ChatGPT
ChatGPT is OpenAI's conversational AI assistant, one of the largest AI search channels worldwide and a primary GEO target.
ChatGPT is OpenAI's consumer-friendly assistant, launched in November 2022 and now one of the largest AI channels globally, with hundreds of millions of monthly users. Under the hood sits a series of LLMs (GPT-4o, GPT-5) augmented with tools like web search, code execution and file reading. For GEO it matters for two reasons: many professionals use ChatGPT as their first search channel, and ChatGPT (in Search mode) actively cites web sources — direct visibility opportunities.
Example
A user with a paid ChatGPT account asks 'which Dutch SEO agencies specialise in crypto?'. ChatGPT performs a web search, reads the pages, and produces an answer with 3–5 citations to individual agency sites. Those cited get both brand exposure and traffic.
Frequently asked questions
How do I get into ChatGPT answers?
Make your page findable for the indexes ChatGPT uses (currently Bing and OpenAI's own crawler), parseable (clear structure, schema markup, TL;DR), and build domain authority. Citations correlate strongly with presence on LinkedIn, Reddit, Wikipedia and large news media.
Is ChatGPT more important than Google for GEO?
Not yet for everyone. Google still holds ~90% of classic search. ChatGPT dominates in professional and technical use. For B2B marketing in fintech/AI/Bitcoin it's now on par with Google.
