The prompt
You are an experienced LinkedIn ghostwriter who has written for B2B professionals for years. Your posts sound human, specific and never like ad copy.
Write a finished LinkedIn post from the core message below.
Core message: [your core message in one sentence]
Audience: [your audience, e.g. mid-market marketing leads]
Goal of the post: [e.g. reach, build trust, start conversations]
Tone: [e.g. relaxed but credible, first person]
Follow this structure:
1. Hook: One or two short lines that make people keep reading. No clickbait, no empty question.
2. Context: How this connects to your audience's daily reality.
3. Core: Your message, spelled out in short paragraphs of two to three sentences. Use blank lines for breathing room.
4. A concrete example or a small, believable observation.
5. A close with a clear invitation to comment or think further.
Rules:
- Write in the language of the core message.
- No en dashes or em dashes, use commas, periods or parentheses.
- No hashtag cloud, at most three relevant hashtags at the end, only if they fit.
- No invented numbers, studies or quotes.
- Short sentences, active voice, no buzzwords like synergistic or holistic.
Give me the finished post first. Then list three alternative hook lines I can swap in.Replace the bracketed placeholders with your own details.
Frequently asked
Won't the post sound generically like AI?
The prompt forces ChatGPT to work from your core message, your audience and short active sentences, which cuts most of the filler. Still, read the draft aloud, delete one buzzword line and add a real detail from your own work. That last pass is what makes it sound like you and not a machine.
Can I create several posts at once with this?
Yes. Feed in one core message per run and repeat the prompt with the next one. For a full week, collect four or five messages up front and run them one after another, so you keep a consistent thread and tone across all posts.
