What is linkedin algorithm?

The LinkedIn algorithm works in three phases: an initial test with a small audience during the first 90 minutes, an evaluation phase based on qualified engagement (comments, saves, shares) between 90 minutes and 8 hours, and a viral amplification phase if the signals are positive over the following 72 hours.

The signals that carry the most weight in 2026 are dwell time (how long users spend reading the post), the comments-to-likes ratio, the proportion of long comments versus simple reactions, and the percentage of audience that interacts during the first hour. The algorithm penalizes content detected as 100% AI-generated without human editing, outbound links inside the body of the post, and the literal reuse of other users' content.
