creative quality, and from mostly exact targeting to mostly broad.

Sellers spending millions a month on the platform say the change, combined with intensifying bid competition, is squeezing advertisers who built their playbooks on the old mechanics. Case material circulating in the community shows active sellers working through the adjustment in real time.

The pattern mirrors what happened on other ad platforms: as machine learning takes over targeting and placement, the levers that remain in human hands are creative, offer quality and feed data, and the sellers who adapt earliest tend to buy the cheapest clicks while competitors re-learn the system.

For Amazon advertisers, the practical implication is that granular keyword micromanagement is yielding to broader, creative-led campaigns, a bitter adjustment for operators who built careers on the old knobs.
