Facebook Adverts allow advertisers to create their content in the ad console without displaying
it on their Facebook Page. These news feed ads that do not actually get published to the news feed of the advertiser’s Page, are
called dark or ghost posts.
Dark posts allow advertisers to run different ads as sponsored posts, targeting distinct consumer groups. They may split
test headlines and create personalized messages for different demographic and geographic targets, simultaneously running multiple
ads, one for each of the target group.
