As a retailer on Google Shopping or as a performance marketing agency in the field of online marketing and Google Ads, participating in the Google CSS (Comparison Shopping Service) program is a great advantage. The CSS partnership can not only increase your customers' visibility on Google Shopping but also significantly improve the efficiency and ROI of your campaigns. In this article, you will learn step by step how to become a Google CSS partner yourself, without relying on a third-party CSS – and why Label Up's comparison shopping toolkit makes this process incredibly easier for you.

Step 1: What is CSS and why should you become a Google CSS partner?

Before you embark on the path to participate in Google CSS, you should know exactly what the Google Comparison Shopping Service (CSS) actually is. A CSS is a price comparison portal that allows retailers & e-commerce platforms to advertise their products on Google Shopping and PMAX. These services give consumers the opportunity to compare products and prices from various providers clearly on Google.

If you operate your own price comparison portal as an agency and present yourself as a Google CSS partner, your customers' shopping ads will appear with your CSS name. Your own name under the shopping ad?  – that gives you more control, visibility, and better conditions with Google support. 

Step 2: The requirements for your own CSS partnership 

To be recognized as a CSS partner by Google, you must meet certain requirements. Central to this is the operation of a standalone and functional price comparison platform that complies with Google’s guidelines.

The most important criteria from Google are:

·  at least 50 merchants per country in your portfolio to compare

·  a clear presentation of products including name, price, and image

·  a link of each product to the respective shop, so that users can buy directly

·  at least two filtering options to sort products sensibly (e.g. by price, brand, category)

If you want to build your own price comparison site - without relying on a white-label solution like Label Up - technical know-how is essential. Your agency should have the knowledge and resources to continuously operate and optimize the website. 

 Step 3: The technical infrastructure of a Google CSS partner

The technical infrastructure of a Google CSS partner consists of four main elements, the interplay of which ensures flawless performance. 

For your own CSS to function properly, four central components must work together:

• Google CSS Center: Here you manage all connected merchant accounts, activities, and settings. Through your CSS Center, you can invite shops to your price comparison portal with just three clicks.

• Merchant Center: Merchants select your CSS there. Product data must be updated regularly – manually or via automated feeds.

• Your CSS website (landing page): It displays the products clearly with price, image, and direct links to the respective shop. Technical interfaces (APIs) must be set up and maintained between the CSS Center and the landing page.

• Shopping Ads on Google: As soon as your CSS is actively selected, the CSS name appears under your customers' shopping ads. When a user clicks on it, they are taken directly to your CSS page for free.

💡 Tip: With the CSS white-label solution like Label Up, this entire process – including API maintenance, updates, and domain integration – is automated for you.

Step 4: Becoming a Google CSS partner without 50 Merchant Centers – is that possible?

Google requires that you have at least 50 Merchant Centers in your portfolio for the CSS partnership. This is a high hurdle, especially for smaller agencies, freelancers, or startups. Here, Label Up's white label software offers you a clever solution. Our price comparison platform is Google-certified and meets all requirements. Even if you manage fewer than 50 Merchant Centers, you can have your customers "supplement" through Label Up. This way, you fulfill the conditions without having to build a complex infrastructure yourself. You also don't have to worry about verification with Google with Label Up.
