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 significant 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 without relying on a third-party CSS – and why the price comparison toolkit from Label Up makes this process much easier.

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

Before you embark on the path to Google CSS participation, you should know exactly what the Google Comparison Shopping Service (CSS) actually is. A CSS is a price comparison portal that enables retailers & e-commerce platforms to promote their products on Google Shopping and PMAX. These services provide consumers with the ability to compare products and prices from various providers clearly on Google.

If you run 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's name. Your own name under the shopping ad?  – this 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 an independent 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 be compared

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

·  each product linked to the respective shop so that users can buy directly

·  at least two filtering options to sort the 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, whose interplay ensures flawless performance. 

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

• Google CSS Center: Here, you manage all connected retailer accounts, activities, and settings. Through your CSS Center, you can invite shops to your price comparison portal with just three clicks. Access to the Google CSS Center is granted by Google once you are accepted into the CSS program.

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

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

• Shopping Ads on Google: Once your CSS is actively chosen, the CSS name appears under your customers' shopping ads. When a user clicks on it, they are directed free of charge directly to your CSS page.

💡 Tip: With the CSS white-label solution like Label Up, this entire process – including API maintenance, updates, and domain integration – is automatically taken care of 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 CSS partnership. This is quite a high hurdle for smaller agencies, freelancers, or startups. Here, the white-label software from Label Up offers you a clever solution. Our price comparison platform is Google-certified and meets all requirements. Even if you handle fewer than 50 Merchant Centers, you can have your customers "top up" through Label Up. This way, you meet the conditions without having to build a complex infrastructure yourself. You also need not worry about the verification with Google with Label Up.

Conclusion - How to become a Google CSS partner
