Amazon is making first-party customer data a much bigger part of its advertising system.
On September 28, 2026, Amazon launched a redesigned Ads Data Manager (ADM) experience that gives advertisers one central place to connect, organize, monitor and activate their own customer and conversion data across Amazon Ads.
Brands can bring in information from sources such as website activity, CRM audiences and conversion events, then combine those signals with Amazon's shopping, browsing and streaming intelligence for advertising, measurement and AI-powered optimization. Amazon Ads
The important change is not simply that Amazon accepts first-party data.
It is what can happen after the data arrives.
Amazon says Ads Data Manager can now feed signals into destinations including Amazon Marketing Cloud, Sponsored Ads, Display, Video, Audio and Amazon Ads Agent, creating a much more connected advertising ecosystem. Amazon Ads
At Adorbix, we see the opportunity like this:
YOUR CUSTOMER DATA + AMAZON SIGNALS → BETTER AUDIENCES → BETTER AI → BETTER MEASUREMENT → BETTER BUDGET DECISIONS
For brands, that could reduce one of Amazon advertising's biggest historical weaknesses:
Knowing a lot about what customers do on Amazon, but not always connecting that behavior cleanly with what those same customers do across the rest of your business.
Ads Data Manager is Amazon's centralized system for onboarding and managing first-party advertiser data.
First-party data is information collected directly through your own customer relationships.
Examples can include:
Amazon originally launched Ads Data Manager as a way to upload first-party information once and reuse it across Amazon advertising and measurement products.
The 2026 redesign expands that concept considerably.
Advertisers now get dedicated areas for:
Where data enters Amazon Ads.
Where advertisers manage quality, attributes, permissions and lifecycle.
Where those signals can be activated across Amazon advertising and analytics. Amazon Ads
That makes ADM less like a simple upload utility and more like a:
Amazon says advertisers can bring signals into Ads Data Manager through several methods.
These include:
No-code file uploads
Amazon Ad Tag
Amazon Ads API
and:
Third-party connector integrations. Amazon Ads
That means a sophisticated enterprise brand can automate data ingestion through APIs or customer-data platforms.
A smaller advertiser may be able to start with a simpler file upload.
This matters because first-party data historically required substantial technical infrastructure.
Amazon is trying to make the process more accessible to advertisers with different levels of data maturity.
Imagine your brand sells on Amazon and through Shopify.
Amazon knows what happens inside its ecosystem.
Your Shopify store knows what happens there.
Your CRM knows which customers:
Those systems historically exist separately.
Ads Data Manager creates a pathway for your brand's own customer intelligence to help inform Amazon advertising.
For example, you might have an audience consisting of:
Another consisting of:
Another consisting of:
Those audiences can become useful advertising inputs instead of sitting untouched inside your CRM.
Your first-party data is valuable.
Amazon's shopping signals are valuable.
The more interesting opportunity comes from combining the two.
Amazon describes Ads Data Manager as a way to strengthen advertiser first-party signals with its broader shopping, browsing and streaming signals, as well as Amazon ad technology and AI. Amazon Ads
Think about the difference.
Your CRM might tell you:
Customer bought our premium coffee maker.
Amazon may have additional context around:
What categories similar audiences research, browse and purchase.
Your website data might tell you:
Customer viewed running shoes.
Amazon signals may help advertising systems find other audiences with similar commerce behavior.
This is where first-party data becomes an optimization signal, not simply a remarketing list.
One of the biggest changes in Amazon advertising during 2026 is the rise of Amazon Ads Agent.
Ads Data Manager now connects directly into that AI-powered advertising environment. Amazon Ads
That is strategically important.
AI optimization is only as good as the signals guiding it.
Imagine telling Amazon:
Find more customers.
That's broad.
Now imagine feeding Amazon an audience composed of:
The system has a stronger signal about the kind of customer you value.
At Adorbix, we'd think about this as:
not merely:
Amazon expanded Brand+ in 2026 to support Audience Signals.
Advertisers can bring first-party audiences into Brand+ prospecting through Ads Data Manager and use those audiences as signals to guide Amazon's AI while still allowing the system to discover additional relevant customers. Amazon Ads
This distinction matters.
You are not necessarily telling Amazon:
Only advertise to these customers.
Instead, you can be saying:
These customers represent the kind of audience we value. Use that information when finding new opportunities.
That makes CRM data useful for:
not only:
Amazon has also added Audience Signals to Performance+.
Advertisers can provide first-party audiences through Ads Data Manager to help guide customer-acquisition and consideration campaigns. Amazon Ads
That creates a powerful potential workflow.
Imagine your brand identifies:
Feed that segment into ADM.
Use it as an Audience Signal.
Allow Performance+ to look for incremental customers who share relevant characteristics.
The advertising question changes from:
Who clicked our ads?
to:
Who looks more like the customers who create the most business value?
That's a much stronger customer-acquisition strategy.
This is especially important for smaller Amazon sellers.
First-party data capabilities are no longer positioned only as sophisticated DSP functionality.
Amazon says Ads Data Manager is expanding first-party data activation across campaign types, including Sponsored Ads. Amazon Ads
That makes the opportunity more relevant to businesses that may never have operated a large Amazon DSP program.
A seller that primarily runs Sponsored Products and Sponsored Brands can increasingly participate in Amazon's first-party data ecosystem.
This is a significant democratization of ad-tech functionality.
Amazon's small-business guidance says advertisers using first-party data with Amazon Ads experienced approximately a 30% increase in ROAS compared with advertisers who did not.
That is an Amazon-reported aggregate result and should not be treated as a guaranteed outcome for every advertiser. Amazon Ads
The more useful takeaway is:
But first-party data only creates value when the data itself is useful.
Uploading:
does not automatically improve advertising.
The quality of the audience definition matters.
Imagine two first-party audiences.
Audience A:
But many are:
Audience B:
who:
Which audience is a better signal for acquisition?
Potentially:
At Adorbix, we'd prioritize:
AI needs to understand what “good customer” actually means to the business.
One particularly interesting feature in the redesigned ADM is the ability to work with custom business attributes such as lifetime-value scores. Amazon Ads
That creates a more sophisticated advertising model.
Instead of treating:
brands can communicate that some customer relationships are more valuable.
Imagine:
Customer A buys once for:
Customer B spends:
Traditional conversion optimization might value the first transaction similarly.
First-party LTV signals can help create a richer definition of customer quality.
For Adorbix, that means customer acquisition can increasingly be evaluated around:
not merely:
Uploading data isn't enough.
Bad data produces bad outcomes.
Amazon's redesigned Ads Data Manager includes a Datasets section designed to help advertisers monitor and diagnose the quality of the information being sent into Amazon Ads. Amazon Ads
Brands can manage:
This is important because data pipelines break.
Perhaps:
If AI is using those signals for optimization, data-quality issues can quickly become advertising-quality issues.
The more data advertising teams use, the more governance matters.
Brands need clear answers to questions such as:
Amazon says Ads Data Manager includes data controls and consent-management functions designed to help advertisers manage those responsibilities. Amazon Ads
But the advertiser remains responsible for following applicable privacy laws and policies.
For advertisers uploading data relating to users in the UK and European Economic Area, Amazon requires supported privacy-consent signals to accompany applicable data uploads.
Amazon currently lists mechanisms including:
This should not be treated as optional implementation detail.
If you are building first-party data activation in Europe, involve:
and:
early.
Adorbix can help structure advertising use cases, but brands should obtain appropriate professional privacy/legal advice for their specific obligations.
Ads Data Manager also feeds first-party signals into Amazon Marketing Cloud.
AMC is Amazon's privacy-safe analytics and clean-room environment where advertisers can combine Amazon Ads signals with their own pseudonymized data for deeper analysis and audience creation. Amazon Ads
That opens up much more sophisticated questions.
For example:
Do customers exposed to Streaming TV have higher repeat purchase?
Which first-party customers later interact with Sponsored Products?
Which website visitors become Amazon purchasers?
Which existing customers should be excluded from acquisition campaigns?
This goes well beyond standard PPC reporting.
One of the smartest first-party data use cases is often:
Suppose your goal is new customer acquisition.
Why pay aggressively to advertise to:
First-party audiences can help identify existing customers so brands can build suppression logic in supported advertising workflows.
That can potentially improve acquisition efficiency because more budget is directed toward incremental audiences.
This is a particularly valuable Adorbix use case.
Rather than asking only:
Who should we target?
we also ask:
Who should we stop paying to reacquire?
Ads Data Manager can also support Amazon AI and lookalike audience development. Amazon specifically highlights first-party signals as inputs that can strengthen programmatic optimization and audience modeling. Amazon Ads
The quality of the seed matters.
Instead of building a lookalike from:
consider creating one from:
Or:
Or:
A better source audience can create a better acquisition hypothesis.
Amazon's Amazon Ad Tag provides another route for first-party signal collection.
Brands can use it to send website activity and conversion information into Amazon Ads, subject to relevant privacy requirements.
The redesigned Ads Data Manager makes tag setup and signal management part of the broader Sources workflow, while Amazon is also expanding access to data-quality insights and manager-account capabilities. Amazon Ads
This can help connect:
Amazon advertising exposure
with:
off-Amazon website behavior.
For omnichannel brands, that's increasingly important.
Many Amazon brands also operate Shopify or another direct-to-consumer storefront.
Traditionally, the channels are analyzed separately.
Amazon says:
Shopify says:
CRM says:
Ads Data Manager begins creating infrastructure that can make those environments work together more intelligently.
At Adorbix, our preferred model would be:
not four disconnected marketing strategies.
Suppose someone visits your website repeatedly but never purchases.
That audience may represent:
Through a first-party data strategy, the brand may be able to activate supported audiences through Amazon Ads.
Now the shopper might encounter:
Amazon's commerce context adds another layer to the brand's own intent signal.
That is a much more sophisticated remarketing strategy than repeatedly showing the same Meta ad.
The strategy can work in the other direction too.
Suppose your product creates strong customer retention.
The real business objective is not simply:
It is:
By combining advertising signals with your own customer intelligence in AMC and ADM-supported workflows, a brand can increasingly evaluate which acquisition sources generate the strongest downstream behavior.
That changes media planning.
You may discover that:
creates:
That insight can be worth far more than another bid adjustment.
Subscription and replenishment products naturally benefit from LTV thinking.
Examples include:
A customer acquired today may purchase for years.
For those businesses, optimizing advertising around:
can be misleading.
First-party data gives Amazon's advertising ecosystem more context about:
That can help move acquisition strategy toward:
instead of:
Amazon's redesigned Ads Data Manager has broad international availability.
Amazon lists support across markets in:
including countries such as the United States, Canada, UK, Germany, India, Japan, Singapore, UAE, Belgium and Poland. Amazon Ads
Amazon says all Amazon Ads customers can access ADM through advertiser or manager accounts, with access also rolling directly into Amazon Ads Agent. Amazon Ads
That makes this a global advertising infrastructure update rather than a niche U.S.-only feature.
At Adorbix, we'd approach Ads Data Manager through five stages.
1. DEFINE
Determine what customer behavior actually creates business value.
Examples:
2. CONNECT
Bring relevant signals into Ads Data Manager through:
3. VALIDATE
Check:
4. ACTIVATE
Use signals across:
5. MEASURE
Ask:
That's the metric that ultimately matters.
Ads Data Manager is infrastructure.
The strategic value comes from deciding what data belongs inside it and how that data should affect advertising.
Adorbix can help with:
Audience Strategy: Define valuable first-party segments rather than uploading undifferentiated customer lists.
Amazon PPC: Connect first-party insights with Sponsored Ads strategy.
Amazon DSP / DVA+: Use audience signals for broader acquisition and remarketing.
Brand+ and Performance+: Supply stronger optimization inputs to Amazon AI.
Amazon Marketing Cloud: Analyze customer journeys and build advanced audiences.
Customer Acquisition: Separate new-customer spending from existing-customer reacquisition.
Profitability: Connect Amazon campaign results to LTV and contribution economics.
The objective is not:
“Upload all our data to Amazon.”
It's:
“Use the right first-party signals to make Amazon advertising smarter.”
Start with one clearly defined audience.
For example:
Document your existing acquisition performance.
Then onboard the audience into Ads Data Manager using the appropriate method.
Validate match quality and data health.
Use the audience as an input in one supported campaign strategy rather than changing every campaign simultaneously.
Compare:
Then decide whether the first-party signal deserves wider activation.
This gives you an actual experiment instead of simply adding another dataset to your tech stack.
Before activating first-party data, confirm:
Do not begin with:
“We have data.”
Begin with:
“What decision should this data improve?”
Ads Data Manager is Amazon Ads' centralized first-party data-management system. It lets advertisers connect, organize, monitor and activate their own audiences and conversion signals across Amazon advertising and measurement products. Amazon Ads
Amazon launched a redesigned ADM experience with dedicated Sources, Datasets and Destinations areas, expanded data-quality tools, more connectivity options and deeper activation across Amazon Ads Agent, AMC and advertising campaigns. Amazon Ads
Use cases can include audience data, conversion events, website signals and custom attributes such as LTV scores, subject to Amazon requirements and applicable privacy/consent obligations. Amazon Ads
Amazon supports methods including no-code file uploads, Amazon Ad Tag, Amazon Ads API and integrated third-party connectors. Amazon Ads
Amazon says signals can be activated across Amazon Marketing Cloud and campaign destinations including Sponsored Ads, Display, Video and Audio, with integration into Amazon Ads Agent. Amazon Ads
Yes. Amazon's Audience Signals capability allows first-party audiences from ADM to guide Brand+ prospecting optimization. Amazon Ads
Yes. Amazon allows first-party audiences to serve as optimization inputs for supported Performance+ acquisition and consideration strategies. Amazon Ads
Yes. AMC can combine advertiser-provided pseudonymized signals with Amazon Ads information for analysis and audience creation in a privacy-safe environment. Amazon Ads
No. Advertisers remain responsible for their own legal and privacy obligations. Amazon also has specific consent-signal requirements for certain UK and EEA data uploads. Amazon Ads
No. Amazon reports higher aggregate ROAS among advertisers using first-party signals, but individual outcomes depend on data quality, audience strategy, creative, product economics and campaign execution. Amazon Ads
Yes. Adorbix can connect Ads Data Manager with audience segmentation, Sponsored Ads, Brand+, Performance+, AMC, DVA+ and profitability analysis so brands use first-party data as a strategic advertising input instead of simply another customer list.
Amazon Ads Data Manager is becoming the central hub for bringing advertiser-owned customer signals into Amazon's advertising ecosystem.
The redesigned 2026 platform lets brands manage:
and:
from one environment. Amazon Ads
Advertisers can connect customer and conversion information using uploads, Amazon Ad Tag, APIs and partner connectors.
Those signals can then support:
Sponsored Ads
Brand+
Performance+
Display
Video
Audio
AMC
and:
Amazon Ads Agent.
The strategic advantage comes from combining:
to help AI understand which audiences actually matter to your business.
But first-party data is not automatically good data.
The brands that benefit most will have:
Amazon has extraordinary visibility into how customers:
and:
Your brand knows things Amazon may not.
You know:
Ads Data Manager creates the infrastructure for those two worlds to work together.
That changes Amazon advertising from:
“Find customers using Amazon's signals.”
toward:
“Use our best customer intelligence to help Amazon find better customers.”
At Adorbix, that's the opportunity.
We would not begin by uploading the biggest possible customer list.
We would begin by asking:
Then connect:
FIRST-PARTY DATA → AMAZON SIGNALS → AI OPTIMIZATION → MEASUREMENT → PROFIT
Because in an AI-driven advertising environment, better algorithms matter.
