What are Interstitial Ads?

Interstitial Ads are forms of advertisements that are inserted into the user experience of websites, apps, games, etc. These ads are commonly full screen ads, placed in between interactions of a website or app. For example, if you are on a news website and click on an article while viewing the homepage, an interstitial ad would be a full screen ad that may be featured for a certain amount of time before you view the article you have just clicked on.
