As you already know, Rich Media ads can help you deliver an interactive ad experience to the users. Google Ad Manager has ‘Studio’ to enable publishers like you to create, preview, test, and run rich media creatives.
Studio is a tool that helps you to create and send rich media ad creatives to your clients directly. It has two parts:
a. Google Web Designer and the Studio SDK:
With Google Web Designer, you can just drag-and-drop the rich media components you would like to have in the creative. For instance, if you want to play a video inside a banner, you can drag a video component rather than coding it from scratch.
b. Studio Web UI:
Sudio Web UI is a workflow tool. You can use it to preview and test your rich media creatives, publish them for QA, and send them to the advertiser’s ad server for trafficking. More on Google Ad Manager Help documentation.
You can also use creative templates and then upload your creatives to convert the template into the actual rich media ad. For instance, you can buy a template and then fill the template with the right images/videos, Click-through URL, ad unit size, etc.
