In its simplest form, an ad unit is a placeholder for an ad on a website or app. A publisher can have many ad units on a web page, each serving a specific range of ad types and ad sizes. An ad unit contains the ad code used to call ads from the ad server and serve it to users. Below is an example of a website on a mobile and desktop device showing different ad unit locations.
There are many different ad unit sizes available. Some perform better than others. Here are some of the best performing ad sizes for desktop and mobile devices as well as examples on web pages.
Desktop: 970×250, 970×90, 728×250, 728×90, 336×280, 300×250, 300×600, 160×600
Mobile: 320×50, 320×100, 300×250, 336×280
