Click-to-expand ads are a type of expandable ad that can expand to a large size (up to 728x270 pixels). When a user chooses to engage with a click-to-expand ad (i.e., by clicking the ad) the ad then expands to the center of your page. Once the ad is expanded, a translucent layer grays out the background of your page, giving the user a near full-screen ad experience.
Click-to-expand ads are served as third-party ads and are created by Google-certified rich media vendors for the top display advertisers in our network. As with other Google ads, you earn based on whether the expandable ads on your site are priced on a cost-per-click (CPC) or cost-per-impression (CPM) basis. Keep in mind that you'll 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.
