SEO (Search Engine Optimization) is the set of techniques that makes a website appear in the top positions on Google without paying for ads. It involves the site's technical foundation, content, user experience and the brand's authority across the internet.
GEO (Generative Engine Optimization) 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 few 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 both fronts at the same time.
SEO vs. GEO: key differences
| SEO | GEO | |
|---|---|---|
| Where it appears | Results on Google and other search engines | Answers from ChatGPT, Gemini, Perplexity, Claude and Google AI Overviews |
| Goal | Rank pages for keywords | Be cited as a source and recommended as a brand |
| What matters most | Relevant content, technical foundation, links and experience | Clear, verifiable information, first-party data, authority and mentions on other sources |
| Ideal format | Complete pages organized by search intent | Direct answers, Q&A, lists, numbers and structured data |
| How to measure | Rankings, clicks and organic visits | Brand mentions and citations in AI answers |
The two fronts reinforce each other: a website well optimized for Google is also one of the main sources AI tools consult. 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 assessment
We analyze 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 organize the site into pages for each intent.
Technical fixes

Measurement and progress
We track rankings, visits, leads and AI citations, with a monthly report and next steps.
How AI chooses who to cite
Artificial intelligence tools build answers from sources they can read and trust. 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
FAQs, short definitions, lists and tables that are easy to extract.
Mentions on other sources
Google reviews, rankings, press and industry directories reinforce trust in the brand.
This very Nume website was built with these practices: structured data, FAQs, complete service pages and an llms.txt file, a proposed standard to help AI tools understand a website.
