The way this is described is kind of confusing, especially since "dark posting" isn't really a thing anymore (i.e. unpublished posts are simply just ads). Basically how the manual process works:<p>1. Post several ads (which will show up in people's newsfeed's along with their friend's updates, Page post, etc) that mimics the exact phrase and imagery that you would otherwise put in your Page post.<p>2. Create like 5-10 of them with different creative, verbiage, etc.<p>3. Whichever ad gets the most engagement, you copy that ad to a Facebook post which does show up in a Page feed (and if you're lucky in people's newsfeeds). Hope it goes viral and you'll end up with clicks to your content.<p>Unless you have viral headlining and content ("30 things these 6 girls never thought was possible until now") this won't be that useful, as the cost/benefit of it probably isn't worth it.
