The current world’s top search engine (Google) is excited to introduce Adsense users expandable ads, a new type of ad that can appear on webmaster’s pages. Expandable ads are rich media ads that can expand beyond the original size of the ad unit, following a user-initiated action.
This creates more real estate for the ad, allowing for more interaction from interested users. For instance, expandable ads may stream a movie trailer, show video game clips, or display various views of an item for sale.
Just like other Google ads, the earning is based on whether the expandable ads on webmaster’s site are priced on a cost-per-click (CPC) or cost-per-impression (CPM) basis.
Webmaster will generate earnings from CPC expandable ads when a user visits the advertiser’s landing page, and not when a user simply clicks to expand the ad.
In order to protect the publisher and user experience, Adsense has created several policies around how expandable ads work. Ads will expand only after a user clicks and interacts with the ad. Mouseovers or rollovers won’t trigger the ad, in order to prevent accidental expansions. An expandable ad won’t expand more than double its width or height. Once expanded, the ad will appear as a layer over the page content so that your content will not be modified or shifted in any way. The user may close the expanded panel at any time.
According to Adsense Blog, the expandable ads are only available to specific advertisers located in the U.S currently, but Adsense will expand this feature reach to international soon.
