When I first learned about ChatGPT late last year, I was very certain it would turn out to be just one more buzzed about technology that would soon pass in a couple of months. But I was wrong, and two years down the line, I find myself using it nearly every day in my digital marketing work and it has really transformed my approach to the whole process.
But here’s the thing. Most marketers are either not using ChatGPT at all or are using it very poorly. They plug in a very general prompt and receive an equally general response and don’t understand what went wrong. Here comes this guide that tries to make things right. I will show you what ChatGPT is all about, what tasks it is able to complete, and how it can benefit your marketing.
What Is ChatGPT?
ChatGPT is an AI chatbot developed by OpenAI. It is built on a large language model, which means it has been trained on an enormous amount of text from the internet, books, and other sources. The result is a tool that can read your instructions and generate human-sounding text, answer questions, summarise documents, write code, and much more.
You access it through a simple chat interface at chat.openai.com. You type something, it responds. The free version (GPT-3.5) is capable for basic tasks, but the paid version — ChatGPT Plus at $20 per month — gives you access to GPT-4, which is significantly more accurate, more nuanced, and better at following detailed instructions.
For marketers, that $20 is one of the best value tools you can pay for every month.
What ChatGPT Is Good At (And What It Is Not)
Before diving into specific uses, it is important to be honest about what this tool can and cannot do.
What it is genuinely good at:
- Generating first drafts of content quickly
- Brainstorming ideas when you are stuck
- Rewriting or improving existing text
- Summarising long documents or research
- Writing different versions of the same message (A/B testing copy)
- Answering questions about marketing concepts
- Creating outlines and content structures
What it is NOT good at:
- Knowing what happened after its training cutoff date (its knowledge has a limit)
- Replacing real human experience or genuine expertise
- Producing content that is automatically SEO-optimised
- Being 100% factually accurate — it can and does make mistakes
- Replacing a skilled human writer for high-stakes content
Understanding these limits is what separates marketers who get real value from ChatGPT and those who are frustrated by it.
How Marketers Can Actually Use ChatGPT in 2025
Here are the specific ways I use ChatGPT in my own marketing work — with real examples of the kinds of prompts that actually work.
Writing First Drafts of Blog Posts and Articles
This is probably the most common use — and when done right, it works well. The key is never asking ChatGPT to “write an article about X” and publishing whatever comes out. That produces generic, shallow content that neither readers nor Google will value.
Instead, I give it a detailed brief. Here is an example of a prompt that works:
“Write a 1,500-word blog post for digital marketers about how to use Instagram Reels to grow a small business. The tone should be practical and conversational, not corporate. Include specific tips, real-world examples, and a clear structure with H2 and H3 headings. Assume the reader knows basic social media but is new to Reels.”
That kind of specific prompt produces something much closer to publishable — though I always edit, add my own experience, and fact-check before publishing.
Writing Social Media Captions and Ad Copy
This is where ChatGPT saves me the most time. Instead of staring at a blank screen trying to write five different versions of a Facebook ad headline, I ask ChatGPT to do it in seconds.
Example prompt:
“Write 10 different Facebook ad headlines for a digital marketing agency targeting small business owners in the UK. The offer is a free 30-minute SEO audit. Make some of them curiosity-driven, some urgency-driven, and some benefit-focused.”
You get 10 solid options in about 10 seconds. You pick the best two, tweak the wording, and test them. That process used to take me 20 minutes. Now it takes two.
Email Marketing
I use ChatGPT to write email subject lines, preview text, and full email body copy. Subject lines especially — writing 20 variations to A/B test used to be a grind. Now I prompt ChatGPT with the email topic and ask for 20 subject line options in different styles, and I have them in under a minute.
For full email copy, the same rule applies as with blog posts — give it a detailed brief. Tell it who the audience is, what action you want them to take, what the tone should be, and what the key benefit is. The more context you give, the better the output.
SEO Keyword Research and Content Ideas
ChatGPT is not a replacement for proper keyword research tools like Ahrefs or Semrush — it does not have access to real search volume data. But it is excellent for brainstorming topic clusters and finding angles you might not have thought of.
Example prompt:
“I run a blog about AI tools for digital marketers. Give me 30 blog post ideas that cover beginner questions, tool comparisons, how-to guides, and common mistakes. Focus on topics that someone new to AI tools would actually search for.”
I do this regularly and it surfaces article ideas I genuinely would not have thought of myself. I then take those ideas and run them through a real keyword tool to check the actual search volume before writing.
Repurposing Existing Content
One of my favourite uses. If I have written a long blog post, I can paste it into ChatGPT and ask it to:
- Turn it into a Twitter/X thread
- Write a LinkedIn post summarising the key points
- Create three short Instagram captions based on the main ideas
- Write a script for a short YouTube video on the same topic
This multiplies the value of every piece of content I create without having to start from scratch each time.
Customer Research and Persona Building
I use ChatGPT to help me think through target audience personas. I describe a business and its customers, then ask ChatGPT to help me articulate the common pain points, objections, goals, and language that audience uses. This is useful for sharpening ad copy, email campaigns, and content strategy.
It is not a replacement for real customer interviews or data — but it is a fast way to structure your thinking and identify angles you might be missing.
Tips for Getting Better Results from ChatGPT
After using this tool daily for over a year, here is what I have learned about getting consistently good output:
Be specific. Vague prompts produce vague results. The more detail you give about your audience, goal, tone, and format, the better.
Give it a role. Starting a prompt with “You are an experienced digital marketing copywriter…” helps frame the response appropriately.
Ask for options. Instead of asking for one headline, ask for ten. More options means more chances of finding something great.
Edit everything. ChatGPT is a first draft tool, not a finished product tool. Always read through, edit, add your own voice and experience, and fact-check anything that matters.
Use it iteratively. If the first response is not right, do not start over — just tell it what to adjust. “Make it shorter”, “make the tone more casual”, “focus more on the benefit rather than the feature” all work well as follow-up instructions.
Is ChatGPT Worth It for Marketers?
Yes — but only if you use it properly. The free version is a reasonable starting point for occasional use. If you are using it regularly for marketing work, ChatGPT Plus at $20/month pays for itself quickly in time saved.
The marketers I have seen get the most from it treat it as a capable assistant, not a magic solution. They give it good briefs, they edit the output, and they add their own expertise on top. The ones who are disappointed are usually the ones who expected it to do everything perfectly without any guidance.
Used well, ChatGPT is one of the most practical AI tools available to marketers in 2025. It will not replace you — but a marketer who knows how to use it well will have a real advantage over one who does not.
Final Thoughts
ChatGPT has become a genuine part of my marketing workflow, not because it does everything for me, but because it handles the repetitive and time-consuming parts faster than I ever could. That frees me up to focus on strategy, creativity, and the things that actually require human judgment.
If you have not seriously tried it yet, start with something small — ask it to write five email subject lines for your next campaign, or brainstorm 20 blog post ideas for your niche. You will see the value immediately.
And if you are already using it but not getting great results, the fix is almost always in the prompt. Be more specific, give more context, and treat it like briefing a junior writer — not pressing a magic button.
