GEO & AEO: The New AI Search Optimization in 2026

GEO & AEO: When Artificial Intelligence Redefines Search

You've probably noticed a major shift in how people search for information in 2026. More and more of your future clients no longer type "photographer Geneva" into Google. They ask ChatGPT, Gemini, or Perplexity directly. And the answer they get doesn't list 10 blue links: the AI directly recommends a provider, with their name and URL.

Welcome to the era of GEO (Generative Engine Optimization) and AEO (Answer Engine Optimization). As the founder of Altio, a web agency in Geneva, I can tell you: this is the most important change for search since mobile-first.

What Is GEO Exactly?

GEO (Generative Engine Optimization) refers to all techniques that allow a website to be cited, referenced, and recommended by generative AIs like ChatGPT, Gemini, Perplexity, Claude, and other AI assistants.

GEO and AEO: Two Sides of the Same Coin

AEO (Answer Engine Optimization) is GEO's cousin. While GEO targets generative AIs (ChatGPT, Perplexity), AEO targets Google's direct answers: featured snippets, "People Also Ask", and especially AI Overviews (Google's AI-generated summaries at the top of results).

In March 2026, Google AI Overviews are deployed in most French-speaking markets. This means that even on Google, the answer to a query is often AI-generated.

The good news: both reinforce each other. A site optimized for GEO will also naturally rank better for AEO. The fundamentals are the same: structured, factual, expert, up-to-date content.

A Concrete Case Proving GEO's Impact in Switzerland

The website aphotographie.ch, a professional photographer based in Switzerland, has signed contracts with clients who discovered her via ChatGPT. Not just inquiries: real signed mandates, obtained because ChatGPT recommended her as a trusted photographer in Geneva.

This isn't theory. Our clients in Swiss Romandy are already generating revenue through generative AIs. And this trend is only accelerating.

How Does GEO Work? The 7 Pillars

1. The llms.txt File: Your Business Card for AIs

The llms.txt file is the equivalent of robots.txt, but for AIs. At Altio, we were among the first in Swiss Romandy to implement this file. See ours in action: altio.ch/llms.txt and altio.ch/llms-full.txt.

2. Schema.org Structured Data

Structured data (JSON-LD) is essential for GEO and AEO, helping AIs understand who you are, what you offer, and where you're located.

3. E-E-A-T Content

AIs favor sources that demonstrate real expertise: Experience, Expertise, Authoritativeness, and Trust.

4. Content Clarity and Structure

AIs analyze your site's semantic structure. Well-structured content with hierarchical headings, bullet points, and tables will be better understood and cited.

5. Factual, Citable Information

AIs love factual data: prices, timelines, features, comparisons. The more factual your content, the more it will be cited.

6. Internal Linking and Content Depth

A site with rich internal linking and deep content is perceived as more authoritative by AIs.

7. Content Freshness

AIs favor recent, updated content. A 2024 blog post will be cited less than a 2026 article with equivalent content.
