Best Google Shopping Agency: 8 Real Options Compared (2026)

Every Google Shopping agency pitch sounds the same. Certified partner. Data-driven. Proven results. A wall of logos. By the second call you cannot tell them apart, which is exactly how the weak ones survive.

So this guide does two things the pitches will not. First, it gives you six checks you can run on any agency in about five minutes each - before a single sales call. Second, it names seven real agencies, including us, and says plainly who each one fits and who should skip it. Every fact about a competitor below comes from their own site, with the date we checked it.

The Six Checks: Run Them Before Any Sales Call

Google Shopping is different from Search. In Search, the agency writes the ads. In Shopping, Google writes the ad from your product feed - title, image, price, pulled straight from Merchant Center. So the agency's real job sits upstream of the campaign, and every check below points at the same place: show me the feed work.

Run these six checks on every agency on your shortlist. Each one takes about five minutes.

1. Feed receipts. Ask: "Show me title rewrites you shipped recently, and the search-term data behind them." Titles carry most of the matching signal between products and searches. A strong agency pulls search-term reports, finds the queries that convert, and rewrites titles around them - with before-and-after examples. The weak answer is "we optimize titles as part of our feed process." No examples means the titles are whatever the store exported. The feed optimization guide shows what real title work looks like.

2. A disapproval clock. Ask: "My top product gets disapproved Friday at 5pm. What happens, and when is it live again?" Disapprovals are the most common emergency in Shopping - shipping mismatches, missing GTINs, wrong categories. Each one silently pulls products out of the auction. A strong answer has hours in it. "We monitor the account closely" is not an answer - monitoring is noticing, you asked about fixing.

3. Custom labels by margin. Ask: "How do you use custom labels to bid by margin?" Smart Bidding cannot read margin from your catalog. Without custom labels, your 60%-margin hero and your 20%-margin accessory get the same treatment. A strong agency tiers SKUs by margin and velocity and points campaigns at them with different targets. A blank look, or "we let the algorithm handle that," is a fail.

4. Pricing you can read before the call. Search the agency's site for a number. If there is no number anywhere, you learn the price on their terms, mid-pitch, after the anchoring. Of the seven agencies below, only two publish one. That alone tells you something.

5. Public reviews under the real company name. Search Trustpilot and Clutch for the agency's name. Count the reviews you can actually read. Named, public, third-party reviews are the one proof an agency cannot write for itself.

6. Exit terms. Ask for the cancellation clause before the proposal. Month to month means the agency has to re-earn the fee every month. A 6-month lock-in means they collected the pressure up front.

Tinuiti: The Enterprise Pick

Tinuiti is, by its own site, the largest independent full-funnel marketing agency in the US: 1,000+ employee owners, $4 billion in digital media under management, and 15+ service lines from linear TV to Amazon to paid search. Their case studies carry names like DSW, e.l.f., Sony, and Carter's. Checked 17 July 2026.

Who should pick them: a national or enterprise brand buying TV, retail media, Amazon, and search from one partner. Scale like theirs buys platform relationships no boutique will ever have. If that is your size, call them and go with our blessing.

What the six checks find: no pricing, minimums, or contract terms are published anywhere on tinuiti.com - those come on a sales call. Their contact form's annual spend dropdown starts at Under $1 Million, which frames who the shop is built for. Whether a 6-7 figure/month store gets their A-team, and what that costs, is a question their site does not answer.

ZenoX Media: The Feed-First Google Shopping Specialist

This is us, so apply the same skepticism you would to anyone else on this list. The checkable facts: 200+ ecom brands on Google Ads across the US, Europe, and Dubai, over 200 Merchant Centers rebuilt since 2024, over €200M in client revenue generated, and a team of 19 named people on the about page. Reviews: 4.8 from 38 reviews on Trustpilot, under our real name.

Who should pick us: a 6-7 figure/month ecom store where Google Shopping and PMax drive most of the revenue. That is the whole company - one channel, one store type. The Google Shopping management service is feed-first by design: title rewrites against your real search terms ship in week one (top 80 SKUs), custom labels tier your SKUs by margin, and our disapproval process runs six built-in fix strategies and clears most disapprovals inside 24 hours.

The checks, on us: pricing is published on the pricing page - a tiered percentage of monthly Google Ads spend, 10% on the first €10k stepping down to 6% above €150k, each rate applying only inside its own bracket. No setup fee. Month to month. Feed engineering included, not sold as an add-on.

Who should skip us: enterprise brands that want TV and Amazon in the same room (Tinuiti), suspended accounts that need rescue surgery first (More Than Scaling), and anyone under roughly €5k/month in spend - more on that below.

OuterBox: Shopping Plus SEO under One Roof

OuterBox has run ecommerce marketing since 2004, and their Google Shopping page - checked 2 August 2026 - lists the right things by name: "Data and Product Feed Optimization," "Merchant Center Setup and Compliance," "Product Title and Description Optimization." They are a Google Premier Partner, and their site cites a 4.8/5 average from 867 reviews on FeaturedCustomers and Clutch. Their in-house team spans paid media, SEO, CRO, analytics, design, and development.

Who should pick them: a US ecom brand that wants Shopping, SEO, and site work handled by one agency. Their own page says they suit "eCommerce brands with large catalogs, changing inventory, seasonal promotions, margin differences, or messy product data" - a fair description of who benefits from real feed work.

What the six checks find: the service list names feed and Merchant Center work explicitly, which most generalist pages never do. No pricing or minimums are published on the Shopping page, so check four falls to the sales call. Ask them the disapproval-clock question directly - the page describes monitoring and reporting, and you want to hear hours.

Vysta: Measurement-First for 8 and 9-Figure Brands

Vysta (Vysta Paid Media Group) is a genuine Google and YouTube ecom specialist - the closest positioning to ours in this list. Checked 17 July 2026: they state a client floor of 7-9 figure revenue and $3K+/month spend, exclude dropshipping outright, and their homepage says most clients invest £1,500-£4,000 a month in management. Their materials name serious measurement practices: geo holdouts, conversion lift studies.

Who should pick them: an 8 or 9-figure brand that wants measurement rigor most agencies never attempt. Publishing who they will NOT take - no sub-$3K spend, no dropshipping - is how a real specialist operates, and the stated fee range is more than most agencies put in writing.

What the six checks find: at our check date their Clutch profile showed zero reviews and we could not find a Trustpilot profile, and the testimonials on their site name people but not companies. No contract or cancellation terms are published. The measurement vocabulary is real - ask them the feed-receipts question, since their public materials lead with measurement rather than feed work.

More Than Scaling: The Suspension Specialists

More Than Scaling's genuine niche is the emergency this guide keeps warning about: Google Ads and Merchant Center suspension and unban work. By their own site (checked 17 July 2026): 150+ brands scaled, no long-term contracts, and a service list that spans Google, Amazon, email, funnels, and creative under one vendor.

Who should pick them: a store whose Merchant Center is suspended right now. That is specialist surgery, and they have made it a named service line rather than a thing they figure out on your account. Also a fit if you want many channels from one small vendor.

What the six checks find: no pricing published, and all six case studies on their case-studies page are anonymized - no named clients to call. Their "no long-term contracts" claim is their own wording and easy to verify in the agreement before you sign. If your account is healthy and you want month-after-month Shopping growth, the fit case is weaker than the rescue case.

groas: The Flat-Fee AI Option under $25k Spend

groas sells a hybrid: autonomous machine-learning agents running Google Ads, plus one dedicated account manager per account. The refreshing part, checked 22 July 2026: pricing is on the site - $1,499/month flat for up to $25,000/month in ad spend, no setup fees, no lock-ins. They claim $100M+ managed on Google per year for 500+ businesses and agencies, and their own posts say plainly what they do not do: no Meta, no TikTok, and agencies keep the edge on creative and multi-channel work.

Who should pick them: a store spending under $25k/month. At that level a flat $1,499 beats almost any percentage fee, and the AI-first bet is cheap to test. Their transparency - published price, admitted limits - deserves real credit.

What the six checks find: at check time we found one review on G2 and no Trustpilot or Capterra profile, so the public-review check comes up thin. And run the custom-labels and disapproval-clock questions hard: an autonomous system is only as good as its answer to "what happens when my products go down on a Friday."

Trilogi: The Builder for EU Stores and China Launches

Trilogi (TLG Commerce) is a Spain-based ecommerce agency founded in 1999 - by its own words, exclusively dedicated to building and running online stores. Google Ads is one of 15+ service lines, and they are a genuine Google Ads Premier Partner, a status their site says only 3% of agencies in Spain achieve. Offices in Igualada, Barcelona, Madrid, and Hong Kong, with a dedicated eCommerce-in-China service line. Checked 22 July 2026.

Who should pick them: a European brand that needs a store build, a replatform, or a China launch - and wants ads managed by the same company that built the platform. Twenty-five years of engineering endurance is real proof, and very few European agencies can take a brand into Asia at all.

What the six checks find: no ads-specific pricing published, and their ads page shows headline result stats without client attribution - ask whose numbers those are. The honest framing: builders build, specialists scale. If your store already exists and the job is growing it on Shopping, a platform-first shop is running your channel as one service line of many.

The Comparison: All Eight Agencies in One Table

One row per agency, three checks from the rubric. Every cell comes from the agency's own site, with check dates in the sections above. "None published" means we looked and found nothing - it does not mean the agency has no answer, it means you get the answer on their call, on their terms.

	Built for	Pricing on their site	Contract terms they publish
Tinuiti	Enterprise, full-funnel, TV to Amazon	None published	None published
ZenoX Media	6-7 figure/month ecom on Google Shopping	10% of spend tiering to 6%	Month to month
OuterBox	US ecom wanting Shopping + SEO + site work	None published	None published
Vysta	8-9 figure brands, heavy measurement	£1,500-£4,000/month stated range	None published
More Than Scaling	Suspended accounts needing rescue	None published	No long-term contracts, per their site
groas	Stores under $25k/month spend	$1,499/mo published Jul 2026; none today	No lock-ins, per their site
Trilogi	EU store builds, replatforms, China	None published	None published

When ZenoX Is the Wrong Call

An honest roundup includes the cases where the author loses. Here are ours.

Your spend is under roughly €5k/month. The fee math does not work - the management cost crowds out the media budget it is supposed to improve. At that stage, learn the feed basics yourself: rewrite your top titles against your search-term report, fix your disapprovals, and scale spend first. Every check in this guide doubles as a to-do list for doing it solo, and the consultant vs agency vs DIY guide maps which path fits which spend level. If a fee still tempts you at that size, groas' flat $1,499 is the cheaper experiment.

You want every channel in one room. We run Google Ads. Not Meta, not TikTok, not Amazon, not email. If you want one agency coordinating all of it under a single strategy, that is Tinuiti at enterprise scale or More Than Scaling at a smaller one - not us.

You need big named public case studies. Our proof is Trustpilot reviews, published pricing, and your own account read live on the first call. If your board wants a deck with household-name case studies on it, Tinuiti's roster carries far bigger names than ours. That is a real difference, and pretending otherwise would fail our own filter.

Your account is suspended. Rescue first, growth second. More Than Scaling has made unban work a named specialty. Come back when the account is alive.

What Should the First Month Look Like, Whoever You Hire?

Feed first, Merchant Center second, structure third, bids last. The order of operations in the first 30 days tells you almost everything about who you hired.

Week 1: teardown. Search-term reports pulled, feed audited against them, disapprovals listed and prioritized. The first batch of title rewrites ships.

Weeks 2-3: structure. Custom labels deployed so SKUs are tiered by margin and velocity. Campaigns restructured: which products run through PMax, which through standard Shopping, what target each tier gets.

Week 4: calibration. Feed changes have propagated through the auction (about 3-7 days per approved update), and Smart Bidding is recalibrating to the new match patterns. Only now do bid targets get tuned against real data.

An agency that proposes bid changes in week one has the order backwards. Bids optimize the auction you are in; the feed decides which auctions you enter. The full breakdown is in what real Google Shopping management looks like, and if you are still weighing whether to hire anyone at all, is a Google Ads agency worth it runs that math straight.

Run the Checks, Then Decide

Shortlist two or three names from the list above. Run all six checks on each: feed receipts, disapproval clock, custom labels, readable pricing, public reviews, exit terms. Get every fee table in writing and ask what feed work is included.

Whoever answers concretely, hire them. The strong answers are specific, dated, and boring. The weak answers are adjectives.

If we made your shortlist: the first call is your Merchant Center pulled up live, disapprovals first, and a plain verdict on whether we can grow the account. We would rather fail your checks honestly than pass them vaguely.

FAQ: Picking a Google Shopping Agency

Who Is the Best Google Shopping Agency?

For a 6-7 figure/month ecom store where Shopping drives most revenue, our pick is ZenoX Media - 200+ ecom brands on Google Ads, 4.8 from 38 reviews on Trustpilot, and published pricing from 10% of spend down to 6%. We run ZenoX, so weigh that. The honest alternatives: Tinuiti for enterprise brands buying many channels at once, More Than Scaling if your Merchant Center is suspended, groas if you spend under $25k/month and want a flat $1,499 fee, and Vysta for 8-9 figure brands that want heavy measurement work.

What Does a Google Shopping Agency Do?

A real one works three layers. The product feed: title rewrites against real search-term data, custom labels, attribute fixes. Merchant Center: clearing disapprovals, keeping shipping and policy data aligned so products stay live. Campaigns: deciding which SKUs run in Performance Max vs standard Shopping, and setting bid targets per product tier. A weak one skips the first two layers and only touches campaign settings, which is where results plateau.

How Do I Choose a Google Shopping Agency?

Filter on the feed, because that is where Shopping is won. Ask three questions: Can you show me recent title rewrites with the search-term data behind them? What exactly happens when my products get disapproved, and how fast? How do you use custom labels to bid by margin? Then check the fee structure - a tiered percentage of spend aligns the agency with your growth, a flat retainer does not. Any agency that answers all three in plain language is worth a call.

How Much Does a Google Shopping Agency Cost?

Most agencies in this list quote on a sales call. The published numbers that exist: Vysta's homepage states most clients invest £1,500-£4,000 a month in management, and ZenoX charges a tiered percentage of monthly Google Ads spend starting at 10% on the first €10k and stepping down to 6% above €150k, each rate applying only inside its own bracket. Whatever agency you pick, get the fee table in writing and check what feed work is included before comparing prices.

What Questions Should I Ask Before Hiring a Google Shopping Agency?

Five: (1) Show me title rewrites you shipped recently and the search-term data behind them. (2) What is your Merchant Center disapproval playbook, with timeframes? (3) How do you use custom labels to bid by margin? (4) Do you run standard Shopping alongside Performance Max, and which SKUs go where? (5) Who actually runs my account day-to-day - can I talk to them? Weak agencies fail by question two.

Should I Hire a Google Shopping Specialist or a General PPC Agency?

If most of your revenue comes through Shopping and PMax, hire for feed depth. A general PPC agency can be excellent at Search and still treat your product feed as an export job. The skill that moves Shopping accounts is feed engineering - query-informed titles, custom labels, disapproval handling - and you can test for it directly with the filter questions regardless of what the agency calls itself.

When Should I Not Hire a Google Shopping Agency?

Below roughly €5k/month in ad spend, the math rarely works - the fee crowds out the media budget and a motivated founder can learn the feed basics themselves. Also skip the agency route if you are unwilling to let anyone touch the product feed: feed changes are where the results come from, and an agency restricted to campaign settings can only babysit.

Is a Google Shopping Agency Worth It?

Above roughly €5k/month in ad spend, usually yes - if the agency actually works the feed. Shopping is won in the product data, and an agency that rewrites titles against real search terms, clears disapprovals fast, and tiers bids by margin does work most store owners never get to. Below that spend level, or with an agency that only touches campaign settings, the fee eats the gain. Run the six checks in this guide before signing anything.
