Introduction
Google Shopping visibility matters to European webshops because the service placing their products affects how campaigns are managed and paid for. In Google’s European CSS-program countries, a webshop needs a Comparison Shopping Service, but it can use Google’s own service or an independent partner. Producthero led an independent-partner merchant-count comparison in 2023, with us at Shoparize second; the better choice for your store depends on its markets, who manages its ads, and the full charging arrangement.
What is a Google Shopping partner (CSS) and why is it required in Europe?
A Comparison Shopping Service, or CSS, is the service through which a merchant can place Shopping ads or free product listings in the European countries covered by the CSS program. Google requires merchants to work with at least one CSS in those countries, and Google Shopping itself qualifies. You do not have to choose an independent CSS to meet the requirement.
The listed countries include the United Kingdom and Switzerland, so this is not solely an EU rule. A merchant can also work with several CSSs at once. The arrangement follows the European Commission’s finding that Google favored its own comparison shopping service in general search results; the Court of Justice dismissed Google’s appeal in 2024.
A CSS is distinct from a Google Ads agency, and while Google Shopping agencies in Europe can manage your account, a CSS is the service used to place the Shopping products. One business can take on both responsibilities, but working with Google Shopping ecommerce agencies does not by itself settle which CSS your products use.
Is Google Shopping still a thing — and still worth using in 2024–2025?
Yes. Google’s CSS guidance describes both Shopping ads and free product listings in its listed European countries. Whether paid ads are worth using is a separate financial decision: sales attributable to the campaigns must justify ad spending and partner charges.
Merchant adoption is not a substitute for that calculation. The 2023 CSS Partner Report analyzed 22,069,973 selected Shopping ads from 140,736 webshops across 21 countries, but its merchant counts do not tell you what your own campaigns will earn. Assess paid Shopping against your margins and the cost of acquiring the sales, rather than a partner’s size.
How are Google Shopping ads created, and what does a CSS actually do?
Your product information starts in Merchant Center. The CSS arrangement then determines who handles the feed, bidding, and campaigns. Google describes services that manage feeds and campaigns as well as tools that leave those tasks with the merchant.
Under a self-service arrangement, you can own and manage the Google Ads account while using an independent CSS. Under a managed arrangement, the CSS can own and run the campaigns, with ads that send shoppers directly to your product pages. Another CSS-owned format sends shoppers first to the CSS’s product-detail page, where they can compare merchants and prices. Confirm the destination before agreeing to a managed service: it changes the path your customer takes to reach your store.
A CSS can also work with an existing feed rather than replace it. Feed optimization and campaign ownership are separate responsibilities, so establish which party can change product data and which controls spending.
How do I get listed in Google Shopping in the first place?
Start with product information in Merchant Center, then establish which CSS will place your products in each relevant market. Google Shopping qualifies as that CSS, so an independent-provider switch is not a prerequisite for getting listed.
The setup depends on the route. For our Managed Ads service, you need a Merchant Center product feed, a store in a supported European market, and the ability to install a tracking plugin. Our Premium CSS service supports campaigns you run yourself without a new feed or account migration. For comparison listings, you supply a feed; shoppers find products on our site and complete purchases in your store.
These are different placements and account arrangements, not interchangeable ways of describing the same listing. Before setup, confirm the destination of the listing and who needs access to Merchant Center and Google Ads.
Who are the top Google Shopping / CSS partners in Europe?
Producthero was first and we at Shoparize were second among independent CSS partners by merchants found in the 2023 CSS Partner Report. Velka, Kelkoo, and Redbrain followed; the remaining names in its top ten were Smarketer, ShopForward, Adference Shopping, Trovaprezzi, and Bigshopper. Google’s own CSS was excluded.
That order measures merchant presence in selected ads, not campaign performance. Producthero was also first by frequency of Shopping ads found, while we were eighth on that measure. The report identified 817 CSS partners in its sample and found that not every partner was active in all 21 CSS-program countries. A prominent partner is therefore a candidate to assess, not a guarantee that it covers your markets or suits your campaign team.
What service models do Google Shopping partners offer (managed, self-service, hybrid)?
In a self-service arrangement, you retain campaign control and pay the CSS for its service. This fits a webshop with the capacity to manage its own Google Ads spending and product data. Our Premium CSS service follows that model without requiring a new product feed or account migration.
In a managed arrangement, the provider runs the campaigns. With our Managed Ads service, we run and fund campaigns across Google and Bing; you supply the feed and pay for generated sales rather than clicks or impressions. This transfers day-to-day campaign work, but it also makes the definition and tracking of a generated sale central to the agreement.
A hybrid divides responsibilities instead of assigning everything to one side. CSSs can tailor their services, and a single provider can support multiple models. We allow Premium CSS and separately funded Managed Ads to operate together. The decisive comparison is therefore not the provider name alone, but who owns the account, changes product data, sets spending, and pays the media bill.
How much does a Google Shopping partner cost?
The pricing model should match the work the partner performs. A fixed subscription gives a merchant running its own campaigns a predictable CSS charge, while managed services can charge per click or take a commission on sales following ad clicks. Your ad spending and any partner fee both belong in the cost calculation.
Our published Premium CSS price is €27 per month per Merchant Center, plus €21 per additional shop, with no sales commission. We advertise a 30-day trial without a credit-card requirement. For Managed Ads, we fund the campaigns and charge for generated sales rather than clicks or impressions; the sales-based terms need to be assessed alongside the value of the management provided.
Comparison-site listings have separate prices. We list Comparison Listings at €33 per month with annual billing, plus €25 per additional shop and a sales commission. Our monthly Comparison Shopping price is €47 per month plus a sales commission. Check which service and billing term a quote covers before comparing its headline price with a CSS subscription or managed-campaign proposal.
How do I find and switch to the right CSS partner?
Filter Google’s partner portal by country, industry, and supported language; it also has filters for API feed technology and premium partners with additional technical certification. Shortlist providers that cover your actual selling markets, then compare who owns the campaigns, who changes the feed, and every fixed or variable charge.
Before approving a switch, establish the required Merchant Center and Google Ads access and the approval step in Merchant Center. Existing campaigns do not necessarily need rebuilding. For our Premium CSS switch, we state that a switch from Google’s own CSS completes within 24 hours without interrupting existing campaigns. Confirm that the proposed process applies to your accounts before changing their CSS association.
The best partner is the one that fits the operating arrangement
Producthero led the 2023 independent-partner comparison by merchant count, but that position does not determine the best service for every webshop. The right choice depends on market eligibility, campaign and account control, and the complete billing arrangement. Confirming those terms before approving a CSS switch gives your team a basis for continuous optimization without an avoidable change to existing campaigns.
