The number that matters in stories is retention: how many people who saw your first frame were still there at your last. Everything else — taps, exits, replies — is detail explaining why that number went up or down.
The metrics, in plain words
Reach
How many people saw that frame. Compare the first and last frame of a sequence to get retention.
Forward taps
Someone tapped to skip ahead. A moderate number is completely normal — that is how people watch stories. A spike on one specific frame means that frame was not worth their time.
Back taps
Someone tapped back to see it again. Counter-intuitively this is one of your best signals: it means something was interesting enough to rewatch.
Exits
Someone left stories entirely at that frame. This is the one to take seriously. A high exit count on a particular frame tells you exactly where you lost people.
Replies
The strongest signal of all, and the rarest. A reply is a direct message — it tells Instagram you have a real relationship with that person, and it opens a 24-hour window in which you can respond.
How to actually read a story sequence
Line your frames up in order and look at reach going down the list. It always declines. What matters is where it declines sharply.
- A steady, gentle drop — normal. People have limited time.
- A cliff at one frame — that frame is the problem. Too long, too dull, or asking for something too early.
- A cliff at frame one — the opening does not earn attention, exactly as with a Reel.
What good retention looks like
If 70% or more of the people who saw your first frame reach your last, that is strong. Around half is normal. Below a third means the sequence is too long or the opening is not setting up a reason to continue.
Shorter sequences retain better. Five well-chosen frames almost always outperform fifteen.
Where stories fit in growth
Stories rarely bring new people. They are shown mostly to those who already follow you, which makes them a retention tool rather than a reach tool. Their real value is turning followers into people who reply, buy and stay — which is why asking people to send a keyword works especially well in stories.
If you want to reach new people, that is what Reels are for. Use stories to deepen what you already have.
