How the LinkedIn Algorithm Works
LinkedIn’s feed is built to surface professionally relevant content and keep people engaged on the platform. A useful way to picture it: every post passes a quick quality check, then gets a short early test with a slice of your network, and — if it performs — gets shown more widely to people likely to care, increasingly based on topic and interest rather than only who you know.
The three rough phases
- Filtering. LinkedIn screens for spam and low-quality content before distribution.
- The early test. The post is shown to a portion of your network. Engagement in the first hour or two — especially comments and dwell time — tells LinkedIn whether to push it further.
- Wider distribution. Posts that pass get shown beyond your immediate network to people LinkedIn predicts will find them relevant, increasingly by topic and interest.
The signals that matter
- Comments and replies. Stronger than likes, particularly when people respond to each other.
- Dwell time. How long people stop to read. Long-form text and document carousels earn dwell time, which is part of why they perform.
- Early engagement from relevant people. Engagement from people connected to your topic counts for more than volume from anyone.
- Format. Native content tends to out-reach posts that push people off-platform.
What it means for how you post
LinkedIn rewards content that earns real conversation, so the move is to say something worth responding to — a clear opinion, a specific lesson, a useful framework — not a generic business cliché. The platform openly punishes empty corporate language by being ignored. This is where a distinctive voice wins: it is what makes people stop, read, and reply.
The honest version
LinkedIn keeps changing the underlying models, and the exact mechanics are not published. But the durable principle holds: it tests posts on early engagement, rewards comments and dwell time over quick likes, favours native content, and increasingly distributes by interest. Write things people actually want to discuss, and the mechanics work in your favour.
Frequently asked questions
Do comments matter more than likes on LinkedIn?
Generally yes. Comments — especially thoughtful ones and replies between people — signal more engagement than a like, and they keep a post active longer. Dwell time (how long people stop to read) also matters more than a quick reaction.
Does LinkedIn suppress posts with external links?
LinkedIn favours content that keeps people on the platform, so posts that send people off-site can see less reach than native posts. A common workaround is to put the link in the first comment, though the practical effect varies and changes over time.
How long does the LinkedIn algorithm take to decide a post’s reach?
Early engagement matters a lot. Roughly the first hour or two acts as a test — if the post earns engagement from relevant people quickly, LinkedIn expands its reach; if not, distribution slows.
