Most people use ChatGPT like a slightly smarter search engine. They type a vague question, get a vague answer, and wonder why it's not saving them any time.

After two years of using AI daily for my agency and my clients' businesses, here's what I've learned: ChatGPT is powerful, but only if you treat it like a specialist contractor, not a magic button.

This means giving context. Giving constraints. And knowing exactly what you need before you ask.

1. Brand voice prompt (the one I send to every new client)

Before I use ChatGPT for any client work, I feed it a brand voice document. Here's the structure:

You are a marketing writer for [Company Name].

Brand voice: [3–5 adjectives that describe the tone]
We write like: [describe the style — e.g., "a knowledgeable friend, not a professor"]
We never use: [list banned phrases — e.g., "leverage", "synergy", "game-changing"]
Our audience: [1-paragraph description]

Confirm you understand and wait for my first task.

Once you've done this, every output from that session carries the brand's voice. This alone saves hours per week.

2. Content repurposing workflow

This is the workflow I use most. You write one piece of content — say a blog post — and ChatGPT transforms it into 5 other formats:

Here's a blog post: [paste full article]

From this, create:
1. A LinkedIn post (250 words, first-person, no hashtags)
2. 5 tweets that could be posted separately (not a thread)
3. An email newsletter intro (150 words, conversational)
4. 3 ideas for Instagram captions
5. A short YouTube script intro (60 seconds when read aloud)

Keep the tone consistent with the original. Don't add information that isn't in the article.

The key detail: Don't add information that isn't in the article. Without that, ChatGPT will hallucinate statistics and quotes. I learned this the hard way.

3. Audience research (faster than surveys)

This is the use case most people miss. ChatGPT is remarkably good at synthesising what it knows about specific audience segments:

I'm marketing [product/service] to [specific audience].

List:
- Their 5 biggest pain points related to [topic]
- The language they actually use to describe those problems
- The objections they'd raise when considering my product
- Where they get their information (specific publications, podcasts, communities)

Be specific. Avoid marketing clichés.

This isn't a replacement for real customer research. But it's an excellent starting point — and it often surfaces angles you hadn't considered.

4. The one mistake everyone makes

Accepting the first output. ChatGPT's first response is almost always the most generic version of what you asked for. The real output quality comes from iteration: ask it to push harder, get more specific, or take an opposite angle.

My default follow-up: This is too generic. What would a genuinely original version of this look like?

Works every time.

The bottom line

ChatGPT won't do your marketing for you. But it will do the time-consuming, repetitive parts faster than any human could — if you know how to direct it. The people getting the most value out of AI tools right now aren't the ones using the most sophisticated tools. They're the ones who've built clear, repeatable workflows.

Start with one workflow. Run it 20 times. Then add another.
