Most advice on Amazon ads is too small-minded. It treats advertising as a campaign management problem, a bid optimization problem, or worse, a line item that finance should keep under control.
That framing is outdated.
If you're a CEO, head of ecommerce, or GM, Amazon advertising services shouldn't sit in your mind as a media expense alone. They sit at the center of market share capture, brand defense, new product velocity, and channel economics. The key decision isn't just which keywords to target. It's who controls the function, how success is measured, and whether the people managing it are rewarded for profitability or for activity.
Amazon itself tells you how serious this has become. Amazon reported $56.21 billion in worldwide advertising revenue in 2024, with a projection of $65.64 billion in 2025, and Marketplace Pulse notes Q1 2026 advertising-services sales at $17.24 billion, up 24% from the same quarter a year earlier, according to Statista's Amazon advertising revenue data. You don't build a business of that scale because brands are dabbling. You build it because advertising is now embedded in how products win on Amazon.
Amazon ads aren't a tax on selling online. They're a lever that decides who gets seen, who gets considered, and who gets displaced.
That's why most vendor selection goes wrong. Brands evaluate Amazon advertising services like they're hiring a technician. They compare dashboards, meeting cadence, and fee percentages. Those things matter, but they're secondary. The primary issue is whether your service model pushes the partner to protect contribution margin, improve rank quality, and allocate spend where it builds durable advantage.
A partner who only reports ACoS can look competent while overspending on branded traffic, neglecting creative, and ignoring retail fundamentals. A partner who understands the full business will force harder conversations. Are ads masking poor pricing? Is inventory availability sabotaging efficiency? Are you paying to hold share you should own organically? Are your campaigns expanding profitable reach or just harvesting demand you already created elsewhere?
Those are executive questions. They deserve executive attention.
Rethinking Amazon Ads Beyond a Line Item
Treating Amazon ads as a necessary expense is one of the fastest ways to lose ground. The brands that win don't ask, “How little can we spend?” They ask, “Where does paid visibility create the highest strategic return?”
That return isn't limited to immediate attributed sales. It includes defending branded search, accelerating launches, protecting shelf presence in crowded categories, and creating enough sales velocity to strengthen organic performance over time. If your team reduces Amazon advertising services to a weekly PPC report, they're managing symptoms, not the business.
Why the old view breaks
The old view says ads are mostly about lower-funnel conversion. That's incomplete. Amazon's own advertising business has expanded far beyond a narrow retail search product. Marketplace Pulse notes that Amazon defines advertising-services sales broadly across sellers, vendors, publishers, authors, and others, spanning sponsored ads, display, and video advertising, and estimated Amazon at 11% of total digital ad spending worldwide in 2024 in its analysis of Amazon advertising-services sales. That's not a niche performance channel. That's a major media platform.
Once you accept that, the management standard changes. You stop asking whether you “should run ads” and start asking how your organization will use Amazon advertising services to build a stronger commercial position.
What CEOs should care about
A CEO doesn't need to live inside campaign managers. But a CEO does need to know whether the advertising function is doing these jobs:
- Protecting demand you've already earned: If branded search results are weak, competitors will intercept buyers who came looking for you.
- Creating profitable discovery: Non-branded visibility matters most when organic rank alone won't carry the product.
- Supporting retail economics: Good advertising can't rescue bad pricing, weak conversion assets, or chronic stock issues.
- Improving decision quality: Ads generate demand signals. Smart teams use those signals to shape content, assortment, and launch priorities.
The wrong operating question
The wrong question is, “Who can manage our Amazon ads?”
The right question is, “Who can own the growth equation without hiding behind vanity metrics?”
Executive filter: If a service provider talks more about clicks than category position, margin protection, and retail constraints, they're too tactical for a serious brand.
That's the frame for every decision that follows.
The Amazon Advertising Services Toolbox
Amazon advertising services work best when you think of them as a toolbox, not a menu. Each tool has a different job. Confusing those jobs is expensive.
Sponsored Products for direct demand capture
Sponsored Products are the foundation for most brands because they put individual ASINs in front of shoppers who are already in buying mode. They're the workhorse for search visibility, launch support, and competitive conquesting.
Operational discipline is paramount. Amazon Ads runs on a CPC bidding model, so cost efficiency depends on the relationship between click-through rate, conversion rate, and bid strategy. Higher CTR and stronger conversion rates usually improve acquisition economics at a given bid, while weak keywords should be reduced or paused. Amazon-oriented guidance also favors a controlled daily budget first, then scaling based on weekly performance changes, as explained in Adsmurai's breakdown of how Amazon Ads works.
That means a bad listing makes paid media worse. If your main image, title, reviews, price, or inventory position are weak, Sponsored Products expose those weaknesses faster.
Sponsored Brands for portfolio control
Sponsored Brands are useful when one ASIN isn't the whole story. They let you present the brand, not just the product. That matters when shoppers compare options within a category and when you want to guide them toward a curated set of products or a Store.
Good operators use Sponsored Brands to shape consideration. Weak operators use them because the format looks impressive. There's a difference.
Use Sponsored Brands when you need to:
- Own more branded real estate: This limits competitor intrusion on high-intent searches.
- Support assortment strategy: Push complementary products instead of forcing every click into a single SKU.
- Reinforce positioning: Premium, functional, giftable, or category-specific messaging belongs here.
Sponsored Display and Amazon DSP for broader reach
Sponsored Display extends reach beyond standard search placements. Amazon DSP goes further, giving advertisers audience-based, programmatic options for broader reach and more advanced media planning. If your team needs a clearer view of DSP's role, this guide on Amazon DSP advertising strategy is a useful reference.
Amazon itself frames the platform far beyond last-click retail ads. It also positions Amazon Marketing Cloud as a privacy-safe, cloud-based clean room that supports custom analytics and audience building from pseudonymized signals, including Amazon Ads data and first-party inputs, in its overview of Amazon Marketing Cloud capabilities. That matters because once you use display, video, and audience strategies, you need better measurement than simple in-platform attribution.
The toolbox is only valuable if each tool has a defined commercial job. Don't buy reach when you need conversion. Don't buy conversion when the real problem is weak category presence.
The assets underneath the ads
Ads don't sit on top of nothing. They sit on creative and retail infrastructure.
Here's the blunt version:
| Asset | What it does | Why it matters |
|---|---|---|
| Amazon Store | Organizes the brand experience | Improves traffic flow and product discovery |
| A+ Content | Strengthens detail pages | Helps conversion and positioning |
| Creative for video and display | Makes upper-funnel formats viable | Poor creative wastes higher-order media |
| Catalog structure | Supports clean campaign design | Bad variation logic creates messy reporting |
A lot of underperforming ad accounts don't have a media problem. They have an asset problem.
Aligning Incentives The Three Engagement Models
Brands get this decision wrong because they shop for execution and ignore economics. Amazon advertising services are not a software subscription or a labor purchase. They are a set of incentives that will push your partner toward certain decisions when margin, growth, and budget start pulling against each other.
Choose the fee model first. It will shape the behavior you get.
Percentage of ad spend
This is the default model because it is easy to explain and easy to sell. It is also the model most likely to blur the line between account growth and agency revenue growth.
If a partner earns more every time spend rises, budget expansion becomes the path of least resistance. You will hear more about scale than about efficiency, incrementality, or whether the account has room to absorb more spend at an acceptable margin.
The predictable failure modes are easy to spot:
- Budget increases show up before retail fixes: Media gets pushed harder while pricing, content, inventory, or conversion issues remain unresolved.
- Low-quality spend gets defended as strategic: Waste gets relabeled as testing, defense, or category pressure.
- Brand campaigns absorb too much budget: They often make reporting look clean while adding less new demand than the dashboard implies.
This model can still work. But only with firm controls. Define contribution targets, review search term waste aggressively, and set explicit rules for pulling budget back when profitability slips. If you want a clearer view of the trade-offs, review these Amazon PPC agency pricing models.
Flat fee retainer
A retainer removes the agency's direct incentive to spend more media just to earn more fees. That is a real advantage, especially for brands that want cost predictability and disciplined account management.
It also creates a different problem. Once the account is stable, the agency gets paid the same whether it finds the next growth constraint or keeps the machine running. You may get steady management. You may not get hunger.
A retainer fits best when the account already has clear structure and the work is operational rather than focused on foundational change.
| Situation | Why it fits |
|---|---|
| The account is mature | The priority is control, consistency, and clean execution |
| Your team can manage the manager | Internal leaders can push for better analysis and challenge weak recommendations |
| Scope is tightly defined | Responsibilities are specific, measurable, and hard to dilute |
Retainers fail when the brief is vague and leadership expects aggressive growth without changing the incentive. If you want strategic initiative, pay for strategic initiative.
Performance-based structures
This is the strongest model when it is built correctly. It pushes the conversation toward business outcomes instead of media activity.
The key phrase is “built correctly.” If performance is tied to revenue alone, the agency can still chase unprofitable growth. If it is tied to ad-attributed metrics only, the model still rewards platform optics over business reality. The right structure ties upside to contribution margin, incremental sales quality, or another metric that reflects actual value creation.
That requires discipline from both sides. You need clean reporting, shared definitions, and agreement on what the partner controls versus what the business controls. Pricing, stockouts, conversion rate deterioration, and catalog issues cannot be dumped on the agency after the fact.
Practical rule: If the fee structure rewards spending more faster than earning more, expect media inflation.
Performance models also expose whether a partner wants accountability or just access. Good operators will accept scrutiny if the scorecard is fair. Weak operators avoid this structure because it limits their ability to hide behind activity.
My recommendation
Treat the engagement model as a governance decision, not a procurement detail.
- Use a retainer if Amazon is a stable operating channel and you need disciplined management at a predictable cost.
- Use a performance-oriented model if Amazon is a growth priority and you want your partner focused on incremental profit, not budget expansion.
- Use percentage of spend only with hard guardrails if the account benefits from flexible scaling and your team has the financial discipline to police it.
The right agency is not the one with the best pitch. It is the one whose compensation structure makes the right decision profitable for them too.
The Strategic Choice Agency Partner vs In-House Team
CEOs often frame this as a staffing decision. It is a profit architecture decision.
Choosing between an agency partner and an in-house team determines who owns expertise, how fast you can correct mistakes, and whether Amazon gets treated as a strategic growth channel or a neglected media account. Cost matters, but cost without capability is a trap. Cheap underperformance is still expensive.
When in-house wins
Build in-house when Amazon is important enough to deserve a true operating function, not a side assignment inside ecommerce.
That means dedicated ownership across the work that drives performance. Media. Catalog and content. Inventory coordination. Financial analysis. Someone also has to connect those pieces to pricing strategy, contribution margin, and executive priorities. If you cannot support that structure, you are not building an in-house team. You are hiring a bottleneck.
In-house tends to win in a few specific conditions:
- Amazon touches multiple departments every week: Product, supply chain, finance, and sales need tight coordination.
- Your catalog requires deep product judgment: Technical products, regulated categories, or highly varied SKU economics benefit from internal context.
- You want capability to compound inside the company: The goal is long-term channel ownership, not outsourced execution.
The weakness is coverage. Amazon performance comes from several disciplines working together, and one strong hire rarely brings all of them.
When an agency partner wins
A good agency partner is the better choice when your business needs capability before it needs headcount.
You get speed. You get pattern recognition from other accounts. You get specialists who have already seen the common failure modes, including wasted spend on low-quality query expansion, catalog issues that suppress conversion, and inventory decisions that wreck ad efficiency. That matters more than proximity if your internal team lacks Amazon depth.
Agency partners also win when Amazon suffers from weak ownership inside the company. That is common. The channel is large enough to matter, but not staffed well enough to improve. In that situation, an outside partner can impose operating discipline faster than a long hiring cycle.
Use an agency when the main constraint is expertise, pace, or executive attention.
In competitive categories, a weak internal team can protect process and still lose share month after month.
Key Decision Criteria
Ask one question first. Where is your capability gap, and what is it costing you each quarter?
Use this comparison to answer it:
| Decision factor | In-house team | Agency partner |
|---|---|---|
| Speed to impact | Slower. Hiring, onboarding, and ramp time delay results | Faster if the partner already has systems, specialists, and reporting in place |
| Channel knowledge | Deep on your products and internal constraints | Broader across categories, tests, and failure patterns |
| Control | Highest direct control over priorities and workflows | Strong enough with clear governance, weak if roles are vague |
| Specialist depth | Expensive to build across media, content, retail ops, and analytics | Usually available from day one |
| Institutional learning | Stays inside the business | Stays with the partner unless you document and transfer it |
| Executive leverage | Strong if leadership is engaged and the team is well-managed | Strong if the partner owns outcomes, not just task completion |
The deciding factor is management quality. An in-house team without senior oversight drifts. An agency without accountability sells activity.
My view
Build in-house if Amazon is already a major revenue driver, leadership is engaged, and you are willing to fund a real team instead of hiring one person and calling it a function.
Hire an agency partner if Amazon is under-managed, strategically important, or blocked by execution gaps your current team cannot close quickly. Use the partner to build momentum, create reporting discipline, and expose where internal ownership should eventually sit.
Avoid hybrid ambiguity. It creates split incentives, slow decisions, and easy excuses. Internal teams blame the agency. The agency blames pricing, inventory, or content. Nobody owns the result.
The best choice is the model that makes ownership clear and profitable behavior more likely. That is how you should evaluate a growth partner.
Measuring What Matters From ACoS to Contribution Margin
A lot of Amazon advertising services are sold on one promise. Lower ACoS.
That's not enough. In some cases, it's actively misleading.
A low ACoS can look great while the business gets weaker. You might be over-indexed on branded terms, under-investing in new customer acquisition, or starving launch campaigns that need temporary aggressiveness. Finance sees efficiency. The business loses future share.
This visual captures the mindset shift:
Why ACoS is too narrow
ACoS measures ad spend against attributed sales. That's useful for campaign management. It's not enough for executive management.
It ignores too much. It doesn't tell you whether the sale was incremental. It doesn't account for margin differences across SKUs. It doesn't show whether paid traffic is lifting organic rank or merely cannibalizing traffic you would have captured anyway.
Amazon itself is pushing the market toward broader measurement. Amazon's guidance increasingly emphasizes tools such as Amazon Attribution and Amazon DSP, and the discussion has shifted toward incrementality, halo effects, and the role of off-Amazon traffic, as outlined in Amazon Ads' guide to understanding Amazon advertising success.
What better measurement looks like
Good operators still watch ACoS. They just don't worship it.
They add more commercially relevant views:
- TACoS: Helps you judge paid media in the context of total sales, including organic impact.
- Contribution margin: Tells you whether ad-driven growth is leaving profit behind. If your team needs a better framework, this guide on how to calculate contribution margin is a practical place to start.
- Incrementality by campaign type: Separates demand capture from true demand creation.
- SKU-level economics: Not every product deserves the same aggressiveness.
Here's the strategic logic. A new product may justify a worse ACoS because you're buying visibility, reviews momentum, and ranking support. A mature hero SKU may deserve tighter controls because branded harvesting can make the account look healthier than it is.
A short explainer helps illustrate the shift in mindset:
The questions leaders should ask
Stop asking, “What's our ACoS?”
Start asking:
- Which spend is incremental and which spend is defensive?
- Which campaigns drive profitable new-to-brand reach versus branded recapture?
- Which SKUs create the best margin after fees, discounting, and media?
- Where are we spending to offset problems that should be fixed operationally?
A campaign can be efficient and still be strategically wrong.
That's the core issue. Measurement should tell you where to invest harder, where to defend, and where to pull back. If reporting doesn't help you make those calls, it isn't strategic reporting. It's dashboard theater.
Onboarding Governance and Partnership Red Flags
A strong Amazon advertising partner doesn't prove quality in the sales process. They prove it in onboarding and governance.
Bad partners rush into campaign changes before they understand the account. Good partners slow down just enough to diagnose the system. That includes ad structure, retail readiness, inventory reliability, conversion assets, and executive goals.
What good onboarding looks like
The first phase should establish access, clarity, and accountability. Not just ad account access. Full operating context.
A serious onboarding process usually includes:
- Commercial alignment: Clear targets around growth, profitability, and product priorities.
- Technical access: Advertising console, Brand Store access, reporting tools, catalog visibility, and any analytics environment that matters.
- Retail audit: Listing quality, A+ Content, pricing, review health, inventory history, and Buy Box stability.
- Decision rights: Who approves budget changes, creative, promos, and launch intensity.
If a partner starts talking about “quick wins” before they've checked catalog hygiene and stock reliability, they're guessing.
Governance is where partnerships survive or fail
Governance isn't bureaucracy. It's how adults run a growth function.
You want a structure that makes underperformance visible early and keeps strategic decisions out of email chaos. That usually means a live communication channel, recurring business reviews, and reporting that connects media outcomes to actual commercial outcomes.
A healthy governance model includes:
| Governance area | What to look for |
|---|---|
| Communication | Fast operating communication for day-to-day issues |
| Reporting | Transparent dashboards, not screenshot decks |
| Review cadence | Regular tactical reviews and less frequent strategic reviews |
| Escalation path | Clear handling for inventory shocks, budget changes, or listing issues |
Red flags I'd take seriously
Some warning signs are obvious. Others get ignored because the agency sounds polished.
Watch for these:
- Long lock-in contracts: Strong partners don't need handcuffs.
- Opaque reporting: If they can't show search term logic, placement thinking, and SKU-level decisions, don't trust the summary.
- Success defined by spend or attributed sales alone: That tells you exactly how narrow their model is.
- No questions about margin or operations: They're treating Amazon like a media sandbox, not a business.
- One point of contact who “does everything”: That usually means thin expertise and limited bandwidth.
The right partner welcomes scrutiny. The wrong one sells simplicity because transparency would expose weak thinking.
Your governance model should make it easy to answer one question at any moment: are we buying profitable share, or are we just funding motion?
The Ultimate Partner Vetting Checklist
Most agency sales calls are theater. Nice deck. Familiar jargon. A few screenshots. Maybe some selective wins.
Cut through that. Ask questions that expose how they think, how they're paid, and how they behave when trade-offs get uncomfortable.
Questions worth asking on the first call
Use these directly:
- How is your fee model aligned with profitability? If they can't answer cleanly, that's a warning.
- What metrics do you use beyond ACoS? You want to hear contribution margin logic, incrementality thinking, and SKU-level prioritization.
- How do you decide when to cut spend, not increase it? This reveals discipline.
- What retail variables do you review before changing bids? Good partners mention pricing, inventory, conversion assets, and Buy Box conditions.
- Who works on the account? Ask for role clarity, not titles.
- What data do you need from us to manage the channel properly? Serious operators ask for more than ad access.
Questions that reveal maturity
These go deeper:
- How do you separate branded demand capture from non-branded growth?
- How do you handle crowded categories where share is expensive?
- What would make you advise us not to scale budget right now?
- What does your onboarding process look like in the first month?
- How do you report on strategic trade-offs, not just performance outputs?
You're not just listening for answers. You're listening for posture. Do they sound like order-takers, or do they sound like operators with judgment?
What a strong answer sounds like
A strong partner is specific. They talk about decision frameworks, not slogans. They can explain how they use Sponsored Products differently from Sponsored Brands, when Sponsored Display or DSP is justified, and why creative or listing fixes sometimes matter more than bid changes.
A weak partner leans on generic confidence. They promise efficiency without asking about margin. They discuss growth without discussing governance. They sound certain before they understand your business.
“Show me how you make trade-offs” is a better vetting prompt than “What results can you get?”
That question forces substance. And substance is what you need from Amazon advertising services if the channel matters to your company.
If you want a partner that treats Amazon as a profit engine instead of a media line item, take a hard look at Online Brand Growth. They operate like channel owners, not dashboard vendors, with support across advertising, retail operations, content, logistics, and brand protection. For established brands that want tighter incentive alignment, stronger visibility into contribution margin, and a more hands-on growth partner, they're worth the conversation.
