LinkedIn glossary
Plain-language definitions for the LinkedIn content terms that come up in posts about hooks, reach, voice, and the algorithm.
Writing & format
Terms for the craft of LinkedIn posts: hooks, formats, structure, voice.
Hook
The first line of a LinkedIn post. It is shown above the See more fold and decides whether anyone keeps reading.
Scroll stopper
Any element of a LinkedIn post that breaks a reader out of passive scrolling and earns active attention.
Preview text
The portion of a LinkedIn post visible in the feed before the See more truncation. Roughly the first 200 characters.
Hook-story-lesson
A three-part LinkedIn post structure: a hook to earn attention, a short story for context, and a lesson the reader can take away.
Listicle
A LinkedIn post built as a numbered or bulleted list. Easy to scan, easy to overuse.
Observation post
A short LinkedIn post that states a single specific observation, often without a story or call to action.
Rule of three
A three-item parallel construction used for rhythm. Effective in speeches; on LinkedIn it now reads as AI-generated.
Engagement & reach
How LinkedIn measures and surfaces content: impressions, dwell time, signals.
Dwell time
How long a LinkedIn user pauses on a post in their feed. A core ranking signal for distribution.
Impressions
One display of a post in a LinkedIn user's feed. The starting metric for every engagement funnel.
Engagement rate
Engagements (reactions, comments, shares) divided by impressions, expressed as a percentage. A post-quality metric.
Reach
The number of unique LinkedIn users who saw a post at least once. Reach less than impressions implies repeat views.
Social proof
Visible evidence on a post that other people found it worthwhile: reactions, comments, shares, and who specifically engaged.
Comment quality
How substantive the comments on a post are. Length, specificity, and relevance all matter to LinkedIn's distribution model.
Engagement bait
Posts that explicitly ask for likes, comments, or shares without earning them. Increasingly downweighted by LinkedIn.
Strategy & cadence
Higher-level concepts: content pillars, voice DNA, posting rhythm, personal brand.
Content pillars
The 3-5 recurring themes a LinkedIn account writes about regularly. Pillars give followers a reason to stay subscribed.
Content cadence
The rhythm of how often an account posts on LinkedIn. Consistent cadence beats high frequency.
Voice DNA
The specific combination of vocabulary, sentence rhythm, and tone that makes a person's writing recognizable as theirs.
Thought leadership
When a LinkedIn account becomes known for a specific perspective on a specific topic. Earned through consistency, not self-declared.
Personal brand
What other people associate with your name when you are not in the room. On LinkedIn, this is shaped by profile, posts, and voice consistency.
Evergreen content
LinkedIn posts that stay relevant long after publication. Topics with durable demand, not news-cycle content.
Platform mechanics
How LinkedIn itself works: algorithm signals, character limits, post types.
LinkedIn algorithm
The ranking system LinkedIn uses to decide which posts appear in which users' feeds.
Character limit
LinkedIn allows up to 3,000 characters in a text post. Strong posts typically use 800-1,500. The first 200 are critical.
Carousel post
A LinkedIn post made of multiple slides (uploaded as a PDF) that readers swipe through.
Tagging
@-mentioning a person or company in a LinkedIn post. Notifies the tagged account; can earn or sour the relationship.
