Amazon Marketing Cloud (AMC) is Amazon's clean room: a secure environment where advertisers run SQL queries across their own Amazon Ads data, Sponsored Products, Sponsored Brands, Sponsored Display, DSP and, where available, retail signals, and receive aggregated, anonymized results. Individual shopper records never leave the room. AMC access has historically come with an Amazon DSP relationship, and audiences built in AMC are activated through DSP and increasingly through sponsored ads.
Why it matters
The ad console reports each format on its own, with last-touch attribution. AMC lets you see how the formats work together: how many shoppers saw a Sponsored Display ad before clicking a Sponsored Products ad, how long the path to purchase is, which combinations of exposure lead to the most new-to-brand buyers, and what a Sponsored TV campaign did to branded search. For a brand spending across several formats, that is the difference between guessing and knowing where the incremental sales come from.
AMC audiences are the second reason. Queries can define groups such as shoppers who viewed twice but did not buy, or who bought one product in the range but not its complement, and those groups become targetable audiences.
What moves it
- Data coverage. The more formats and the longer the history in the instance, the more useful the queries.
- Query design. AMC returns what you ask; the value is in asking the right question, such as path-to-conversion or frequency analysis.
- Aggregation thresholds. Results below a minimum audience size are suppressed, so small accounts get fewer answers.
- Activation. Audiences must be pushed to DSP or sponsored ads to do anything.
How we use it
For accounts already running DSP, we use AMC for two standing reports: overlap and path-to-conversion across formats, and the branded-search lift from upper-funnel spend. Both go into the monthly report. We also build audiences for repeat purchase and cross-sell campaigns where the catalog supports them.
