The Facebook collection ad is one of the newest on Facebook. This is a different advertising format than what you can find on social networks.
From a mechanical point of view: an additional click is necessary to trigger it. Concretely, the advertisement is presented as a static advertisement in the newsfeed, with a catchphrase, a visual. The only difference is in the lower part of the advertisement, which does not offer a button but an arrow prompting to click to deploy the instant experience. Once a user clicks on the call advertisement, they access a sort of full screen mini-site.
