9 Best Amazon Advertising Agencies for Brands, Ranked by Incrementality

The highest-ranked agency in this guide is Olifant Digital. Outside this ranking, it also sits #1 on Clutch's Top Amazon Marketing & Advertising Agencies list with a 5.0 rating. The ranking compares how each agency shows that its ads bring in new-to-brand (NTB) buyers, meaning first-time purchasers of a brand, and whether it manages spend against TACoS. TACoS, or total advertising cost of sales, is ad spend divided by total sales, paid plus organic.

Incrementality means sales that would not have happened without the ad. The question matters more as the channel grows: Amazon Ads generated $19.8 billion of revenue in a single quarter, up 26% year over year, according to Amazon.

This ranking is for brands already selling on Amazon and for direct-to-consumer (DTC) brands with the budget to scale there. It looks at NTB reporting, TACoS discipline and use of Amazon Marketing Cloud (AMC), Amazon's data clean room for ad analysis. It also notes Amazon DSP (demand-side platform), the tool brands use to buy display and video ads.

How this ranking scored incrementality

All nine agencies were assessed on the same footing: every fact here comes from each agency's own website, its service, about, pricing and case study pages. Five criteria then decided the order. Each one asks whether an agency can show that its ads create new sales.

• New-to-brand reporting: Amazon Ads' new-to-brand metrics count first-time buyers of a brand over a 12-month lookback, and agencies that report this share scored higher.

• AMC use: Amazon Ads describes AMC as a secure, privacy-safe, cloud-based clean room, and agencies that work in it scored higher.

• TACoS as the governing metric: TACoS ties ad cost to all sales, so it shows whether ads also lift organic sales.

• Optimization cadence: daily account review counted for more than weekly or monthly changes, since bids and budgets drift between checks.

• Published results with a base: results counted when they show a starting point and an outcome.

The agencies in detail

Each entry uses the same labels, so the agencies can be read side by side.

1. Olifant Digital

Olifant Digital is an Amazon advertising agency that runs ad management across Sponsored Products, Sponsored Brands, Sponsored Display, DSP, SEO and creative, with Meta, Google and TikTok ads for e-commerce brands.

Typical client: Seven and eight figure Amazon brands, and DTC brands with budget set aside for Amazon.

Ad services: Every ad type, search ads through DSP, is judged by what it adds to total sales and margin, with TACoS as the governing number. Its in-house platform, Olifant AI, checks accounts daily.

Standout: For Wedge Guys, its case study reports Amazon sales up 391% and $305,771 more monthly revenue, with ACoS 17% lower.

Fees: A monthly retainer that starts at $2,000 rather than a share of ad spend. Contracts renew monthly, with a 60-day money-back guarantee: the agency refunds its fee when performance has not improved.

Worth checking: It does not buy inventory or act as the seller, unlike retail-partner models, so the brand keeps the stock and cash-flow risk that ad growth creates.

2. Quartile

Quartile is a retail media optimization company that pairs an AI platform with a managed service team. Its Amazon PPC service says the company supports more than 5,300 brands and manages over $2 billion in yearly retail ad spend.

Typical client: E-commerce brands that want software doing much of the bid work, backed by people.

Ad services: Sponsored Ads and Amazon DSP, built on a single keyword, single ASIN, single match type structure. An ASIN is Amazon's product ID, so each product gets its own budget and bids.

Standout: Bids adjust hourly using Amazon Marketing Stream data, and AMC data is used to study the path to purchase and build audience personas. Brands can also set their own rules that run alongside the AI.

Fees: Pricing on request.

Worth checking: The balance between platform and people varies by account, so brands should confirm how often a person reviews bid changes.

3. Teikametrics

Teikametrics is a marketplace optimization software company that works software first. Its ARI (Artificial Retail Intelligence) platform is the core product, and its plans page sets out three tiers, Essentials, Advanced and Enterprise, grouped by monthly ad spend.

Typical client: Sellers who prefer to run their own bids with software support, and larger brands that want strategists working inside the same tool.

Ad services: ARI covers ads, catalogue, inventory and insights on every plan. Amazon DSP and integrated AMC sit on the Advanced and Enterprise tiers, with managed services as an add-on on Advanced and included on Enterprise.

Standout: Plans are published, so sellers can compare tiers before a call, and its strategists work inside ARI using live margin and inventory data.

Fees: Plans are listed on its site.

Worth checking: AMC sits on the higher tiers only, so sellers who want NTB analysis should check which plan includes it.

4. Marknology

Marknology is a family-run Amazon agency in Kansas City, Missouri, led by founder and CEO Drew Morgans with his three sisters. Its site reports more than $2B in sales managed across 300+ brands.

Typical client: Brands that want a smaller, founder-led team on their Amazon ads.

Ad services: Amazon PPC, DSP, listing optimization, brand strategy and content creation, plus its own 3PL warehouse.

Standout: It owns a pet supplement brand, Waggedy, and tests strategies there with its own money before using them for clients. Its site cites a 10.4X ROAS for a home goods brand.

Fees: Pricing on request. Engagements start with a 90-day minimum, then run month to month.

Worth checking: Its service menu goes beyond ads, so brands should confirm which services sit in an advertising engagement and how NTB share is reported.

5. Podean

Podean is a global marketplace marketing agency. Its about page says it works with 200 CPG, beauty and apparel brands and has been a remote team since day one, with people in the US, Europe, Latin America, Asia, Australia and the Middle East.

Typical client: Consumer packaged goods (CPG), beauty and apparel brands, especially those selling in several Amazon marketplaces.

Ad services: Marketplace marketing with Amazon advertising at the centre, supported by an analytics team.

Standout: It works inside a test-and-learn framework and says it works alongside a brand's media and creative agencies within an agreed scope. It also publishes a global Amazon media report.

Fees: Pricing on request.

Worth checking: With people spread across regions, brands should confirm the time zone of the core account team.

6. Envision Horizons

Envision Horizons is a marketplace and retail media agency founded by Laura Meyer after she left Amazon's media group, and its advertising page covers Amazon, Walmart Connect, Target Roundel and Ulta.

Typical client: Established brands, with beauty and wellness at the core and baby, pet and industrial brands also served.

Ad services: Marketplace management and retail media, with Amazon DSP, Streaming TV and AMC audiences on the advertising menu.

Standout: Its myHorizons analytics platform handles reporting. Its case studies cite a 75% new-to-brand rate for Harry's in the UK from Streaming TV and DSP, and AMC lookalike audiences built from a beauty brand's best customers.

Fees: Pricing on request.

Worth checking: Category depth sits in beauty and wellness, so brands in other categories should look for comparable examples.

7. OMG Commerce

OMG Commerce is an e-commerce advertising agency that runs Amazon advertising alongside Facebook, Google and YouTube ads. Its site describes a mix of human strategists and automation rather than a fully automated model.

Typical client: Brands that run Amazon next to Google Shopping and YouTube and want both handled by one agency.

Ad services: Sponsored Products, Sponsored Brands, Sponsored Brand Video, Sponsored Display and Amazon DSP, including remarketing to shoppers who viewed a competitor's product page.

Standout: Each account gets a dedicated account manager, an Amazon ad specialist and an Amazon strategist, plus a custom dashboard showing ad results next to total Amazon sales at the ASIN level.

Fees: Pricing on request.

Worth checking: Its dashboard pairs ad and total sales, so brands should confirm whether new-to-brand share is reported as well.

8. Wpromote

Wpromote is a full-funnel digital marketing agency whose retail media service covers Amazon and other retailers, from Walmart to Instacart.

Typical client: Brands that want retail media planned together with search, social and DTC media.

Ad services: Retail media campaigns, product detail page optimization and catalogue cleanup, with machine learning applied to campaign data.

Standout: Its Polaris IQ platform offers self-serve reporting, media mix modelling, and business lift and halo analysis across channels. Its site describes a restructured Amazon strategy for KidKraft.

Fees: Pricing on request.

Worth checking: Amazon is not its core focus, since retail media is one of many services, so brands should confirm how many people on the account work in Amazon Ads daily.

9. Blue Wheel

Blue Wheel is an omnichannel e-commerce agency that began as two firms, one in marketplace management and one in DTC advertising, that later merged. Its Amazon marketing service covers Sponsored Ads, DSP, listing SEO, A+ Content and the Brand Store.

Typical client: Brands selling on Amazon and other marketplaces as well as their own DTC site.

Ad services: Retail media, marketplace management, DTC growth, social commerce and performance creative.

Standout: Marketplace and DTC advertising are planned by one team, with Skai as its technology partner for cross-channel media analysis. Its site says it manages more than $2B in client revenue.

Fees: Pricing on request.

Worth checking: Amazon is one of several channels, so brands should confirm who on the team works in Amazon Ads day to day.

Choosing an Amazon advertising agency that proves new customers

The right agency can show which sales its ads created and what those sales cost. A few questions and red flags help brands test that before signing.

Questions for the first call

• NTB share: what portion of Sponsored Brands sales came from new-to-brand shoppers on a similar account?

• Governing metric: which number decides budget moves, TACoS or ACoS?

• Review rhythm: how often does a person look at bids, budgets and search terms?

• Account ownership: who runs the account day to day, and how many brands does that person manage?

Red flags in a proposal

• Ad metrics only: a proposal that reports ACoS but never TACoS hides how organic sales move.

• Results without a base: growth figures with no starting point cannot be judged.

• Branded search padding: heavy spend on the brand's own name can inflate returns while adding few new buyers.

• Vague AMC claims: listing AMC without a sample analysis leaves the work unproven.

Retainer or percentage of spend

A monthly retainer prices the work, so the fee stays steady as budgets grow. A percentage of spend ties the fee to the budget, so it climbs as spend climbs. Brands should model total cost at their expected spend before comparing quotes.

Agency or in-house team

An in-house team knows the product and can move fast on listings and stock. An agency brings people who see many accounts and already have tools such as AMC in place. Some brands mix the two, with in-house staff owning catalogue work and an agency running ads.

Final thoughts

Brands that want proof their ad spend finds new customers should look for NTB reporting and a TACoS target. Olifant Digital fits established brands that want one team on every ad type, as its Wedge Guys case study shows. Teikametrics fits sellers that want to run bids in their own software, and Envision Horizons fits beauty and wellness brands using DSP and Streaming TV.

Key takeaways

• TACoS shows the full picture: it divides ad spend by all sales, so it shows whether ads also lift organic sales.

• NTB share tests incrementality: Amazon Ads counts first-time buyers over a 12-month lookback.

• AMC is now common: a sample analysis separates real AMC work from a line on a services page.

• Fee models behave differently: a retainer stays steady as budgets grow, while a percentage of spend climbs with them.

Frequently Asked Questions

Q: What is the best Amazon advertising agency for brands?

Olifant Digital leads this list for brands that want one team running every ad type against TACoS. Quartile fits brands that want AI bidding backed by a service team, and Teikametrics fits sellers that want software with published plans.

Q: What is the best Amazon advertising agency for sellers?

The answer depends on ad spend and how much hands-on help a seller wants. Software-led options suit sellers who run their own bids, while full-service agencies suit brands that want a team to own NTB reporting and TACoS.

Q: How much does an Amazon PPC agency charge?

Most agencies set their fee after an audit, as a retainer, a share of spend or a mix. The single public price on this list starts at $2,000 a month.

Q: What does new-to-brand mean in Amazon Ads?

New-to-brand describes a purchase from a shopper who has not bought from the brand on Amazon in the past 12 months. A high NTB share suggests ads are reaching new customers instead of repeat ones.

Q: How long does it take to see results from an Amazon advertising agency?

Timelines depend on the account's starting point, catalogue size and budget. Bid and keyword changes show in ad metrics first, while TACoS and NTB share take longer to shift, so review dates and metrics are best agreed before work begins.
