Uploaded Ads and Responsive Display Ad are the key ad formats to use in Google Display Ads campaigns.
Google Display Network allows users to create different formats of digital ads and customize them. There are two main ways to create display ads: uploaded and responsive. You can upload your custom ads or choose responsive ads to let Google automatically generate ads.
Custom uploaded ads are suitable for users who want to have maximum control over the creatives used in Display campaigns. They allow uploading image ads that aren’t created in Google Ads (For example, you can design them in Google Web Designer). Before choosing this option, make sure custom display ads fit in the selected spots.
Responsive display ads enable you to upload your assets (including logos, images, headlines, descriptions, and videos) to have ads automatically created based on them. Google automatically generates ads using the input to show them on the Google Display Network. Responsive display ads are considered a more convenient substitute for custom uploaded ads. Despite limiting your creative choices, they save a lot of time.
