Best Amazon DSP Agency: How to Evaluate Partners for Full Funnel Growth

TL;DR

What to expect from this article

A practical guide to evaluating Amazon DSP agencies, covering what DSP is and when it fits, how to judge a partner on attribution, audience strategy, creative, and full funnel execution, the questions to ask, the red flags to avoid, and the agencies commonly researched. It closes with realistic cost and results expectations.

Key takeaways

DSP rewards retail readiness first. Catalog health, stable inventory, and a mature Sponsored Ads program matter more than budget size when deciding whether DSP is worth it.

Attribution and audience strategy separate strong agencies. The best partners show incremental measurement and full funnel audience planning, not last click ROAS alone.

Coordination beats isolation. DSP performs best when it is integrated with Sponsored Ads, catalog, and organic growth under one coordinated operating model.

Intro

Looking for the best Amazon DSP agency? Amazon DSP has evolved far beyond a simple display advertising channel. Brands now use Amazon DSP to run full funnel advertising across streaming TV, Prime Video ads, display inventory, and off Amazon inventory powered by Amazon audiences and retail data. At the same time, Amazon’s retail media ecosystem is becoming one of the largest advertising environments in the market.

That growth creates opportunity, but it also creates waste. We regularly see brands spend heavily on DSP campaigns that drive impressions but fail to improve TACoS, attract profitable new to brand customers, or support long term organic growth.

Weak reporting, poor attribution visibility, disconnected Sponsored Products campaigns, and retail readiness issues often undermine otherwise promising media strategies.

The best Amazon DSP agency is not the agency with the flashiest pitch deck or the biggest client logos. It is the partner that connects Amazon media buying with operational execution, transparent measurement, and profitable customer acquisition.

In this guide, we’ll walk through how ecommerce brands should evaluate DSP partners using practical business criteria like NTB acquisition efficiency, attribution transparency, AMC capabilities, retail readiness, and full funnel integration.

What is Amazon DSP and when does it make sense for brands?

Amazon DSP is Amazon’s programmatic advertising platform that allows brands to buy display, video, audio, streaming TV, and Prime Video ads across Amazon owned properties and off Amazon inventory. Unlike Sponsored Products or Sponsored Brands, DSP campaigns are audience driven rather than keyword driven. Brands can target Amazon audiences based on shopping behavior, purchase history, lifestyle signals, and in market intent.

The platform operates through programmatic advertising auctions, where advertisers bid on impressions in real time across websites, apps, streaming TV placements, Twitch, IMDb, and Amazon properties. Amazon explains that DSP campaigns can run both on Amazon owned inventory and third party inventory using Amazon’s first party shopper data. That data advantage is the main reason DSP has become a major retail media channel.

DSP usually makes the most sense once brands move beyond pure bottom funnel acquisition. Sponsored Products and Sponsored Brands are excellent for capturing existing demand, but they have limits. If your catalog already converts well and your Sponsored Ads campaigns are stable, DSP can help expand reach, improve new customer acquisition, and build repeat purchase behavior.

Streaming TV and Prime Video inventory have also changed how brands approach upper funnel growth. According to Amazon Ads, Prime Video ads now give advertisers access to premium streaming inventory tied to Amazon measurement and audience targeting capabilities.

For most brands, the right approach is not DSP versus Amazon Sponsored Display or Sponsored Products. It is coordinated full funnel advertising where Sponsored Ads capture high intent traffic while DSP expands audience reach and nurtures future demand.

Why brands hire an Amazon DSP agency instead of managing in house

Managing Amazon DSP well requires far more than basic campaign setup. Brands often hire an Amazon DSP agency because DSP management combines media buying, audience strategy, Amazon Marketing Cloud analysis, creative testing, attribution modeling, and retail operations.

AMC has become one of the biggest dividing lines between average agencies and advanced operators. Amazon Marketing Cloud is a privacy safe clean room environment that allows advertisers to analyze pseudonymized campaign data and build advanced audience insights. Agencies with strong AMC capabilities can measure incrementality, evaluate cross channel paths to purchase, and identify profitable NTB acquisition opportunities.

Most internal ecommerce teams simply do not have the staffing depth to manage DSP at the cadence it requires. Sponsored Products optimization already consumes significant operational bandwidth. Adding streaming TV, audience segmentation, campaign pacing reviews, creative refreshes, and AMC reporting often overwhelms lean in house teams.

Strong agencies also connect DSP management to retail readiness. They understand that campaign optimization means little if listings convert poorly, inventory goes out of stock, or Brand Store experiences break the customer journey. The best Amazon advertising agency partners treat DSP as part of a larger retail growth system rather than a siloed media channel.

How to evaluate the best Amazon DSP agency

The best Amazon DSP agency should be evaluated on business outcomes, not marketing language. We recommend assessing agencies using five core areas: retail readiness, NTB acquisition efficiency, attribution transparency, full funnel audience execution, and operational integration.

A strong Amazon DSP partner should explain how their strategy improves TACoS, supports customer acquisition, and contributes to profitable growth over time. Agencies focused only on ROAS often optimize toward easy retargeting conversions instead of incremental revenue.

Buyers should also verify whether agencies hold Amazon Ads certifications, use AMC actively, and provide transparent reporting access. Amazon’s own partner ecosystem requires agencies to demonstrate technical competency and certified expertise.

Most importantly, ask how the agency coordinates DSP with Sponsored Products, Sponsored Brands, Amazon SEO, inventory forecasting, and conversion rate optimization. DSP campaigns amplify retail fundamentals. They rarely fix weak ones.

Retail readiness and catalog health

Catalog health directly impacts DSP performance. Even excellent audience targeting will struggle if listings have weak images, inconsistent pricing, poor reviews, low inventory levels, or underdeveloped Amazon Brand Store experiences.

The best agencies connect Amazon listing optimization with media buying. They review conversion infrastructure before aggressively scaling DSP spend. That includes inventory management, parent child variation structure, Brand Store quality, review velocity, and mobile conversion experience.

Retail readiness also affects retargeting efficiency. If product detail pages fail to convert traffic from Sponsored Display or DSP campaigns, brands end up paying repeatedly to reacquire the same users. Agencies that understand conversion rate optimization often produce stronger TACoS outcomes over time because they improve both paid and organic performance.

New to brand (NTB) acquisition efficiency

The strongest DSP agencies prioritize new to brand growth rather than maximizing short term ROAS alone. Amazon defines new to brand metrics as purchases from customers who have not bought from a brand during a defined lookback period.

NTB metrics help brands understand whether campaigns are driving customer acquisition or simply retargeting existing shoppers. Agencies should evaluate NTB rates alongside TACoS, incrementality, customer acquisition cost, and lifetime value potential.

ROAS and ACoS still matter, but they can become misleading if agencies optimize only for low funnel retargeting. In many cases, higher funnel DSP campaigns intentionally accept lower immediate efficiency to generate stronger future demand and improved organic ranking.

Advanced agencies often use AMC to evaluate audience overlap, incrementality, and exposure sequencing. That allows them to identify which audiences produce genuinely incremental customer acquisition.

Attribution transparency and reporting

Transparent DSP reporting should go far beyond top level ROAS dashboards. Brands should expect visibility into audience level performance, campaign pacing, view through attribution, frequency exposure, creative performance, and halo effects across the catalog.

View through attribution matters especially for streaming TV and display campaigns because many users convert after seeing an ad without clicking it. Strong agencies explain attribution windows clearly and separate assisted conversions from direct click based conversions.

The best DSP reporting environments combine Amazon analytics dashboards, unified reporting, and AMC analysis. Brands should understand which audiences drive incremental lift, how Sponsored Ads interact with DSP exposure, and where campaign spend contributes to long term retail growth.

If an agency refuses to share granular reporting access or only provides monthly summary PDFs, that is usually a warning sign.

Audience strategy and full funnel execution

Top agencies structure DSP campaigns around the customer journey. That means separating prospecting campaigns, retargeting pools, loyalty audiences, and streaming TV initiatives instead of lumping all spend into one blended strategy.

Prospecting campaigns usually target in market Amazon audiences and category shoppers. Retargeting campaigns focus on users who viewed products or engaged with Sponsored Ads. Loyalty campaigns reconnect with repeat customers and subscribers using AMC driven segmentation.

Frequency capping is another critical operational layer. Amazon defines frequency capping as controlling how often a user sees an ad during a specific time period. Strong agencies actively manage frequency exposure to avoid wasted impressions and creative fatigue.

Streaming TV has also become central to modern full funnel strategy. Prime Video ads and OTT advertising now allow brands to build awareness while still connecting campaigns to measurable retail outcomes.

Creative and video capabilities

Creative quality has an outsized impact on DSP success. Display creative, OTT advertising assets, Prime Video inventory, and Amazon video ads all influence engagement rates, detail page visits, and conversion performance.

Strong agencies maintain active creative testing workflows. They rotate messaging, refresh assets regularly, and test different video formats against audience segments. DSP campaigns often fail because brands reuse static creative for months while frequency exposure climbs.

Video has become especially important across Amazon’s advertising ecosystem. Amazon case studies have shown improved click through and detail page performance when brands use coordinated video creative across full funnel campaigns.

Operationally, agencies should also manage asset specifications, creative approvals, Brand Store alignment, and refresh cycles. Good DSP media buying without creative iteration rarely scales efficiently.

Integration with Sponsored Ads and organic growth

The most effective agencies integrate DSP with Sponsored Products, Sponsored Brands, Sponsored Display, Amazon SEO, and organic ranking initiatives.

DSP creates demand higher in the funnel, while Sponsored Ads often capture conversion ready traffic lower in the funnel. When these systems operate independently, brands lose efficiency and duplicate audience exposure.

Integrated agencies use DSP to improve branded search demand, reinforce product launches, and support keyword ranking growth. They also coordinate inventory forecasting and retail operations so DSP traffic does not push users toward out of stock ASINs.

TACoS becomes especially useful here because it reflects how paid advertising impacts total revenue growth, not just ad attributed conversions.

Questions to ask before hiring an Amazon DSP agency

Discovery calls reveal far more than agency websites. The goal is to understand how a partner thinks, measures success, and communicates.

Ask agencies how they structure DSP strategy, how often they optimize campaigns, what level of AMC access they provide, and how they coordinate with retail operations. You should also ask for reporting examples, testing frameworks, and explanations of how they evaluate incrementality.

The best Amazon advertising partners answer these questions clearly and operationally. Weak agencies usually default to vague statements about scaling impressions or maximizing ROAS.

How do you measure incremental growth from DSP campaigns?

Agencies should explain how they validate incrementality rather than relying only on attributed conversions. Strong partners use AMC reporting, holdout testing, NTB analysis, and audience comparison models to evaluate true demand generation.

Incrementality testing compares exposed audiences against control groups to estimate how many conversions DSP campaigns genuinely caused. Agencies using AMC can analyze cross channel exposure paths and compare audience lift over time.

If an agency cannot explain how they separate incremental growth from retargeted demand, measurement sophistication is probably limited.

What reporting access will we receive?

Professional DSP partners should provide dashboard access, campaign pacing visibility, audience level reporting, and regular strategic reviews.

At minimum, brands should expect access to spend pacing, audience performance, placement reporting, creative metrics, NTB data, and attribution insights. Many advanced agencies also provide Looker Studio dashboards or AMC based reporting environments.

Limited visibility usually creates accountability problems later.

How do you coordinate DSP with Sponsored Ads and retail operations?

Strong agencies align DSP management with inventory forecasting, Sponsored Display campaigns, PPC management, and catalog operations.

Ask how they handle out of stock suppression, ASIN prioritization, Brand Store coordination, and keyword alignment across Sponsored Products and DSP campaigns. Coordination matters because media buying alone cannot overcome operational friction.

What optimization cadence and testing process do you follow?

Good DSP management follows a repeatable optimization cadence. Agencies should conduct daily pacing checks, weekly audience and bid reviews, and monthly strategic testing analysis.

Ask how they approach A/B testing, creative iteration, audience expansion, budget pacing, and frequency management. Strong agencies can explain exactly what gets reviewed at each stage and how decisions are documented.

A vague answer usually means optimization is reactive rather than systematic.

Common red flags when comparing Amazon DSP agencies

Several warning signs appear repeatedly when brands compare Amazon DSP agencies.

The first is vague reporting. If an agency cannot explain audience level performance, NTB metrics, view through attribution, or AMC workflows, measurement maturity is likely weak.

The second is overreliance on ROAS. DSP campaigns influence awareness, consideration, and repeat purchase behavior across longer attribution windows. Agencies obsessed with short term ROAS often avoid the upper funnel tactics that support long term growth.

Another red flag is lack of retail operations understanding. DSP performance depends heavily on catalog health, inventory stability, pricing competitiveness, and Brand Store quality.

Finally, be cautious of agencies positioning themselves as generic full service marketers without clear Amazon native operational depth.

Types of Amazon DSP agencies and which one fits your brand

Amazon DSP agencies generally fall into four categories.

Enterprise retail media agencies typically support large omnichannel brands with complex organizational structures and multi retailer media strategies. Amazon native agencies focus more deeply on marketplace operations, TACoS management, and Seller Central execution. Performance marketing firms often emphasize media buying efficiency and attribution systems. Software enabled agencies combine managed services with automation platforms and AI driven optimization.

The right fit depends on your stage, internal resources, and operational complexity. A mid market Amazon native brand may benefit more from a retail operations focused agency than from a large enterprise consultancy. Conversely, national omnichannel brands often require cross retailer reporting, advanced analytics infrastructure, and broader retail media coordination.

Top Amazon DSP agencies to research

There is no universal best Amazon DSP agency for every brand. Different partners specialize in different operating models, budgets, and organizational needs.

The agencies and platforms below are widely associated with Amazon DSP management, AMC analysis, retail media execution, and marketplace growth. The goal is not to rank winners, but to help brands identify which operating style aligns with their growth priorities.

Kyzenn

Kyzenn is a boutique Amazon growth agency that runs DSP as one part of a connected operating model rather than an isolated media buy. Advertising sits alongside catalog health, listing quality, external traffic, and promotions, so audience and bidding decisions stay tied to profitability and inventory position.

Kyzenn reports around contribution margin and TACoS rather than isolated ROAS, and coordinates DSP with Sponsored Ads and organic growth under one team. It suits established brands that want full funnel execution and direct operator level attention rather than layered account hierarchies.

Canopy Management

Canopy Management positions itself as an Amazon growth partner focused on PPC, DSP, and operational transparency. The agency emphasizes TACoS management, profitability tracking, and integrated Amazon PPC execution.

Canopy also highlights DSP management services tied to broader marketplace operations rather than isolated media buying.

Flywheel Digital

Flywheel Digital is heavily focused on enterprise retail media and omnichannel commerce. Its positioning centers on large scale marketplace management, retail analytics, and integrated media operations across major retailers.

The company’s Flywheel Commerce Cloud infrastructure supports enterprise level reporting and omnichannel advertising execution.

Tinuiti

Tinuiti operates as a large independent performance marketing agency with extensive ecommerce media capabilities. The agency supports enterprise Amazon advertising, AMC strategy, streaming TV, and cross channel media planning.

Tinuiti is also recognized as an Amazon Ads Advanced Partner.

Incrementum Digital

Incrementum Digital is known for profitability focused Amazon advertising management. The agency frequently emphasizes TACoS growth, operational efficiency, and integrated marketplace execution.

Its positioning appeals strongly to growth oriented Amazon brands seeking profit conscious scaling.

Nuanced Media

Nuanced Media positions itself as an Amazon focused growth and advertising agency with omnichannel ecommerce capabilities. The agency combines advertising management with broader marketplace consulting and operational support.

Its approach appeals to brands looking for integrated marketplace growth services rather than media buying alone.

Pacvue, Perpetua, Quartile, and Teikametrics

Pacvue, Perpetua, Quartile, and Teikametrics represent the software enabled side of Amazon advertising management.

These platforms combine automation, AI optimization, reporting infrastructure, and campaign management tools. Many brands use them internally or alongside agencies to improve bidding, pacing, and analytics visibility.

Automation can improve efficiency, especially for large scale Amazon PPC and DSP environments, but software alone rarely replaces strong strategic oversight, creative direction, and retail operations alignment.

How much does an Amazon DSP agency cost?

Amazon DSP pricing varies based on media spend, management structure, and service depth.

DSP campaigns typically run on CPM based pricing, meaning advertisers pay per thousand impressions. Costs may include Amazon platform fees, media management fees, creative production, AMC analysis, and agency retainers.

Some agencies charge percentage of spend pricing, while others use flat retainers or hybrid structures. Managed service DSP campaigns historically carried high minimums, although many agencies now support lower entry points through self service access models.

Brands should evaluate value based on operational support, measurement sophistication, retail integration, and reporting transparency rather than management fees alone.

What results should you expect from an Amazon DSP agency?

DSP performance should be evaluated over months, not days. Most campaigns require a ramp up period for audience learning, creative testing, and attribution analysis.

Brands should expect gradual improvements in NTB growth, branded search volume, audience reach, and cross channel efficiency rather than immediate bottom funnel ROAS spikes.

Attribution also becomes more complex as campaigns expand into streaming TV and upper funnel media. View through conversions, halo effects, and multi touch journeys matter significantly in DSP measurement.

Ultimately, DSP success depends heavily on retail fundamentals, operational consistency, and testing maturity.

Future trends shaping Amazon DSP management

Several trends are reshaping Amazon DSP management.

AMC adoption is accelerating as brands demand deeper attribution visibility and privacy safe audience analysis. Agencies increasingly use Amazon Marketing Cloud to connect streaming TV, Sponsored Ads, and retail analytics into unified measurement systems.

AI optimization is also becoming more prominent across bidding, pacing, audience segmentation, and creative analysis. At the same time, streaming TV advertising continues expanding rapidly through Prime Video and connected TV inventory.

We also expect tighter integration between retail media and broader programmatic advertising ecosystems. Amazon is steadily positioning DSP as a central commerce media platform rather than a standalone Amazon only advertising tool.

Conclusion

The best Amazon DSP agency is the partner that connects media buying with retail readiness, attribution clarity, and profitable customer acquisition. Strong DSP performance comes from coordinated execution across AMC analysis, audience targeting, Sponsored Ads integration, catalog health, creative testing, and operational discipline.

Brands should evaluate Amazon DSP partners based on transparency, measurement sophistication, NTB acquisition efficiency, and full funnel integration rather than surface level ROAS claims alone. Agencies that understand TACoS, incrementality, inventory management, and organic growth dynamics usually create more durable outcomes.

Before signing with any Amazon DSP agency, conduct structured discovery calls, request reporting examples, ask detailed operational questions, and evaluate how the agency connects advertising with broader ecommerce performance. That diligence usually separates profitable long term partnerships from expensive media experiments.
