The carousel that made people stop and swipe outperformed my only Reel by nearly three times, share for share. Not because video is wrong, but because a carousel gives someone a reason to pause on slide two, and a reason to send it to someone by slide six.

The difference is not the format. It is whether there is a reason to act once they have seen it.

Three questions before choosing a format

Is this a single moment, or a structure someone can use? A structure belongs in a carousel.

Does it need a reason to share, not just a reason to watch? Shares are the only thing that buys you reach you did not already have.

Would the last slide work as a message someone forwards to a friend? If not, it is not finished yet.
