INSTAGRAM ALGORITHM 2025: WHAT WORKS.

The Instagram algorithm has changed more in the last 12 months than in the previous 3 years combined. Most of what worked in 2022 and 2023 is now irrelevant, or actively penalised. Here's what's actually working for the brand accounts we manage in 2025.

What the Algorithm Actually Optimises For

Instagram's algorithm has one goal: maximise time spent on the platform. Everything it does is in service of that. It shows content that it predicts will hold attention and drive engagement, and it measures this at the individual user level. Your content isn't competing against all content; it's competing for each specific user's attention based on their past behaviour.

This means relevance beats reach. A highly targeted post that resonates deeply with 500 of the right people will outperform a broad post seen by 5,000 of the wrong ones.

Reels: Still King, But Different

Reels remain the highest-reach format on Instagram in 2025, but the algorithm has gotten smarter about what it pushes. Gone are the days when any Reel would get a boost. Now the key signals are:

• Watch-through rate: What percentage of viewers watch to the end? Hooks in the first 1-2 seconds are critical.
• Shares: Sends are the most powerful engagement signal in 2025. If someone shares your Reel to a friend's DMs, that's a massive positive signal.
• Saves: Still important, especially for educational content. A saved post says "I want to come back to this."
• Comments: Weighted more than likes but less than shares. Comment pods are now detected and penalised.

The 3-Type Content Framework

The brand accounts that are growing consistently in 2025 are using a three-type content rotation:

• Reach Content (40%): Educational or entertaining Reels designed to be shared and discovered by new audiences. These prioritise the hook and shareability over brand messaging.
• Engagement Content (30%): Posts, carousels, and conversational Reels that drive comments and saves from existing followers. These build community and signal account health.
• Conversion Content (30%): Direct product/service content, testimonials, offers, and call-to-actions. These are shown primarily to followers, people who already know you.

Posting Frequency in 2025

Consistency beats frequency. Three high-quality Reels per week dramatically outperforms seven mediocre ones. Instagram now explicitly evaluates content quality before distribution, posting low-quality content hurts your account health score and reduces reach on future posts.

"Post less. Make it better. Give people a reason to share it."

What's Actively Hurting Reach

• Posting downloaded videos with visible TikTok watermarks
• Using banned or overused hashtags as a main growth strategy
• Deleting and reposting content (now tracked and penalised)
• Inconsistent posting patterns (going dark for weeks, then posting daily)
• Low-quality vertical video with poor lighting or audio

The Hashtag Question

Hashtags are now a secondary discovery tool at best. Instagram's own internal data shows that the majority of Reels discovery comes from the Explore algorithm and Suggested Posts, not hashtags. Use 3-5 relevant hashtags, not 30. And focus on niche hashtags (under 500k posts) rather than mass hashtags.

What's Working Right Now

For brand accounts specifically, the highest performing content in our client portfolio in early 2025: authentic behind-the-scenes content, founder stories, customer transformation posts, and educational content that solves a specific problem for a specific person. Not aesthetic product shots. Not promotional carousels. Real stories told in a relatable way.
