We all know AI assistants can help with marketing tasks. But, here’s what most people are missing: Using AI as a prompt engineer is where the real productivity gains happen.
I’ve been experimenting with this approach for months, and the results are mind-blowing. Instead of crafting prompts from scratch every time you need help with a campaign or strategy, you can use AI to build an entire library of expert-level prompts that work.
The best part? It works across every area of marketing and scales with whatever you‘re working on. Below, I’m going to share the single AI prompt that will create an expert-level library of marketing prompts. With it, you can transform how you approach marketing work entirely. Let’s dive in.
This One Prompt That Will Make You a Marketing Master
To get this prompt going, the first thing I do is open up ChatGPT and tell it to act like a prompt engineer, expert marketer, or strategic operator. Then, I give it a task:
- “When I give you any kind of marketing discipline (e.g., SEO, paid media, lifecycle), create a prompt library designed by an elite marketer in that field.”
For the deliverables, I tell ChatGPT the format I want, including a summary of how top marketers in this discipline think, what drives results, and how they scale their work. And then, I include instructions on how to create the prompt library.
The full prompt is below for you to see. When I run it, ChatGPT comes back with ten prompts that I can just copy and paste. And, each prompt is based on the thinking of an elite marketer in the field. So, basically, it’s accumulating tactics from successful brands and giving me prompts from that company’s perspective.
Let me give you an example of how this works. After I put in the prompt, ChatGPT will ask me what discipline I want to use. If I say SEO, it first gives me a list of Winning Mental Models, citing the best tactics from the best brands. Here’s what ChatGPT generated:
- The importance of “topic clusters,” citing HubSpot, with the lesson, “build depth-first content silos to signal topical expertise to Google.”
- The idea of “velocity over volume,” citing Grow & Convert, with the lesson, “80% quality at 5X speed wins vs. perfectionism.”
- Six other tactics from elite-level marketers that I can review before I dive into the prompt library.
Then I get a ready-made list of ten prompts that takes the above tactics and develops strategies that I can recreate. With the SEO example, the first prompt I get is:
- Cluster Plan for a Core Topic – “Act like a senior SEO strategist at HubSpot. I want to rank for [employee engagement]. Build a topic cluster with: (1) a pillar post, (2) five cluster articles, (3) intent tags, and (4) internal link structure.”
This prompt is ready to use just by changing the keyword in brackets to whatever I want to rank for. The output also tells me why this fits and how HubSpot would use this tactic. I then get nine more prompts with the same level of detail that I can plug into my AI assistant right now.
This example was for SEO, but I could do the same thing for product marketing or brand marketing, and I would get entirely different results and prompts. It’s just going through and asking, who are the elite marketers in the world? And, what AI prompts would those people use?
The great thing is that you can use this for any tactic to automate your marketing. Just copy the prompts and start to build a library that’s relevant for you and your team.
The Prompt
Act as: A prompt engineer, expert marketer, and strategic operator.
Task: When the user gives you any kind of marketing discipline (e.g., SEO, paid media, Lifecycle), create a prompt library designed by an elite marketer in that field.
Your deliverable (in Markdown):
- Title — “
— AI Prompt Library for Marketers” - Summary (≤ 100 words) — How top marketers in this discipline think, what drives results, and how they scale their work.
- Winning mental models
- List 5-10 key strategies or operating principles used by elite marketers in this field. For each, include: a name (e.g., “Content-Audience Fit”); a 1-line description; a practical, bite-sized lesson; a source or citation (Operator + Year, or company if applicable).
Prompt library — exactly 10 actionable prompts. Each must include:
- Prompt <#> —
- Why this fits: (≤ 25 words — explain why this prompt reflects cutting-edge thinking in this area.)
- How they’d use it: (How the marketer would deploy it in a real-world workflow. Include tool or channel if relevant.)
Style
- Use clear, modern marketing language.
- Prioritize tactics that *scale*, not fluff.
- Be concise, punchy, operator-grade.
Sources
- Use examples, operators, or results from trusted sources post-2015 (e.g., Growth.Design, Reforge, Demand Curve, HubSpot blog, etc).
Why It Works
This one AI prompt works because it takes the brain power of the best people in the world and turns it into easily accessible knowledge. By telling you what elite marketers do in their space, you can replicate their tactics.
