How to Choose the Right Amazon Agency for Your Business

If you want to hire the right Amazon agency, focus on the essentials.

Look for a team with proven experience managing Amazon Seller Central and Vendor Central accounts, knowledge of your product category, Amazon Advertising certifications, the right tools like Helium 10 or Jungle Scout, clear processes, and real results shown in case studies or client reviews.

Ask direct questions about how they manage Amazon PPC, optimize listings, and improve organic rankings and Buy Box percentage.

Check their pricing model, whether it is a monthly retainer, a sales commission, or a hybrid. Make sure they track meaningful metrics such as conversion rate, ACoS, TACoS, sales growth, and account health.

Amazon has more than 9.7 million registered sellers and over 2 million active sellers. Competition is high, ad costs keep rising, and policies can change at any time. Even a small compliance mistake can lead to listing removal or account suspension.

The right agency can help you grow faster and avoid costly mistakes. Marketplace Pulse reports that brands working with experienced Amazon agencies can see sales grow by 20 to 40 percent in their first year.

Choosing the wrong agency can waste your budget, hurt your rankings, and slow your growth.

In this guide, we explain how to find a reliable Amazon agency, the questions to ask before you hire, how to compare their value, and the performance metrics you should monitor once you start working together.

Why Choosing the Right Amazon Agency Matters

Your Amazon agency is not just a vendor; it becomes a core part of your growth strategy. A skilled partner can:

• Increase your product visibility in crowded categories
• Optimize your listings for higher conversion rates
• Reduce wasted ad spend and improve ACoS and TACoS
• Maintain account health and protect against policy violations
• Identify new revenue opportunities, such as international marketplaces or emerging product trends.

A bad choice can have the opposite effect, leading to missed opportunities, lost Buy Box share, and compliance issues that can suspend your account.

Key Factors When Choosing an Amazon Agency

1. Proven Amazon Marketplace Experience

An agency should have Amazon-specific experience, not just general e-commerce knowledge.

Managing an Amazon account is very different from running a Shopify store or an eBay shop. It requires expertise in Amazon’s ranking algorithms, product listing policies, and advertising platform.

Look for an agency with:

• 3–5+ years working exclusively on Amazon Seller Central and Vendor Central accounts
• Experience handling FBA (Fulfillment by Amazon) and FBM (Fulfillment by Merchant) operations
• A portfolio of results showing growth in organic rankings, Buy Box percentage, and sales revenue
• Case studies that clearly document improvements in ACoS (Advertising Cost of Sales), TACoS (Total Advertising Cost of Sales), and conversion rates

For example, a strong case study might show how the agency reduced ACoS from 35% to 18% while increasing monthly sales from $50,000 to $85,000 in a competitive category.

2. Specialization in Your Product Category

Amazon agencies often perform better when they have niche or category expertise. The way you market and optimize listings for dietary supplements is very different from how you approach electronics or apparel.

Category-specific knowledge helps with:

• Keyword research that targets buyer intent for your niche
• Understanding category-specific compliance and policy requirements (for example, FDA labeling for supplements or voltage standards for electronics)
• Using Enhanced Brand Content (A+ Content) or Amazon Stores tailored to the buying habits in your category
• Navigating seasonal trends and high-demand sales periods, such as holiday shopping for toys or Q4 fashion spikes

If you plan to expand into international Amazon marketplaces (like Amazon UK, Germany, UAE, or Japan), your agency should understand local consumer behavior, tax compliance, shipping regulations, and competition levels in each region.

3. Certified and Skilled Team Members

Behind every strong agency is a skilled team. You need professionals who are trained in Amazon PPC (Pay-Per-Click) advertising, product listing optimization, inventory management, and account health maintenance.

Look for:

• Amazon Advertising Certifications to confirm PPC expertise
• Membership in the Amazon Service Provider Network (SPN) for verified credibility
• Partnerships with tools like Helium 10, Jungle Scout, Pacvue, or DataHawk to improve keyword targeting, bid automation, and analytics
• Specialists in key areas: Amazon SEO, product photography, copywriting, and catalog management

Ask how many accounts each account manager handles. If they are overloaded, your account will not get the attention it deserves.

4. Access to Advanced Tools and Reporting

A professional Amazon agency should use data-driven tools to guide its decisions.
These tools help identify profitable keywords, optimize pricing, improve rankings, and manage inventory efficiently.

Important tools and capabilities include:

• Keyword research and rank tracking (Helium 10, MerchantWords, DataHawk)
• Automated repricing software to stay competitive without sacrificing margins
• Listing optimization platforms to improve product titles, bullet points, and descriptions for both SEO and conversion rate
• Custom analytics dashboards so you can view performance data in real time

Reporting should be clear, transparent, and actionable, covering:

• Sales performance trends
• Advertising metrics (ACoS, TACoS, impressions, click-through rate, conversion rate)
• Organic ranking improvements for target keywords
• Buy Box win rate and account health indicators

5. Transparent Processes and Communication

Transparency is a sign of a trustworthy agency. You should know:

• What actions are they taking on your listings and campaigns
• Why are they making changes, and how does it impact your goals
• When will updates be delivered, and how often will you receive reports

A good Amazon account management agency will provide:

• Weekly or bi-weekly calls or updates
• Detailed monthly reports that explain results, not just list numbers
• Access to performance dashboards and advertising accounts so you can verify data

Clear communication prevents misunderstandings and ensures the agency’s strategy aligns with your sales targets, ROI goals, and brand guidelines.

6. Proof Through Case Studies and Client References

Any agency can make promises. Only real results prove they can deliver.

Ask for:

• Case studies that include measurable outcomes like sales growth, ACoS reduction, or improved conversion rate
• Client testimonials from sellers in similar industries
• Direct references so you can speak to current or past clients about their experience

Look for metrics that show consistent improvement over time, not just short-term spikes.
For example, sustaining a TACoS under 10% while growing revenue is a sign of long-term success, not just temporary gains.

Key Questions to Ask Before You Hire

Before you commit to working with an Amazon agency, ask questions that reveal how they work, how they measure success, and whether they are the right fit for your business.

• How do you define account success? Look for answers that focus on metrics like conversion rate, ACoS, TACoS, sales growth, and Buy Box percentage, not just “more sales.”
• Can you share results from similar accounts? Ask for anonymized case studies or examples from brands in your category.
• Who will manage my account? Find out if you will have a dedicated account manager or if your account will be passed around between multiple people.
• Is your work done in-house or outsourced? In-house teams usually provide more consistent communication and quality control.
• What is your pricing structure? Make sure you understand if they charge a monthly retainer, sales commission, or a hybrid model, and if there are any setup fees.
• Do you follow Amazon-approved strategies? Avoid agencies that take shortcuts or use risky tactics that could lead to listing suppression or account suspension.
• How often will I get updates? Regular communication, such as weekly or bi-weekly reports, is important to keep you informed.

Understanding Pricing, Contracts, and Value

Amazon agencies can price their services in different ways.

The most common models include:

• Retainer: A fixed monthly fee that gives you predictable costs and a set scope of services.
• Commission: A percentage of sales, often tied to performance, but can become costly as revenue grows.
• Hybrid: A mix of a base fee plus a commission, offering stability with a performance incentive.

When reviewing a contract, make sure it clearly outlines:

• The specific deliverables and services included
• Performance benchmarks or targets
• Contract length and exit terms in case you’re not satisfied

Do not just compare costs; compare the value and ROI. 

A more expensive agency that consistently increases profit margins can be worth far more than a cheaper agency that delivers little to no growth.

How to Vet and Shortlist Agencies

Once you’ve identified potential agencies, do your due diligence before making a decision.

• Check verified directories, like the Amazon Service Provider Network, Clutch, and Trustpilot, for reviews and ratings.
• Look at client feedback, on LinkedIn, case studies, and testimonials to see if their clients are satisfied long-term.
• Watch for red flags, such as vague answers, lack of transparency, or unrealistic promises like “guaranteed top rankings in two weeks.”
• Evaluate their onboarding process: strong agencies start with a detailed audit of your account, competitor research, keyword analysis, and a tailored strategy.
• Consider cultural fit: agencies that understand your brand voice, values, and target market will be easier to work with.

Tracking and Measuring Agency Performance

Hiring an agency is only the first step. You also need to monitor their work to ensure it delivers the results you expect.

Key metrics to track include:

• Conversion rate: Shows how well listings turn clicks into sales.
• ACoS and TACoS: Indicates advertising efficiency and overall ad spend impact on revenue.
• Sales growth rate: Measures month-over-month or year-over-year revenue increases.
• Buy Box win rate: Critical for visibility and sales opportunities.
• Account health score: Ensures you are meeting Amazon’s performance standards.

A good agency will be proactive in making adjustments based on performance data, seasonal trends, and competitive changes.

If results plateau, communication slows, or strategies feel outdated, it may be time to re-evaluate the partnership.

Frequently Asked Questions

How do I know if an Amazon agency is right for my business?

A good Amazon agency should have proven experience managing Amazon Seller Central or Vendor Central accounts, a track record in your product category, and positive client testimonials. Ask for case studies with real performance metrics like sales growth, ACoS reduction, and Buy Box improvements.

How much does it cost to hire an Amazon agency?

Costs vary based on services and pricing models. Common options include a monthly retainer, a commission on sales, or a hybrid of both. On average, monthly retainers range from $1,000 to $5,000, while commission-based models typically take 10% to 30% of sales managed. The key is to compare the expected return on investment, not just the price.

How long does it take to see results with an Amazon agency?

Most sellers see early improvements within 1–3 months, especially in areas like listing quality and PPC performance. Significant growth in rankings and sales usually takes consistent work over 3–6 months.

What’s the difference between Amazon agencies and general marketing agencies?

Amazon agencies specialize in the Amazon marketplace, including PPC campaigns, product listing optimization, keyword research, and account health management. General marketing agencies may focus on broader digital marketing and often lack deep Amazon-specific expertise.

Can an Amazon agency help with both PPC and organic rankings?

Yes. A strong agency will manage Amazon PPC campaigns while also improving organic rankings through listing optimization, keyword targeting, and A+ Content. The two work best when combined.

What if an agency doesn’t work out after signing?

Review the contract terms before signing. Look for short initial commitments or clear exit clauses. If performance or communication is poor, you should be able to switch without long delays or heavy penalties.

How do I verify agency claims and case studies?

Ask for detailed case studies with metrics, timelines, and clear actions taken. Request direct references so you can speak with past or current clients. Check independent review platforms like Clutch, Trustpilot, or the Amazon Service Provider Network.

Will I still have control over my Amazon account if I hire an agency?

Yes. You keep full ownership and access to your account. The agency should work as a partner, sharing reports, updates, and recommendations while you approve major changes.
