AMC Custom Audiences: Precision Targeting for DSP
The DSP audience catalog is powerful but pre-packaged. AMC is where you stop picking from the menu and start defining exactly who you want — down to a behavior no ready-made segment can express.
Amazon Marketing Cloud (AMC) is a privacy-safe clean room where you build custom DSP audiences from raw shopping signals — segments the standard catalog can’t express, like “bought a complement but not your product” or “lapsed past the replenishment window.” You define them with SQL or no-code tools, then activate them straight into DSP. It’s what turns DSP from a catalog buyer into a precision instrument.
01What AMC is
Amazon Marketing Cloud is a privacy-safe clean room — a secure environment where pseudonymized signals from your campaigns and Amazon shopping activity can be analyzed without exposing individual user data. AMC does two distinct jobs: building custom audiences (this lesson) and advanced measurement (covered in Amazon Marketing Cloud). Here we focus on using it to define and activate audiences for DSP.02Why custom beats the catalog
DSP’s built-in audience catalog is broad and convenient, but it’s pre-packaged — you pick from segments Amazon defined. AMC lets you express logic the catalog simply can’t: combinations of behaviors, sequences, exclusions, and time windows specific to your business. That precision is the difference between advertising to “people interested in the category” and advertising to “people who viewed your hero product three times but bought a competitor.”03How AMC audiences are built and activated
The flow is: query the raw signals in AMC to define a set of shoppers, save that as an audience, then push (activate) it into DSP for targeting or suppression. You write the definition once, and the audience refreshes on a schedule so it stays current as shopper behavior changes. The whole process happens inside the clean room — you never touch individual user identities.04High-value audiences to build
| Audience | What it captures | Use |
|---|---|---|
| Cross-sell | Bought product A, not B | Promote complementary items |
| Win-back | Lapsed past the repurchase window | Re-engage former buyers |
| Deep-intent | Multiple views, no purchase | Convert high-consideration shoppers |
| High-value | Top spenders / repeat buyers | Reward and retain best customers |
| Competitor | Engaged with rival products | Conquest with a strong offer |
| Suppression | Recent buyers to exclude | Stop wasting spend on converts |
05The no-code path
You don’t always need SQL. AMC includes an audience builder with templated, no-code recipes for common segments — cross-sell, win-back, high-value, and more — that you configure with dropdowns. Custom SQL unlocks anything the templates don’t cover, but many valuable audiences are available without writing a query.06Activation and lookalikes
Once built, audiences activate directly into DSP for targeting or suppression (excluding recent buyers is one of the highest-ROI moves). You can also generate lookalikes — new prospects who resemble a high-value seed audience — to expand reach while keeping quality. Refresh audiences on a schedule so activation always uses current data. Measure the lift with new-to-brand and AMC path analysis.07What you need to use it
AMC custom audiences require an active Amazon DSP account (that’s where audiences activate), an AMC instance, and enough data volume for meaningful segments — clean rooms need scale to protect privacy and produce reliable audiences. It’s an advanced, mid-to-upper-funnel capability, so it fits brands already running DSP rather than beginners.08Why it makes DSP a precision tool
Standard DSP targets who Amazon thinks is relevant; AMC targets exactly who you define — by real behavior, in your own logic, refreshed automatically. That precision cuts waste, sharpens conquesting and retention, and unlocks suppression and lookalikes the catalog can’t. Paired with the measurement side of AMC, it turns DSP from a broad reach channel into a precision instrument.- AMC is a privacy-safe clean room for building custom DSP audiences from raw shopping signals.
- Custom audiences express logic the standard catalog can’t — combinations, sequences, exclusions, time windows.
- Build high-value segments: cross-sell, win-back, deep-intent, high-value, competitor, and suppression.
- Use SQL or the no-code audience builder; activate into DSP for targeting, suppression, or lookalikes.
- It requires an active DSP account, an AMC instance, and enough data volume — an advanced capability.
Frequently asked questions
What are AMC custom audiences?
They are DSP audience segments built in Amazon Marketing Cloud’s privacy-safe clean room from raw shopping signals — expressing logic the standard catalog can’t, such as cross-sell, win-back, deep-intent, or suppression. You define them with SQL or no-code tools and activate them into DSP.
What is Amazon Marketing Cloud?
AMC is a privacy-safe clean room where pseudonymized campaign and shopping signals can be analyzed without exposing individual user data. It does two jobs: building custom audiences for DSP and advanced measurement like path-to-purchase and incrementality.
Do I need SQL to build AMC audiences?
No. AMC includes a no-code audience builder with templated recipes for common segments like cross-sell, win-back, and high-value, configured with dropdowns. Custom SQL unlocks anything the templates don’t cover, but many valuable audiences need no query.
What do I need to use AMC custom audiences?
You need an active Amazon DSP account (where audiences activate), an AMC instance, and enough data volume for meaningful, privacy-safe segments. It’s an advanced capability suited to brands already running DSP rather than beginners.
What is a suppression audience?
A suppression audience is a segment you exclude from targeting — most commonly recent buyers — so you stop spending on shoppers who already converted. It’s one of the highest-ROI uses of AMC audiences.
