This common ad type can be placed above content in your site’s header, mid-content, or below content in the footer of your site. On Desktop, this ad is sized at 728×90, and on Mobile, it is sized at 320×50, which is the highest-performing mobile-specific ad size.
To increase the profitability of mobile we can also convert the ad into a Mobile Header In-Screen which means it will stick indefinitely as the user scrolls which increases viewability.
