What is a CSS?
A Comparison Shopping Service is the shopping partner behind eligible Shopping ads and product listings.
Comparison Shopping Service for Google Shopping
For eligible European markets, Systems30 can be the CSS partner behind Shopping ads while Merchant Center remains the product data home.
What CSS means
A Comparison Shopping Service is the shopping partner behind eligible Shopping ads and product listings. Google Shopping is one CSS option. Systems30 can be another for eligible shops.
Merchant Center and Google Ads stay in place
Merchants can keep their existing Merchant Center account and Google Ads account. The CSS follows the Merchant Center account used by the campaign, and Merchant Center admins approve the switch request.
Readiness before switching
Systems30 asks for merchant details, target countries, Merchant Center ID, and admin confirmation so the CSS switch route can be reviewed before a request is made.
Google CSS partner searches
This page is intended for merchants comparing Google CSS partners, checking CSS partner requirements, reviewing the Google CSS partner program, or asking what a Comparison Shopping Service means for Google Shopping ads.
Eligible Google Shopping markets
CSS applies only in eligible programme countries. Systems30 presents the switch as a review and request workflow, not an automatic account change.
Common Questions
Does this replace Merchant Center?
No. You still use Merchant Center for product data, and Google Ads accounts do not need to be switched.
Can my shop use Systems30 CSS?
It depends on the countries you advertise in and whether they are in the CSS programme.
