Amazon has become one of the most competitive marketplaces in the world. To win, brands need more than strong products and good reviews. They need performance advertising, data fluency, and creative that stands out in crowded categories. That is why many brands turn to specialized Amazon advertising agencies. But with so many players claiming to be the best, how do you know which partners actually deliver?

This guide breaks down how to evaluate an Amazon agency, why outsourcing often beats going in-house, and which agencies are leading the way in 2025.

How We Selected the Best Amazon Advertising Agencies

There is no single “best” Amazon ad agency. Different brands have different needs, so the right partner depends on size, category, and growth stage. Our evaluation looked at verified client results, Amazon certifications, case studies, and industry recognition. We also reviewed retention rates and breadth of services to make sure the agencies highlighted here can handle both immediate advertising needs and long-term growth.

Evaluation Criteria

When vetting agencies, four factors separate leaders from average operators:

• Proven ROAS improvements over at least three client accounts

• Deep platform expertise across PPC, DSP, and Amazon Marketing Cloud

• Client retention rates above industry average

• Service breadth that goes beyond ads to include creative, listing optimization, and reporting

Data Sources and Verification

We validated performance claims using third-party review platforms like Clutch and G2, client testimonials, and published case studies. The goal was to filter out agencies that rely on buzzwords and spotlight those with a verifiable track record.

Why Work With an Amazon Ad Agency Instead of Going In-House

Many brands wrestle with whether to build an in-house team or outsource to an agency. The decision often comes down to cost, expertise, and speed.

Cost Efficiency vs. Building a Team

Hiring in-house means salaries, benefits, software subscriptions, and training. For most mid-market brands, that adds up to more than an agency retainer. Agencies give you access to an entire team of specialists at a predictable cost.

Access to Amazon Advertising Experts and Tools

Top agencies have proprietary tools, API access, and relationships with Amazon account managers. They see algorithm changes early and adjust faster than most in-house teams.

Faster Testing and Scaling

Agencies run hundreds of campaigns across multiple categories every month. That testing volume means they know which levers to pull and how to scale spend without wasting budget.

Comparison of Core Services and Pricing Models

Agencies often look similar on the surface, but their service mix and pricing structures vary. Here is what you should expect.

PPC and DSP Management

Sponsored Products, Sponsored Brands, and Sponsored Display campaigns remain the foundation of Amazon advertising. For higher budgets, Amazon DSP allows advanced audience targeting and off-Amazon retargeting. The best agencies know when to use each and how to layer them for efficiency.

Creative and Listing Optimization

Winning on Amazon is not only about bids. A+ Content, polished photography, and well-written listings directly impact conversion. Strong agencies integrate creative services with ad strategy so traffic does not go to weak product pages.

Analytics and Reporting Dashboards

Amazon Marketing Cloud is reshaping how brands analyze performance. Agencies that provide custom dashboards with AMC data, cross-channel attribution, and profitability metrics give you an edge.

Typical Pricing Structures

Expect three common models:

• Percent of ad spend, typically 10 to 20 percent

• Flat monthly retainers, often $3,000 to $15,000 depending on scope

• Performance-based models where fees rise only if agreed metrics are hit

Project fees for creative, audits, or account setup are often billed separately.

Key Trends Shaping Amazon Advertising Success in 2025

Agencies succeeding today understand where the market is moving.

Rise of Amazon Marketing Cloud and First-Party Data

Brands increasingly rely on AMC to integrate first-party data and refine targeting. Agencies must have AMC expertise to stay competitive.

Increased Demand for Video and Sponsored TV Ads

Video formats and Sponsored TV are growing rapidly. Agencies that can produce compelling creative and optimize video placements are in demand.

AI-Driven Bid Automation

Amazon’s native tools and third-party platforms now offer automated bidding, but results vary. Agencies with proprietary AI or disciplined testing deliver better outcomes than teams that rely solely on Amazon defaults.

How to Choose the Right Amazon Ads Agency for Your Brand

Not every agency is right for every brand. The key is matching your growth stage and goals to the right partner.

Match Services to Growth Stage

Startups may need scrappy PPC support, while established brands often require DSP, international expansion, and creative integration.

Review Case Studies and Metrics

Look for case studies that show ROAS, TACoS, and revenue lift. Red flags include vague results, over-reliance on impressions, or “guaranteed” outcomes.

Assess Tech Stack and Communication

Ask about reporting frequency, dashboard access, and who on the team will manage your account day to day.

Essential Questions to Ask During Your Agency Vetting Calls

To make the right choice, ask practical questions during initial conversations:

• What contract terms and exit clauses are included?

• How often will I see reports and what metrics are tracked?

• How do you optimize for TACoS, not just ACoS?

• Who owns the data and campaigns if we leave?

• What tools and technology do you use beyond Amazon’s native suite?
