Best Google Shopping Ads Agency: Top Picks Ranked by Feed Optimization Depth and Performance Max Integration

The best Google Shopping Ads agency is the one that treats Google Merchant Center feed mechanics, Performance Max asset group architecture, custom label segmentation by margin tier, and server-side conversion tracking as one integrated profitability system rather than four separate disciplines. Specifically, Google Shopping has moved past keyword bidding into AI-driven creative and feed-quality competition. As a result, the agency running Google Shopping needs to know how to feed Performance Max the right inputs while preserving margin discipline across thousands of SKUs.

Disclosure: Hustle Marketers publishes this page and lists itself first. Our founder, Ishant Sharma, is listed second. Nobody paid to be listed.

This guide ranks 14 Google Shopping Ads agencies and specialists, weighted heavily toward partners with documented Shopping-specific case studies, Merchant Center expertise, and Performance Max architecture depth. Hustle Marketers leads the list, with Merchant Center and feed work, 591+ client reviews across platforms and PPC management at $600 to $800 per platform per month, month to month. Its founder, Ishant Sharma, who has worked in digital marketing since 2013, is listed second.

Updated for 2027: this edition adds how Google Shopping ads work now, what agentic checkout changes in your feed, what Merchant Center management should include under Google’s current review rules, and a 30-day onboarding plan you can use to judge any agency. This update adds our own Shopping and Performance Max ROAS data and a fee example by ad spend. The other agency entries below are unchanged, so confirm current fees, minimums and partner status directly with each agency before you sign.

Quick Summary

The best Google Shopping ads agency for most online stores is one that fixes your Merchant Center feed before it touches bids, runs Standard Shopping and Performance Max side by side, and reports Google’s cost separately from its fee. This guide ranks 14 picks on those points and gives you the checks to judge any of them.

• The shortlist: 14 agencies and consultants, ranked on feed optimization depth, Merchant Center skill, Performance Max structure, tracking and contract terms. Hustle Marketers publishes this guide and ranks itself first, which we disclose.
• What it costs: management fees run from $600 to $2,500 a month for accessible specialists, $2,500 to $7,500 for mid-market agencies and $7,500 or more for enterprise agencies. A worked example shows how a flat fee compares with a percentage of spend.
• Our own data: in the ecommerce accounts we managed from October 2025 to September 2026, Standard Shopping returned a median 5.62x ROAS and Performance Max 4.95x, while Performance Max took a median 53.1% of spend.
• How to judge an agency: use the eight checks and the 30-day onboarding plan below, and ask who fixes Merchant Center suspensions before you sign.
• When to wait: if purchase tracking is broken or you do not know your margins by product, fix that before you hire anyone.

Why hiring the right Google Shopping Ads agency matters in 2027

How Google Shopping has evolved into Performance Max territory

Google Shopping in 2027 looks fundamentally different from Standard Shopping in 2020. Specifically, Performance Max replaced traditional Search and Shopping for most ecommerce brands because Google’s AI rewards accounts handing over creative inputs and conversion data velocity. As a result, the agency running Google Shopping needs to feed Performance Max the right inputs without losing the visibility and control that ecommerce brands need for margin protection.

However, Performance Max isn’t a complete replacement for Standard Shopping. Notably, the right Google Shopping agency runs both campaign types in parallel: Performance Max for scale across all SKUs, and Standard Shopping for control over high-margin or strategic products. For deeper context, see the mastering Google Shopping blog and the Performance Max and feed optimization guide.

Why Merchant Center feed quality drives every Shopping campaign

Google Merchant Center feed quality drives more Shopping ROAS than any other single factor in 2027. Specifically, product disapprovals, missing GTINs, low-quality images, weak product titles, and missing structured data all reduce ad delivery quality before any bidding strategy even runs. Meanwhile, accounts with optimized feeds achieve 30 to 60 percent higher impression share at the same ad spend.

The 13 tactics that move feed quality most, with the product title formulas by category, are in our guide to how to rank in Google Shopping. Most account-level Merchant Center suspensions are misrepresentation suspensions, which have their own appeal process and evidence requirements.

The right Google Shopping agency audits Merchant Center feed quality before touching any campaign settings. For audit framework depth, see the AI feed optimization guide and the Google Merchant Center Next guide.

GTIN, custom labels, and the data quality moat

Three feed-level levers separate strong Google Shopping agencies from generic ones. First, GTIN (Global Trade Item Number) accuracy across every SKU, which Google uses for product matching and price competitiveness scoring. Second, custom label structures that segment products by margin tier, AOV band, inventory velocity, and seasonality flag. Finally, supplemental feeds for promotional pricing, sale flagging, and seasonal product activation.

For deeper GTIN context, see the GTIN Google Shopping guide. Additionally, the supplemental feed guide covers promotional pricing setup. Finally, the Shopping annotations and badges guide covers the visual lift mechanics.

Free product listings and what they mean for paid Shopping

Free product listings in Google Merchant Center expanded dramatically since 2020. Specifically, the free Shopping tab listings, free local inventory ads, and free product results across Google Search drive 20 to 40 percent of total Shopping traffic for optimized accounts. As a result, the right agency claims and optimizes free listings alongside paid Shopping campaigns.

For setup depth on free listings, see the free listings in Google Merchant Center guide and the business agent in Merchant Center guide. For a worked example, our supplement Google Ads case study shows free listings, product ratings and paid Shopping running together for a probiotic brand.

Optimizing products for these free listings is often called Google Shopping SEO. Free listings draw on the same Merchant Center product data as paid Shopping ads, so a Google Shopping SEO agency and your paid Shopping agency should work from one feed, not two. Our comparison of free Shopping listings vs paid ads shows where each one appears.

How we ranked the best Google Shopping Ads agency picks

Five filters were applied. First, documented Google Shopping case studies with disclosed ROAS data, not generic ecommerce case studies. Second, demonstrated Merchant Center feed expertise including custom label setup, GTIN compliance, and disapproval handling. Third, Performance Max architecture depth covering asset groups, brand exclusions, and audience signals. Fourth, server-side conversion tracking implementation across iOS Safari ITP environments. Finally, contract flexibility with month-to-month engagement options.

After applying these filters, the list combines Hustle Marketers with fourteen named industry providers whose work spans dedicated Google Shopping specialists, broader Performance Max practices, and full-service ecommerce PPC agencies.

Shopping ads agency vs ecommerce PPC agency vs Performance Max agency: what is the difference?

A shopping ads agency manages Google Merchant Center, your product feed and Shopping or Performance Max campaigns; an ecommerce PPC agency does all of that plus search, Microsoft Advertising, remarketing and often Meta; a Performance Max agency focuses on PMax structure and controls. Most online stores need the middle option, because feed, search and tracking decisions affect each other. If you sell in the US, our list of Google Ads agencies for ecommerce brands compares ten of them.

When you search for ecommerce PPC agencies, you will see all three labels used loosely. Ask each agency what it touches every week. If the answer does not include your product feed and the Merchant Center Needs attention tab, it is not a Shopping specialist, whatever its website says.

Ishant Sharma, founder of Hustle Marketers, says a PPC agency for ecommerce should be judged by what it changes in your product data, not only by what it changes in Google Ads.

What do Google Shopping management services include?

Google Shopping management services cover the recurring work that keeps product ads profitable: Merchant Center upkeep, feed changes, campaign structure, bids and budgets, search terms and negatives, tracking checks and reporting. A good Google Shopping management agency puts the cadence for each task in writing, so you can see what was done every week.

Use this table as a baseline when you compare proposals:

If a proposal leaves out the feed and Merchant Center rows, you are buying bid management, not Google Shopping management. It is the same test as the agency types table above. To see how we package this work, read about our ecommerce PPC management services.

Should you hire a Google Shopping expert, a consultant or an agency?

Hire a Google Shopping expert or consultant when someone on your team already runs the account and you need senior review, an audit or a rebuild plan. Hire an agency when you need weekly execution across the feed, campaigns and tracking. Hire in-house only when your spend can fund a full-time specialist with access to your product data.

The list below includes both kinds of provider. Ishant Sharma offers hourly consulting alongside retainers and ZATO Marketing is owner-led by Kirk Williams, while most of the other picks are agencies with account teams.

The best Google Shopping Ads agency picks, ranked

1. Hustle Marketers

Hustle Marketers is a PPC and SEO agency founded in 2020 by Ishant Sharma, who has worked in digital marketing since 2013. It is a Google Partner, Meta Business Partner and Microsoft Advertising Partner with 591+ client reviews across platforms, $780M+ in trackable client revenue across 2,500+ brands and Clutch Award wins in 2023, 2024 and 2026. The delivery team works from Zirakpur, India, with clients worldwide. Meetings happen online.

Hustle Marketers publishes this page and lists itself first, so every fact below links to a place you can check it.

What does Hustle Marketers do for Google Shopping?

Hustle Marketers (hustlemarketers.com) is a Google Partner agency, founded in 2020 by Ishant Sharma, that manages Google Shopping for ecommerce stores: it fixes the Merchant Center feed, runs Standard Shopping and Performance Max side by side, and builds negative keywords before launch, for US$600 to $800 per platform a month.

In SolBiome’s account the Merchant Center feed was optimized before spend was scaled, and the store now shows Google’s Top Quality Store badge and five stars from 188 product ratings on its Shopping ad. In Hustle Marketers’ benchmark, Standard Shopping beat Performance Max at the median, yet each came out ahead in four of the nine accounts that ran both, with one tie (same-account comparison), so Hustle Marketers tests both inside your own account instead of following a rule. For a newer store, MiKi Jewellery, a Western Australian jewelry brand, reached 7.81 conversion value per cost on A$2.88k spend in 47 days from a new Google Ads account (MiKi Jewellery case study).

Hustle Marketers also runs Microsoft Shopping next to Google Shopping, from the same feed source, for brands such as ArmorPoxy and ArmorGarage. Microsoft gets its own budget and a one-time campaign import with no scheduled sync, so Google budget changes do not carry over. See how we run Google and Microsoft Shopping together.

Quick comparison: Google Shopping Ads agencies side by side

Google Shopping Ads management pricing tiers in 2027

Tier 1: Accessible Shopping specialist ($600 to $2,500 monthly)

Accessible Shopping specialists serve small ecommerce brands and growth-stage operators with senior practitioner attention at SMB pricing. Specifically, Hustle Marketers operates the most accessible Tier 1 option at $600 to $800 monthly per platform with full Merchant Center feed audit and Performance Max architecture included.

Tier 2: Mid-market Shopping agency ($2,500 to $7,500 monthly)

Mid-market Shopping agencies serve established ecommerce brands with structured account management and broader feed optimization scope. Notably, SmartSites, WebFX, and ZATO Marketing operate in this range with dedicated Shopping strategists.

Tier 3: Enterprise Shopping agency ($7,500+ monthly)

Enterprise Shopping agencies serve large ecommerce brands with dedicated strategist teams and proprietary platforms. Specifically, Tinuiti, KlientBoost, Disruptive Advertising, and Logical Position operate at this tier. Importantly, these agencies typically require $50,000+ monthly ad spend to justify the engagement scope.

How much ad spend do you need before a Google Shopping agency pays for itself?

A Google Shopping agency pays for itself when the extra gross profit it produces is larger than its fee. At an example 40% gross margin, a $700 monthly fee needs $1,750 of extra monthly revenue just to break even. That is a small lift on a large account and a big one on a small account.

This worked example uses example numbers only: a flat fee of $700 a month, a fee of 10% of ad spend, and a 40% gross margin.

Two things follow from the math. Below about $5,000 a month, any fee is a large share of spend, so the agency has little budget to work with whichever model you pick. Above $7,000 a month, a $700 flat fee costs less than 10% of spend, and the gap keeps widening as spend grows.

The $700 figure sits inside our own $600 to $800 range, and 10% sits inside the 7% to 12% range one agency publishes in the fee table further down. Swap in your real margin and fees with our ROAS calculator with break-even and contribution margin.

Realistic Google Shopping ROAS benchmarks by ecommerce vertical in 2027

Does Standard Shopping or Performance Max deliver a higher ROAS?

In the ecommerce accounts we managed over the 12 months to September 2026, Standard Shopping delivered a slightly higher median ROAS than Performance Max: 5.62x against 4.95x, even though Performance Max took a median 53.1% of account spend. The figures come from our benchmark study of 22 Google Ads accounts.

The study, Google Ads Performance Benchmarks by Campaign Type (Sharma, 2026, published on Zenodo), covers 14 ecommerce and 8 lead generation accounts. ROAS is conversion value divided by cost inside each account, so currency does not change it. Our Google Ads ROAS data by campaign type has the full table and method.

Median ROAS by campaign type in ecommerce accounts managed by Hustle Marketers, 1 October 2025 to 30 September 2026:

Source: Sharma (2026), Google Ads Performance Benchmarks by Campaign Type, Zenodo. Performance Max took a median 53.1% of ecommerce account spend.

Three points matter when you hire a Google Shopping agency:

• The weak end differs most. A quarter of the Performance Max accounts sat at or below 1.87x, against 4.17x for Standard Shopping, so Performance Max needs closer watching when margins are thin.
• Brand traffic lifts the average. Brand Search returned more than five times the ROAS of non-brand Search. Performance Max can show ads on brand searches unless brand exclusions are set, so ask for brand and non-brand results reported separately.
• Standard Shopping has not gone away. It ran in 9 of the ecommerce accounts with a tighter middle range than Performance Max, so ask how an agency splits products between the two campaign types, not which one it prefers.

These medians describe one agency’s portfolio, and the samples per campaign type are small, so treat them as a reference point rather than a target. The number that decides whether Shopping pays for you is your own break-even ROAS: 1 divided by your gross margin, so an example 40% margin gives a break-even ROAS of 2.5x.

When should an agency run Standard Shopping, Performance Max or both?

Run Standard Shopping when you need query-level control and clean reporting, Performance Max when you want reach across Google’s channels from one feed, and both when your catalog mixes proven sellers with products that still need testing. Google serves the campaign with the highest Ad Rank when they overlap, so the split has to be planned.

Performance Max is less of a black box than it was. Google Ads Help (checked October 2026) says every Performance Max campaign can now use campaign-level negative keywords for Search and Shopping inventory, and that search terms reporting is available for all Performance Max campaigns alongside channel performance reporting. Ask any agency to show you all three in your account.

For the setup, see our guides to Performance Max negative keywords and Performance Max asset group structure for ecommerce.

How do Google Shopping ads work in 2027?

Google Shopping ads are built from your product feed, not from ad copy. Merchant Center holds the product data, Google matches it to searches, and a Shopping or Performance Max campaign in Google Ads sets the bids. The feed decides which searches a product can show for, so most of a Shopping agency’s real work happens in Merchant Center.

The data pool is large and moves fast. In January 2026, Google said its Shopping Graph holds over 50 billion product listings, with more than 2 billion of them refreshed every hour (Google, NRF 2026 remarks). Prices and stock that lag behind your site compete against listings that update faster.

Performance Max is now the default route for most stores. Google said in April 2025 that it was used by over one million advertisers, and it added a channel performance report covering Search, YouTube, Discover, Gmail, the Display Network, Search partners and Maps, along with full search terms reporting. In Performance Max, brand exclusions apply to both Search and Shopping ads, and you can allow Shopping ads to keep serving for the excluded brand terms. Ask any agency which setting it uses for your brand and why.

How does agentic checkout change feed management?

Agentic checkout adds feed attributes that a Shopping agency now has to manage. Google introduced the Universal Commerce Protocol in January 2026 for buying directly on Google surfaces such as AI Mode and Gemini, and a product only shows a buy button if its feed opts it in.

Some products cannot use checkout on Google at all, including subscriptions and installments, personalized goods, pre-orders, age-restricted items, services, rentals and virtual goods. Google’s UCP Merchant Center guide recommends sending these attributes through a supplemental data source, so a mistake does not break the main feed. Our guide to Merchant Center AI attributes covers the wider set.

What separates strong Google Shopping agencies from average ones

Server-side conversion tracking through Merchant Center

Strong Google Shopping agencies operate server-side GTM through Stape, Google Cloud Run, or comparable server containers. As a result, server-side tracking restores 30 to 50 percent of conversion signal lost to iOS Safari ITP and consent mode compliance environments.

Custom label segmentation by margin tier

The right Google Shopping agency builds custom label structures in the Merchant Center feed that segment products by gross margin tier. Specifically, custom label 0 handles gross margin tier (Premium, Standard, Loss-Leader). Then custom label 1 handles AOV band. Meanwhile, custom label 2 handles inventory velocity. Finally, custom label 3 flags seasonality.

Performance Max architecture with focused asset groups

Strong Shopping agencies build Performance Max with one asset group per margin tier rather than one campaign covering all SKUs. Importantly, brand search exclusions are enabled by default to prevent cannibalization of branded search traffic at cheaper costs. For PMax depth, see the PMax checklist and the Best Performance Max agency guide.

Free listings claimed and optimized alongside paid Shopping

The right Google Shopping agency claims and optimizes free product listings alongside paid Shopping campaigns. Specifically, free Shopping tab listings, free local inventory ads, and free product results drive 20 to 40 percent of total Shopping traffic for optimized accounts.

What does Merchant Center management include, and who fixes suspensions?

Merchant Center management covers four jobs: feed health, policy compliance, business verification and review requests, and the agency linked to your account should handle all four. Your business still owns the account and supplies documents when Google asks, while the agency runs the diagnosis, the fixes and the review requests.

Sources: Google’s Misrepresentation policy and Request a review of your issues pages, checked October 2026.

Use these rules to test an agency’s answer to check 6 below. The clause-by-clause list is in our Google Merchant Center requirements guide, and our Merchant Center audit template turns it into a checklist you can hand to any agency.

What are the key benefits of hiring an ecommerce PPC agency?

The key benefits of hiring an ecommerce PPC agency are one team owning feed, campaigns and tracking together, faster fixes when Merchant Center disapproves products, pattern knowledge from many stores, and your own time back to run the rest of the business. The trade-off is a monthly fee, so the benefits only pay off once ad spend and margins can support it.

• Feed and campaigns in one place: titles, product types and custom labels change because of what search terms and margins show, not in isolation.
• Faster recovery from disapprovals and suspensions: an experienced team has seen the common causes, such as missing GTINs, price mismatches, shipping and returns gaps and misrepresentation flags.
• Clean measurement: purchase tracking, enhanced conversions and deduplication are set up once, so bidding learns from real orders.
• Wider reach from the same feed: the product data that powers Google Shopping can also power Microsoft Shopping and Meta catalogs.
• Pattern knowledge: an agency sees seasonality, policy changes and Google product updates across many stores at once.
• Your time back: weekly search term reviews, feed fixes and bid strategy changes stop landing on the founder’s desk.

At Hustle Marketers we tell prospects the biggest benefit is accountability: one team answers for blended results across Shopping, Performance Max, Search and Microsoft, instead of three vendors blaming each other. If you are weighing the alternative, read PPC agency vs in-house and our Shopify Google Ads guide.

When should you not hire one yet?

Do not hire an ecommerce PPC agency yet if purchase tracking is broken, your Merchant Center account is suspended for a reason nobody has diagnosed, you do not know your margins by product, or your ad budget is so small that the fee would take most of it. Fix those first, because no agency can scale spend profitably on bad data.

Our test before taking on any ecommerce account is one question: can you name which products make money after ad costs? If not, start with break-even ROAS and tracking, not more budget. Our guide to ecommerce PPC for small businesses shows how to run a lean setup first.

What should I be doing in place of having an advisor when you don’t have a budget to hire an agency?

Without budget for an agency, run a small structure yourself and review it weekly: keep Merchant Center clean, run one brand search campaign plus one Shopping or feed-led Performance Max campaign, read the search terms report, and fix product data before touching bids. A merchant asked this exact question in the Shopify Community in February 2026.

• Check the Needs attention tab in Merchant Center every week and fix each issue at the source in your store.
• Add a product type at least three levels deep, as Google recommends in its free listings guidance, and use custom labels for margin tiers.
• Work through our free Google Ads audit checklist before and after any big change.

Common Google Shopping mistakes ecommerce brands make

Running default Merchant Center feed without custom labels

Many ecommerce brands launch Google Shopping with default Merchant Center configurations that treat all SKUs equally. However, the right agency builds custom label structures from day one. As a result, margin-aware bidding becomes possible across thousands of SKUs.

Letting Performance Max cannibalize Standard Shopping and branded search

Performance Max by default bids on branded queries and overlaps with Standard Shopping unless brand exclusions and negative keywords are explicitly configured. Specifically, the right Google Shopping agency enables brand exclusions on every Performance Max campaign by default and excludes branded queries from PMax to preserve cheaper branded search performance. Google Ads Help (checked October 2026) also says Performance Max may filter out navigational or brand-specific queries so a dedicated brand Search campaign can serve them, which only works if that campaign has enough budget and eligible ads.

Ignoring GTIN and product identifier optimization

Products without accurate GTINs face lower impression share, higher CPCs, and reduced ad delivery quality. Notably, GTIN compliance also unlocks price competitiveness scoring. For depth, see the GTIN Google Shopping guide.

Skipping supplemental feeds for promotional pricing

Many ecommerce brands run promotional pricing through their main feed, which causes data sync delays and disapprovals. Instead, the right approach uses supplemental feeds for promotional pricing, sale flagging, and seasonal product activation. For setup, see the supplemental feed guide.

Not claiming free listings in Merchant Center

Free Shopping tab listings, free local inventory ads, and free product results require explicit activation in Merchant Center. As a result, brands that skip free listings setup miss 20 to 40 percent of available Shopping traffic. For setup, see the free listings guide.

What should I look for in a Google Shopping ad agency? 8 checks

Look for a Google Shopping ad agency that audits your Merchant Center feed before quoting, already knows about the Content API to Merchant API change, keeps the accounts in your name, puts its fee in writing, states a minimum spend, has a disapproval playbook, understands campaign overlap rules and reports by channel.

The next section covers feed audits, Performance Max structure, case studies and server-side tracking in more depth. The eight checks below are the contract, data and reporting questions most buyers forget to ask.

Three of these checks rest on Google’s own rules. Google’s developer documentation confirms the Content API for Shopping was sunset on 18 August 2026, with progressive errors from 1 September 2026, so an app or script still using it can quietly stop updating products (our Content API shutdown checklist covers the fix). Google’s Help Center explains how Performance Max interacts with other campaigns: the campaign with the highest Ad Rank serves, but a Search keyword that exactly matches the query is preferred over PMax. Google’s transparency requirements for third parties also tell agencies to report “the exact amount charged by Google, exclusive of any fees that you charge.”

For check 6, compare the agency’s answer with our guides to Merchant Center suspensions and misrepresentation appeals. For check 7, see Performance Max vs Search.

Which ecommerce PPC agencies publish their fees?

Few ecommerce PPC agencies publish their fees, but the agencies below each state a fee, a fee model or a minimum on their own websites, which makes them easier to compare before a sales call (checked on 24 September 2026):

Which ad agency do you recommend for running ads?

The best ad agency for an online store is one that passes the eight checks above for your budget, so shortlist two or three and ask each for an audit of your own account before you compare prices or sign anything. When a merchant asked this question in the Shopify Community, most replies came from service providers, several of them promoting their own agencies, which is why a structured check works better than a thread of names.

At Hustle Marketers our rule is simple: any agency worth hiring should show you a real problem in your feed or account before you pay it anything.

What should a Google Shopping agency do in the first 30 days?

In the first 30 days, a Google Shopping agency should audit and fix your product data before it changes bids: one week of audit, one week of fixes at the source, one week of campaign structure, then one week of launch and reading the data. Use the plan below to judge any agency’s onboarding proposal.

Two numbers show whether the plan is working by day 30: the share of products disapproved or pending, and the share of spend going to products above break-even ROAS. If an agency cannot report both, it is managing campaigns, not your catalog.

• Set the line first with our guide to calculating break-even ROAS.
• If you sell on Shopify, check for duplicate product sources in week 1; our guide to Shopify Merchant Center data sources explains the fix.
• Keep the disapproved or pending share under about 20%, the level Google looks at before it raises a product quota.

How to choose the right Google Shopping Ads agency

Will the agency audit your Merchant Center feed before signing?

Ask for a feed audit covering product disapprovals, missing GTINs, image quality issues, title optimization opportunities, and custom label opportunities. Specifically, the audit deliverable should run 10 to 20 pages and ship within 5 business days. Notably, Hustle Marketers offers a free 13-section Google Ads audit including the Merchant Center feed review.

How does the agency structure Performance Max for Shopping?

The right answer covers multiple asset groups segmented by margin tier, brand exclusions enabled by default, audience signals built from first-party customer lists, and Standard Shopping running in parallel for high-margin SKU control.

What verifiable Google Shopping case studies can the agency share?

Ask for case studies in your specific vertical and ad spend range. As a result, the case study evidence either matches your situation or doesn’t. Specifically, Hustle Marketers shares Silicon Lightworks Merchant Center optimization and P-REX Hobby 9x ROAS as verified Shopping work.

Server-side conversion tracking implementation experience

Ask the agency directly how they would configure server-side conversion tracking for your specific ecommerce platform. Importantly, the right answer covers server-side GTM container setup, enhanced conversions, Meta Conversions API in parallel, and platform-native pixel deduplication.

Common questions about hiring a Google Shopping Ads agency

Meanwhile, mid-market agencies charge $2,500 to $7,500 monthly. Finally, enterprise agencies charge $7,500 to $25,000+ monthly.

What’s the difference between Performance Max and Standard Shopping?

Performance Max runs Google’s AI-driven cross-channel campaign type across Search, Shopping, Display, YouTube, and Discover. In contrast, Standard Shopping runs Shopping ads only, with negative keyword control, manual or automated bidding and full search term visibility. As a result, most brands run both in parallel: PMax for scale, Standard Shopping for control over high-margin SKUs.

Do I need GTINs for every product?

Yes for any product with a manufacturer-assigned GTIN. Specifically, products without accurate GTINs face lower impression share, higher CPCs, and reduced ad delivery quality. However, custom products, handmade items, and products without manufacturer GTINs can be flagged with the identifier_exists attribute set to FALSE.

How long until Google Shopping shows ROI?

Most Google Shopping campaigns show measurable ROI within 30 to 60 days. Specifically, initial Shopping campaigns launch within 5 to 10 business days. Then Smart Bidding gathers conversion data through days 30 to 60. As a result, most agencies use a 90-day window to demonstrate first measurable lift.

Should I use a Shopping-specialist agency or a generalist?

Choose a Shopping specialist when Shopping drives more than 50 percent of ecommerce revenue and the catalog exceeds 100 SKUs. In contrast, choose a generalist when Shopping is one of several channels and the ecommerce operation needs Meta Ads, content marketing, or SEO coordinated under one vendor.
