Amazon Marketing Cloud (AMC) was an enterprise-only tool until late 2024. Now any brand running Sponsored Ads or DSP can access it free, and we have spent the last 18 months figuring out when it actually moves decisions for mid-size brands versus when it is a vanity dashboard. This post is the operator answer for brands doing $100K-$2M/month on Amazon.
We will say upfront — most mid-size brands using AMC today are extracting maybe 10% of what is there. The tool is powerful. The setup is real work. And the brands seeing the biggest lifts are the ones treating AMC as a decision engine, not a reporting tool.
What AMC Actually Is, In One Paragraph
AMC is a clean room that joins your Sponsored Ads data, your DSP data, your Amazon Attribution data, and (if you sell on Amazon) your retail purchase data. You write SQL queries. Amazon returns aggregated, privacy-safe results. The output answers questions you cannot answer in the standard ad console — things like new-to-brand rate by audience segment, true incrementality of branded search defense, and cross-channel path-to-purchase across DSP and Sponsored Ads.
You need 50 conversions per query for results to surface (Amazon’s aggregation threshold). For most $100K+/month brands, that is not a barrier.
When AMC Pays For Itself
We have run AMC implementations for 24 brands in the $100K-$2M/month range over the last 18 months. The pattern of which brands extract value is consistent.
AMC pays off for brands that:
- Run Sponsored Brands + Sponsored Products + at least one DSP campaign (multi-product portfolio)
- Have a real audience segmentation question (e.g., “are our high-value SKUs cannibalizing each other in retargeting?”)
- Spend $15K+/month on Amazon ads (volume thresholds for query reliability)
- Have someone — internal or agency — who can write SQL or use Amazon’s pre-built query templates
- Are willing to act on findings, not just review them
AMC is wasted on brands that:
- Run only Sponsored Products on a single SKU
- Spend under $8K/month total
- Have no operational appetite to restructure campaigns based on findings
- Want AMC as a reporting layer rather than a decision tool
If you are in the first bucket, AMC will earn its setup cost in 60-90 days. If you are in the second, leave it alone for another year.
The 4 AMC Queries That Actually Move Decisions
We use about 18 AMC queries regularly across the client portfolio. Four of them are responsible for the majority of the decisions we change. If you are starting with AMC, start here.
1. New-to-Brand Rate by Campaign Type
The query joins ad-attributed conversions with the new-to-brand flag and segments by campaign type (Sponsored Products auto, Sponsored Products manual, Sponsored Brands, DSP).
The output tells you which campaign types are bringing in genuinely new customers versus harvesting existing demand. We routinely find that Sponsored Brands video has a 38-52% NTB rate while branded-search Sponsored Products has 6-11% NTB. That changes how you allocate budget.
Decision impact: typically reallocates 12-22% of ad budget toward higher-NTB campaign types within the first quarter of running this query monthly.
2. Path-to-Purchase Lag Analysis
This query maps the time and touch-count between first ad exposure and purchase. For most consumables, the median path-to-purchase is 4-9 days. For considered-purchase categories (kitchen, electronics, beauty hardware), it stretches to 14-28 days.
Why this matters: standard Amazon attribution windows are 7 days for Sponsored Products and 14 days for Sponsored Brands/DSP. If your true path-to-purchase is 18 days, you are systematically under-crediting upper-funnel campaigns. AMC lets you see the real number.
Decision impact: typically increases DSP and Sponsored Brands budgets by 18-31% once leadership sees the true attribution picture.
3. Incrementality of Branded Search Defense
This is the query we run on every new client. It compares conversion rates for users who saw branded Sponsored Products ads versus users who saw the same listings organically.
What we find consistently: for established brands, branded search defense ads have 22-38% incremental conversion lift — meaning 62-78% of those clicks would have converted anyway. That math changes how you think about a campaign type most brands consider “must-have.”
Decision impact: typically reduces branded-defense spend by 30-50% and reallocates to genuine demand-generation. We have not seen a single brand regret this reallocation over a 6-month window.
4. Audience Overlap and Cannibalization
For brands with 4+ active DSP audiences, the query measures how much the audiences overlap and how much each is incrementally adding versus eating the others’ attribution.
Mid-size brands typically run “site visitors,” “ASIN viewers,” “purchasers,” and “similar audiences” simultaneously. The overlap is 40-70% on most setups. The cannibalization is real.
Decision impact: typically consolidates 4-6 overlapping audiences into 2-3 distinct ones, drops DSP CPM by 14-22%, and improves true incremental ROAS.
The Mid-Size Brand Setup Sequence
For a brand doing $200K-$800K/month on Amazon, here is the sequence we recommend:
Weeks 1-2: Get AMC access provisioned through your Amazon Ads console. Run the pre-built query templates Amazon provides to validate data is flowing correctly.
Weeks 3-4: Run the four queries above. Document findings. Do not change anything yet.
Weeks 5-8: Pick the highest-impact finding and run an A/B campaign change against it. Most often this is the branded-defense reduction.
Weeks 9-12: Measure the change against pre-AMC baseline. If positive, lock in the change and move to the next highest-impact finding.
Quarter 2 onward: AMC becomes part of monthly portfolio review. Re-run the four queries every 30 days. Adjust allocations quarterly.
Brands following this sequence see TACoS improvements of 1.4-3.2 percentage points within 6 months from AMC findings alone. That is meaningful when you are spending $30K-$120K/month on ads.
What AMC Will Not Do For You
We are skeptical of AMC pitches that promise too much. Things AMC genuinely does not solve:
- Bad creative. AMC will tell you a campaign is underperforming. It will not fix the listing image stack or the A+ content driving the underperformance.
- Listing health issues. AMC measures ad performance. If your listings are losing the Buy Box 18% of the time, no query fixes that.
- Inventory and operational drag. Out-of-stock periods, suppressed listings, IPI score problems — all upstream of what AMC can help with.
- Strategic positioning. AMC tells you what is happening. It does not tell you whether you should be playing in a category at all.
If your ad performance is bad because your listings are bad, fix the listings first. AMC is a multiplier on a solid foundation, not a substitute for one.
The Threshold Where AMC Stops Being Optional
We see a clear threshold in the data. At $400K+/month in Amazon revenue with $40K+/month in ad spend, brands that do not use AMC are leaving 1.5-3.5 percentage points of TACoS on the table. At that revenue, that gap is $6,000-$14,000/month. The setup cost is paid back in the first month at scale.
Below $200K/month, the math is closer to break-even and we sometimes recommend brands focus operational attention elsewhere (creative, Subscribe & Save optimization, inventory planning) before investing AMC time.
Between $200K and $400K/month, it depends on portfolio complexity. Multi-SKU, multi-channel brands benefit at the low end. Single-SKU brands can wait.
FAQ
Is Amazon Marketing Cloud free?
AMC access is free for advertisers running Sponsored Ads or DSP campaigns. The cost is the analyst time required to write queries and act on findings — typically 8-16 hours/month for mid-size brands.
Do I need SQL knowledge to use AMC?
Not for the basic templates Amazon provides — those run with parameter inputs only. For custom queries answering specific business questions, yes, SQL is required. Most mid-size brands either learn the basics or work with an agency that does.
How does AMC differ from Amazon Attribution?
Amazon Attribution measures off-Amazon traffic driving Amazon conversions. AMC measures the full on-Amazon ad ecosystem at the audience-segment level. They answer different questions and many brands use both.
Can I use AMC if I only run Sponsored Products?
Technically yes, but the value is limited. AMC’s biggest insights come from cross-campaign-type analysis. Single-campaign-type accounts get 20-30% of AMC’s potential value.
How long until AMC findings impact P&L?
First measurable impact typically lands in months 2-3 after implementation, as campaign restructures take effect. Compounding impact builds over 6-12 months as more queries inform more decisions.
