🎯 Three Separate Instagram Algorithms

Instagram no longer uses a single algorithm.

Meta has officially confirmed that each part of the application —

Reels, Stories, and Feed —

has its own ranking system, tailored to the way users interact with content.

.

📊 Why Three Algorithms?

Each format has a different purpose:

• ✅ Reels Algorithm: for attracting NEW users (discovery). Works like TikTok — shows content to people who don't know you
• ✅ Stories Algorithm: for CONNECTING with the current audience. Private communication with subscribers
• ✅ Feed Algorithm: for EXISTING subscribers. Shows posts to people who already follow you

👉 Example: your Reels might get 100K views from strangers, Stories will be seen by 15% of subscribers, and a post in the Feed — by 8% of the most active followers.

⚡ Important: the content strategy must take into account all three algorithms. You can't grow only on Reels and ignore Stories — you'll lose touch with the audience. Read more about the general principles of social networks in our guide Social Media Algorithms 2025.

✅ Quick Conclusion: understanding the three algorithms is the foundation of success on Instagram in 2025. Each format requires a separate strategy.

📈 Reels Algorithm in Detail

Reels are the most powerful tool for growth on Instagram in 2025. The algorithm works as aggressively as possible to identify viral content.

🔥 Hierarchy of Metrics: What's Most Important

Meta has officially confirmed the priority of metrics for Reels:

• ✅ Shares (reposts): highest priority. If people are forwarding — the content is valuable
• ✅ Saves: second most important. Indicator of usefulness
• ✅ Comments: high weight, especially if the dialogue is active
• ✅ Likes: least weight. Needed for overall engagement
• ✅ Watch time: critically important. Watching to the end = quality content
• ✅ Replays: Instagram loves this. Sign of virality

⏰ The First 90 Minutes — A Critical Window

The Reels algorithm works in three stages:

Stage 1: Testing (0-30 minutes)

• Reels are shown to a small test group (500-1000 users)
• The algorithm measures the engagement rate
• If ER > 10% — it moves to stage 2

Stage 2: Expansion (30-90 minutes)

• The display is expanded to 5000-10000 users
• Shares, saves, and comments are evaluated
• High rates = entry into recommendations

Stage 3: Virality (after 90 minutes)

• Reels get into the top recommendations
• Reach grows exponentially
• Can get millions of views

👉 Practical Tip: publish Reels during peak activity hours of your audience. The first 30 minutes are crucial — you need quick engagement.

🎵 Audio and Trends

The choice of audio critically affects reach:

• ✅ Trending audio: music that is currently viral gives +30-50% to reach
• ✅ Original audio: if your audio becomes a trend — bonus in recommendations
• ✅ Popular sounds: audio with millions of uses — stable reach

⚡ Important: do not use copyrighted music without a license. Instagram may limit reach or delete Reels. If you are already familiar with TikTok algorithms, the principles are similar — more details in the article How the TikTok Algorithm Works in 2025.

✅ Quick Conclusion: the Reels algorithm prioritizes shares and watch time. The first 90 minutes are a critical window for virality. Trending audio gives a bonus to reach.

📱 Stories Algorithm: Display Mechanics

Why do only 15-20% of your subscribers see your Stories? The Stories algorithm works differently — it doesn't try to show everyone, but focuses on the most active audience.

👀 Who Sees Your Stories and in What Order

Instagram places Stories in the feed based on three factors:

• ✅ Frequency of Interaction: how often the user watches your Stories, likes, and replies
• ✅ Relationship signals: correspondence in Direct, comments under posts, mentions
• ✅ Publication Time: fresh Stories have priority

👉 Example of Display Order: if a subscriber watches your Stories and comments every day — you will be in the top three of their feed. If they haven't interacted for a month — you'll be at the end of the list.

🎯 Interactivity: How to Increase Stories Reach

Instagram loves interactive content in Stories. Use:

• ✅ Polls: the easiest way to get feedback. Engagement +40%
• ✅ Questions: open a dialogue with the audience
• ✅ Slider: another format of polls
• ✅ Quiz: game mechanics, high engagement
• ✅ Countdown: for announcements, creates anticipation
• ✅ Mention: involve other creators

🚫 Why Stories Don't Reach All Subscribers

Typical reasons for low Stories reach:

• ❌ Lack of Interaction: subscribers don't react — the algorithm reduces the display
• ❌ Rare Publication: you post once a week — you lose priority
• ❌ Monotonous Content: only promotional Stories — people skip
• ❌ Low Quality: blurry photos, poor lighting
• ❌ Only Static Images: video and interactive work better

⚡ Important: Stories have a lifespan of 24 hours, but the algorithm analyzes the speed of reaction. If there are many views in the first 2 hours — the display expands to less active subscribers.

✅ Quick Conclusion: Stories are not shown to all subscribers, but only to the most active. Interactivity and regularity are the keys to high reach.

⸻

🖼️ Feed Algorithm: Chronology vs Recommendations

In 2025, the Instagram Feed works in two modes, which the user can switch between:

📊 Two Types of Feed

• ✅ Following (chronological): posts from subscriptions in order of publication. Without algorithmic filtering
• ✅ For You (recommended): algorithmic feed with posts from subscriptions + recommended accounts

👉 Meta Statistics: 80% of users use the "For You" feed by default. Therefore, focus on algorithmic optimization.

💯 Engagement Rate and its Impact

For posts in the Feed, the main metric is Engagement Rate (ER):

ER Formula: (Likes + Comments + Saves + Shares) / Followers × 100%

• ✅ Excellent ER: > 5%
• ✅ Good ER: 3-5%
• ✅ Average ER: 1-3%
• ❌ Low ER: < 1%

🎯 What Affects Display in the Feed

• ✅ Speed of Reaction: the faster the engagement in the first 30 minutes — the more impressions
• ✅ Content Type: carousel (swipe posts) have a higher ER than single photos
• ✅ Saves: highest weight for the Feed algorithm
• ✅ Time in the App: the longer the user views the post — the higher the ranking

⚡ Important: posts in the Feed live longer than Reels. A quality post can receive engagement for 3-7 days after publication.

✅ Quick Conclusion: the Feed algorithm evaluates engagement rate and interaction time. Carousel posts and saves are the most effective formats for reach.

👥 Key Instagram Ranking Factors

Meta has officially confirmed three main signals that affect all Instagram algorithms:

🔗 Relationship

The strongest signal is the user's history of interaction with your profile:

• ✅ Does the user view your Stories regularly?
• ✅ Do they like, comment, and save your posts?
• ✅ Do they write in Direct?
• ✅ Do they mention you in Stories/posts?
• ✅ Do they visit your profile?

👉 Example: if a user watches your Stories every day and comments on posts — the algorithm classifies you as a "close person" to them. Your content will have the highest priority in their feed.

🎯 Interest (User Interests)

Instagram analyzes what content the user is interested in:

• ✅ What topics they search for
• ✅ What content they interact with the longest
• ✅ What accounts they view
• ✅ What Reels they watch to the end

The algorithm uses machine learning to predict interests and shows similar content.

⏰ Timeliness (Content Freshness)

Publication time is critical:

• ✅ Fresh content (0-2 hours) has the highest priority
• ✅ Posts older than 24 hours rarely get into the top of the feed
• ✅ Reels can go viral even a week after publication

⚡ Important: publish when your audience is online. Instagram Insights shows the peak activity hours of your subscribers.

✅ Quick Conclusion: the three pillars of ranking are interaction with the profile, relevance to user interests, and freshness of content. All other factors are secondary.

🚫 What Kills Reach on Instagram in 2025

❌ Top 5 Ways to Get Shadow Banned

• ❌ Reposts from TikTok with a watermark: Instagram actively reduces the reach of content with the logos of other platforms. Upload videos without a watermark
• ❌ Low Quality (blurry videos/photos): the algorithm automatically recognizes low-quality content and limits the display
• ❌ Clickbait Headlines: "YOU WON'T BELIEVE WHAT HAPPENED" — Instagram classifies as spam
• ❌ Buying Bots/Followers: the algorithm detects fake accounts and lowers your trust score
• ❌ Spam Activity: 100+ likes per minute, mass subscriptions — instant shadow ban

⚠️ Other Factors That Reduce Reach

• ❌ Using banned hashtags
• ❌ Excessive use of the same hashtags (#follow4follow, #like4like)
• ❌ Publishing politically sensitive or controversial content without context
• ❌ Too frequent publications (5+ Reels per day)
• ❌ Reposts of someone else's content without adding value

✅ Quick Conclusion: Instagram 2025 harshly punishes for low quality, reposts with watermarks, and spam activity. Focus on original, high-quality content.

💡 Strategies for Growth on Instagram in 2025

🚀 Universal Growth Formula

1. Reels to Attract New Users (60% Effort)

• Publish 3-5 Reels per week
• Use trending audio and formats
• Hook in the first 3 seconds is mandatory
• Length of 7-15 seconds — optimum for watch time

2. Stories for Retention (30% Effort)

• 4-6 Stories daily
• Minimum 2 interactive (polls, questions)
• Behind the scenes, personal moments
• Reply to all Direct messages — this strengthens the relationship

3. Feed Posts for Trust (10% Effort)

• 2-3 posts per week
• Carousel posts (swipe) have the highest ER
• Educational content, case studies, tutorials
• Long descriptions (1500-2000 characters) — Instagram appreciates this

📈 Tactics for Rapid Growth

1. Collaboration Reels — Double Reach

Joint Reels (Collab) are the most powerful tool of 2025. When you publish Collab Reels:

• ✅ The video appears in both profiles simultaneously
• ✅ Reach = your audience + partner's audience
• ✅ Engagement is counted for both accounts
• ✅ The algorithm perceives this as a signal of quality (two creators have approved the content)

👉 How to Find Partners: look for creators with similar topics and audience size (±30% of yours). For example, if you have 10K followers, collaborate with accounts with 7K-15K. This way, both sides will get the maximum benefit.

2. Series Content — Audience Retention

Serial content forces the algorithm to show all parts of the series:

• ✅ Format "Part 1/5": users are waiting for the next episodes
• ✅ Daily Challenges: "Day 1 of 30" creates a habit of returning
• ✅ Educational Series: "Lesson 1: Basics", "Lesson 2: Practice", etc.
• ✅ Storytelling: a story divided into episodes

👉 Secret: Instagram recognizes content series and automatically recommends previous/next parts in the "Related" section. This increases the total time spent by the user on your profile.

3. Engagement Pods — With Caution

Engagement pods (mutual support groups) are a gray area of Instagram:

• ✅ How it Works: 5-10 creators agree to like/comment on each other's content in the first 30 minutes after publication
• ✅ Advantages: quick initial engagement gives the algorithm a signal about quality
• ⚠️ Risks: Instagram may recognize unnatural activity and reduce reach

Rules for Safe Use of Pods:

• Group of no more than 10 people
• All participants from your niche (similar topic)
• Comments should be meaningful (minimum 5-7 words), not just "cool 🔥"
• Not every post — maximum 3-4 per week
• Activity should look natural (intervals between likes)

⚡ Alternative to Pods: create a Telegram/Discord community from your niche, where creators share content and organically support each other. This is safer and creates real connections.

4. Cross-Promotion — Synergy of Formats

Each format strengthens the other with the right strategy:

• ✅ Reels → Stories: published a Reel? Share it in Stories with a call to action "Watch the full version in Reels"
• ✅ Stories → Feed: announce a new post in Stories 1-2 hours before publication. Creates anticipation
• ✅ Feed → Reels: make a short Reels teaser for a detailed Feed post
• ✅ Behind the Scenes: show the process of creating Reels in Stories — people are interested in "how it's made"

👉 Example of Cross-Promotion:

1. Morning: Stories with the announcement "Today at 12:00 a new Reel about..."
2. 12:00: Publication of the Reel
3. After 30 minutes: Stories "Did you watch my new Reel? Here's what was left behind the scenes"
4. Evening: Stories with a poll "Which topic to cover in more detail in the next Feed post?"
5. Next day: Feed post based on the poll results

5. Bonus Growth Tactics

• ✅ Using Trending Sounds BEFORE the Peak: find audio that is just gaining popularity (10K-50K uses). Catch the beginning of the wave
• ✅ Reply via Reels: when someone comments on your post — reply via Reels. This creates two-way content and strengthens the connection
• ✅ User Generated Content: encourage subscribers to create content with your product/brand and repost in Stories
• ✅ Giveaways with Smart Mechanics: not "like + repost", but creative tasks (create Reels, share a story). Attracts an active audience
• ✅ Niche Hashtags: instead of #instagood (1B posts) use #webdevtips (50K posts) — higher probability of getting into the top

🎯 Content Mix Strategy 2025

Optimal distribution of effort for maximum growth:

⚡ Important: the most effective strategy of 2025 is not just "posting more Reels". It's an ecosystem: Reels attract new users → Stories retain and build relationships → Feed posts establish expertise → Collaboration expands reach → Series creates a habit of returning.

✅ Quick Conclusion: Collaboration Reels double reach, content series create a habit of returning, cross-promotion synchronizes all formats. The 60-30-10 tactic (Reels-Stories-Feed) is a basic formula, and real growth comes from combining all the tools into a single strategy.

🔧 Instagram Insights: What Metrics to Analyze

📊 Key Metrics to Track

For Reels:

• ✅ Reach: how many unique users saw it
• ✅ Plays: total number of views
• ✅ Accounts reached: % of new audience vs subscribers
• ✅ Shares: the most important metric for virality
• ✅ Saves: indicator of content value
• ✅ Average watch time: how many seconds they watch

For Stories:

• ✅ Impressions: number of displays
• ✅ Reach: how many unique users
• ✅ Exits: how many people closed your Stories (the less — the better)
• ✅ Replies: number of replies in Direct
• ✅ Sticker taps: interaction with polls and stickers

For Feed Posts:

• ✅ Engagement Rate: the main metric
• ✅ Saves: critically important for ranking
• ✅ Profile visits: how many people went to the profile
• ✅ Follows: how many subscribed after viewing the post

🎯 Benchmark Metrics 2025

🔍 Is There a "Best Time" to Publish?

Yes, but it is individual for each profile. Check Instagram Insights → Audience → Most Active Times. General statistics for Ukraine: weekdays 12:00-14:00 and 19:00-21:00, weekends 10:00-12:00 and 20:00-22:00. But your audience may differ.

🔍 How Many Hashtags to Use in 2025?

Instagram officially recommends 3-5 relevant hashtags. A maximum of 30 hashtags no longer gives advantages and may look like spam. Focus on quality, not quantity. Use niche hashtags with 10K-100K posts instead of millions.

🔍 Do Hashtags Affect Reels?

Minimally. For Reels, the main factors are content quality, trending audio, and engagement. Hashtags work more for Feed posts. For Reels, 2-3 relevant hashtags in the description are enough.

🔍 What is a Shadow Ban and How to Avoid It?

A shadow ban is an unofficial restriction of reach, when your content is not shown in recommendations and hashtags. Reasons: spam activity, use of banned hashtags, reposts with watermarks, buying followers. Avoid automation, mass actions, and low-quality content.

🔍 Should I Delete Posts with Low Reach?

No
