How to Add an Expanding Banner in Google Ad Manager

1. Open and log into the DoubleClick dashboard for your account. If you want to create a new campaign with the banner, click 'New Ad Unit.' If you want to change a current banner, click the ad and click 'Edit.'
2. Click the 'Browse' button in the New Creative section. Select your animated file, such as a Flash banner or GIF image that expands in the ad space. Click 'OK.' Type the click-through URL and click 'Save.'

3. Type the cost-per-click information in the next window. The cost is what you charge customers when a user clicks the ad. In the Price Priority text box, give a priority for the banner. If you get paid more for this banner, set it with a value of 1 so it will show more often.
4. Click 'Save' again to save the settings. Open the URL that contains the banner ad to verify that the ad expands and runs properly in the ad space.
