Best Amazon Advertising Agencies for $1M to $10M Brands in 2026

This guide covers the Amazon Advertising agencies that fit brands at $1M to $10M monthly. Amazon agency selection is structurally different from Google or Meta selection because the platform itself constrains what the agency can do. A great Amazon agency is a different operational profile than a great Google Ads agency, even when both run paid acquisition for DTC brands.

We evaluate every agency on the same four things: track record, operational fit, specialization depth, and transparency. Rubric and disclosures. This guide is organized by fit, not a single leaderboard. Our read on each agency reflects public information as of June 2026. One pick is a sister company of this publication's owner; that relationship is disclosed on its card and did not buy its placement.

How to use this list

Decide what kind of Amazon operation you are before you read the picks:

• Amazon is most of your business. You want a dedicated Amazon shop that lives in Sponsored ads, DSP, and catalog. The Amazon specialists below are built for you.
• Amazon is one channel of several. You also run a DTC store, Meta, Google, or TikTok Shop, and you would rather one senior team coordinate Amazon with the rest for blended efficiency than run it in a silo. The cross-channel partner below fits you.

Match your profile to the pick, then dig into its strengths and weaknesses.

Inclusion criteria

• A core focus on Amazon Advertising, or Amazon run as a managed channel inside a coordinated ecommerce practice
• Clients selling on Amazon at $1M+ monthly revenue
• Real DSP experience, or full Amazon channel management, not "we ran a small test once"
• At least 3 verifiable references, one of which is an ended engagement
• Pricing model published or shared on first call

What makes Amazon agency evaluation different

A few things change the calculus on Amazon specifically:

• TACoS over ACoS. Strong Amazon agencies talk about Total Advertising Cost of Sales, not just ACoS on ad-attributed sales. The total picture is what matters; the ad-attributed slice in isolation is gameable.
• Catalog and listing optimization. Some Amazon agencies will not touch ads without first fixing listing quality, A+ content, and brand store. Their reasoning is correct: poorly-listed products convert badly regardless of ad spend.
• Inventory and supply chain awareness. Amazon agencies who do not ask about your inventory cycle in the first meeting are agencies who will scale spend into a stockout.
• Brand registry and policy. Agencies that have managed accounts through suspensions, listing pulls, and brand registry disputes are operationally different from agencies that have not.

How to choose between these Amazon agencies

Three questions decide most of it. Answer them before you take a single sales call.

• Is Amazon the business, or a channel? If Amazon is 70 percent or more of revenue, hire a dedicated Amazon shop that lives in Sponsored ads, DSP, and catalog. If Amazon is one surface beside a DTC store and other marketplaces, a senior cross-channel partner that coordinates Amazon with the rest usually beats running it in a silo.
• Do you need catalog work, or only ads? Some accounts are held back by listing quality, A+ content, and a thin brand store, not by bid strategy. If yours is, weight the picks that fix the catalog before they touch spend. If your listings already convert, a pure PPC specialist will move faster.
• How complex is your catalog and footprint? A focused US catalog rewards a specialist. A large SKU count, international marketplaces, or a Walmart and TikTok Shop expansion rewards an agency built for breadth.

The agency that is right for a focused US PPC account is rarely the same one that is right for a 2,000-SKU cross-border catalog. Match the profile, not the logo.

What an Amazon agency costs in 2026

Most Amazon agencies in this band charge a monthly retainer, commonly low to mid four figures at the entry point and rising with spend, SKU count, and scope. A minority price as a percentage of ad spend, which rewards spending more rather than spending well, so read that model closely. DSP, catalog and creative production, and international expansion are usually scoped on top of the base retainer.

The number that matters is not the retainer. It is the retainer measured against the profit the account produces after ad cost. A higher fee that holds TACoS down while protecting margin is cheaper than a low fee that scales spend into a stockout. Ask every agency how they price, what is included, and what triggers a higher tier, then get it in writing before you sign.

Questions to settle before you choose

Does my brand actually need a DSP partner?

DSP earns its place when you have the budget for always-on retargeting and prospecting and a catalog deep enough to feed them. Below that, Sponsored Products and Sponsored Brands do most of the work and a DSP line item is mostly overhead. Ask the agency to show where DSP fits your specific account, not their deck.

Should the agency touch my listings, or only my ads?

If your conversion rate is weak, ads amplify the leak. Agencies that insist on fixing listings, images, A+ content, and the brand store before scaling spend are usually right to. If your listings already convert, that work is optional and you can hire for ads alone.

What does a good Amazon report look like?

It leads with TACoS and total profit, not ACoS in isolation. It separates branded from non-branded spend. It ties ad changes to organic rank and to inventory position. A report that shows only ad-attributed ROAS is hiding the part of the picture that decides whether the account is healthy.

How fast should I expect results?

Account structure and listing fixes show up in weeks. The compounding gains, where better rank feeds lower TACoS feeds more rank, take a quarter or two. An agency promising a transformation in 30 days is selling the 30 days, not the result.

One pick is owned by this publication's parent. Does that change the ranking?

The relationship is disclosed on that card and did not buy placement. It is scored on the same four dimensions as every other pick and sits where the rubric puts it, not at the top. Weigh the disclosure yourself.
