Amazon's Ad Algorithm Changed. More Budget Now Makes Your ROAS Worse. Here's Why.

Amazon's ad platform has fundamentally changed. The old playbook of raising bids, increasing budgets, and winning more impressions is now actively working against you. CPCs are up 48% cumulatively since 2019. The algorithm no longer simply rewards the highest bidder. And more budget doesn't scale what's working. It gives Amazon permission to find traffic that doesn't convert.In this episode, I break down what the algorithm actually rewards in 2026 and why a 15% converter beats a 2x bid every time. I walk through the 3-week budget trap where week one looks promising, week two softens, and week three falls apart as Amazon floods you with low-intent traffic. I cover the reset mistake that sends your campaign back to Day 1, and why ACoS is the wrong metric to watch when TACoS tells you what's actually happening with your business.I also lay out the full diagnostic sequence you should follow in order before touching your budget. Start with creative and listing problems. Then bids. Then TACoS. Only then do you consider raising budget. Most sellers do this backwards and wonder why scaling makes things worse.If you're spending more on Amazon ads and getting worse results, it's not a budget problem. It's a conversion problem. Stop outspending.
