8 Best Performance Max Agencies for Ecommerce in 2026: Who Actually Keeps Up With Google

Choosing a Performance Max agency in 2026 is harder than it looks. Performance Max keeps changing: Google has added search terms and channel-level reporting, brand exclusions, and audience exclusions and budget reporting, so approaches that worked at launch may now underperform.

Because PMax evolves so quickly, many teams struggle to manage it, see unstable results, and switch it off. That is usually a mistake: for most online stores, PMax is still one of the most powerful ways to reach buyers across Search, Shopping, and YouTube from a single campaign.

The better move is to work with a PMax agency that keeps up with Google Ads changes and measures success by revenue, profit, and new customers, not just ROAS. Below are the best Performance Max agencies that can make your campaigns more effective and profitable.

Quick Answer: The Top Performance Max Agencies in 2026

In short: the best Performance Max agencies for ecommerce in 2026 are Promodo, Tinuiti, Smarter Ecommerce (smec), Wpromote, Logical Position, JumpFly, Inflow, and Disruptive Advertising. Promodo is the strongest fit for mid-market and large online stores that want PMax structured around margin and product priorities; Tinuiti and smec suit enterprise and large-catalog retailers; JumpFly and Logical Position suit smaller stores.

Top Performance Max Agencies for Ecommerce: Detailed Reviews

There is no single best Performance Max agency for every store. The right choice depends on your catalog size, budget, markets, and how much strategic input you expect. Here is how each team on our list approaches PMax.

1. Promodo

‍

‍

‍

Promodo is a performance marketing agency that has been helping ecommerce businesses grow since 2004, with offices in the US, the UK, and Europe. It has been a Google Premier Partner since 2016 and was a finalist in the Google Premier Partner Awards two years in a row (2022 and 2023).

How Promodo approaches Performance Max. Promodo treats PMax as a campaign type that needs regular structural review rather than a one-time setup. Instead of grouping campaigns by category by default, the team segments products by business logic — performance tiers, margin, and price — and uses search terms reporting, negative keyword lists, brand exclusions, and channel reporting to check what PMax is actually buying. Results are evaluated against revenue, profit, and category-level sales. Learn more about Promodo's Google Ads and Performance Max services.

Technology. Promodo builds its own tools for ecommerce advertisers: Feed Optimizer for product feed improvements, AdsHub for automated product labeling, and G-MOS for generating campaigns in large, fast-changing catalogs. For PMax, where feed quality decides which products get visibility, this is a practical advantage.

Proof points:

• Toy retailer (Budynok Igrashok): products were split into ABC-XYZ performance tiers with separate PMax budgets, low-visibility "zombie" products moved into their own campaigns automatically, PMax was limited to Shopping inventory, and the feed was enriched with new attributes. Over April–December 2025, core-tier revenue grew 52% while spend fell 22%, and ROAS rose 95%.
  ‍

‍

• Eldorado (electronics retailer): an early move from Smart Shopping to Performance Max with one asset group per product group and custom audience signals delivered +57.87% revenue in the first month at a similar budget.
  ‍

‍

• Varlė (Lithuanian marketplace): where Shopping ads were restricted, PMax ran without a product feed and became the account's lowest-CPA campaign; over nine months, non-brand revenue grew more than 1,000%.
  ‍

‍

• Best for: mid-market and large online stores, retailers with big or fast-changing catalogs, and brands selling in several markets.

2. Tinuiti

‍

‍

Tinuiti describes itself as the largest independent performance marketing agency in the US. It has held Google Premier Partner status every year since the program launched in 2013 and works across Google, Amazon, Meta, and retail media networks.

How Tinuiti approaches Performance Max. For large brands, PMax rarely lives in isolation — it competes for budget with Amazon, retail media, and social. Tinuiti's strength is planning Google Shopping and PMax as part of a wider commerce media mix, supported by in-house analytics and feed management.

• Best for: enterprise and omnichannel brands, especially those selling on Amazon alongside their own store.

3. Smarter Ecommerce (smec)

‍

‍

Smarter Ecommerce, based in Linz, Austria, has been working with retailers since 2007 and combines proprietary software with managed services. It is less a classic full-service agency and more a technology-led Performance Max partner.

How smec approaches Performance Max. smec is one of the most visible researchers of PMax in the industry: its "State of Performance Max 2025" analysis drew on more than 4,000 campaigns, and the team regularly publishes free scripts, including a PMax channel report script. Its Campaign Orchestrator segments products by business metrics such as value, margin, and stock. Published case studies with brands like Myprotein and Decathlon Austria focus on regaining control when PMax over-concentrated spend on top sellers. smec was also a 2025 Google Ads Impact Award finalist in the International Growth category.

• Best for: large-catalog retailers and brands running Google Ads across many markets.

4. Wpromote

‍

‍

Wpromote is a US performance marketing agency and Google Premier Partner that won the Google Premier Partner Award for Online Sales in 2021. It also sits on Google's Brand and Performance councils, which gives the team an early view of product changes.

How Wpromote approaches Performance Max. Wpromote uses PMax as one part of a wider paid search and shopping strategy. One of its published retail examples, for REEF, used Performance Max to reach new audiences and drive incremental growth rather than simply re-capture existing demand.

• Best for: mid-market to enterprise retail and DTC brands that want PMax tied into broader search, social, and creative work.

5. Logical Position

‍

‍

‍

Logical Position, headquartered in Lake Oswego, Oregon, is a Google Premier Partner and Microsoft Elite Channel Partner serving thousands of clients across North America. It won a Google Premier Partner Award in 2018 and has a large ecommerce practice.

How Logical Position approaches Performance Max. The agency combines Google Shopping, PMax, and data feed management, and gives clients a shared dashboard across paid platforms. Its scale makes it a practical choice for growing stores that want a structured, process-driven team.

• Best for: small and mid-sized ecommerce businesses looking for an established PPC partner.

6. JumpFly

‍

‍

‍

JumpFly, founded in 2003 and based in Hoffman Estates, Illinois, is one of the longest-running dedicated paid search teams in the US. It is a Google Premier Partner and holds a 4.9 rating on Clutch.

How JumpFly approaches Performance Max. JumpFly is search- and shopping-first. The team publicly walked clients through using PMax search term data and campaign-level negative keywords as soon as they became available, and in 2025 hosted an executive summit with Google covering Performance Max, AI Max for Search, and Demand Gen.

• Best for: SMB and mid-market online stores that want hands-on PPC specialists rather than a full-service agency.

7. Inflow

‍

‍

‍

Inflow, based in Tampa, Florida, is an ecommerce-focused marketing agency offering PPC, SEO, and conversion rate optimization.

How Inflow approaches Performance Max. Rather than defaulting to PMax for everything, Inflow builds a personalized mix of Standard Shopping and Performance Max campaigns, supported by continuous feed optimization. It has also shared case studies on using PMax and other automation to grow ecommerce revenue.

• Best for: mid-market ecommerce brands with established product catalogs.

8. Disruptive Advertising

‍

‍

Disruptive Advertising, based in Pleasant Grove, Utah, is a Google Premier Partner that got early access to Performance Max during its beta and has been testing it with clients since.

How Disruptive approaches Performance Max. The agency combines Google Shopping and feed management with an in-house creative team that produces ad assets and landing pages — useful for PMax, where creative quality affects reach across YouTube, Display, and Discover.

• Best for: ecommerce brands with sizable budgets that want paid media and creative production under one roof.

What to Consider When Choosing a Performance Max Agency for Ecommerce

Use these points to compare agencies — including the ones on this list.

1. Recent changes, not just years of experience. Ask what has changed in how they manage PMax over the last 12 months. A strong PMax agency names specific features and what they did with them.
2. Business metrics beyond Google Ads ROAS. Good ecommerce PMax management is measured by revenue confirmed in GA4 or your backend, profit or margin, new customer acquisition, and sales by product group.

‍

3. Brand vs. non-brand split. The agency should show how much of the PMax result comes from branded searches and returning customers — and how they control it.

‍

What we see in Promodo accounts: in ecommerce accounts we take over, a noticeable share of Performance Max conversions often comes from branded searches until brand exclusions and negative keyword lists are in place — which makes in-platform ROAS look better than the real incremental result. Segmentation pays off too: when we split a toy retailer’s catalog into performance tiers with separate PMax budgets, core-tier ROAS rose 95% while spend fell 22%

‍

4. Campaign structure with business logic. Look for segmentation by margin, performance tier, price, or new vs. returning customers, not one campaign for the whole catalog by default.
5. Use of the new controls. Search terms reporting, negative keyword lists, brand exclusions, channel performance data, and audience exclusions should be part of regular optimization, not something the team "plans to try."

6. Testing discipline. Ask how they test structure, assets, and bidding changes, and how long a test runs before they draw conclusions.
7. Feed and creative ownership. Product data and assets are among the biggest PMax levers. Make sure someone is responsible for both.
8. Transparent reporting. Channel and search term data should appear in reports and strategy discussions, not stay hidden in the account.
9. Credentials as a baseline. Google Premier Partner status is a common filter when looking for a Google Performance Max agency, but it is not proof of results on its own.
10. Red flags. Calling PMax "a black box with nothing to control," pitching the same structure to every client, and reporting only in-platform ROAS are all signs the approach has not kept up.

FAQ

[[FAQ-START]]

What does a Google Ads Performance Max agency do?

A Google Ads Performance Max agency plans, launches, and manages PMax campaigns: it sets up conversion tracking and goals, prepares the product feed and creative assets, builds the campaign structure, configures audience signals and exclusions, and optimizes based on search term, channel, and asset data. For ecommerce, a good agency also connects PMax results to revenue, profit, and product-level sales.

Is Performance Max worth it for ecommerce?

For most online stores with a solid product feed and reliable conversion tracking, yes — PMax gives access to all of Google's inventory from one campaign. But "worth it" depends on how it is managed. Without brand controls, sensible segmentation, and business-level measurement, PMax can look profitable in Google Ads while adding less incremental revenue than it appears.

Can you add negative keywords to Performance Max campaigns?

Yes. Performance Max now supports campaign-level negative keywords (up to 10,000 per campaign), shared negative keyword lists, and account-level negatives, alongside brand exclusions. The search terms report shows which queries triggered your ads, so negatives can be based on real data. See Google's Performance Max overview for the full list of campaign settings.

Should you run Performance Max or Standard Shopping?

It is rarely either/or. Many ecommerce accounts use PMax for broad reach and Standard Shopping for products or categories that need tighter control. The right split depends on catalog size, margins, and how much data each product group generates.

How much does a Performance Max agency cost?

Pricing models vary: a percentage of ad spend, a flat monthly retainer, or a hybrid with a minimum fee. Larger agencies often set minimum budgets. When comparing offers, look at what is included — feed management, creative production, analytics, and structured testing can matter more than the fee itself.
