Your Amazon ad console lies to you. Not maliciously — just incompletely. It tells you last-click attribution numbers. It shows you each campaign in isolation. It can't tell you whether a shopper saw your Sponsored Brand ad, bounced, got retargeted by DSP two days later, and then converted on a Sponsored Product. That path? The console credits only the last click.
Amazon Marketing Cloud (AMC) sees the whole journey. And if you're spending meaningful ad dollars and haven't touched it yet, you're making budget decisions with incomplete information.
What AMC Actually Is
AMC is Amazon's privacy-safe data clean room. It holds event-level, pseudonymized ad exposure and purchase data — Sponsored Products, Sponsored Brands, Sponsored Display, DSP, and streaming TV impressions — and it lets you run SQL queries across all of it together.
That sounds technical. Here's the plain-English version: AMC lets you ask questions like:
- "How many touchpoints did buyers see before purchasing?" (Most brands discover 3–5, not 1.)
- "Which campaigns are hitting the same audience over and over?" (Campaign overlap is the #1 reason DSP CPMs bloat.)
- "What percentage of my sales are actually new-to-brand vs. repeat buyers?" (Most sellers are shocked by this number.)
- "Which ASIN do shoppers buy first before upgrading to my flagship product?" (Your gateway product — often not what you think.)
The key insight: AMC doesn't change your ads. It changes which questions you can answer — and that changes every budget decision you make.
Who Should Actually Use It
AMC requires an active Amazon DSP account or Sponsored Ads campaigns generating enough event volume to be meaningful. Practically speaking:
- You're spending $10,000+/month across Amazon ad types
- You have at least a few months of campaign history to analyze
- You're running or considering DSP in addition to Sponsored Ads
If you're below $10K/month in ad spend, AMC exists but the signal-to-noise ratio makes the insights marginal. Fix your campaigns first. Come back when you're scaling.
Above that threshold? The competitive intelligence gap between sellers using AMC and those not is growing every month.
The Three Reports Worth Running First
You don't need to become a SQL wizard. AMC has pre-built query templates. Start with these three:
1. Path-to-Purchase Analysis
This query shows the sequence of ad touchpoints that preceded purchases. Most sellers discover their buyers saw 3 to 5 ad exposures before converting — often across different formats. If your attribution strategy only credits last-touch, you're undervaluing whatever introduced the shopper to your brand. This is especially important for Sponsored Brand ads and video, which rarely get last-click credit but often initiate the journey.
What to do with it: If SP gets all last-click credit but SB consistently appears 2–3 steps before conversion, you've been underbidding SB. Adjust accordingly.
2. Campaign Overlap Report
This shows how many unique users were exposed to multiple campaign types in the same time window. Industry benchmarks suggest consolidating 4–6 overlapping audiences into 2–3 distinct ones typically drops DSP CPM by 14–22%.
What to do with it: If 60% of your DSP retargeting audience already saw your Sponsored Display ad yesterday, you're paying twice to hit the same person. Suppress the overlap or shift budget to net-new audience segments.
3. New-to-Brand (NTB) Breakdown by Campaign
This splits your sales into new customers vs. repeat buyers — by campaign. It's the clearest measure of whether your ads are growing your brand or just rebuying existing customers.
What to do with it: If your NTB rate on Sponsored Products is 25% but on DSP it's 68%, you know which format is actually building your customer base. Brands that optimize for NTB acquisition cost instead of just ACoS grow faster and depend less on their existing buyer list.
Tip: AMC numbers won't match your Seller Central or ad console totals exactly — different attribution windows and aggregation rules. That's normal. Use AMC for directional decisions, not absolute revenue reconciliation.
How to Get Access
AMC is free to access through your Amazon Ads account, but it requires setup:
- Log into advertising.amazon.com
- Navigate to Measurement & Reporting → Amazon Marketing Cloud
- Create an AMC instance (links to your advertiser account)
- Historical data populates going back up to 13 months
- Start with pre-built templates before writing custom SQL
If you work with a PPC agency, ask them explicitly whether they're pulling AMC reports. Many don't unless pushed — it requires extra effort and not every tool supports it yet. The agencies that use it are making materially better decisions.
The Competitive Reality in 2026
Helium 10 and Jungle Scout can tell you which keywords to target. AMC tells you whether your campaigns are actually building the brand or just recycling the same buyers at full CPM cost. In a fee environment where every margin point matters, that distinction is worth real money.
Most sellers at $5M+ annual revenue are now using AMC in some form. Most sellers at $500K–$2M are not. That gap is where the edge currently lives.
Your action today: Log into your Amazon Ads account, find the AMC section, and run the New-to-Brand breakdown query on your last 90 days. The number you see — what percentage of your ad-driven sales are actually new customers — will tell you more about your growth trajectory than any ACoS number ever could.
