"The algorithm" gets blamed for a lot. Views drop, and business owners assume Instagram is punishing them. Views rise, and they assume they cracked a secret code. The reality is more useful and less mysterious.
Instagram has been fairly open about how it ranks content, mainly through its head, Adam Mosseri, and its official creator and business resources. This guide summarises what Instagram has said publicly, what we see in practice with business accounts in India, and what you should actually do about it. We have avoided made-up statistics; where something is our experience rather than Instagram's statement, we say so.
There is no single algorithm
Instagram has explained that it uses different ranking systems for different parts of the app, because people use each part differently:
- Feed: mostly posts from accounts you follow, plus some recommendations.
- Stories: mostly from accounts you follow, ordered by how likely you are to view them.
- Reels: largely recommendations from accounts you do not follow, ranked by how likely you are to enjoy them.
- Explore: recommendations based on your interests, from accounts you mostly do not follow.
- Search: results based on your search terms, account names, captions and other information.
Each system predicts how likely a person is to take certain actions on a piece of content, and shows what it thinks they will find most valuable.
The signals Instagram has highlighted
Instagram has publicly described several kinds of signals it uses:
- Your activity: what you like, share, save, comment on and watch.
- Information about the post: how popular it is, how quickly people engage with it, and details like when it was posted, the topic and the length of a video.
- Information about the account that posted: how often people interact with it.
- Your history with the account: whether you regularly engage with its content.
Mosseri has said that, for reaching people, three of the most important signals are watch time, sends per reach (how often people share the content in DMs) and likes per reach. Sends tend to matter most for reaching new audiences, while likes matter more for reaching existing followers.
What this means for business content
Watch time is king for reels
If people watch your reel to the end, and especially if they rewatch it, Instagram reads that as a strong signal. That means:
- Hook in the first seconds. If the start is slow, people swipe away. See reel hooks that work.
- Cut ruthlessly. Remove pauses, repetition and slow intros.
- Match length to content. Instagram now allows reels up to three minutes, but a reel should only be as long as it needs to be.
Sends are the strongest growth signal
Content that people share with friends is shown to more new people. For businesses, shareable content includes:
- Useful tips and checklists
- Relatable everyday situations
- Local content people want to show friends ("we have to go here")
- Offers worth telling someone about
Ask yourself before posting: "Who would someone send this to, and why?"
Likes still matter, mainly with followers
Likes relative to reach help your content perform with existing followers. Good-looking, relevant posts that your followers appreciate keep your account healthy.
Originality is rewarded
Instagram has said it favours original content and reduces recommendations for accounts that mostly repost content made by others. It has also said it will replace reposted versions with the original in recommendations where it can identify them.
For businesses, that means:
- Make your own content, even if it is simple.
- Do not repost other accounts' videos as your own.
- Avoid posting videos with visible watermarks from other platforms; Instagram has indicated these are less likely to be recommended.
Trial reels let you experiment
Instagram introduced trial reels, which are shown first to people who do not follow you. You can see how a trial performs before deciding whether to share it with your followers. This is useful for testing different hooks or formats without worrying about putting off your existing audience. Availability can vary by account type.
Recommendations have rules
Instagram has published recommendation guidelines. Content that breaks its rules, or is considered low quality or sensitive, may not be recommended to non-followers, even if it stays on your profile. If your reach to non-followers suddenly drops, check your account status in the app's settings, which shows whether your content is eligible for recommendations.
Search: help Instagram understand you
Instagram search uses your account name, username, bio, captions, hashtags and location tags. For businesses:
- Put what you do and where you are in your name field and bio, such as "Sharma Sweets | Mithai & Namkeen, Modinagar".
- Write descriptive captions with words people would search for.
- Tag your location.
- Use a few relevant hashtags rather than long lists. Mosseri has said hashtags are not a major driver of reach; their main use is helping categorise content.
What does not work
- Buying followers or engagement. Fake accounts do not watch, share or buy. They can also hurt how your content is distributed to real people.
- Engagement pods where accounts like each other's posts. Instagram treats inauthentic engagement as against its rules.
- Posting the same content repeatedly.
- Deleting and reposting content that did not perform well, hoping for a better result.
- Chasing every trend with content unrelated to your business.
Posting frequency and timing
Instagram has said posting more often can help you reach more people, but quality matters, and posting low-quality content just to keep up does not help. In our experience with business accounts, two to four posts a week with at least one or two reels is a sustainable rhythm for most small businesses.
Timing matters less than it used to, because content is shown over time and to people who do not follow you. Check your account's insights to see when your followers are most active, and post around then.
Use Insights, not guesswork
Your professional dashboard shows:
- Reach, split between followers and non-followers
- Watch time and how many people watched to the end (for reels)
- Shares, saves, likes and comments
- Profile visits and link taps
- Follower growth and audience location
Every month, look at your best and worst content and ask what was different. Over time, the patterns for your audience become clear.
A simple checklist before you post a reel
- Does the first second make someone stop?
- Is every second necessary?
- Are there captions on screen?
- Is it original, with no other platform's watermark?
- Would someone send it to a friend?
- Does the caption describe what it is, with the location?
- Is there a clear next step?

Frequently asked questions
Does the Instagram algorithm favour reels over photos?
Reels are the main format Instagram uses to recommend content to non-followers, so they usually reach more new people. Photos and carousels still perform well with existing followers.
Do hashtags help reach on Instagram?
They help Instagram understand what your content is about, but they are not a major driver of reach. Use a few relevant hashtags along with descriptive captions and location tags.
Why did my reach suddenly drop?
Common reasons include less engaging content, slower hooks, posting less often or content that is not eligible for recommendations. Check your account status in settings and compare recent posts with your best performers.
When should a business post on Instagram?
Check your Insights to see when your audience is most active. Timing matters less than content quality, because Instagram shows content over time and to non-followers.
Should I delete posts that perform badly?
Generally no. Deleting and reposting does not reliably improve reach. Learn from the post and improve the next one.
