Mobile Banner & Interstitial Ad Specs

To ensure quality ad delivery and display, markup limitations must be enforced. Ad developers should pay special attention to how their creatives appear and function on different types of devices in both app and web platforms.

The Mobile Marketing Association (MMA) defines standard banner sizes that can be selected to suit the device. To the extent possible, the Marketplace will include the device parameters in the bid request to assist with targeting campaigns or ad variations onto compatible devices.

ONE by AOL: Mobile currently supports the ad types described below. By default, any of these can be delivered in response to a bid request. However, the publisher may restrict this list based on knowledge of the type of ad they have used when building their site.

Text Only

A text ad is a valid XHTML snippet that produces clickable text. Typically written as <a href="click link">ad text</a> and often followed by an image tag to retrieve a tracking pixel. Text ads are suitable for all mobile sites


A banner ad is a valid XHTML snippet that produces a clickable image. Typically written as <a href="click link"> <img... /> </a> and often followed by an image tag to retrieve a tracking pixel. The <img…> element references the creative, specifies its height and width in pixels, and optionally specifies alternate text. Banner ads are suitable for almost all mobile sites.
