How the LinkedIn Algorithm Actually Works in 2025
The LinkedIn algorithm is not as opaque as it seems. Understanding a few key factors can dramatically increase your reach.
The Three Phases of Post Distribution
Every LinkedIn post goes through three phases:
Phase 1: Initial Quality Check LinkedIn's AI scans your post for spam signals, engagement bait, and quality indicators. Low-quality posts get limited reach from the start.
Phase 2: Test Audience Your post is shown to a small subset of your network (roughly 10-15% initially). If it performs well with this group, it expands.
Phase 3: Extended Reach High-performing posts break out of your network and reach second and third-degree connections.
What Triggers the Algorithm
Dwell Time: How long people spend reading your post. This is why longer posts with good hooks can outperform short ones.
Comments: Weighted heavily, especially meaningful comments rather than "great post!" type responses.
Saves and Reposts: Strong signals that content is valuable enough to revisit or share.
Profile Clicks: When people click to your profile after seeing your post, LinkedIn interprets this as high interest.
The First Hour Matters
Like most social algorithms, LinkedIn frontloads early engagement. Posts that get quick interaction in the first 30-60 minutes get more distribution.
This is why posting when your audience is online matters more than posting at theoretically "optimal" times.
What Hurts Your Reach
External Links: LinkedIn deprioritizes posts with links because they take people off-platform. Put links in comments instead.
Editing After Posting: Significant edits can reset your post's momentum.
Engagement Bait: "Like if you agree" type content gets penalized.
Posting Too Often: Multiple posts per day compete with each other and can hurt overall reach.
Content Type Performance
Text-only posts currently get the widest reach. Carousels perform well for saves and engagement. Videos get decent reach but lower engagement.
LinkedIn prioritizes whatever format is underused. Right now that means text posts outperform video because everyone flooded into video.
