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” holding pseudonymized records of your ad exposures and the shopping and conversion events tied to them. It does two jobs: measurement — path-to-purchase and incrementality analysis, covered in Amazon Marketing Cloud in Module 8 — and audiences, which is this lesson. On the audience side, AMC lets you interrogate those raw signals to define a segment, then push it into DSP as a targetable audience — all without ever seeing an individual shopper’s data.
02Why custom beats the catalog
DSP’s built-in audiences — in-market, lifestyle, remarketing — are strong, but they’re pre-defined buckets. AMC lets you express logic the catalog simply can’t: behavioral combinations (“viewed A and bought B but not C”), timing (“bought 45+ days ago and hasn’t returned”), sequence (“saw a video ad, then viewed the PDP twice”), and exclusions (“everyone except recent buyers”). That precision is the difference between renting Amazon’s generic segments and building the exact audience your strategy needs.
03How AMC audiences are built & activated
The flow has three steps. First, you write a query — in SQL or, increasingly, a no-code builder — that describes the audience by the signals that define it. Second, AMC assembles the segment from matching pseudonymized users, subject to a minimum audience size (so no one can be individually identified). Third, you activate it into DSP as a targetable audience, often set to refresh automatically as new shoppers meet the criteria. You work only with aggregate, activatable segments — never raw personal data — which is exactly what keeps it privacy-safe.
04High-value audiences to build
A handful of AMC audiences deliver outsized returns for most brands:
| Audience | How it’s defined | Use it for |
|---|---|---|
| Cross-sell | Bought a complement, not your product | Winning adjacent buyers |
| Win-back / replenishment | Bought a consumable, past its repurchase cycle | Bringing lapsed buyers back |
| Deep intent | Viewed your PDP repeatedly, never bought | Converting high-consideration shoppers |
| High-value | Repeat / high-frequency / high-AOV buyers | Retention & lookalike seed |
| Competitor | Bought or viewed a competitor ASIN | Conquesting |
| Suppression | Recent buyers | Excluding them from prospecting |
That last one — suppression — is quietly one of the most profitable: excluding recent buyers from prospecting stops you paying premium CPMs to reach people who already own your product.
05The no-code path
AMC used to demand SQL fluency, which put it out of reach for most sellers. That’s changed: Amazon has added instructional query templates and no-code audience builders that let you assemble common segments — cross-sell, win-back, suppression — from menus rather than code. You still benefit from an analyst for bespoke logic, but the barrier to the high-value audiences above is far lower than it was. If you’re on DSP and not building any AMC audiences, you’re leaving the platform’s best feature unused.
06Activation & lookalikes
Once built, an AMC audience becomes a normal DSP targeting option — you can bid on it, set its frequency, and pair it with the right creative like any other segment. Two power moves: use a high-value audience (say, your best repeat buyers) as a lookalike seed to let Amazon find similar new shoppers at scale, and layer suppression audiences across prospecting campaigns to keep spend focused on genuinely new customers. Activation is where the query becomes real spend efficiency.
07What you need to use it
AMC is bundled with Amazon DSP, so a DSP account is the entry requirement — this isn’t a standalone tool for console-only advertisers. You also need enough data volume for segments to clear the minimum audience-size thresholds, which means AMC audiences pay off most once you’re running real DSP spend with seasoned campaigns. Smaller or brand-new accounts may find their custom segments too thin to activate at first; they fill out as your data accumulates.
08Why it makes DSP a precision tool
Here’s the bottom line: AMC audiences are what separate a real DSP program from an expensive ad server. Anyone can buy Amazon’s catalog segments; the brands that win define their own — suppressing existing buyers, winning back lapsed ones, conquesting competitors, and seeding lookalikes off their best customers. If you run DSP through an agency and never see AMC audiences in your plan, that’s a fair thing to question. Next, we close the module by putting DSP and Sponsored Ads side by side.
- AMC is a privacy-safe clean room; on the audience side, it builds custom DSP segments from raw signals.
- It expresses logic the catalog can’t — combinations, timing, sequence, and exclusions.
- High-value builds: cross-sell, win-back, deep intent, high-value, competitor, and suppression.
- No-code builders and templates have lowered the SQL barrier significantly.
- AMC needs a DSP account and enough data volume; it’s what makes DSP a precision instrument.
Frequently asked questions
What are AMC custom audiences?
They’re DSP audiences built inside Amazon Marketing Cloud from raw shopping and ad-exposure signals, letting you define precise segments the standard catalog can’t — such as shoppers who bought a complementary product but not yours, or who lapsed past their repurchase cycle. You query them, then activate into DSP.
What is Amazon Marketing Cloud?
It’s Amazon’s privacy-safe clean room holding pseudonymized ad-exposure and conversion data. It does two jobs: measurement (path-to-purchase and incrementality analysis) and audience building (creating custom segments to activate in DSP). This lesson covers the audience side.
Do I need SQL for AMC?
Not anymore for common audiences. Amazon provides instructional query templates and no-code audience builders that assemble segments like cross-sell, win-back, and suppression from menus. SQL still helps for bespoke logic, but the barrier to the high-value audiences is much lower than it used to be.
Do I need DSP to use AMC audiences?
Yes. AMC is bundled with Amazon DSP, so you need a DSP account to build and activate custom audiences. You also need enough data volume for segments to clear the minimum audience-size thresholds, so AMC audiences pay off most once your DSP campaigns are running and seasoned.
What can you build with AMC audiences?
Precise behavioral segments: cross-sell audiences, win-back and replenishment audiences, deep-intent PDP re-viewers, high-value repeat buyers, competitor conquesting audiences, and suppression lists that exclude recent buyers from prospecting. You can also use any of them as a lookalike seed to find similar new shoppers.
