Amazon is now the third-largest digital ad platform globally, projected to reach US$60B in advertising revenue by 2026. For brands selling on Amazon, paid placement isn't optional — organic visibility on most product categories has been crowded out by Sponsored Products to the extent that 'organic ranking' is largely a function of paid sales velocity. Yet most brands run Amazon Ads as an afterthought to their Google and Meta programmes, by the same agency, with the same playbook.
Three patterns show up in every retail media audit. One: Sponsored Products campaigns running on automatic targeting only, with no exact-match harvesting from search term reports — burning budget on irrelevant queries that should be added as negatives. Two: bidding by ACoS target rather than TACoS (true ad cost of sales) — over-investing in keywords with high organic rank and under-investing in keywords with growth potential. Three: Amazon DSP either not deployed, or running on default audience segments without first-party customer data integration.
The platform economics are different. Click costs are settled at marketplace level, not auction level. Attribution windows are 7 or 14 days, not 30 or 90. Algorithms optimise toward unit sales, not click-throughs. Brand visibility and product detail page conversion rate matter more than landing page experience. Tactics that work in Google Ads actively underperform on Amazon.
Done right, retail media is one of the highest-margin channels in a media plan — for brands committed to learning how it actually works.
