The Amazon PPC DST Bug Costing You 15 Percent ROAS
Season 1
Episode 39
Published 1 month ago
Description
Lucas and Luna uncover a silent ROAS killer inside Amazon PPC: the campaign-level dynamic bidding setting that Amazon quietly defaults to 'down only' on certain new campaigns. Lucas explains how Amazon's 'dynamic bids down only' logic actually over-adjusts on high-converting placements, leaving advertisers paying more for traffic that would have converted anyway. Luna brings data showing a 15-year-old ecommerce brand that recovered 14.8% ROAS just by switching to 'dynamic bids up and down' and lowering their placement multiplier. They walk through the math, the auction mechanics, and why most advertisers never check that dropdown. Includes the 'buy me a coffee' donation segment mid-conversation.
