Choosing an Amazon agency is not about jumping on the bandwagon, selecting the cheapest proposal, or picking the agency with the most polished sales deck. There is no single best choice for every brand.
The right agency will understand your category, interpret your growth priorities, report consistently, and connect advertising, listings, operations, customer experience, and profitability.
A strong Amazon agency should help you answer:
- What is restricting growth?
- Which levers should be the focus?
- How are we measuring performance?
- Who runs the execution and reporting?
- And what will it look like in the first 30, 60, and 90 days?
Use this guide to evaluate Amazon PPC agencies, SEO partners, DSP specialists, operations teams, and full-service Amazon agencies with a single, consistent decision framework.
An Amazon agency review should assess strategic fit, relevant proof, pricing, reporting quality, communication, and execution capabilitiesโnot simply rank providers in a โbest agenciesโ list. This article focuses on evaluating and choosing an Amazon growth agency. Companies that already understand their requirements and want to find a good Amazon agency, can check our blogs on:

Quick Answer: How Do You Choose an Amazon Agency?
Pick an Amazon agency by matching your main growth problem with the agencyโs Amazon-specific expertise, category experience, proof, reporting quality, pricing model, communication style, and execution capabilities.
The best Amazon marketing partner should understand how these areas work together:
- Amazon PPC
- Amazon SEO
- Listing optimization
- Seller Central and/or Vendor Central operations
- Account health
- Amazon DSP
- Reporting and BI dashboards
- ACoS, TACoS, ROAS, and total sales
Do not choose based only on reviews, awards, or โtop agencyโ lists. Those can help create a shortlist, but they do not prove fit.
The better question is: Which agency is best for our current Amazon growth problem?
Before hiring an agency: Evaluate whether your inventory, margins, pricing, product quality, or production capabilities can absorb the additional volume. Advertising can only help if you are not failing elsewhere in your operations (product or pricing).
Step 1: Define Your Amazon Growth Goal
Before comparing agencies, define what you need the agency to fix. Agency fit depends on the problem you are solving.
| Goal | Best Agency Fit | Key Question |
|---|---|---|
| Lower ACoS | Amazon PPC agency | Can they show ACoS and TACoS improvement? |
| Improve conversion | Amazon Listing optimization agency | Can they show before/after listing results? |
| Scale full account | Full-service Amazon agency | Can they manage ads, SEO, content, ops, and reporting? |
| Grow awareness | DSP or media agency | Can they prove audience and funnel strategy? |
| Fix account issues | Seller/Vendor Central expert | Can they handle compliance and operations? |
| Improve organic visibility | Amazon SEO agency | Can they improve keyword rank and listing relevance? |
Start by identifying the bottleneck. Unless you have a product page issue, simply managing your ads more efficiently will not bring you significant improvements. If your ad campaigns are chaotic, a creative agency can hardly fix them on its own.
A competent agency should first define the problem before attempting to sell an expensive solution.
Step 2: Understand the Difference between Types of Amazon Agencies
The term โAmazon review agencyโ can have two meanings. It may refer to an agency being reviewed as a potential Amazon growth partner, or to a provider that manages product reviews, customer feedback, and reputation workflows.
This guide focuses on evaluating agencies that manage growth on the Amazon marketplace. Product review and reputation management providers should be assessed as a separate service category.
Amazon PPC / Advertising Agencies
Amazon PPC agencies are typically responsible for Sponsored Products, Sponsored Brands, Sponsored Display, bidding, budgeting, keyword selection, and campaign structure. Your brand may also want to consult the Amazon Ads Partners Directory to find agencies that specialize in PPC management. If you find a reputed agency in the directory, do not assume they are the best fit for your brand, category, or account, but consider them as one of your options.
Choose this type if your main problem is wasted spend, high ACoS, poor structure, or underperforming ads.
Amazon SEO and Listing Optimization Agencies
Amazon SEO and listing agencies improve titles, bullet points, images, A+ Content, Storefronts, keyword relevance, and conversion rates.
This approach is most relevant when CTR is high, but sales are lowโads are generating clicks, but shoppers are not converting.
Full-Service Amazon Agencies
Full-service Amazon agencies manage ads, SEO, listings, account health, reporting, catalog issues, and operations.
Choose this type if your Amazon growth problem touches several areas at once.
Amazon DSP and Retail Media Specialists
Amazon DSP and retail media specialists focus on audience strategy, retargeting, upper-funnel media, and full-funnel measurement.
Choose this type if your brand has enough budget and wants to grow beyond search-based demand.
Account Health and Operations Agencies
These agencies help with suppressions, catalog cleanup, chargebacks, shortage claims, compliance, and Seller/Vendor Central issues.
Choose this type if operational problems are blocking sales.
Product Review and Reputation Specialists
These providers focus on compliant review generation, customer feedback, reputation monitoring, and review-related workflows. They should not be confused with Amazon advertising or full-service marketplace agencies.
Choose this type only when product feedback and reputation management are the primary need. Confirm that every process follows Amazonโs review and communication policies.
Step 3: Use an Amazon Agency Evaluation Scorecard
The best way to evaluate Amazon agencies is to score each option against the same criteria. This keeps the decision objective and helps your team compare agencies fairly.
Score each agency from 1 to 5 for every criterion. Then apply the weight based on importance.
| Evaluation Criterion | Weight | What to Check | Strong signal | Warning sign |
|---|---|---|---|---|
| Amazon expertise | 20% | PPC, DSP, SEO, Seller Central, Vendor Central, catalog, and compliance | Connects ads, listings, pricing, inventory, and account health | Uses generic ecommerce tactics or focuses only on ad spend |
| Category experience | 15% | Product knowledge, margins, competition, seasonality, and customer behavior | Shares relevant examples and understands category challenges | Uses the same strategy for every category |
| Case studies | 15% | Baselines, actions, timelines, results, and business impact | Provides measurable results with clear context | Makes vague claims or shares unexplained screenshots |
| Reporting quality | 15% | ACoS, TACoS, ROAS, CVR, rankings, sales, and profitability | Explains what changed, why, and what happens next | Reports numbers without insights or actions |
| Technology | 15% | Automation, dashboards, alerts, integrations, and data ownership | Uses technology to support faster, better human decisions | Relies entirely on automation or cannot explain its tools |
| Strategic fit | 10% | Whether the plan addresses your main growth problems | Prioritizes key issues in a logical order | Recommends a standard package before reviewing the account |
| Communication | 5% | Strategist access, meetings, response times, and escalation | Clearly defines who owns strategy, execution, and updates | Roles are unclear, or access is limited after the sale |
| Pricing transparency | 5% | Scope, fees, exclusions, ownership, add-ons, and contract terms | Clearly explains deliverables, fees, and extra costs | Hides exclusions, add-ons, or termination conditions |
Quick takeaway: Choose the agency that best matches your current Amazon growth problemโnot simply the one with the highest overall score. Adjust the weights based on your category, account size, and service needs.
A high score does not necessarily indicate a universally better option; rather, it indicates what is more relevant to you. You can change the criteria weights to reflect that category expertise, operations, creative, and tech stack are more or less important to your specific account needs. โTechnology and dashboards
Step 4: Check Amazon-Specific Expertise
Amazon is not the same as Shopify, Google Ads, Meta, or a regular retail website. The platform has its own ranking signals, ad formats, catalog rules, policies, reporting limits, and operational issues.
Check whether the agency understands:
- Seller Central and Vendor Central
- Amazon DSP
- Amazon SEO
- Listing conversion
- Sponsored Products, Sponsored Brands, and Sponsored Display
- Brand Registry
- Account health
- Retail readiness
- Inventory and Buy Box impact
- Relevant Amazon Ads certifications for the team members who will work on the account
- ACoS, TACoS, ROAS, and organic rank
- Search term reports and campaign structure
Certifications can support technical credibility, but they should not replace category experience, case-study evidence, transparent reporting, or a clear account strategy. A strong Amazon agency should explain how all these contribute to the overall results. If they focus only on ad spend or only on creatives, they may miss out on the bigger picture.
Step 5: Review Proof and Category Experience
A good Amazon agency should be able to provide concrete evidence, not vague promises. The best case studies include the problems, baseline performance figures, the approach, timing, actions, their impact, and the overall effect on the business.
Ask about case studies featuring companies similar to yours. The category in which a brand operates is vital in determining the effectiveness of Amazon services. Different products, pricing, margins, review counts, and competition require unique approaches.
What Strong Proof Includes
Look for:
- Original challenge
- Baseline metrics
- Timeline
- Strategy used
- Actions taken
- Results
- Business impact
- Category context
What Weak Proof Looks Like
Be careful with:
- โWe grew salesโ with no number.
- No timeline
- No category context
- No baseline
- No clear strategy
- Screenshots without analysis
A strong agency should explain what changed, why it changed, and how it was measured.
Step 6: Evaluate Reporting and Data Transparency
Good reporting should show what happened, why it happened, and what the agency will do next. A dashboard alone is not enough.
| Metric | Why It Matters |
|---|---|
| ACoS | Measures ad efficiency |
| TACoS | Shows ad impact on total sales |
| ROAS | Shows how much income is earned for every dollar spent on paid ads |
| Conversion rate | Shows listing and traffic quality |
| CTR | Shows ad relevance |
| Organic rank | Shows long-term search impact |
| Share of voice | Shows category visibility |
| New-to-brand sales | Shows customer acquisition |
| Total sales | Shows business growth |
| Margin impact | Shows profitability |
Ask for a sample report before signing. The report should be easy to understand and tied to actions.
A weak agency reports numbers. A strong agency explains decisions.
Step 7: Compare Pricing Models and ROI
Amazon agency pricing should be evaluated based on the complete scope of work, account complexity, team involvement, creative requirements, marketplace coverage, technology access, and expected business value.
A lower monthly fee is not automatically the less expensive option. Important services may be excluded, limited to a fixed number of ASINs, or billed separately.
| Pricing Model | Best For | Usually includes | What to watch for |
|---|---|---|---|
| Flat retainer | Brands with a predictable monthly scope | Strategy, execution, meetings and reporting | Work outside the agreed scope may cost extra |
| % of ad spend | Advertising-heavy accounts | PPC management tied to media spend | The model may reward higher spend rather than greater efficiency |
| Performance-based | Brands with clearly defined outcomes | Fees connected to agreed revenue or performance targets | Attribution, baselines and external variables must be defined carefully |
| Hybrid | Brands seeking shared risk and incentives | Base retainer plus spend-based or performance-based fees | Complex terms can make the final cost difficult to predict |
| Project-based | Audits, launches, listing projects, or Store builds | Defined deliverables within a fixed timeline | Ongoing monitoring and optimization are usually excluded |
Before comparing proposals, confirm whether the fee includes:
- Strategy and account audits
- Sponsored Ads and DSP management
- Amazon SEO and listing optimization
- Creative production and revision rounds
- Storefront or A+ Content work
- Seller Central or Vendor Central support
- Reporting and dashboard access
- Marketplace expansion
- Meetings and strategist access
- Technology fees
- Travel, media, or third-party costs
- Implementation after the initial audit
Also inquire about the required ad spend, contract duration, onboarding fees, possible performance bonuses, number of revisions, any extra costs for travel or third-party hiring, and any additional ASINs or marketplaces.
In addition, the most significant criterion will not be the monthly cost but the overall scope of work, the organizationโs efforts and expenses, the contract details, and whether it addresses your issues appropriately.
Step 8: Ask These Questions on the Discovery Call
The discovery call is not just what they sell. It should also tell you how the agency thinks.
Ask:
- Have you worked with brands in our category?
- Do you manage Seller Central, Vendor Central, or both?
- What do the first 30, 60, and 90 days look like?
- What reports will we receive?
- Who owns campaign setup and execution, and who manages the data?
- How do you correlate ACoS with TACoS?
- How often do we speak with the strategist?
- Who will actually manage the account?
- Do we retain full ownership of our Amazon accounts, data, listings, and assets?
- How do you handle listings, inventory, and account-health issues?
- What happens if performance drops?
- What happens to our data and access if the partnership ends?
- Who will own strategy, execution, and reporting?
- Will you provide handover documentation and exportable reports?
- Are there notice periods, termination fees, or offboarding requirements?
- Which tasks are included in the fee?
Listen for clear, specific answers. If the agency cannot explain how it would manage your account, it may not be ready to foster your growth.
Step 9: Watch for Amazon Agency Red Flags
Avoid agencies that make big promises without showing the process behind them. Amazon growth is complex, so simple guarantees are usually a warning sign.
Key red flags that may indicate that your potential agency partner is not worth your precious time (and budget) include:
- promises of specific rank or revenue,
- focus solely on ACoS with no regard to TACoS or overall revenue,
- inability to explain the nuances of campaign structure,
- avoidance of showing reporting examples,
- reliance on automation only,
- absence of category-specific examples,
- continual pressure to increase ad budgets with disregard to listing optimization,
- failure to distinguish between account ownership and management,
- inability to provide specific figures on the cost or, conversely, hidden additional fees,
- no account health review process,
- and failure to explain the expectations for the first 90 days.
The right agency should be clear about what it can control, what it cannot control, and what needs to happen next.
Step 10: When Should You Hire a Full-Service Amazon Agency?
Hire a full-service Amazon agency when growth depends on multiple areas. Since ads, listings, SEO, reporting, catalog issues, and account health are all connected, a single-channel partner may not always be enough.
Evaluate whether the agency can identify cross-channel problems, prioritize the correct growth levers, and coordinate Amazon PPC, DSP, SEO, listing optimization, account health, operations, and reporting. The right full-service partner should explain how its services work together to improve ACoS, TACoS, conversion, organic visibility, total sales, and profitability.
Readers who have already defined their requirements and want to compare potential providers can review our comparison of the best Amazon agencies.
A full-service agency may be the right fit if:
- Ads are spending, but listings are not converting.
- ACoS looks fine, but TACoS is not improving.
- Account issues are blocking sales.
- Organic ranking is weak.
- Campaign reporting is unclear.
- Growth requires ads, content, operations, and analytics together.
The goal is not to hire more services. The goal is to fix the whole growth system.
When You May Not Be Ready to Hire
A full-service agency may be unnecessary when your problem is limited to a single, clearly defined area and your internal team can manage the rest of the work.
A specialist or project-based partner may be more suitable when:
- PPC efficiency is your only immediate issue.
- You need a one-time listing or creative refresh.
- Your team already manages operations and reporting.
- You need help with a specific catalog or compliance issue.
- Your revenue does not support a full-service engagement.
- Your product, inventory, pricing, or margins are not growth-ready.
Choose the narrowest service model that can solve the actual problem. Hiring more services than you need can increase costs without improving outcomes.
Advantages and Disadvantages of Hiring an Amazon Agency
Hiring an Amazon agency can provide expertise and execution capacity, but it also adds cost and requires close coordination. Evaluate both sides before signing.
| Advantages | Disadvantages |
|---|---|
| Access to Amazon specialists | Monthly or performance-based fees |
| Faster execution across channels | Time needed for onboarding and approvals |
| More structured reporting | Possible dependency on an outside team |
| Experience across categories and accounts | Quality varies significantly by agency |
| Access to tools, dashboards, and processes | Poor contracts can restrict data or asset ownership |
| Additional capacity without hiring a full internal team | Results still depend on product, margin, inventory, and market conditions |

Ask about category experience, Seller/Vendor Central knowledge, reports, ownership, pricing, team structure, 90-day plan, and how they measure ACoS, TACoS, and total sales.
When should I hire an Amazon agency?
Hire an Amazon agency when limited internal expertise, execution capacity, or reporting visibility is slowing growth. An agency is particularly useful when several connected issuesโsuch as advertising, listings, organic visibility, catalog operations, account health, or analyticsโneed coordinated support. A specialist may be sufficient when the problem is limited to a single, clearly defined area.
Should I hire an Amazon PPC agency or a full-service Amazon agency?

The main advantages include access to Amazon specialists, faster execution, additional capacity, structured reporting, and coordinated support across advertising, SEO, listings, operations, and analytics. Potential disadvantages include agency fees, onboarding time, dependence on an external team, and inconsistent service quality. Hiring an agency makes sense when its strategic and operational value exceeds its cost and the internal effort required to manage the partnership.

Red flags include guaranteed rankings, vague pricing, no case studies or reporting samples, an automation-only service, weak Amazon-specific expertise, and poor communication.
What should happen in the first 90 days?
The first 90 days should include an account audit, goal alignment, campaign and listing reviews, reporting setup, quick fixes, a testing plan, and a growth roadmap.
