Instagram Algorithm: Complete Breakdown
Learn how the Instagram algorithm works for Reels, Feed, and Stories. Understand ranking factors and optimize your content for maximum reach.
Instagram actually uses multiple algorithms—one each for Feed, Stories, Explore, and Reels. Each has different ranking factors. Understanding these differences is key to maximizing your reach across the platform.
Instagram Reels Algorithm
The Reels algorithm is designed to surface entertaining content to users who might not follow you yet. It's your best growth tool on Instagram.
- Watch time and completion rate
- Audio page visits (using trending sounds)
- Engagement rate (likes, comments, shares, saves)
- Content relevance to viewer interests
- Profile interactions after viewing
Pro Tip: Use ViralNow to analyze your Reels before posting and optimize for these exact metrics.
Feed Algorithm
The Feed algorithm primarily shows content from accounts you follow, ranked by predicted interest and relationship.
- Relationship with the poster (past interactions)
- Interest prediction based on past behavior
- Timeliness of the post
- Content type preferences
- Session duration consideration
Stories Algorithm
Stories appear in order based on whose Stories you engage with most, with recent posts from close connections prioritized.
- How often you view someone's Stories
- DM history with the account
- Relationship closeness signals
- Recency of the Story
Explore Algorithm
Explore shows content from accounts you don't follow, based on your interests and engagement patterns.
- Similar to content you've engaged with
- Popular with users like you
- Trending or rapidly growing content
- Category and topic matching
Shadowbanning and Reach Drops
Instagram can limit reach for content that violates guidelines or appears spammy.
- Avoid banned hashtags
- Don't use automation tools
- Stay within community guidelines
- Avoid repetitive posting patterns
- Original content performs better than reposts
Frequently Asked Questions
Why is my Instagram reach suddenly low?
Common causes include: algorithm changes, posting at suboptimal times, using problematic hashtags, or a shift in your content that doesn't match audience expectations.
Does Instagram favor Reels over photos?
Instagram has stated they prioritize all content types equally, but Reels currently offer more discovery potential since they're shown to non-followers on the Reels tab and Explore.
How do I reset my Instagram algorithm?
You can influence your Explore by using 'Not Interested' on content you don't want, clearing search history, and actively engaging with content you want to see more of.
