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 yourself, without having to rely on a third-party CSS – and why the price comparison toolkit from Label Up makes this process much easier for you.

Overview: What is Google CSS?

Before you embark on the path to participating in Google CSS, 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 advertise their products on Google Shopping and PMAX. These services provide consumers with the opportunity to compare products and prices from various providers in an organized manner on Google.

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

The Requirements for Your Own Google CSS

To be recognized as a CSS partner at Google, you must meet certain prerequisites. 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 compare

• a clear representation of the products including name, price, and image

• linking each product 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 possess the knowledge and resources to continuously operate and optimize the website. 

All Requirements for a Google CSS Partnership at a Glance: 

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 function perfectly, 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. You will receive access to the Google CSS Center from Google once you have been accepted into the CSS program.

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

• Your CSS website (landing page): It presents the products clearly with price, image, and direct linking 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: Once your CSS is actively chosen, the CSS name appears under your customers' shopping ads. If a user clicks on it, they will be redirected for free to your CSS page.

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