You may have used our original expander to add action and appeal to advertisers’ Xspots.

When a standard 300×250 display ad is set to expand, a viewer’s click or mouseover resizes the ad to 560×300. You can fill the 300×250 space to the left of the Xspot with a widescreen version of the video, an image, or a message.

Visit our Gallery to interact with a variety of expanding Xspots.

On the Google content network and other publisher websites, you commonly see a couple of other expander sizes:

• 600×250
• 500×300

With our latest release of the Mixpo platform, you can now set 300×250 Xspots to expand to both of these sizes. As with the original expander, you can fill the expanded space with a widescreen version of the video or add an image or message.
