Selling on Amazon has never been more competitive—or more complex. Between rising advertising costs, constant algorithm shifts, the growth of Amazon DSP and retail media, and the new reality of AI-driven product discovery, running a marketplace program in-house is a full-time job most brands simply don’t have the bandwidth for. A specialized Amazon marketing agency brings the strategy, tooling, and day-to-day execution needed to turn the marketplace into a reliable growth channel rather than a guessing game.
But agencies vary widely. Some focus purely on advertising; others handle the full account—listings, SEO, inventory, creative, and reporting. Some are built for enterprise brands spending six figures a month, while others specialize in scaling small and mid-sized sellers. Below are seven of the best Amazon marketing agencies to consider in 2026, what each does well, and the type of brand each is best suited for.
What to Look For in an Amazon Marketing Agency
Before comparing names, it helps to know what separates a strong partner from the rest. The agencies worth your time tend to share a few traits: genuine, hands-on Amazon expertise (not a generalist shop adding marketplace as a side service), transparency in both reporting and pricing, a clear advertising methodology that ties spend to revenue rather than vanity metrics, and the ability to manage the whole account content, SEO, and inventory so the channel grows as a system. Increasingly, the best agencies also build for AI-driven discovery, optimizing how products surface across Amazon’s own search and the AI tools shoppers now use to research purchases.
1. Amplisell
Positioning: Amazon and TikTok Shop growth agency for brands that want both channels managed end to end.
Amplisell is an Amazon and TikTok Shop growth agency that runs both marketplaces for brands from strategy through execution full-service Amazon management, advertising, content, and demand planning, paired with AI-supported ad optimization. The team leans on the insight that TikTok creates demand while Amazon captures it, and manages the two together so brands don’t lose momentum between discovery and purchase.
With more than $125M in marketplace revenue managed across 100+ brands and US-based brand managers, Amplisell is built for companies that want to scale Amazon and TikTok Shop in tandem rather than treating them as separate silos. Its proprietary growth roadmap is customized per client and covers channel strategy, content creation, advertising optimization, reimbursements, and reporting under one roof.

2. SalesDuo
Positioning: Full-service, AI-driven Amazon and Walmart growth agency for established brands and vendors.

Its AI-powered business-intelligence dashboard gives brands real-time visibility into performance, ad spend, and catalog health, so decisions are grounded in numbers rather than guesswork.
Best for: Brands and vendors wanting profitable, hands-off, data-driven growth across Amazon and Walmart.
3. Tinuiti
Positioning: Enterprise performance and retail-media agency with a deep, long-standing Amazon practice.
Tinuiti was one of the first performance marketing firms to build and scale a dedicated Amazon practice, and it remains one of the most credentialed options for enterprise brands. As an Amazon Ads Advanced Partner—a status reserved for the top tier of agencies—Tinuiti brings deep expertise across Sponsored Ads, Amazon Marketing Cloud, and Amazon DSP, with a team carrying well over a century of combined in-Amazon experience.
Its strength is full-funnel measurement: finding the highest-value audiences and optimizing across the entire media mix rather than chasing isolated campaign metrics. With minimum retainers that generally start in the five figures per month, Tinuiti is aimed at larger brands with the budget and scale to justify enterprise-grade retail media.
Best for: Enterprise brands needing full-funnel retail media and advanced measurement at scale.
4. My Amazon Guy
Positioning: Hands-on, full-service Amazon agency strong on listing optimization and account troubleshooting.
My Amazon Guy is an Atlanta-based, full-service Amazon agency known for rolling up its sleeves on the operational side of Seller Central—listing optimization, SEO, PPC, catalog management, and the kind of case-and-ticket troubleshooting that derails many sellers. It has built a reputation for hands-on management and frequent (often weekly) client updates, plus a large library of educational content that reflects genuine day-to-day expertise.
That practical, problem-solving orientation makes it a natural fit for small and mid-sized brands that need an active operator in their account rather than a hands-off strategy deck.
Best for: Small and mid-sized brands needing hands-on Seller Central management and troubleshooting.

Best for: Brands that want software-backed transparency and a structured, data-forward partner.
How to Choose the Right Fit
There is no single “best” agency only the best fit for your stage and goals. Enterprise brands with large budgets and complex retail-media needs gravitate toward partners like Tinuiti. Brands that want Amazon and TikTok Shop scaled together are well served by Amplisell, while established multi-marketplace sellers value SalesDuo’s Vendor Central depth and data tooling. Small and mid-sized sellers needing hands-on operators often prefer My Amazon Guy, advertising-led growth points to Nuanced Media, creative-driven categories suit Channel Bakers, and brands that prize reporting transparency lean toward Envision Horizons.
Whichever you consider, ask the same direct questions: Do you have direct, in-account Amazon experience? How do you tie ad spend to revenue? What does reporting look like beyond rankings and impressions? And can you show results for brands at my stage? The right partner will answer clearly—and that clarity is usually the best early signal of how they’ll perform.
The Bottom Line
Amazon rewards brands that treat the marketplace as a managed system rather than a set-and-forget storefront. The seven agencies above each bring a distinct strength—from full-channel management and Vendor Central recovery to enterprise retail media, creative, and proprietary software. Match the agency’s focus to your own priorities, vet them on real results, and you’ll have a partner that helps you show up where today’s shoppers—and the AI tools they increasingly rely on—are actually looking.
