Glossary: Master the LinkedIn Algorithm

Every key term from the course, in plain English. When a lesson says a word you don't know, it lives here.

The Dwell Test

Before publishing, read your post as a stranger and ask: would I stop scrolling for ten full seconds — and would I click 'see more'? If either answer is no, rewrite the opening until both are yes.

The Comment Ladder

The four-rung climb from invisible liker to commenter to conversation-starter to recognized voice. The critical threshold is rung two — around four genuine sentences — where comments cross into 'meaningful' territory.

Dark Reach

The invisible spread your content generates: profile views, screenshots shared in private channels, silent readers who DM months later. Never appears in analytics; where B2B business actually happens.

Dwell time

How many seconds a viewer keeps your post on screen. The algorithm's strongest ranking signal, because sustained attention is the hardest signal to fake.

Golden hour

The first 60–90 minutes after posting, when the algorithm measures early reactions from a test audience to decide how widely to distribute your post.

Golden-hour test

The distribution mechanism itself: every new post is shown to a small test audience first, and strong early signals unlock wider tiers of reach.

Meaningful engagement

The engagement tier the algorithm actually weighs: comments of four or more words, reply threads, saves, and shares with added commentary. Depth beats volume.

Content pillar

One of your 3–4 recurring posting themes, each doing a different job (teach, prove, opine, connect). Pillars kill blank-page panic and build topical credibility.

Credibility signal

The algorithm's slow-moving judgment of your account: topical consistency, engagement quality, and authenticity over time. Specialists compound it; generalists never build it.

Employee advocacy

Team members posting genuinely from personal profiles — which systematically out-distribute the same content from company pages, because people trust people.

'See more' click

When a reader expands your post past the two-line cut. The most valuable single micro-action: it logs deliberate intent to keep reading and starts the dwell clock.

Reply thread

A comment conversation with multiple back-and-forth replies — especially with the author participating. Each reply adds dwell time and engagement the algorithm weighs heavily.

Engagement bait

'Comment YES if you agree' and its cousins: begging for interaction without earning it. Detected and downranked — the algorithm rewards earned attention only.

Engagement pod

A group that agrees to like and comment on each other's posts. The pattern is obvious in the data, and the penalty is a quiet, lasting reach reduction. Never join one.

Test audience

The small initial group — some connections, some strangers — shown your post first. Their reactions in the golden hour decide whether distribution widens or stalls.
