The Instagram algorithm has become one of the most discussed topics in the social media world. With its continuous evolution, staying ahead of its changes is critical for social media managers, content creators, and brands striving for better engagement and visibility. By 2025, Instagram's algorithm has pivoted in ways that demand fresh strategies for optimizing your content. This deep-dive blog explores major algorithm updates from 2020 to 2025, key ranking factors, and what they mean for your strategy moving forward.

Understanding the Instagram Algorithm’s Evolution

Since 2020, Instagram has shifted its focus to enhancing user experiences, prioritizing video content, and increasing discoverability through recommendations. Each year brought innovations that shaped how content is ranked, viewed, and interacted with.

Here’s a year-by-year breakdown of the major updates Instagram introduced, rethinking how creators and brands engage with audiences.

2020 The Rise of Reels and Content Recommendations

The introduction of Reels in 2020 marked Instagram’s challenge to TikTok’s growing dominance. This short-form video format boosted discoverability for creators, brands, and influencers. Additionally, Instagram launched Suggested Posts, extending the reach of viral content by recommending posts from accounts users didn’t already follow.

What brands learned in 2020:

• Viral Reels grew accounts quicker than photos ever could.
• Suggested posts enhanced opportunities for non-followers to discover new content.

Example: Fashion brands like Gucci utilized Reels to showcase limited collections, resulting in significantly higher visibility and engagement.

2021 Prioritizing Video and Creator Features

By 2021, Instagram declared "we are no longer a photo-sharing app," focusing heavily on videos and creator empowerment. Features like IGTV merging into Instagram Video and expanded Shopping tools underlined e-commerce integration. AI-driven recommendations also gained prominence, delivering personalized feeds that balanced followed accounts and algorithm-selected posts.

Key Takeaways from 2021:

• Short-form video formats received higher ranking in feeds.
• Tools like Instagram Shops encouraged hybrid content combining commerce and creativity.

Example: Influencers like Charlie D’Amelio seamlessly promoted brands through shoppable videos, blurring the line between creator-led storytelling and e-commerce.

2022 Chronological Feeds Return But AI-Proposed Content Dominates

Following user feedback, Instagram reintroduced chronological feed options via the “Following” and “Favorites” tabs in early 2022. Despite this impressive update, users found themselves interacting more with AI-recommended posts, generated for relevance to personal preferences.

Evolutionary Highlights from 2022:

• The merging of IGTV with Reels solidified video as Instagram’s central focus.
• TikTok-style full-screen feeds sparked conversation but were rolled back following criticism.

Example: Brands like Nike used Reels paired with chronological tools to strategize campaigns that reached both followers and broader audiences seeking fresh content.

2023 AI Recommendations Advance Content Discovery

By 2023, an astounding 20-30% of feed content comprised posts from accounts users didn’t follow. AI advancements enabled Instagram to predict user preferences with pinpoint accuracy. Collab posts and Remix for Reels also empowered creators to co-author content, deepen engagement, and drive virality.

Lessons Learned:

• Reels became the dominant content discovery format.
• Collaborations encouraged seamless partnerships between creators and brands.

Case Study: A local bakery leveraged AI recommendations by utilizing trending audio in their Reels. Their content reached non-followers, resulting in a 40% uptick in foot traffic to their store.

2024 Transparency and Views as the New Metric

Transparency became a key focus, with Instagram introducing ‘Recommendations Reset’ tools allowing users to wipe content preferences. Additionally, ‘views’ overtook likes as the main success metric, placing emphasis on reach rather than interaction. Alongside this, hashtags lost their clout as Instagram leaned into SEO-driven discovery via keywords.

Game-Changing Takeaways from 2024:

• Rank optimization shifted toward generating content that resonated widely, encouraging more views over likes.
• Brands had to pivot strategies to align with search-driven discovery rather than hashtag campaigns.

Example: Leading cosmetic brands like Fenty Beauty harnessed Instagram’s new keyword-centric SEO to embed products into influencer posts, driving increased search-based clicks.

What’s New in 2025 Short-Form Video and User Control

The 2025 Instagram Algorithm has aligned with user behavior demanding short-form video content over static posts. Reels not only dominate Explore but also appear at the top of user feeds. Additionally, the platform now provides users with greater control of their feed via global reset buttons to refresh the content experience.

The New Norm in 2025:

• Videos from brands need ultra-high completion rates to maintain algorithmic favor.
• Transparency tools empower users, signaling a deeper trust-building opportunity for businesses.

Stat Insight: According to Instagram, 81% of users prefer short-form videos from brands, making Reels a must-have for marketers in 2025.

Example: Footwear brand Allbirds runs campaigns using seamlessly-looping Reels to increase watch time. These short, captivating videos also leveraged trending sounds to boost engagement from new audiences.
