So, you have this awesome picture that you posted to your Facebook post and you boosted it. Or maybe you created a new ad with that same awesome image. You submit it and get the awesome “Your ad has been approved” message. You think, “that’s cool”, and then go to bed. When you wake up ready to start the next day, you check your email and see “Your ad wasn’t approved – please edit and resubmit your ad”. You think “WTH Facebook?”
Enter Facebook’s 20 percent rule, where they say?your image can’t contain more than 20% text. The issue is that they use this “grid” system to automatically check images, so even though you may have less than 2o% text, you may still get dinged.
