So I was having a heck of a time getting my "make money online" ad approved by FB. Sometime it gets approved, other times it gets disapproved. And when you are trying to test headlines for conversions, it can be very frustrating to edit an already approved ad only to get it disapproved later. Here's my "solution" - create a post with a mild, informative headline. Place an ad for "post engagement" for this post. The mild headline will appear in your FB ad near the top of the ad, almost like a sub title underneath your page's official title. This mild headline will not have a good ctr for obvious reasons. But the good news is when your ad is approved, you can edit the description of that post any time and your new content in that post will appear in the ad without any need for further review again! Which means you can change the content of your ad, put a link to your external website,etc, and your new content will appear in your ad live.
