Reels and carousels both work well, but they serve different purposes. Reels attract attention quickly because they move and play sound, which keeps people watching. Carousels are better for sharing step-by-step ideas or stories that need more space. If your goal is to grow fast, reels usually reach more people, but carousels help you connect deeper with those already following you. A mix of both keeps your page interesting and balanced. You can even turn one idea into both formats to test what performs best. Which format do you think makes people engage more with your posts?
