Expandable ads are a premium online advertising unit. While the traditional banner ad clicks directly to your landing page, think of an Expandable Ad as an "in-between" where you first ask a consumer to open your ad to learn more. Once the ad is opened, you may feature larger graphics and videos across multiple pages of the ad. The ad is able to click through to any number of URLs you need to use. Like the ad, reporting is robust providing you a layer of additional information such as how many people opened your ad, how long it remained opened, and hoe many videos were streamed.
