Responsive display ads are replacing responsive ads as the default ad type for the Display Network. They can be used in standard Display campaigns as well as Smart Display campaigns. To create a responsive display ad, upload your assets (images, headlines, logos, videos, and descriptions), and Google will automatically generate ads to be shown on the Google Display Network.
Optimize your ads: When you create a responsive display ad by uploading different assets into Google Ads, Google uses a machine learning model to determine the optimal combination of assets for each ad slot based on predictions built from your performance history.
Broader reach: Multiple assets can be uploaded per asset type (for example, multiple headlines, logos, videos, and images). The ads that Google assembles automatically adjust their size, appearance, and format to fit just about any available ad space. For example, a responsive display ad might show as a native banner ad on one site and a dynamic text ad on another.
