There isn’t one Instagram algorithm. There are several, and each is trying to predict something different.
How the Instagram algorithm works, explained for businesses
Instagram has explained publicly that Feed, Stories, Reels and Explore each use their own ranking systems, built to predict how likely a person is to engage with a piece of content. Understanding what each predicts is more useful than chasing posting-time hacks.

How does the Instagram algorithm decide who sees my post?
For each person and surface, Instagram predicts how likely they are to take actions such as watching, liking, sharing, saving or commenting, then ranks content by those predictions. Signals include what the person usually engages with, information about the post, and their history with your account. For Reels shown to non-followers, Instagram has emphasised watch time and shares.
What each surface is trying to predict
| Surface | Mainly shows | Signals that matter most |
|---|---|---|
| Feed | Accounts you follow, plus suggestions | Past interaction with the account, likes, comments, saves |
| Stories | Accounts you’re closest to | Viewing history, replies, closeness |
| Reels | Mostly accounts you don’t follow | Watch time, shares, likes relative to reach |
| Explore | Discovery based on interests | Engagement with similar content, post popularity |
What businesses can do
- Hook in the first seconds
- If viewers leave early, Reels struggle to reach beyond followers.
- Make content worth sending
- Shares by direct message are a strong signal of value. Practical tips and relatable moments get sent.
- Post original content
- Instagram has said it favours original content over reposts.
- Use Trial Reels to test
- Where available, test a Reel with non-followers before showing it to your audience.
- Measure DMs and bookings
- Reach isn’t revenue. Track which posts start conversations.
Story: same topic, two edits
Illustrative scenario, not a client case study.
A clinic films a two-minute explanation of a common treatment question.
Version one opens with the logo and a slow introduction; most viewers scroll away in the first seconds.
Version two opens with the patient’s question on screen and the doctor answering immediately, cut to 40 seconds.
Version two is shared by message far more often, and reaches people who don’t follow the clinic.
Same doctor, same topic, same day. The edit decided the reach.
Frequently asked questions
Do hashtags still matter?
They help Instagram understand topic but are a minor factor. Clear captions and on-screen text do more.
Is there a best time to post?
Posting when your audience is active helps early engagement, but content quality outweighs timing.
