Optimising your website for ChatGPT and other AI-driven search tools is becoming increasingly important as these technologies reshape how users find and interact with information online.
Google may still dominate in traffic, but ChatGPT is quietly driving qualified clicks and surfacing only the most relevant answers.
This guide combines real-world testing, strategic SEO frameworks, and tactical implementation steps to help your content show up in ChatGPT responses.
What Does source=chatgpt.com Actually Mean?
If you’ve seen source=chatgpt.com in your analytics or clicked on one of those links, it means someone landed on your site after ChatGPT cited you.
OpenAI has begun surfacing links in its responses, and those links are trackable.
It may seem like a small detail, but it’s a sign of a broader shift toward answer-level discovery instead of just page-level ranking.
Can Your Brand Be Cited in ChatGPT Answers?
Yes, but only if your content meets specific criteria.
Early versions of ChatGPT rarely returned company names unless prompted precisely. With GPT-4o and ChatGPT Search, that has changed. Now, your business can be:
- Cited as a trusted source
- Linked directly in ChatGPT’s answers
- Clicked as a result of high-intent queries
The opportunity is real, and the competition is growing.
GPT-4o Changed the Game. Here’s How
Unlike older versions such as GPT-3.5, GPT-4o offers:
- Real-time browsing
- Fewer, cleaner links
- Clearer citations
It draws from Bing’s index and prioritises content that is current, reliable, and easy to understand.
We tested dozens of prompts and reviewed what got cited. From that, we developed the Five Pillars of ChatGPT Visibility.

ChatGPT vs Google: Two Systems, One Strategy
| ChatGPT | ||
|---|---|---|
| Traffic Volume | 130B+/month | ~3.7B/month |
| Ranking Basis | Keywords, links, freshness | Mentions, clarity, citations |
| Output Style | SERPs with ads/snippets | One structured answer |
| Best For | Volume and commercial terms | Specific questions, answer trust |
Key Point: You do not have to choose. Optimise for both.
Final Thoughts: Search and AI Are Converging
Ranking alone is no longer enough.
To stay visible, your brand needs to be recognised as the best possible answer.
SEO is not becoming irrelevant. It is expanding.
To stay competitive:
- Combine technical optimisation with question-based strategy
