If you host your in-stream video ads on an ad server other than Display & Video 360 or Campaign Manager 360, you can add them to Display & Video 360.
Before you get started, you'll need VAST (Video Ad Serving Template) tags for the ads. Display & Video 360 supports VAST 2.0, 3.0, and 4.0 tags.
Add a new third-party video creative and paste in the VAST tag URL.
After you add tags, Display & Video 360 automatically wraps them with an impression tracking macro and a click tracking macro. With these macros, you can view the number of impressions, clicks, and conversions for the creative in Display & Video 360.
Add a third-party in-stream video tag
Follow these steps to upload one tag. If you need to upload more than one tag, save time with bulk upload.
Open an advertiser, then click Creatives in the left menu.
On the page that loads, click New.
Click Third party Third-party video.
Enter a name for the creative.
Enter the VAST tag URL. It can be up to 1,024 characters long.
(Optional) Click Additional details to add an integration code or notes.
Save your creative.
After you save, it’ll take a few minutes for Display & Video 360 to process the video and detect the duration, whether it has a skip button, supported video technologies, and whether it has companions. When processing is complete, you can preview your video.
