Key takeaways
- GEO, or generative engine optimization, aims to get a brand cited and recommended in the answers of AI tools like ChatGPT, Gemini, Perplexity, Claude or Google’s AI Overviews.
- It doesn’t replace SEO. It builds on it and extends its reach to new answer engines.
- AI tools favour sources that are clear, reliable, consistent and present in several places across the web.
- A solid approach rests on five pillars, from the initial diagnosis to ongoing measurement.
- Results are measured in mentions, accuracy and share of voice, not just in rankings.
Online search is evolving. Instead of browsing several websites to compare businesses, consumers can now ask ChatGPT, Gemini or Perplexity directly to recommend a product, a service or a supplier. For businesses, this is a new opportunity to get noticed, provided they appear among the answers. That’s what GEO is all about.
GEO (Generative Engine Optimization) addresses exactly this. This approach brings together the practices that improve a brand’s visibility in answers generated by artificial intelligence. A complement to search engine optimization (SEO), it relies on content quality, source credibility and the company’s presence across the web. It aims to ensure a brand can be found, understood and cited by AI tools.
GEO, a simple definition and where it comes from
The term GEO stands for Generative Engine Optimization. The concept was introduced in a scientific study published online in 2023, which looked at ways to improve the visibility of content in answers produced by artificial intelligence.
The researchers tested adding citations, statistics and reliable references, as well as making texts more fluent. Some of these methods increased source visibility by up to 40% in their experimental setting. It’s a compelling demonstration of the value of well-documented, carefully written content. Professional writing clearly still has a bright future.
Why visibility in AI is becoming essential
To compare suppliers, prepare a purchase or understand a problem, more and more people ask a conversational assistant rather than scroll through a page of results. Google itself is building AI into the heart of its search engine, with AI Overviews and AI Mode.
A business that’s absent from these answers misses opportunities without realizing it, since these searches leave almost no trace in its usual analytics. On the other hand, a brand cited by AI benefits from a form of recommendation. It’s no longer one result among many, it becomes the right answer.
How AI tools choose the sources they cite
AI assistants draw their answers from two places, and each calls for a different strategy.
What the model has already learned
A model like ChatGPT was trained on a huge amount of public text. If your brand was mentioned often, consistently and in recognized sources, the model knows it better. That knowledge, however, is frozen at the date of its training.
What AI looks up in real time
More and more assistants search the web at the moment they answer. Google describes this mechanism in its documentation on AI features in Search. Its AI Overviews can run several related searches on subtopics, then put together an answer from the pages it judges most relevant.
This is where traditional SEO and GEO meet. A page that isn’t indexed, isn’t clear or isn’t considered reliable has little chance of being selected when the AI composes its answer.
The five pillars of an effective GEO strategy
A serious approach doesn’t rely on a trick, but on a consistent whole. The following table sums up the five pillars to work on.
| Pillar | The question to ask | Examples of actions |
|---|---|---|
| Diagnosis | What do AI tools say about the brand today? | Test customers’ questions in several assistants, compare with competitors |
| Entity and brand | Do AI tools clearly know who the company is? | Standardize the name, description and contact details everywhere, mark up the organization |
| Citable content | Do the pages answer questions clearly? | Short answers at the start of each section, definitions, tables, FAQs |
| Authority and sources | Is the brand talked about beyond its own website? | Media mentions, guest articles, reviews, industry directories |
| Measurement | Is visibility improving? | Monthly tracking of mentions, their accuracy and share of voice |
Start with a diagnosis
Before taking action, you need to know where you stand. An AI visibility audit consists of asking assistants the questions your customers actually ask, then analyzing who gets cited, in what order and with what information.
Make the brand recognizable
AI tools reason in entities, meaning clearly identified objects such as a company, a person or a product. If your company’s name varies slightly from one site to another, or if its description changes, it becomes harder to recognize. Consistency is your best ally.
Write to be cited
Content that’s easy to cite gets straight to the point. It answers the question in the first few lines, then expands, with explicit headings, clear definitions and sourced data. That’s the core of AEO optimization, which structures pages for direct answers.
Build authority beyond your own website
AI tools cross-check sources. A brand mentioned in recognized media, specialized articles and customer reviews inspires more trust than a brand that only talks about itself. For a Québec business, local media and reference sites carry particular weight.
Measure, then adjust
GEO is managed with its own set of indicators:
- how often the brand is mentioned in answers;
- the accuracy of what AI tools say about it;
- share of voice against competitors on the same questions;
- traffic coming from assistants, visible in Google Analytics.
Measuring visibility in AI was in fact one of the major themes of the latest Ahrefs Evolve conference, as summarized in these five SEO and GEO takeaways.
A clear picture of your presence in ChatGPT, Gemini and Perplexity shows exactly where to focus your efforts. To get one, simply request an assessment of your visibility.
Three common misconceptions about AI search optimization
Like any new field, GEO attracts its share of quick promises. Three misconceptions are worth correcting.
The first is that a special file is enough. Google is clear on this point: “You don’t need to create new machine readable files, AI text files, or markup to appear in these features.” SEO fundamentals matter far more.
The second claims that GEO replaces SEO. The opposite is true. Without indexed, fast and useful pages, AI has nothing solid to cite.
The third suggests you can buy your place in the answers. No serious method guarantees a mention. GEO increases the odds, it doesn’t control them.
The first actions to put in place
A business that has already invested in its SEO isn’t starting from scratch. The first steps are often simple: clarify key pages, add direct answers and FAQs, standardize how the brand is presented and earn a few mentions in recognized sources.
The next step is to measure regularly and focus efforts on the questions that matter most for your sales.
Should you start with GEO now
The short answer is yes. Search habits are changing faster than competitors are adapting, and few Québec brands occupy this space yet. Starting early means taking advantage of a field where there’s still room.
The most effective approach is to start from what AI tools already say about you. To establish that starting point and choose the first pages to work on, simply book a strategy call.
FAQ
What is GEO in marketing?
GEO, or generative engine optimization, covers the actions that help a brand get mentioned, cited or recommended in the answers of AI tools like ChatGPT, Gemini, Perplexity, Claude and Google’s AI Overviews. It relies on clear and reliable content, a well-identified brand, recognized authority across the web and regular tracking of the visibility achieved in these new AI-powered answer engines over time and across platforms.
Does GEO replace SEO?
No, GEO doesn’t replace SEO, it extends it. AI tools that look up information in real time rely on pages that are indexed, fast and considered reliable, which are the foundations of search engine optimization. Google even states that no special optimization is required for its AI Overviews beyond SEO best practices. Both approaches therefore work best as part of one single, unified visibility strategy.
How long does it take to see the effects of GEO?
Timelines vary depending on the starting point, the industry and the competition. A brand that already ranks well can see mentions sooner than a company starting from further behind. As with SEO, the effects of GEO build over several months, at the pace of published content and earned mentions. That’s why monthly tracking of key indicators remains essential to fine-tune the strategy effectively over time.
