In more detail
FOMO works because people hate losing access more than they like gaining something new. Marketers trigger it with limited-time offers, low-stock alerts, countdown timers, "last chance" wording, and content that shows other people already in on the thing. Used well, it nudges hesitant followers to comment, click, or buy. Used too often, it reads as manipulative and burns trust, so the urgency has to be real. Fake countdowns and made-up scarcity get noticed fast.
Example
A skincare brand posts a Story: "Only 50 kits left, restock not planned until autumn." The scarcity is genuine, so people who were on the fence check out that day instead of forgetting by next week. Adding a countdown sticker can lift click-through on that post, but only if the deadline is true.
