A social media post that is represented to be an ad aimed at a specific demographic is referred to as a dark post while it remains unpublished. It does not appear on the timeline of the entity it has been created to represent and it is unavailable organically. These types of posts are useful in split-testing. They also protect your timeline from an onslaught of unwanted promotional posts. The term itself gives the content a vibe of undercover secrecy, however, this is not actually the case since it is now possible for anyone to utilize the Page Transparency feature on Facebook to view all of your Facebook ads.
