Post Anatomy
┌─────────────────────────────────────┐
│ HOOK (first 1-2 lines) │ ← Visible before "...see more"
│ │
│ ...see more ─────────────────────── │ ← The click gate
│ │
│ BODY (story/value) │
│ - Formatted with line breaks │
│ - Short paragraphs (1-2 sentences) │
│ - Lists or numbered points │
│ │
│ CTA (last 1-2 lines) │ ← Ask for engagement
│ │
│ #hashtags (3-5) │
└─────────────────────────────────────┘
Character Limits
Element
Limit
Post text
3,000 characters
Visible before "see more"
~210 characters (~2 lines on mobile)
Hashtags
3-5 recommended
Comment
1,250 characters
Article title
100 characters
Article body
125,000 characters
The first 210 characters are everything. If the hook fails, nobody clicks "see more."
Hook Formulas
What Works
Formula
Example
Contrarian opinion
"Unpopular opinion: code reviews are a waste of time."
Personal story opening
"I got fired on a Tuesday. Best thing that ever happened."
Surprising stat
"92% of startups fail. But not for the reason you think."
List promise
"I've hired 200+ engineers. Here are 5 red flags I look for."
Bold statement
"Your resume doesn't matter. Here's what does."
Before/after
"3 years ago I couldn't get a single interview. Yesterday I turned down a FAANG offer."
Pattern interrupt
"Stop. Before you send that cold email, read this."
What Fails
❌ "Excited to announce that we are pleased to share..." (corporate speak)
❌ "In today's rapidly evolving landscape..." (cliché, says nothing)
❌ "I'd like to take a moment to..." (slow, no hook)
❌ "Just published a new blog post!" (no value proposition)
❌ Starting with a hashtag or emoji
Formatting Rules
Line Breaks Are Your Best Friend
❌ Dense paragraph:
"I learned something important about leadership last week. My team was struggling with a deadline and instead of pushing harder, I decided to remove scope. The result was incredible — we shipped faster and the quality was better. Sometimes less really is more."
✅ Formatted for LinkedIn:
"I learned something about leadership last week.
My team was struggling with a deadline.
Instead of pushing harder, I removed scope.
The result?
We shipped faster.
And the quality was BETTER.
Sometimes less really is more."
Formatting Guidelines
Rule
Why
One sentence per line
Easier to scan on mobile
Blank line between paragraphs
Visual breathing room
Short paragraphs (1-2 sentences)
Mobile readability
Use line breaks for dramatic effect
Creates pacing and suspense
Bold key phrases sparingly
Draws eye to important points
Numbered lists for tips
Scannable, shareable
Avoid walls of text
Nobody reads them

Link Posts Strategy
LinkedIn penalizes posts with links (reduces reach). Workarounds:
Comment method: Post without link, add link as first comment, edit post to say "Link in comments"
No-link method: Summarize the content in the post itself, mention "DM for link"
If you must link: Put it at the very end, after strong standalone content
Content Pillars
Every LinkedIn creator should have 3-5 pillars they rotate through:
Pillar
What It Covers
Example
Expertise
Industry knowledge, how-tos
"5 database patterns every engineer should know"
Stories
Personal experiences, failures, wins
"The hardest feedback I ever received"
Opinions
Takes on industry trends, contrarian views
"AI won't replace engineers. Bad managers will."
Behind the scenes
Building in public, process
"Here's our actual sprint retrospective format"
Curated insights
Trends, data, research summaries
"I analyzed 500 job postings. Here's what changed."
Algorithm Signals
Signal
Impact
How
Dwell time
Very High
Longer posts that people read fully
Comments
Very High
Ask questions, create discussion
Saves
High
Actionable, reference-worthy content
"See more" clicks
High
Strong hook that makes people expand
Shares
Medium
Relatable, quotable content
Reactions
Medium
Easy to get but weighted less
External links
Negative
Reduces reach — put links in comments
Editing after posting
Negative
Don't edit within first hour
Posting frequency
3-5x/week
Daily is fine, more than 1/day hurts
Posting Schedule
Day
Best Time (your audience's timezone)
Tuesday-Thursday
7-8 AM, 12 PM, 5-6 PM
Monday
8 AM (people catching up)
Friday
7-8 AM (before checkout)
Weekend
Skip or light content
Engage in comments for 30-60 minutes after posting — this is more important than the post itself.
