How the LinkedIn Algorithm Works in 2025

The LinkedIn algorithm determines which posts appear in each user's feed and in what order. Understanding how it works is crucial for maximizing your content's reach and engagement.

The 4-Phase Distribution Model

Phase 1: Spam Filter (0-5 minutes)

Every post is immediately checked by automated classifiers for spammy language, excessive links, and low-quality signals.

Phase 2: Credibility Test (1-2 hours)

Your post is shown to 1-5% of your connections. The algorithm monitors engagement velocity.

Phase 3: Broader Network (2-24 hours)

Posts that pass the credibility test appear in 2nd and 3rd-degree connection feeds.

Phase 4: Extended Distribution (24+ hours)

Top-performing posts enter broader distribution through notifications and email digests.

Engagement Signals That Matter

Comments are weighted 10x more than likes. Dwell time (how long someone reads your post) is a strong signal. Shares extend reach to new networks. Saves indicate high-value content.

What the Algorithm Rewards

• Original, text-heavy posts with personal insights
• Posts that spark meaningful conversations
• Consistent posting schedule (3-5 times per week)
• Content that keeps users on the platform

What the Algorithm Penalizes

• External links in the post body
• Engagement bait ("Like if you agree")
• Excessive hashtags (more than 5)
• Posting more than once per day
