Quick answer: generative engine optimization (GEO) is the practice of helping AI answer engines such as Google AI Overviews, AI Mode, ChatGPT, Gemini and Perplexity find, understand and mention your business accurately. It builds on SEO and adds answer-first content, verifiable facts, consistent business details and mentions on trusted websites.
More people now ask AI tools for recommendations and explanations instead of scrolling through search results. This guide explains how GEO works and the practical steps a Canadian business can take, without shortcuts or false promises.
What is generative engine optimization?
Generative engine optimization is the work of improving how often and how accurately your business appears in AI-generated answers. The term was popularized by a 2023 research paper, “GEO: Generative Engine Optimization”, by researchers from Princeton University and other institutions.
In their experiments, adding elements such as citations to sources, relevant quotations and statistics improved a source’s visibility in generative engine responses by up to 40%. The lesson for businesses is simple: content that is specific, sourced and easy to quote is more likely to be used.
Is GEO different from SEO?
GEO and SEO overlap far more than they differ. For Google’s AI features, Google says there are no extra technical requirements: a page needs to be indexed and eligible to appear in Search with a snippet. Strong SEO is therefore the foundation of GEO.
| Focus | SEO | GEO |
|---|---|---|
| Goal | Rank pages in search results | Be cited or mentioned in AI answers |
| Content | Helpful pages for each search | Clear, quotable answers and facts |
| Signals | Links, relevance, page experience | Also brand mentions, consistency, reputation |
| Measurement | Rankings, clicks, leads | Mentions and descriptions in AI answers, plus leads |
How do AI answer engines choose sources?
Each system works differently, but most retrieve web pages related to a question and then summarize them. Pages that clearly answer the question, come from trusted sources and agree with other reliable information are easier to use. If your business details conflict across the web, AI tools may describe you inaccurately or not at all.
8 practical steps to improve your GEO
- Make sure your site can be crawled and indexed. Check Search Console and avoid blocking important pages.
- Open every section with a direct answer. One or two clear sentences, then the detail.
- Add facts and cite sources. Use statistics and references from authoritative organizations, and keep them current.
- Answer real questions in FAQs. Use the wording customers actually use.
- Describe your business the same way everywhere. Name, services, location and policies should match on your site, Google Business Profile, directories and social profiles.
- Earn genuine mentions. Industry directories, local media, partners and review sites help AI tools recognize your brand.
- Use structured data that matches the page. Organization, Service and FAQ schema help search engines understand your content.
- Test and track. Ask AI tools the questions your customers ask and record whether and how you are mentioned.

What GEO cannot do
No one can guarantee that an AI tool will recommend your business. AI answers change between questions, users and updates. Be cautious of anyone selling instant AI rankings, special files that “force” AI citations or hidden text aimed at chatbots.
Google has said that no special AI text files or markup are needed for its AI features. Some other AI tools read files such as llms.txt, but they are not a substitute for helpful content and a trusted brand.
How to measure GEO progress
- Keep a list of 10 to 20 prompts customers might ask, such as “best web design company in Calgary for restaurants”.
- Test them monthly in the main AI tools and note mentions, descriptions and competitors.
- Track branded searches and direct enquiries in Search Console and GA4.
- Fix inaccurate descriptions at their source, such as an outdated directory listing.
Google AI Mode reached Canada in August 2025, which we covered in Google AI Mode is now in Canada. To put GEO into practice, see our AI search optimization (GEO) service and our content marketing service.

Frequently asked questions
What does GEO stand for in marketing?
GEO stands for generative engine optimization: improving how AI answer engines such as ChatGPT, Gemini, Perplexity and Google AI Overviews find, understand and mention your business.
Does GEO replace SEO?
No. GEO builds on SEO. Google says pages need to be indexed and eligible for regular Search to appear in its AI features, so technical SEO and helpful content remain the foundation.
Can anyone guarantee my business appears in ChatGPT?
No. AI answers vary by question, user and system updates, and no agency controls them. A trustworthy provider improves the signals AI tools rely on and reports progress honestly.
Do I need an llms.txt file?
Google says no special files are needed for its AI features. Some other AI tools may read llms.txt, so it can be a small extra, but it does not replace helpful content and accurate business information.
