Transform Your LinkedIn Strategy with Custom GPT: A Step-by-Step Guide

Introduction: From Idea to Impact in 20 Minutes

Imagine writing high-converting LinkedIn posts in under 20 minutes—without staring at a blank screen. That’s exactly what I wanted when I built my own custom GPT: Voice of Impact.

It wasn’t just about saving time. It was about building real traction with the clinicians I coach—doctors who want to make medicine their side hustle, launch meaningful ventures, and be known for something beyond patient care.

In this article, I’ll walk you through how I use my GPT daily to generate content that sounds like me, resonates with my ideal clients, and helps build momentum around my programs like the Clinician Impact Actionship.

Start With Clarity: Who Are You Really Speaking To?

The first time you use GPT for content, you realize: AI is only as useful as the clarity you bring to the table. So The Voice of Impact GPT doesn’t ask, “What do you want to write today?” It asks:

Who are you trying to help?

What are they struggling with?

Where are they stuck on the journey?

That’s because my version was trained on my own Ideal Client Avatar: mid- to senior-level UK clinicians (age 38–55) who want to launch expert-led ventures—but feel stuck between too many ideas, and too much to lose.

These are the bridge-builders I talk about in my programs: respected, restless doctors who don’t want to quit medicine, but want more control, credibility, and traction. The GPT helps me write directly to them—because it remembers them.

The Daily Workflow: 3 Simple Steps

Here’s how I use my custom GPT every weekday in under 20 minutes:

1. Contextual Kickstart

Each day, I feed it a tiny prompt: "Today I want to talk about the fear of being seen as 'too commercial'." Or "Help me with another post for today, please" (I always say please and thank you to my GPT)

The GPT then reflects back a draft in my tone—thoughtful, direct, story-led. It follows my format: story > insight > pivot > CTA. Often it will ask a refining question before giving me content.

2. Co-Creation, Not Delegation

Instead of telling GPT what to write, I co-create with it. It asks me questions that help me:

Reframe ideas based on coaching conversations

Pull in language from real clients

Structure messy thoughts into value-driven stories

3. Polish + Publish

Once I get a draft, I (may) spend 5–10 minutes rewriting key lines, adding nuance, or dropping in a personal anecdote. Then I post.

Done. Simple. Repeatable. Insight-led.

Write with AI

Real-World Wins: From Insight to Inbound

This system is what helped me:

• Grow my LinkedIn to 5,000+ followers and over 7,000 weekly impressions

• Turn posts into podcast scripts, webinar segments, and email content

• Attract the right clients—like the fetal medicine doctor who wanted to scale her influence in AI and education

She found me through a post I wrote (in 18 minutes) about the "quiet power of clinical credibility." That post? Co-written with GPT.

The Framework Behind It: Purpose, Influence, Equity

This strategy works because it’s grounded in the Zone of Impact—my 3-part framework for building a career beyond medicine:

Purpose: What energises you?

Influence: Who needs to hear you?

Equity: What value are you building long term?

When your content strategy lives at that intersection, it doesn’t just convert. It compounds.

Conclusion: Don’t Just Create Content. Create Movement.

Your content isn’t just about reach. It’s about resonance. Every post is a chance to say: "Here’s what I believe. Here’s who I serve. Here’s what’s possible."

If you’re a clinician ready to turn credibility into momentum, building content with a custom GPT might be the simplest way to start. Not to outsource your voice—but to sharpen it.
