Can No Button Convert a Facebook Ad?

You can choose no button as you're called to action. That gives mou more headline space because you can put a bigger headline in there. And also, it might look a little less like an ad because it doesn't have the button. Can we use shapes, like arrows and stuff that, or moges inside the images? What your thoughts on that? Arrows no longer. facebook has been coming down very hard on accounts that use arrows.
