Mobile Banner & Interstitial Ad Specs

We put limitations on our ad markup to ensure accurate display of quality ads every time on every device.

Ad developers should pay special attention to how their creatives function on different types of devices in both app and web platforms. Use the AOL Expo App to view your ads as they would appear on our SDK.

The Mobile Marketing Association (MMA) defined standard banner sizes that fit mobile devices. Whenever possible, the Marketplace includes device parameters in the bid request. This helps with targeting campaigns and getting compatible ad variations onto the right 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 has the right to restrict this list.

Text Only

A text ad is an XHTML snippet that produces clickable text. It’s typically written as <a href=”click link”>ad text</a> and often includes an image tag to retrieve a tracking pixel. Text ads are suitable for all mobile sites.


A banner ad is also an XHTML snippet but it produces a clickable image. It’s usually written as <a href=”click link”><img ...></a> and often includes an image tag to retrieve a tracking pixel. The <img…> element references the creative, specifies its height and width in pixels, and optional alternate text. Banner ads are suitable for almost all mobile sites.

JavaScript - MRAID

JavaScript is often used to create rich media ad experiences but is not as broadly supported across the mobile ecosystem as it is online. Be sure the site allows their use before serving JavaScript ads.

Several ONE by AOL: Mobile publishers support MRAID 2.0 to facilitate the delivery of Rich Media ads. See Industry Resources for more MRAID detail.

JavaScript - Generic

Generic JavaScript is supported for the delivery of basic banner ads. To facilitate rich media, see the JavaScript – MRAID section above.
