The LinkedIn Prompt I Use So Posts Take Minutes, Not Half an Hour

I used to sit on LinkedIn for 20 or 30 minutes staring at a blank box. Then I would type "write a post about AI" into ChatGPT, paste something safe, and get almost no comments.

That was on me. The model was doing exactly what I asked. I asked for nothing useful.

The weak prompt (stop using this)

Write a LinkedIn post about AI.

Problems:

1. No who you are
2. No concrete result
3. No audience
4. No ask at the end

You get a polished paragraph that sounds like every other polished paragraph.

The prompt I use now

Act as a freelance [your role].
Write a LinkedIn post under 120 words.
Audience: [who you want to hire you].
Highlight one specific result from this week: [metric or win].
Tone: friendly and direct, like a message to a peer.
End with one question they can answer in a comment.
Do not use hype words or em dashes.

Fill the brackets. Run it. Edit two lines by hand. Post.

Why this works

Recruiters and clients skim. They look for proof. "I cut page load by 50% with Next.js image settings" beats "I love building with modern tools."

A question at the end is free engagement. People answer. The algorithm notices.

Real example from my week

Weak version:

Excited to share that I finished another project. Grateful for the opportunity. Looking forward to what is next.

Stronger version from the template:

Wrapped a client Next.js deploy where we fixed broken blog images by allowing the image host in CSP. Small config change, big trust fix on the portfolio. If your cover images show alt text instead of photos, what host are you loading from?

Same person. Different prompt.

Keep a note of wins

I keep a short list on my phone:

• Metric from the week
• Who I want to reach
• One question

When it is time to post, I do not invent a story. I plug the list into the template.

OpenAI's own prompting guide says the same thing in fancier words: be specific about role, task, and format.

What not to do

• Do not post raw AI text without a human pass
• Do not claim income you did not earn
• Do not write "ultimate guide" titles for a 3-sentence tip

Your name is on the post. Edit it like your reputation matters, because it does.
