Instagram’s algorithm has evolved dramatically in 2025, and understanding its latest updates is crucial for anyone looking to grow their presence on the platform. The good news? Instagram’s head Adam Mosseri recently revealed the exact ranking factors that matter most.

The Top 3 Ranking Signals That Actually Matter

The top three signals that matter most for ranking are watch time, likes and sends. Let’s break down each critical factor:

1. Watch Time: The King of All Metrics

Watch time is the #1 signal for both. If people don’t watch, your content won’t rank well. This means keeping your audience engaged throughout your entire video is more important than ever.

How to Maximize Watch Time:

• Hook viewers in the first 3 seconds with a compelling opener
• Use pattern interrupts – change scenes, angles, or visuals every 2-3 seconds
• Create curiosity gaps – promise valuable information that comes later
• End with a strong call-to-action to encourage rewatching
• Ensure all video content is cropped to 9:16. Videos should be anywhere from 30 seconds to 90 seconds

2. Likes Per Reach: Quality Over Quantity

It’s not just about total likes – Instagram now focuses on likes per reach, which measures how engaging your content is relative to how many people see it.

Content That Gets Liked:

• Behind-the-scenes content that shows personality
• Educational posts that provide clear value
• Relatable content that sparks emotional connection
• Visually stunning content that stops the scroll
• User-generated content and testimonials

3. Sends (Shares): The Ultimate Engagement Goal

When users share your content via DMs or to their Stories, it’s the strongest signal that your content resonates with your audience.

How to Create Shareable Content:

• Ask for shares directly – “Share this with someone who needs to see it”
• Create content with built-in sharing triggers – “Tag a friend who…”
• Use shareable formats – carousel posts, quote graphics, tutorials
• Leverage current events and trends for timely, relevant content

Platform-Specific Algorithm Strategies

Feed Algorithm

Algorithm ranking factors include how often users interact with your content, and a history of interacting with the person who posted plays a significant role.

Key Tactics:

• Respond to comments quickly to boost engagement velocity
• Create content that encourages meaningful comments
• Use 5-10 strategic hashtags (not all 30)
• Post consistently to maintain visibility

Stories Algorithm

Even without touching a like button, the time users spend viewing a Story will factor into the Instagram algorithm.

Optimization Tips:

• Use interactive stickers (polls, questions, quizzes)
• Create Stories series to encourage multiple views
• Share behind-the-scenes content that feels authentic
• Cross-promote your feed posts in Stories

Reels Algorithm

In 2025, every time a user watches a Reel, it adds to the view count. In the past, only the first view counted, while the following views were ignored.

Success Formula:

• Focus on entertainment value – even educational content should be engaging
• Use trending audio but make it relevant to your content
• Create content that demands multiple views
• Include strong hooks in the first few seconds

Advanced Strategy: Build Relationships, Not Just Followers

Don’t think the algorithm is working against you. It’s actually trying to connect you with what your current audience is interested in, or their past interactions.

Relationship Building Tactics:

• Engage authentically with your audience’s content
• Respond to every comment in the first hour after posting
• Use Instagram DMs strategically to build connections
• Create community-focused content that brings people together

Common Algorithm Mistakes to Avoid

1. Ignoring Community Guidelines – To succeed on Instagram in 2025, respecting community guidelines, creating original content, posting at optimal times, engaging with comments and DMs, using relevant hashtags, and adding location tags is important
2. Overusing Hashtags – Focus on 5-10 highly relevant hashtags
3. Posting at Wrong Times – Use Instagram Insights to identify when your audience is most active
4. Neglecting Engagement – The first hour after posting is crucial
5. Focusing Only on Follower Count – Engagement rate matters more than follower count

Your 2025 Action Plan

Week 1: Audit your Instagram Insights for watch time, likes per reach, and sends per reach Week 2: Optimize your content strategy around the three key ranking signals Week 3: Implement engagement strategies and respond to comments within the first hour Week 4: Test different content formats and posting times

The Bottom Line

Cracking Instagram’s algorithm in 2025 isn’t about gaming the system – it’s about understanding how to create content that genuinely serves your audience. By focusing on watch time, likes per reach, and sends while building authentic relationships, you’ll naturally align with what the algorithm rewards.

In 2025, the algorithm evaluates business and personal accounts the same way. Factors like content relevance, follower relationships, post timing, and engagement rates determine rankings.

Start implementing these strategies today, and watch as your Instagram presence grows organically throughout 2025. Remember: the algorithm is your friend when you focus on creating valuable, engaging content that your audience actually wants to see.
