ChatGPT and other AI assistants now play two roles in B2B marketing. They are tools your team can use to research, draft and analyse faster, and they are a new place where buyers look for suppliers. This guide covers practical examples of both, what works, what goes wrong and how to measure it.
Updated 30 September 2026. This post replaces our 2023 round-up of ChatGPT marketing case studies, which had dated quickly.
The short version
- As a tool: AI assistants are good at research summaries, first drafts, repurposing and analysis. They are poor at checking facts and sounding like you.
- As a channel: buyers increasingly ask ChatGPT, Perplexity and Google’s AI Overviews for recommendations, so your content needs to be clear and specific enough to be quoted.
- Proof it works: our own client went from 18 to 213 weekly users in 12 weeks after rebuilding its content for AI discoverability.
How B2B teams use ChatGPT in marketing
These are the uses we see pay off most often in B2B marketing teams, including our own:
1. Research and briefing
AI assistants can summarise a topic, list the questions buyers ask and outline the angles competitors have covered. That turns hours of desk research into a starting point in minutes. The output still needs checking against original sources before anything is published.
2. First drafts and outlines
Given a detailed brief, your expertise and examples, an assistant can produce a workable first draft or outline. The value comes from what you put in: generic prompts produce generic content.
3. Repurposing
One strong article can become a LinkedIn post, a newsletter section, a short video script and an FAQ. AI is quick at the reformatting; a human makes sure each version still sounds like the brand.
4. Analysis
Assistants can help make sense of survey responses, sales call notes or search data, spotting themes you can then verify and act on.
5. Editing support
AI is good at catching spelling, grammar and structural gaps. It is not reliable at checking whether a claim is true. See the real cost of fast content for why that matters.
AI assistants as a channel: the example that matters most
The bigger change is on the buyer side. B2B buyers now ask AI assistants to explain problems, compare options and suggest suppliers. If your website is vague, badly structured or hard for AI crawlers to read, you are left out of those answers.
One of our clients, a UK professional services firm, had thousands of monthly search impressions but almost no visitors, with an average position between 50 and 70. After we rebuilt its content around clear, specific answers and a semantic structure that AI systems can follow, the site went from 18 to 213 weekly users in 12 weeks. Read the full case study.
The lesson is simple: the content that gets quoted by AI is the content that answers a real question clearly, shows real expertise and is easy to parse.
What goes wrong
- Publishing unchecked output. Invented statistics and sources damage trust quickly.
- Sounding like everyone else. When every competitor uses the same tools, generic drafts blend together. See why most B2B brands sound the same.
- Ignoring AI visibility. Many teams use AI to write but never check whether AI assistants mention them.
- Putting sensitive data into public tools. Keep client and commercial information out of prompts unless your tools and contracts allow it.
How to measure AI in your marketing
Track two things. First, efficiency: time saved per piece and the quality of the result after editing. Second, visibility: AI referral traffic in your analytics, whether AI assistants mention your brand for your key topics, and branded search growth.
Our AI Visibility and Web Performance Report tracks the visibility side for you every month, from £200 a month. For a one-off view of how AI assistants read your site, start with the AI readiness check.
FAQs
Can ChatGPT write B2B marketing content?
It can produce useful first drafts, outlines and variations, but content that wins B2B buyers needs your expertise, examples and a human edit for accuracy and voice.
How do I get my business recommended by ChatGPT?
Publish clear, specific answers to the questions your buyers ask, make your site easy for AI crawlers to read, add structured data and earn mentions on other trusted sites. Our guide What Is AEO? explains the basics.
Is it safe to use ChatGPT for client work?
Only with care. Avoid entering confidential information into public tools, check your provider’s data settings and verify every fact before publishing.
