Studio is a workflow tool for managing your rich media ads. After you've built your creatives, you can upload them into Studio, preview them, test that they work correctly, send preview links, publish them for QA, and send them to your client's Campaign Manager 360 or Google Ad Manager account so they can be sent live to show on websites.
This guide walks you through the process of uploading the creatives you've built to Studio.
If you're building creatives with Google Web Designer, save time by publishing creatives directly from Google Web Designer into Studio.
