What We Do: AEO, GEO, AIO, and Technical SEO for Brazilian Brands
Cortex High Level is a Brazilian agency specialized in positioning brands as the definitive answer in AI search engines — ChatGPT, Google Gemini, Perplexity AI, Claude, Microsoft Copilot, and Google AI Overviews. We operate at the intersection of technical SEO, content strategy, and AI discoverability.
Our service portfolio covers four integrated disciplines: SEO (technical foundation and rankings), AEO (answer engine presence and FAQ optimization), AIO (AI entity building and E-E-A-T development), and GEO (generative engine citation and authority building). These are not sold as separate services — they are delivered as the integrated AI Referral Engine™ methodology.
Why AEO Matters for Brazilian Brands Specifically
Brazilian consumers are among the world's most active AI users. ChatGPT usage in Brazil grew by over 400% between 2023 and 2025. Gemini and Perplexity have significant Brazilian user bases. When Brazilian consumers research professional services, B2B solutions, or high-ticket purchases, they increasingly start with an AI query rather than a Google search.
The brand that is cited in that AI response has a decisive advantage. In our client work, brands consistently cited in AI answers report receiving leads who arrive already familiar with the brand's methodology, already pre-qualified by the AI's explanation of the service, and already further along in the buying decision than traditional SEO leads.
Our Track Record: 47+ Brands in Brazil
Cortex High Level has served over 47 brands across Brazil in sectors including SaaS platforms, professional services, architecture and engineering, fintech, e-commerce, education, and personal branding. Our client roster includes BlackClub, Credits Hub, XScale AI, Flowyis, Rapdyn, Zephmap, and Vyrion, among others.
While each engagement is confidential, the consistent pattern across clients is a significant increase in AI-sourced lead quality within the first 90 days of AI Referral Engine™ implementation, followed by growing branded search volume as AI citations drive users to verify the brand in traditional search.
How to Work With Cortex High Level
Every engagement begins with a free AI presence diagnostic. We query the major AI engines (ChatGPT, Gemini, Perplexity, Claude) with the questions your target customers are asking, and report back exactly how — and whether — your brand appears. This diagnostic identifies specific gaps, competitor positioning, and the opportunity landscape.
From there, we design a custom AI Referral Engine™ implementation plan aligned to your sector, competition level, and growth goals. Engagements are structured as monthly retainers, with minimum 3-month commitment to allow compounding results to develop.
Perguntas frequentes
Is Cortex High Level only for large companies?+
No. While we work with enterprise brands, the AI Referral Engine™ methodology is especially powerful for mid-market and growing brands in Brazil — precisely because the AI citation competition in most Brazilian categories is still low. This means earlier and faster results than equivalent markets in the US or Europe.
Do you work with companies outside Brazil?+
Yes. Cortex High Level serves brands targeting Portuguese, English, and Spanish-speaking markets. Our AI Referral Engine™ methodology is language-agnostic and we have implemented it for international campaigns.
What is the AI Referral Engine™ diagnostic?+
A free assessment in which we query ChatGPT, Gemini, Perplexity, and Claude with the questions your target customers are asking, and report how your brand and competitors appear in the responses. It takes 48 hours and gives you a clear picture of your current AI search presence.
What sectors does Cortex High Level specialize in?+
We have deep experience in SaaS, professional services (law, consulting, finance), architecture and engineering, e-commerce, education and infoproducts, and personal branding. Our AI Referral Engine™ methodology has been refined across all these sectors in the Brazilian market.
How much does AEO/GEO optimization cost in Brazil?+
Cortex High Level packages start from R$2,500/month for foundational AI presence work (technical SEO + AEO content + GEO infrastructure). Full AI Referral Engine™ engagements covering all four pillars (SEO + AEO + AIO + GEO) with monthly content and citation monitoring start from R$5,000/month.
