IAB Expanding HTML5 Ads


IAB Expanding HTML5 Ad

HTML5 Expanding IAB Ads are HTML5 ads in standard IAB Ad sizes that expand when clicked or tapped. Expandable Ads run in a majority of IAB Leaderboard and Medium Rectangle positions. The ad has a call to action prompting the visitor to tap or click, revealing additional panels below, above, to the left, or to the right of the original ad. When the visitor mouses off the ad or the expand times out, the panel collapses.

Note: The expansion of the ad and any audio components must be initiated by visitors.
