reels for growth, no contest, theyre the only format ig pushes to strangers right now, carousels barely leave your existing audience. but dont write carousels off, they do a job people skip: the reel gets you SEEN, the follow happens on the profile visit, and a strong carousel (or a pinned one) is what converts that visit because it shows depth + value in 3 seconds of swiping. so its reels to get discovered, a good carousel to close the follow. reels only + a weak profile = lots of views, no follows. is your profile actually set up to convert a reel-viewer who taps through, or is it just a feed of random posts?
