Google Shopping ads show people the products you are selling including photos of your product, a title, price, store name and more. These ads can be used to promote your online and local inventory, boost traffic to your website or local store, and find better qualified leads.
Google Shopping ads are displayed on the top or on the upper right side of the search results when a user searches for a product on Google.
Google Shopping works together with the Merchant Center. The Merchant Center is a tool which allows you to upload and maintain your store information, brand and product data including pictures and pricing. Based on the data in your Merchant Center, Google Shopping will use this information and display the data in your ads and other relevant Google services.
Google Shopping ads use your Merchant Center product data – not keywords – to decide how and where to show your ads. This is why the click-through rate (CTR) for Google Shopping is highly dependent on both the specific product and its attributes that are defined in your Merchant Center.
