Most coaches know they should post on LinkedIn. The problem isn’t motivation, it’s the blank box. You sit down to share something valuable and twenty minutes later you’ve written, deleted, and rewritten the same first line four times.

This LinkedIn post prompt for coaches removes that friction. You give the AI one idea, your niche, and the action you want readers to take, and it returns a post built the way high-performing LinkedIn content is actually built: strong hook, white space, one clear takeaway, soft call to action. And by the end of this page you’ll understand why it works, so your next prompt is even sharper.

When to use this

• You have a lesson, client win, or opinion in your head but no time to shape it.
• You want to stay consistent on LinkedIn without hiring a ghostwriter.
• You’re repurposing a podcast moment, a coaching insight, or a newsletter into a native post.
• You want a few hook variations to A/B test.

The prompt

Copy this whole block into ChatGPT, Claude, or Gemini:

You are an expert LinkedIn ghostwriter for coaches. Your job is to turn one idea into a single high-performing LinkedIn post that builds authority and trust.

Before writing, ask me up to 3 clarifying questions if anything below is unclear. Otherwise, proceed.

CONTEXT
- My niche: {{NICHE}}
- My ideal reader: {{IDEAL_READER}}
- The core idea, lesson or story I want to share: {{IDEA}}
- The action I want readers to take: {{CTA}}
- My tone: {{TONE}}

TASK
Write ONE LinkedIn post that:
1. Opens with a scroll-stopping hook (max 2 short lines, no hashtags in the hook).
2. Uses short, punchy paragraphs of 1-2 sentences with plenty of white space.
3. Delivers one clear, valuable takeaway my ideal reader can act on today.
4. Sounds human and matches my tone. No corporate buzzwords, no 'in today's fast-paced world'.
5. Ends with a soft, natural call to action: {{CTA}}.
6. Lists 3-5 relevant hashtags on a separate line at the very end.

CONSTRAINTS
- 120-200 words.
- No emojis unless my tone is casual.
- Do not invent statistics or fake client results.

After the post, give me 2 alternative hooks I could A/B test.

How to customize it

Replace the five {{VARIABLES}} before you send it:

Here is the exact prompt, filled in for a leadership coach. This is the whole input, nothing hidden:

You are an expert LinkedIn ghostwriter for coaches. Your job is to turn one idea into a single high-performing LinkedIn post that builds authority and trust.

Before writing, ask me up to 3 clarifying questions if anything below is unclear. Otherwise, proceed.

CONTEXT
- My niche: leadership coaching for first-time managers
- My ideal reader: newly promoted managers who secretly feel like impostors
- The core idea, lesson or story I want to share: the fastest way to earn your team's trust is to admit what you don't know
- The action I want readers to take: comment 'LEAD' and I'll send my free 30-day first-time-manager checklist
- My tone: warm, direct, lightly funny

TASK
Write ONE LinkedIn post... [rest of the prompt unchanged]

And here is the complete output the model returns:

You got the promotion because you were great at the work.

Then nobody handed you the manual for the part that actually matters now: the people.

Here’s the trap almost every new manager walks into. You think you’re supposed to have every answer, so you bluff. You nod in meetings. You pretend the strategy makes sense when it doesn’t.

Your team can smell it in about a week.

The managers I coach who earn trust fastest do the opposite. Early on, they say a version of this: “I don’t have all the answers yet. What I can promise is that I’ll listen, I’ll be straight with you, and I’ll go to bat for this team.”

That’s it. No grand vision speech. No pretending.

Admitting what you don’t know isn’t weakness. It’s the most disarming thing a new leader can do, because it gives everyone else permission to be human too.

You were promoted for your competence. You’ll be followed for your honesty.

Comment “LEAD” and I’ll send you my free 30-day first-time-manager checklist.

2 alternative hooks to A/B test: 1. “Your team figured out you were bluffing in week one. Here’s what to do instead.” 2. “The best thing I ever told a brand-new team: ‘I don’t have all the answers yet.'”

That is publish-ready. A 15-second human tweak to the first line and it’s live.

Why this works

Three LLM principles are doing the heavy lifting here. Learn them and every prompt you write gets better:

1. Role priming. The first line (“You are an expert LinkedIn ghostwriter for coaches”) tells the model which slice of its knowledge to draw from. “Write me a post” pulls from the bland average of the internet; “act as an expert ghostwriter” pulls from the good stuff. Always assign a role.
2. Specificity in, specificity out. The model can only be as specific as your input. A vague idea (“leadership is important”) yields a vague post. A sharp, concrete idea (“trust is earned by admitting what you don’t know”) yields a sharp post. The quality of the output is capped by the quality of your {{IDEA}}.
3. Constraints are quality control. The numbered rules and the “no buzzwords / no fake stats” lines aren’t decoration. Each one removes a common failure mode. Telling the model what NOT to do is as powerful as telling it what to do. And the “ask me up to 3 clarifying questions first” line lets it fill gaps by asking instead of guessing, which is the single biggest fix for generic AI writing.

Do this now

1. Copy the prompt above into ChatGPT or Claude.
2. Replace the five variables with your real niche, reader, idea, CTA, and tone.
3. Send it. If it asks clarifying questions, answer them honestly.
4. Tweak the first line in your own words, then post it today. Done beats perfect.

Pro tips

• Feed it a real moment. A specific client story or a real (sharable) number beats any abstract lesson. Specificity is the whole game.
• Keep the clarifying-questions line. It is the difference between a post that sounds like you and one that sounds like everyone.
• Run it twice with two tones. Generate one warm version and one punchy version, then keep the better hook.
• Build a hook swipe file. Save every alternative hook it gives you; within a month you’ll have a library of openers that work for your audience.
