How does Google Merchant Center interact with Google Ads?

Google Merchant Center works with Google Ads to display your product listings as Shopping ads. The Merchant Center houses your product data, which Google Ads uses to generate targeted ads across Google’s network.

• Google Ads passes inventory data to Google Merchant Center so advertisers can use the data to build a Shopping campaign.
• Google Ads passes campaign performance to Google Merchant Center so advertisers can use the data to influence future campaign builds.

Explanation:
Google Merchant Center acts as the bridge between your product inventory and Google Ads. You upload your product data—such as images, pricing, and descriptions—into Merchant Center. Google Ads then pulls this data to create and show Shopping ads across Search, YouTube, Gmail, and the Display Network. The synchronization between Merchant Center and Google Ads ensures that your ads are accurate, up-to-date, and optimized for relevant search queries. This interaction allows advertisers to run product-focused campaigns that directly reflect their online inventory.
