What are Google Shopping campaigns?

They are product campaigns in Google Ads where each ad shows a specific product with a photo, price and store name. Targeting is based on the Merchant Center feed, and you pay for clicks that lead to the product page.

At what ROAS does a Shopping campaign start to earn?

The break-even ROAS is 1 divided by your margin: 2.0 at a 50% margin and 5.0 at 20%. An electronics store with a 20 to 30% margin needs 3.33 to 5.0, so a positive ROAS in the account is often not enough. A clothing store with a 60 to 70% margin breaks even at 1.43 to 1.67.

What should I do when products are disapproved in Merchant Center?

Find the source first: the store, the integration, a feed rule or the Merchant Center set-up. Then fix bestsellers, seasonal and high-margin products, followed by products with click history and new categories. Fix the long tail in bulk with feed rules, and keep checking for price and availability mismatches between feed and page.

What is a CSS and how much does it really save?

A CSS is a comparison shopping service through which Shopping ads run. CSS partners claim up to 20% lower CPC and up to 25% more clicks for the same budget, but those claims come from the providers rather than independent studies, and partner fees offset part of the saving. We run our own CSS, Feedve. Read more on Shopping ads with a CSS.

How long does it take to launch a Shopping campaign?

The configuration itself takes hours. The real timeline is set by feed preparation and by Google verifying your account and offer. With a tidy catalogue, expect a few working days. If titles, identifiers, images and delivery data need work, it can take a few weeks, and that stage decides later results.

What a Google Shopping agency does

A Google Shopping agency manages your product feed, Merchant Center, campaign structure and sales measurement so that ad budget goes to the products most likely to sell profitably. We run Google Shopping and Performance Max for online stores and optimise bids, product titles, assortment segmentation and profitability.

We measure revenue, margin, ROAS and the potential of product groups, not only clicks. Shopping, the feed, Merchant Center, analytics and conversion optimisation are handled by one team as one system. Campaigns can run on their own or together with Performance Max and our own Comparison Shopping Service (CSS), Feedve.

We are a Google Premier Partner 2026, in the top 3% of Google Ads agencies in Poland, and we run campaigns on 25 export markets.

What Google Shopping is and where products appear

Google Shopping shows your products across Google with a photo, name, price and seller before the user reaches your store. It is not a marketplace. Purchase, payment, delivery and customer service stay with you. It consists of a Merchant Center account, product data, campaigns in Google Ads and free product listings.

You do not choose keywords. Google analyses the product data, the query, the auction context and account history, which makes the feed the most important lever you have.

Merchant Center and the product feed

Merchant Center is the data hub for your store and products. Its data must match what shoppers see on your product pages.

Merchant Center set-up

Domain verification, business details, shipping and returns, a data source and a routine for acting on diagnostics, with monitoring of rejected products and price or availability mismatches.

A good feed

Up to date, complete, unambiguous, written to sell and easy to segment by margin, season and priority.

Key attributes

Product ID, title, description, price, availability, brand, GTIN or MPN, category, variants, and custom labels for margin, season and priority.

Product titles

Titles should reflect how customers search yet stay readable. Electronics, clothing and home furnishings need different structures.

Break-even ROAS: why a positive ROAS is not enough

Break-even ROAS equals 1 divided by your margin. At a 50% margin it is 2.0, and at 20% it is 5.0. The ROAS shown in Google Ads ignores margin, returns, delivery costs and agency fees, and management costs raise the ROAS you need. The figures below are published benchmarks, a reference point rather than a target.

Category	Typical margin	Break-even ROAS	Average category ROAS
Clothing and fashion	60 to 70%	1.43 to 1.67	6.1
Health and beauty	60 to 75%	1.33 to 1.67	6.1
Home and garden	40 to 55%	1.82 to 2.5	4.5
Electronics	20 to 30%	3.33 to 5.0	3.8

Standard Shopping or Performance Max

The data is mixed. Triple Whale, across 18,000 brands, reports an average ROAS of 5.17 for standard Shopping against 2.57 for Performance Max, while Koongo reports Performance Max ROAS 15 to 20% higher in most categories. The gap comes from attribution: standard Shopping works at the bottom of the funnel, Performance Max also buys the top of it.

Our rule of thumb: a young or low-volume account starts with standard Shopping for clean attribution and bid control. A mature account, with dozens of conversions a month, adds Performance Max to scale. If both run, we exclude brand queries from Performance Max and compare total revenue and margin after costs, not ROAS side by side.

How we work

1. Foundations

Audit of the store, data and profitability. We review sales goals, margin and seasonality, the account, Merchant Center, the feed, GA4 and GTM, and how the assortment is split.

2. Launch

Campaign build and feed optimisation. We set up Merchant Center, optimise titles and attributes, segment products, build Shopping or Performance Max campaigns, add exclusions, audiences and remarketing, and test before going live.

3. Growth

ROAS optimisation and scaling. We manage budgets, bids and target ROAS, exclude products without potential, grow bestsellers, test feed and creative, extend to new products and markets, and report revenue, costs and profitability.

Seven areas we diagnose before scaling

Feed. Completeness and whether data matches the product page.
Offer. Price, shipping cost, delivery time, availability, promotions and store credibility.
Profitability. Margin, average basket value, delivery costs, returns and complementary products.
Merchant Center. Disapprovals, price mismatches, availability and policies.
Measurement. Google Ads, GA4, GTM, Consent Mode and revenue reporting.
Structure. Fit to catalogue size, transaction volume and differences in profitability. Performance Max does not go in one bucket without control.
Demand and auction. Seasonality, competitor promotions, traffic costs and, where relevant, a CSS.

How we optimise Shopping campaigns

Product data

Titles built from real queries, complete identifiers and variants, image tests, labels for margin, season and stock, and fixes for price and availability mismatches.

Structure and budget

Separate products by profitability, cut spend on products that get clicks but do not sell, and give bestsellers and high-margin items more share.

Store and offer

If people click but do not buy, the cause may be price, delivery cost or time, missing reviews, a weak product page or a complicated checkout.

Shopping ads with our own CSS, Feedve

A CSS (Comparison Shopping Service) is a price comparison service through which product ads can be run, either Google's own or an external partner's. Switching CSS does not require moving campaigns or losing your Google Ads account history.

We run our own Comparison Shopping Service (CSS), Feedve. Moving to a CSS partner has trade-offs: a partner sub-account does not get free product listings, and the partner's fees can eat part of the saving, at small budgets possibly all of it. We explain the mechanics on our Shopping ads with a CSS page, and you can visit feedve.com.

Selling in other countries with product campaigns

Product campaigns are usually the simplest way into a new market, because the message is built on the product. They need a separate feed with translated titles and attributes, local currency, correct delivery and returns terms and compliance with local rules. Copying a feed and changing the geotargeting usually ends in disapprovals.

One shared campaign for several countries hides market differences, so we separate budgets and reporting. Before launch we check language, currency and price competitiveness, delivery costs and times, returns, Merchant Center requirements and separate ROAS targets.

Feed quality and AI shopping assistants

Merchant Center data also feeds product comparisons in AI assistants, which build on Google's organic Shopping results. Title, attributes, image and price accuracy decide whether you appear, and an AI answer has no second page. A tidy feed is infrastructure, not a trick. See our AI Search optimisation service.

Common Google Shopping mistakes

A raw feed with technical titles.
The whole catalogue in one campaign.
No transaction value in the data.
Judging only by ROAS, or setting an aggressive ROAS target at launch.
Ignoring Merchant Center.
No data on bestsellers and stock.
Changing the campaign instead of fixing the store.
Trusting automation completely.

When Google Shopping is not the right choice

It is a good starting point when products are already searched for on Google, your offer is competitive and your margin pays for acquiring a customer. It is not when:

Your margin is below the break-even point. The problem is the business model.
The catalogue lacks identifiers and reliable attributes.
Your prices are not competitive within a comparable category.
Feed data and product pages do not match.
Your products fall into an excluded or restricted category.

Budget and costs

Google sets no minimum daily budget, but the amount must buy enough clicks to judge results at a conversion rate of around 2%. Published 2026 benchmarks put the average Shopping cost per click at about €0.36 in Europe and the conversion rate at 1.91%, which means an order costs several dozen clicks. A cheap click is not a cheap sale.

The full cost is the media budget, management and the work on the feed and data. We plan from margin and break-even point, not from a budget figure. See Google Ads pricing for how fees are set.
