How LinkedIn decides
who sees your post.

LinkedIn shows your post to a small group of people, watches what they do, and decides whether to show it to more. Most of what is written online about how this works is guesswork presented as fact. Below, every claim is tagged by how well supported it is, so you can tell the difference between a rule and a rumour.

Confirmed by LinkedIn

Stated by LinkedIn engineering, its Help Centre, published LinkedIn research or a named executive on the record.

Credible research

Large independent studies with disclosed method. Directionally reliable, not auditable against LinkedIn's own logs.

Folklore

Repeated everywhere, sourced nowhere. Some of it is probably true. None of it should drive a decision on its own.

The evidence table

What we know, ranked by how well we know it.

Tap a row to open the detail, the source and what it means for a draft.

LinkedIn's Feed AI team published how it measures the time a member spends on a post in-feed, even with no like or comment, and uses it as an implicit quality signal. It was built specifically to separate genuinely engaging content from clickbait that gets a fast skip.

So what, for your draft

Reading time matters more than reactions. A post that holds someone for eleven seconds beats a post that collects three polite likes in one. This is the strongest argument for short paragraphs and a genuinely interesting middle.
Signal weighting

Not all engagement is worth the same.

An indicative ranking, built from LinkedIn's own statements where they exist and the best independent research where they do not. The exact numbers are ours, not LinkedIn's. The order is the point.

Dwell time

Confirmed. Time on the post in-feed.

96

Substantive comments

Long replies outrank one-word ones.

88

Topic relevance to the reader

The interest graph, not just who you know.

84

Sends and saves

Private shares show strong interest.

78

Reshares with commentary

Reshares with no added text count for much less.

66

Author expertise on the topic

Posting regularly on one subject builds reach over time.

60

Reactions

Easy to give, so they carry little weight.

30

Hashtags

Confirmed as no longer helping discovery.

8

Format

Choosing a format.

Text only

Stories, opinions, observations, anything where the words are the value.

The most reliable format. Quickest to produce and tends to get the best comments.

Text plus one image

A photo that is genuinely from the moment described. A screenshot as evidence.

Stock imagery adds nothing and can cost you. If the image is decoration, cut it.

Document carousel

Frameworks, checklists, teardowns, before-and-after work.

Consistently top of format studies. Six to ten slides, one idea per slide, portrait or square.

Native video

Anything where tone of voice or a demonstration does the work.

Strong in every recent study. Subtitle everything. First three seconds matter as much as a hook line.

Newsletter

Recurring, substantial pieces with a subscriber base worth building.

Publishing notifies every subscriber directly, which is the only guaranteed distribution on the platform.

Poll

Rarely. Only when you genuinely want the answer.

Performance has fallen sharply since 2024 across every tracker.
