Shopping ads
About Shopping ads
If you're a retailer, you can use Performance Max campaigns with a Google Merchant Center feed or Shopping campaigns to promote your online and local inventory, boost traffic to your website or local shop and find better qualified leads. To get started, you'll send us your product data with Merchant Center and create a campaign in Google Ads. Then, we'll use your campaign and product data to create ads on Google and in other placements around the web, depending on the campaign type. Shopping ads are one type of ad that can be created from your product data. In contrast to a text ad, which displays text only, Shopping ads show users a photo of your product, plus a title, price, shop name and more. These ads give users a strong sense of the product that you're selling before they click the ad, which gives you more qualified leads.
