What is Generative Engine Optimization (GEO)?
Definition
Generative engine optimisation (GEO) is the practice of making your content and brand more likely to be found, understood and cited by AI systems that generate answers, such as ChatGPT, Perplexity, Gemini and Google's AI Overviews, rather than only ranking as a link in traditional search results.

How generative engine optimisation works
When someone asks an AI assistant a question, the system typically searches the web or its index, retrieves a handful of pages and writes an answer, sometimes with citations. GEO focuses on being one of those retrieved and quoted sources. The term was popularised by a 2023 research paper, GEO: Generative Engine Optimization, whose authors reported that certain content changes, such as adding citations, quotations and statistics, could raise a source's visibility in generated answers by up to 40% in their tests.
In practice, GEO builds on solid SEO. Pages need to be crawlable and indexed. Answers should be stated clearly near the top, in self-contained sentences an AI can lift without losing meaning. Facts should be specific and current. Structured data such as schema markup helps systems understand what a page is about, and mentions of your brand across reputable sites signal that others trust you.
Example: a Toronto immigration consultancy publishes a page answering "how long does a Canadian work permit take to process," with a two-sentence answer up top, a link to the official government processing times and a clear note on when the page was updated. That structure makes the page easy for both search engines and AI assistants to cite.
Why it matters for your business
More people now start research by asking an AI assistant. If your business is absent from those answers, competitors become the default recommendation before anyone visits a website. Being cited also builds credibility, because the assistant is effectively vouching for you.
The habits that help GEO, clear answers, verified facts and a strong reputation, also help traditional rankings, so the work is rarely wasted. Our guide on how to get cited by ChatGPT lists the changes that move results, and AI Overviews explains Google's version.
Common mistakes
- Treating GEO as a separate trick rather than an extension of good SEO and good writing.
- Burying the answer under long introductions written for word count.
- Making claims without sources, which gives AI systems no reason to trust the page.
- Blocking AI crawlers by accident in robots.txt or a firewall, then wondering why you are never cited.
- Measuring only traffic, when citations and brand mentions are often the earlier signal.
Frequently asked questions
Is GEO replacing SEO?
No. Most AI answer engines rely on search indexes to find sources, so ranking well still matters. GEO adds attention to how content is quoted, not just how it ranks.
Does an llms.txt file help with GEO?
It may help some tools read your site, but support is inconsistent. Our llms.txt entry explains where it fits.
