Have you ever asked ChatGPT for advice on which product to buy? You probably have. And when the AI answered, it mentioned some specific brands and ignored others. Ever wondered why?
It's not about luck. It's about optimization. And it's called GEO: Generative Engine Optimization.
SEO vs GEO: the difference that matters
Traditional SEO optimizes your site to appear in Google's top positions when someone performs a text search. It still works — but it's only half the work needed in 2026.
GEO optimizes your site and content to be cited and recommended by AI models when a user asks a conversational question. ChatGPT, Perplexity, Google AI Overview, Claude, Gemini — these systems are becoming the starting point for millions of purchasing decisions every day.
The practical difference is huge. With SEO, you appear in a list of results and the user decides whether to click. With GEO, the AI recommends you directly as the answer to the user's question — with much higher levels of trust and purchase intent.
How AI models choose what to cite
AI models don't index the web in real time like Google does. They're trained on large amounts of text, then updated periodically with new information. But when they answer questions, they also use real-time web search tools.
What do they look for when recommending a product or service? Mainly three things:
Topical authority: are you recognized as an expert in your field? Are there in-depth content pieces on your site that cover the topic comprehensively? Are there other authoritative sites citing or linking to you?
Trust signals: do you have verified reviews? Case studies with measurable results? Concrete data that backs up what you claim? AIs are programmed to cite reliable sources, not to amplify empty marketing.
Machine-readable structure: are your contents structured so an algorithm can understand them easily? Have you implemented schema markup? Do your pages answer specific questions directly?
The 5 GEO optimizations you need to do now
1. Complete and updated schema markup. Organization, Person, Product, Review, FAQ, LocalBusiness — every page on your site should have the appropriate JSON-LD markup. This isn't optional in 2026: it's how you tell machines who you are and what you do.
2. Content in question-answer format. AIs answer questions. Your content must do the same. Every product page should address the most common questions a potential customer asks. Every blog post should cover a topic comprehensively and exhaustively.
3. Build citable authority. Mentions in industry media, interviews, guest posts on authoritative sites — everything that increases your online presence beyond your own website. AIs preferentially cite sources that are also cited by others.
4. Optimize for conversational searches. People don't ask AIs "running shoes Nike" — they ask "what's the best running shoe for someone with knee problems with a budget of 150 euros?". Your content must answer these long, specific questions.
5. Speed and technical accessibility. AI crawlers, like Google's, reward fast and technically correct sites. This means optimized Core Web Vitals, semantic HTML structure, alt text on images, logical internal links.
The time is now
SEO took years to become mainstream. Everyone remembers that fifteen years ago it was possible to rank with minimal effort. Those who did it back then built enormous competitive advantages.
GEO is at the same stage today. Most companies still don't know what it is. Whoever starts now builds an advantage that will be very difficult to close in two years, when everyone understands how important it is.
