How Does the Facebook Algorithm Work in 2026?
The Facebook algorithm is the ranking system that determines which posts appear in each user's News Feed and in what order. It evaluates thousands of signals for every piece of content - including who posted it, what type of content it is, how much engagement it receives, and the viewer's past behavior - to predict which posts each user will find most valuable. According to Meta's own documentation, the algorithm processes millions of ranking factors for each user's feed, making it one of the most complex content recommendation systems in existence.
For businesses and startups, understanding how this algorithm works is essential because it directly controls how many people see your organic content - and that number has been declining steadily for over a decade.
How Does Facebook Rank Content?
Facebook's ranking system operates in four stages for every piece of content:
Inventory
The algorithm collects all available content that could appear in a user's feed - posts from friends, followed Pages, joined Groups, and recommended content from accounts the user does not follow.
Signals
The algorithm evaluates hundreds of signals about each post:
- Relationship signals: How often the user interacts with the poster. Frequent commenters and message contacts are weighted heavily.
- Content type signals: Whether the post is video, photo, link, or text. The algorithm learns each user's format preferences over time.
- Engagement signals: How many reactions, comments, and shares the post has received, especially from people the user is connected to.
- Recency: Newer posts are weighted higher, though high-engagement older posts can resurface.
Predictions
The algorithm predicts the probability that the user will interact with each post - specifically, whether they will like it, comment on it, share it, or spend time reading or watching it.
Relevance Score
Each post receives a score based on these predictions. Posts are ranked by score, and the highest-scoring content appears at the top of the feed.
What Does the Facebook Algorithm Prioritize in 2026?
Facebook has made clear through multiple algorithm updates that it prioritizes "meaningful social interactions" over passive consumption.
Conversations Over Clicks
Posts that generate back-and-forth comments between users receive the strongest distribution boost. A post with 20 comments where people are discussing the topic will outperform a post with 200 likes but no comments. This is why asking genuine questions and sparking debates outperforms broadcast-style posting.
Groups Over Pages
Facebook Groups content typically reaches a higher percentage of members than Page content reaches followers. The algorithm treats Groups as community spaces where engagement is naturally higher, giving Group posts distribution advantages. This is why Facebook Groups marketing has become a core strategy for brands still investing in the platform.
Reels and Video
Facebook has been pushing short-form video (Reels) aggressively since 2022, giving Reels content additional distribution compared to static posts. Meta reported that Reels plays across Facebook and Instagram exceeded 200 billion per day in 2024. For startups creating video content, Facebook Reels is an underutilized distribution channel.
Original Content Over Reshares
The algorithm deprioritizes content that is reshared from other platforms (especially content with TikTok or Instagram watermarks) and prioritizes original content created natively for Facebook.
How Does Facebook Organic Reach Compare to Other Platforms?
Facebook's organic reach for business Pages has declined dramatically over the past decade. Research from Socialinsider shows the average Facebook Page reaches approximately 2 to 5 percent of its followers with each post. Compare this to:
- TikTok: 25 to 30 percent organic reach for small accounts
- LinkedIn: 5 to 10 percent organic reach
- Instagram: 3 to 5 percent organic reach
- Twitter: Highly variable, impression-based
This low organic reach is why many startups question whether Facebook is still worth the investment. The answer depends on your strategy - if you are only posting to a business Page, the reach numbers are discouraging. If you are leveraging Groups, Reels, and community-driven content, Facebook still provides meaningful distribution.
How Do You Optimize Content for the Facebook Algorithm?
Post Content That Sparks Conversation
Ask questions. Share opinions that people will agree or disagree with. Post content that makes people want to tag a friend. The algorithm rewards conversation, so design your content to start one.
Use Video, Especially Reels
Short-form video content receives distribution boosts on Facebook. If you are already creating content for TikTok or Instagram Reels, adapting it for Facebook Reels is a low-effort way to extend reach.
Engage in Groups
Build or participate in relevant Groups. Content posted in Groups reaches a higher percentage of members and generates more engagement than equivalent content on Pages. At Conbersa, we have seen startups achieve 5 to 10 times the reach from Group content compared to Page posts.
Post Consistently but Not Excessively
One to two posts per day on your Page is the sweet spot. Posting more frequently can actually reduce per-post reach as the algorithm throttles content from accounts it perceives as spammy. Focus on quality and conversation potential over volume.
Respond to Comments Quickly
When someone comments on your post, reply within the first hour if possible. Your reply triggers a notification that brings the commenter back, often generating a follow-up comment. This creates the back-and-forth conversation pattern the algorithm rewards most heavily.
The Facebook algorithm is complex, but the core principle is simple: create content that makes people want to talk to each other. Everything else is optimization on top of that foundation.
