Amazon Marketing Agency Checklist: How to Audit and Choose the Right Partner

An ideal Amazon marketing agency should be able to align advertising, SEO, catalog, creative, reporting, and marketplace management with the same goal of profitability. Use this list to determine if an agency has the right talent, data, services, and accountability to drive full Amazon growth, not just ad performance.

This guide is for U.S. brands that already sell on Amazon.com. You can use it before talking to an agency, when looking over a proposal or renewal, or when thinking about a new partner. It helps you compare agencies with real evidence, not just a polished sales pitch.

Quick Decision Snapshot: What a Strong Amazon Marketing Agency Should Prove

A confident agency would tell you straight up what it owns, what data it utilizes, how it makes decisions, and who holds responsibility post the sales call. If you don’t have those answers clearly defined before you sign, you may not have them after you onboard.

What an Amazon Marketing Agency Should Actually Manage

An Amazon marketing agency should manage the areas that directly affect marketplace growth. If your internal team keeps ownership of some areas, those boundaries should be clearly defined.

The agency name is less important than whether the advertising, listings, catalog, creative, reporting, and operations are all aligned to work together toward the same business objective.

For many brands, the core scope includes:

• Advertising management across Sponsored Products, Sponsored Brands, Sponsored Display, and Amazon DSP when relevant.
• Amazon SEO and listing work, including keyword coverage, indexing, detail-page quality, and conversion issues.
• Catalog and account operations, including variation problems, suppressed listings, content accuracy, and coordination between Seller Central and Vendor Central.
• Creative work for product images, A+ Content, Brand Stores, and other assets that help shoppers understand products and make buying decisions.
• Reporting that ties ad performance to total sales, organic presence, SKU velocity, inventory, and margins.
• A clear working process with owners, deadlines, escalation paths, and next steps instead of recommendations that remain in a presentation.

If you need a broader service model instead of an audit framework, review SalesDuo’s Amazon marketing agency services.

If you mainly need media execution, compare the scope with dedicated Amazon advertising management instead of assuming you need a broader marketing engagement.

If daily marketplace operations are the main problem, Amazon account management support may be a better fit.

Start With the Business Problem, Not the Agency Pitch

Choose the agency model after you define the problem you need to solve.

A brand with increasing ad spend and decreasing total sales has a different problem than a brand with healthy traffic but crappy variations, or traffic but poor product images, or traffic but constant stockouts, or traffic but no proper reporting.

If organic visibility is the main issue, ask whether the agency can connect its strategy to Amazon SEO services instead of treating keywords as the only solution.

If conversion is the main problem, ask who owns Amazon listing optimization services and how listing work connects with catalog and advertising decisions.

If images, A+ Content, or Brand Store assets are the main bottleneck, confirm whether the agency has an in-house or clearly owned Amazon creative services process.

The Amazon Agency Checklist: 12 Criteria to Score

Rate agencies on the basis of evidence, and not on the basis of how convincing their narrative sounds.

A Pass signifies that the agency has a process or deliverable. A warning means you need a better answer. A Fail is an exit or the opportunity to also narrow the scope prior to contract.

If an agency is being warned otherwise, get a specific example, the name of the person responsible, or a document before proceeding. Resolve any ambiguous account access, unsupported assurances, or absent contract protections prior to signing anything. If you are comparing agencies, consider the risks which are most important to your business, rather than just how many warnings they have gotten.

Do not simply add every score into one final “winner” number unless each criterion matters equally to your business.

A brand with a serious catalog problem may give more weight to catalog governance. A brand with a strong internal team may care more about strategy and measurement than daily execution.

Amazon Ads partner status can help you assess an agency's advertising experience, but it does not prove that the agency can manage your catalog, creative work, inventory coordination, or reporting. Use the Amazon Ads Partner Directory as one source of evidence, then check the agency's actual scope, team, and results.

How to Audit an Agency’s Reporting Sample

A useful report should explain what changed, why it changed, what the team will do next, and what the decision means for the business.

A dashboard that only shows spend, sales, and ACoS may look complete while still leaving your team to interpret the account.

Ask for a sample report and check these areas:

Sample test reporting: Pick a critical ASIN and ask the agency to show you what shifted, why it shifted, and what they recommend you do next. The response should tie ad spend, total sales, conversion, inventory, and margin where data exists. It also should clarify who owns the next action and when results will be evaluated. 

Amazon Ads defines ACoS as ad spend divided by ad revenue and ROAS as ad revenue divided by ad spend. It also says there is no single “good” ACoS for every brand. See the Amazon Ads ACoS and ROAS guide for the platform definitions.

For example, $10,000 in ad spend and $50,000 in ad-attributed revenue equals a 20% ACoS and 5.0 ROAS. If total Amazon sales are $150,000, TACoS would be 6.7% using the common agency formula of ad spend divided by total Amazon sales.

These are reporting calculations, not performance metrics that apply across the board.

TACoS helps shift the discussion beyond ad-attributed sales. But an agency should still review it alongside margin, organic sales movement, promotions, inventory, and category conditions.

If reporting is a major reason you are changing partners, review how SalesDuo presents its Amazon BI dashboard and compare that visibility with the sample reports you receive from other agencies.

Questions to Ask Before the First Call

Good questions help you understand how an agency works before you sign.

Ask each finalist the same core questions so you can compare their answers fairly.

• Which business problem do you think we should solve first, and what evidence could change that diagnosis?
• Which services are included, which are excluded, and who owns each workstream after onboarding?
• Who will work on our account after the sales call, and how many accounts does each person manage?
• What Seller Central or Vendor Central access do you need, and why is each permission required?
• Do you have a report example that ties together ads, total sales, organic movement, SKU performance, and actions?
• What advice do you have for dealing with catalog problems, suppressed listings, variation issues, and content modifications that negatively affect ad performance?
• What proof can you show from a brand with a similar category, account model, and level of complexity?
• What happens during the first 30, 60, and 90 days, and what will you need from our internal team?
• How are extra projects priced, and what work falls outside the retainer or project fee?
• What are the cancellation, handoff, data ownership, and creative-asset terms if we end the relationship?

For a broader evaluation framework, use SalesDuo’s guide on how to review an Amazon agency.

If cost becomes the main decision point, review the Amazon agency pricing guide instead of turning this checklist into a simple rate comparison.

A Practical 30/60/90-Day Accountability Map

The precise timing will depend on the account, but the agency should be capable of explaining how its diagnosis becomes actual work with clear owners. Use this table as a basis for discussion, not to dictate a particular timetable.

Contract and Operating-Cadence Checks

Before signing, confirm which services are included, who owns each workstream, and how often your team will meet with the agency. The agreement should explain response expectations, escalation procedures, extra project fees, cancellation terms, and how account data and creative assets will be handed over if the relationship ends. Ask who will actually manage the account after onboarding

‍

Red Flags That Should Stop the Process

A red flag does not simply mean the agency has a different business model. It may show that the agency cannot support the scope it is selling, measure its work clearly, or protect your control of the account.

• Guarantees sales, ranking, Buy Box wins, reinstatement, or fixed advertising efficiency without clear conditions and evidence.
• Promises to be "full service" but the service is only defined as advertising in the offer, and the rest of the catalog, creative, reporting, or account operations are not specified in the offer.
• It provides reports on activity but not decisions, owners, next steps, or SKU-level movement.
• Asks for full account access without clarifying what permissions it needs and for what purpose.
• Shares case studies but does not show the marketplace, time frame, baseline, metric definition, or what the agency controlled.
• Contains contract terms that create confusion around cancellation, asset ownership, data handoff, or additional fees.
• Uses a PPC-only diagnosis for every problem even when listings, inventory, catalog, pricing, or margin are limiting performance.

What to Prepare Before Asking for an Account Audit

A useful audit needs enough information to separate symptoms from root causes.

You do not need a large data room. Provide the agency sufficient context to get up to speed on the account and so that they can ask more informed questions.

Prepare:

• Priority ASINs and product URLs, including major variations or parent-child families.
• Recent monthly Amazon sales and ad spend, with the marketplace and time period clearly listed.
• Current advertising reports or screenshots showing major campaigns and trends.
• Approximate margin or COGS information so recommendations reflect profitability.
• Known catalog, listing, suppression, inventory, or operational issues.
• Current dashboards or weekly reports from your team or existing agency.
• Marketplace and account model: Seller Central, Vendor Central, or both.
• Your top three business goals and the main problems you want the audit to test.

Keep sensitive login details out of shared documents. Grant access only through Amazon’s current authorization and role-management methods needed for the work.

When SalesDuo May Be the Right Amazon Marketing Agency for Your Brand

SalesDuo could be right for you when your challenge spans areas, and your team wants the strategy connected to execution.

Its public service pages cover Amazon advertising, SEO, listing work, creative, account management, marketplace operations, and BI reporting. That broader organization may be helpful when one problem impacts another area of the account.

This model may be less useful if you only need one narrow specialist service and already have an internal team managing everything else.

Use the 12-point scorecard above to decide whether you need full-service support, a focused specialist, or a smaller audit before committing to ongoing work.

If your list of things to check has gaps in reporting, catalog work, creative, ad accountability, or operational ownership, escalate those gaps on the first call. Ask SalesDuo for the same proof, clear scope, team ownership, and reporting corroboration you’d ask for from any other agency.

What should I prepare before a SalesDuo growth call?

Bring priority ASINs, recent monthly Amazon sales and ad spend, current reports, marketplace details, known account issues, services you may need, and the goals you want the agency to review.

This gives the conversation enough context to focus on your account instead of generic discovery.

If your checklist shows that you need cross-functional execution rather than another isolated tactic, Book Your 1:1 Growth Call with SalesDuo.

Frequently Asked Questions about Amazon Marketing Agency

What should an Amazon marketing agency manage?

A full-service Amazon marketing agency can handle ads, SEO, listings, catalog, creative, reporting, account ops, and growth planning.

The tag is less important than the SOW (statement of work). It should be clear what the agency owns and what it leaves with you internally.

How do I evaluate an Amazon marketing agency before signing?

Use the same scorecard for every agency. Review scope, diagnosis, Amazon experience, advertising, SEO, creative, catalog governance, reporting, operations, access, proof, and contract terms.

Ask for a sample report, named account team, references, and a first-90-day plan before signing.

What should be included in an Amazon agency audit?

A useful audit needs your goals, priority ASINs, recent sales and ad spend, margin information, current reports, known catalog or inventory issues, marketplace details, and problems with your current partner.

The audit should prioritize actions instead of only listing problems.

What reporting should an Amazon ads agency provide?

Reporting should connect advertising metrics such as ACoS and ROAS with total sales, paid and organic movement, SKU-level changes, inventory or offer limits, margin context, and clear next steps.

The report should also show what the agency will do next and who owns each action.

How is an Amazon ads agency different from an Amazon marketing agency?

An Amazon ads agency mainly focuses on media planning, campaign management, optimization, and measurement.

An Amazon marketing agency may cover advertising plus SEO, listings, catalog work, creative, reporting, account operations, and broader marketplace coordination.

What are red flags when choosing an Amazon agency?

Be aware of forced results, ambiguous scope, insufficient reporting, unclear account access, no named owner, bad handoff terms, and suggestions that revolve just around ad metrics and do not consider catalog, product inventory, conversion, or margin.

Do Amazon partner badges guarantee results?

No. Amazon Ads presents partner status as one data point that can help advertisers compare providers.

You should still review business fit, scope, proof, team structure, reporting, and contract terms before choosing an agency.
