SEO (Search Engine Optimisation) is the set of techniques that makes a website appear in the top positions on Google without paying for ads. It covers the website's technical foundations, content, user experience and the brand's authority online.
GEO (Generative Engine Optimisation) is the evolution of SEO for the age of artificial intelligence. When someone asks ChatGPT, Gemini, Perplexity or Google's AI mode ‘what is the best marketing agency in São Paulo’, the answer cites a handful of brands and sources. GEO is the work of making your company one of those cited brands.
In short: SEO puts your website at the top of Google. GEO gets your brand cited and recommended by artificial intelligence. An SEO and GEO agency works on both at the same time.
SEO vs GEO: key differences
| SEO | GEO | |
|---|---|---|
| Where it appears | Google and other search engine results | Answers from ChatGPT, Gemini, Perplexity, Claude and Google AI Overviews |
| Objective | Rank pages for keywords | Be cited as a source and recommended as a brand |
| What matters | Relevant content, technical foundations, links and experience | Clear, verifiable information, first-party data, authority and mentions on other sources |
| Ideal format | Complete pages organised by search intent | Direct answers, questions and answers, lists, numbers and structured data |
| How to measure | Rankings, clicks and organic visits | Brand mentions and citations in AI answers |
The two work hand in hand: a website well optimised for Google is also one of the main sources AI consults. Google itself explains how content is used in its AI features in the official documentation AI features and your website.

How it works, step by step
Visibility diagnosis
We analyse where your brand appears today on Google and in AI answers, and where your competitors are.
Keyword and question strategy
We define the terms and questions that bring in customers and organise the website into pages for each intent.
Technical fixes
We adjust speed, indexing, structured data and everything that stops Google and AI from reading the site.
Content and authority
We produce complete pages and articles, backed by real data, and build brand mentions on other sources.
Measurement and progress
We track rankings, visits, enquiries and AI citations, with a monthly report and next steps.
How AI chooses who to cite
Artificial intelligence builds answers from sources it can read and trusts. In practice, the most cited brands tend to have:
Clear, consistent information
Who the company is, where it is, what it does and for whom, written directly and identically everywhere.
First-party, verifiable data
Result figures, case studies with a time period and client, and claims that can be confirmed.
Content in answer format
Frequently asked questions, short definitions, lists and tables that are easy to extract.
Mentions on other sources
Google reviews, rankings, the press and industry directories strengthen trust in the brand.
This very Nume website was built with these practices: structured data, frequently asked questions, complete service pages and an llms.txt file, a proposed standard to help AI understand a website.
