If you don't see your ad on Facebook it might be that you have not checked Public post on the order page when ordering the campaign. Ads with public post will be displayed on your Facebook wall. The public post is simply a copy of the actual ad. The ad itself is displayed in the feed of the potential buyer.
If you want a copy of your ad posted on your Facebook wall, please contact firstname.lastname@example.org, and we will help you make the post public.
