Facebook Reels can work well for CPA promotions if the content is short, catchy, and offers a clear benefit. Since Reels are mostly entertainment-focused, the best approach is to blend your offer into something that looks native to the platform. Quick demos, real-life uses, or problem-solution angles often get better engagement. You’ll also need to watch how strict Facebook is with your landing pages and ad content, especially if the offer is sensitive. If done right, Reels can bring in cheap views and help warm up the audience. What type of CPA offers do you think fit best with this format?
