Why benchmark in Brazil
Brazilian buyers mix Portuguese and English prompts across global models. Visibility differs by language, category, and which competitors models already cite from local media, marketplaces, and review sites.
MencionAI is built for this market: primary audience is marketing and growth teams in Brazil measuring ChatGPT, Perplexity, Gemini, Claude, DeepSeek, and Grok.
Example category prompts (anonymized)
Use buyer language, not brand slogans:
- “Melhor CRM para PME no Brasil”
- “Alternativa ao [competitor] em português”
- “Best payroll software for companies in Brazil”
- “[Category] vs [competitor] for ecommerce”
Run the same set weekly so movement is attributable to content and entity work — not prompt drift.
Benchmark protocol
- Prompt set — 10 buyer-intent questions in PT-BR and EN.
- Model coverage — ChatGPT, Perplexity, Gemini, Claude, DeepSeek, Grok (same settings each run).
- Score visibility 0–100 — brand mentioned, recommended, or linked in the synthesized answer.
- Share of voice — your mentions divided by total brand mentions vs top five competitors.
- Action plan — map citation gaps to comparison pages, FAQ anchors, and
llms.txtupdates.
Reading the results
A low score with high competitor share usually means missing comparison content or weak entity signals — not a single meta-tag fix. Re-run weekly after shipping plan-of-action items.
FAQ
Do I need English pages? Often yes for B2B categories; still prioritize PT-BR pages AIs can cite for local buyers.
Is SEO enough? Strong SEO helps, but GEO measures presence inside AI answers — a different surface.

FAQ
Is GEO a replacement for SEO?
No. SEO ranks links on a results page. GEO measures whether your brand is cited inside AI answers on ChatGPT, Gemini, Claude, Perplexity, Grok, and DeepSeek.
What should we publish first for AI citations?
Comparison pages, FAQ hubs with stable anchors, llms.txt, and Organization schema — then re-scan the same prompts.
What is E-E-A-T and how does it help AI citations?
Google Search Central describes E-E-A-T as experience, expertise, authoritativeness, and trustworthiness — trust first. Named authors, first-hand experience, and citations to official docs help people judge who stands behind the page. Structured data is not required for AI Overviews, but Article, Person, and Organization markup still help Search understand the author and publisher.
Should Brazilian brands optimize in Portuguese, English, or both?
Both. Brazilian B2B buyers mix PT-BR and English prompts. Publish citable PT-BR pages first, keep stable English canonicals for global models, and measure ChatGPT, Gemini, Claude, Perplexity, Grok, and DeepSeek in Brazil.
