GEO (Generative Engine Optimization) is the set of actions that make an AI answer engine, such as ChatGPT, Gemini, Perplexity or Claude, understand your brand, trust it and cite or recommend it in its answers.
SEO and GEO: what changes
Today your customers search for you on Google and also ask an AI. SEO improves how search engines find and rank you; GEO prepares your content so generative AI systems can understand and cite it. They complement each other and share a foundation: useful, well-structured content.
| SEO | GEO | |
|---|---|---|
| Goal | Appear and rank in the list of results. | Be cited or recommended inside an AI’s answer. |
| Where | Google, Bing and other search engines. | ChatGPT, Gemini, Perplexity, Claude, Copilot and search engines’ AI answers. |
| Key signals | Technology, content, links and user experience. | Clear entities, direct answers, structured data and reliable mentions. |
How AI engines decide what to cite
Answer engines consult web pages, extract passages and compose an answer citing the sources that best explain the topic. In general, they favour pages that:
- are crawlable: they allow access to their bots and load quickly;
- define clearly who you are, what you offer and for whom, using the same words across the whole website;
- answer specific questions with a direct sentence at the start;
- use structured data (schema.org) describing the company, the services and the frequently asked questions;
- are mentioned and referenced in other trusted sources.

Frequently asked questions
What is GEO?
GEO, Generative Engine Optimization, is the optimisation of your content so AI answer engines can understand it and cite or recommend it in their answers.
What is the difference between SEO and GEO?
SEO improves how search engines such as Google find and rank you. GEO prepares your content so generative AI systems can understand it and cite it. They complement each other and share a foundation: useful, well-structured content.
Can appearing in ChatGPT or on Google be guaranteed?
No. Nobody can guarantee it, because they depend on algorithms we don’t control. You work on the signals that do depend on you (technology, content, structure and reputation) and measure progress.
How long does GEO take to show results?
It depends on the starting point, the competition and the actions carried out. Technical changes can be crawled in hours or days; reputation and mentions take longer. After an audit, goals and a timeline are defined.
Should I let AI crawlers access my website?
If you want AI engines to know and cite you, yes. It is controlled in the robots.txt file, bot by bot, and it makes sense to keep out only private or low-value areas, such as the cart or the account area.
What is the llms.txt file?
It is a proposed convention for giving language models a summary of the company and links to its main pages. Not every engine reads it, but it does no harm and helps keep your information consistent. IGLOBALIA’s is at iglobalia.com/llms.txt.
Does IGLOBALIA do GEO for hotels, retail, industry and sports?
Yes. IGLOBALIA specialises in the hospitality, retail, industrial and sports sectors, and applies SEO and GEO to the searches specific to each.
