Formatting Rules
- Character limit: 3000 chars. Optimal: 1200–1800 chars.
- No markdown: LinkedIn renders asterisks and hashes as plain text. Use line breaks instead.
- Paragraphs: 1–3 sentences max per paragraph. Single blank line between paragraphs.
- Hooks: First 2 lines visible before "...see more" — make them count.
- Lists: Use dashes or numbers preceded by a line break, not bullet markdown.
- Emojis: Maximum 2 if used. None preferred for research/technical audience.
Post Structure Conventions
[HOOK — 1-2 lines, no context-setting]
[Short setup paragraph — 2-3 sentences]
[Core argument or insight]
[Supporting point 1 — specific, concrete]
[Supporting point 2 — specific, concrete]
[Supporting point 3 — specific, concrete]
[Landing — declarative, no question, no CTA]
Algorithm Notes (2026)
- Post in the first 2 hours of target audience's active time (US: 7–9am or 12–1pm ET)
- First 60 minutes determine distribution; engage with substantive early comments
- Save rate is primary distribution signal — optimize for saves, not likes
- Native content outperforms link-in-post
- Editing within first hour resets distribution window
What NOT to Do
- No "hashtag spam" (2 max if used at all)
- No "What do you think?" ending
- No "I'm excited to share..."
- No tagging people who aren't directly referenced
- No reposting your own post in comments
