You need to link your Google Ads account and your Merchant Center account before you can create Shopping campaigns. After you link the accounts, you'll be able to create a campaign that uses your product information. Product data in Merchant Center can also be used to power other add-ons, like promotions and custom reports.
By linking your Google Ads and Merchant Center accounts, you’ll be able to connect your Google Ads account to your Business Manager, which will automatically link to all other connected apps in the Business Manager account. This extends the capabilities of your Google Ads account, allowing you to promote your products and local stores.
Note: Linking to Business Manager can also be initiated in Google Ads by going to
Tools 
, then
Data manager, and selecting “Google Merchant Center”, under “Featured products”.

Note: In countries where the Comparison Shopping Services (CSS) program is available, you participate in Shopping ads through one or several CSSs of your choice. Some CSSs manage your product data and your campaigns on your behalf, while others provide tools allowing you to manage your setup yourself.
