If you've ever sat in a budget meeting trying to reconcile two separate agency reports, you already know the problem. Paid social says it drove 40% of your sales lift. The agency handling retail media takes credit for most of the same conversions. You're paying twice, getting two conflicting stories, and still can't answer the question that actually matters: what's working?
The answer isn't a better attribution model (although that would be helpful!). It's a different operating model entirely.
Why Running Retail Media and Paid Social Through Separate Agencies Keeps Brands Stuck
The typical failure mode looks like this: your paid social team runs Meta and TikTok campaigns to build awareness and drive traffic. Your Amazon agency optimizes Sponsored Products bids and A+ content in a completely separate workflow. Neither team sees the other's audience data. Neither team coordinates creative messaging. And when a product launch underperforms, both teams can technically point to metrics that look fine in isolation.
Duplicated targeting wastes budget. Inconsistent creative messaging confuses buyers who see your brand on Instagram and then can't connect it to what they find on your Amazon listing. And attribution stays inconclusive because the signal that drove the sale may have started three touchpoints ago on a platform the other agency never sees.
"One place" doesn't just mean one invoice. It means one strategy owner who decides how Amazon DSP, Sponsored Ads, Meta, and TikTok work together before a dollar is spent. Shared audience planning. A coordinated creative brief. Budget allocation that shifts based on what the unified data actually says, not what each team's dashboard shows.
What it Actually Means for Brands to Manage Retail Media and Paid Social Together
A true full funnel agency manages the full scope in one connected workflow. Consider this example for a brand running on Amazon and social media: Amazon Sponsored Products, Sponsored Brands, Sponsored Display, and Amazon DSP on the retail media side, plus Meta, TikTok, and other paid social platforms on the demand-generation side. Creative and catalog management aren't optional add-ons, they're part of the system.
The integrated workflow runs in a consistent cycle:
- Audience planning starts with a single view of who you're trying to reach: new-to-brand buyers, lapsed customers, or high-intent category shoppers.
- Creative alignment means your social ads and your Amazon content tell the same story at each funnel stage.
- Launch sequencing coordinates timing so social awareness campaigns build before Amazon search campaigns scale into that demand.
- Optimization cadence runs on a shared weekly rhythm, not separate monthly check-ins.
- Reporting produces one set of KPIs, not two parallel reports.
The flywheel that drives results works like this: paid social touchpoints (Meta video, TikTok creative) generate demand signals and bring new shoppers into your brand orbit. Amazon capture ads, both Sponsored Ads and programmatic through DSP, convert that demand at the moment of purchase intent. Measurement from Amazon Marketing Cloud closes the loop, attributing conversion to the right touchpoint, not just the last click.
The Measurement Advantage: One ROAS Story Instead of Two Conflicting Reports
Silo reporting produces silo decisions. When your Amazon agency reports ACoS and your social agency reports ROAS using different attribution windows, you're comparing metrics that don't share a definition. Budget allocation decisions based on that data are unreliable.
Unified measurement starts with a shared KPI taxonomy: aligned attribution windows, agreed definitions of "incremental," and decision thresholds that determine when a campaign gets scaled or paused.
From there, Amazon Marketing Cloud adds a layer of depth that purely social-side agencies simply don't have access to. Code3 uses Amazon's first-party signals, cross-channel audience intelligence, and real-time event-level analysis from AMC to optimize programmatic campaigns. That data answers questions like: how many Amazon purchasers were also exposed to a social ad in the 14 days before they bought? Which audience segments convert via Sponsored Products after a DSP touchpoint versus without one?
A reporting setup worth trusting should include: weekly performance by channel with shared creative and audience notes, monthly incrementality read-outs where testing is active, clear action recommendations attached to every report (not just data), and a documented decision threshold for budget reallocation.
What to Look for in an Agency that Manages Amazon and Paid Social Together
Having Amazon and paid social under one roof doesn't mean the same strategist should run both. In fact, you probably don't want that. These are specialized disciplines that deserve specialized teams.
What you do want is a clear answer for how those specialists work together. Before choosing an agency, ask:
- How do your Amazon and paid social teams actually work together? Who connects the strategy across channels, how often are the teams sharing learnings and what decisions are made jointly?
- What Amazon insights make their way to the paid social team, and vice versa? Ask for a real example of an Amazon insight that changed a social strategy, creative brief or investment decision, or a social learning that changed something on Amazon.
- How deep is the Amazon expertise? Can the team manage Sponsored Ads and DSP, work within AMC and understand the retail-readiness factors that can affect advertising performance?
- Does the paid social team understand commerce? They should know how to build media and creative strategies around product discovery and purchase behavior, including purchases that may ultimately happen somewhere other than the brand's DTC site.
- How do they measure the relationship between channels? If someone discovers your product through social and buys it later on Amazon, how does the agency think about that journey without simply letting each platform take credit for its own conversions?
- How are budgets and opportunities evaluated across teams? If the next dollar would work harder creating demand through Meta than capturing existing demand on Amazon, or vice versa, can the agency recognize it and recommend accordingly?
- What does reporting actually lead to? Look beyond dashboards and reporting cadence. You want to know whether insights turn into decisions: a new creative test, a PDP update, a shift in media investment or a different audience strategy.
- Can they show you where this model has worked before? Ask for outcomes that demonstrate the benefit of connected Amazon and paid social expertise, not simply case studies proving they're capable of running each channel independently.
The goal isn't to find one person who knows everything about Amazon and paid social. It's to find specialists who are very good at their respective disciplines and an agency model that makes their expertise more valuable when it's connected.
What Results Look Like When the Model Actually Works
For a food and beverage client running an integrated full-funnel Amazon strategy, Code3 delivered 140% revenue growth year-over-year, 215% sessions growth, and 141% unit orders growth. Those aren't metrics from a paid social campaign or an Amazon campaign in isolation. They're the output of a system where both sides worked together.
Answers to the Objections You're Probably Already Thinking
"Won't Amazon cannibalize our paid social spend?"
Only if they're not coordinated. When audience targeting, budget sequencing, and attribution are managed together, social and Amazon ads serve different roles in the same funnel. Social builds reach and demand. Amazon converts it. The measurement tells you exactly how much each channel contributed.
"Can one agency really do both well?"
The right agency builds dedicated specialization within an integrated team structure. You're not getting one generalist trying to do everything. You're getting Amazon experts and paid social experts working within a shared strategy layer, governed by the same measurement framework and optimization cadence.
"What about constant platform changes on TikTok, Meta, and Amazon?"
That's exactly why continuous optimization matters more than a polished launch plan. A unified amazon dsp paid social agency with the right process and tooling monitors platform changes, adjusts creative and targeting in real time, and surfaces those learnings across both sides of the funnel in a single weekly workflow.
Ready to Stop Managing Two Agencies for One Growth Problem?
If you're spending on Amazon advertising and paid social but still can't answer "what's actually driving our sales," the structure is the issue, not the tactics.
A combined Amazon and paid social audit can map your current state: where audiences overlap, where creative is inconsistent, where reporting gaps are hiding your real performance. From there, a measurement-first integration plan coordinates both channels under one strategy with a clear launch timeline.
To qualify the conversation, it helps to come in with a sense of your current Amazon ad spend and paid social spend, what percentage of your revenue runs through Amazon, how many active ASINs you're managing, and what your current reporting setup looks like. That's enough to build a real integration plan, not a generic pitch.
When one team owns Amazon and paid social together, the whole system gets sharper. That's what it should look like.
