Finding the right CSS partner
How to identify eligible CSS partners, migrate your Merchant Center from one CSS to another, and avoid the typical pitfalls during the switch.
Finding eligible CSS partners
You can find eligible CSS partners in Google's Comparison Shopping Partners portal. Use filters such as country, industry or supported language to identify CSSs that match your business needs.
You can also filter for partners that offer API feed technology, or for premium partners that have additional technical certification and support conversion tracking for merchants.
Switching an account from one CSS to another
To keep your existing Merchant Center account while working with a different CSS, Google can migrate your account from one CSS to another. This migration is only possible if both CSSs consent.
Ask your new CSS to contact Google support to request the migration. A Merchant Center account can only be associated with one CSS at a time.
Google Ads accounts do not need to be migrated. Your Merchant Center account determines which CSS your ads and free listings are associated with. When a campaign in any Google Ads account uses product data from a Merchant Center account associated with a specific CSS, that campaign is considered to belong to that CSS.
Tips for moving a Merchant Center account from Google Shopping to another CSS
Before you migrate, check two areas that often cause surprises after the switch.
Ads on Display remarketing and surfaces beyond general search
If the CSS you migrate to has not opted in to serving ads on Display remarketing or surfaces beyond general search, your ads will only appear on Google general search results pages. They will stop serving on other surfaces.
Product data for countries where the CSS program is not available
If the migrated Merchant Center account contains product data for countries where the CSS program is not available, ads and free listings for those countries may stop serving if the new CSS has not chosen to place ads and free listings there.
To continue serving ads and free listings both in countries where the CSS program is available and in countries where it is not, you have two options:
- Create a new Merchant Center account with Google Shopping for your product data in countries where the CSS program is not available.
- Use separate Merchant Center accounts for different country groups. For example, migrate or create an account with the new CSS for countries where the CSS program is available, and keep a Google Shopping Merchant Center account for countries where the CSS program is not available.
Migration setup options
When migrating a Merchant Center account from one CSS to another, two setup options are available.
1. Migration as a sub-account of the CSS's multi-client account
The account can be migrated as a sub-account of the CSS's multi-client account. In this setup, the CSS automatically receives access to your account.
The CSS associated with the multi-client account and the CSS associated with the sub-account must be the same.
2. Migration as a stand-alone account
The account can also be migrated as a stand-alone Merchant Center account. In this setup, the CSS does not automatically receive access to your account.
CSS staff must be added manually as users in the Merchant Center account.
