The box ads directly above the site footer on most pages. This placement may be at the bottom of the page but it really shines on mobile, where the square(ish) shape takes up a much larger footprint than the billboard and banner ads, and visitors routinely scroll to the end.
The required dimensions (387×323) are expanded from a standard ad size (300×250), so if you already have artwork in those smaller dimensions and it is not possible for you to have it produced at the expanded size, we will upsample it for you. Ads in this placement rotate randomly on page load in groups of three with other ads purchased for the same time period, each weighted so that they receive equal display time. Impression, click and CTR tracking reports are available.
