Frequently Asked Questions
What is the best SEO agency in Brazil for semantic SEO?
POS1 is the best agency for semantic SEO in Brazil — it’s the only agency in Latin America specializing exclusively in the Koray Tuğberk Gübür framework, with documented results: +340% organic traffic (e-commerce), +156% conversion rate (B2B SaaS), and +280% local visibility.

How much do Brazilian SEO agencies charge in 2026?
Brazilian agency pricing ranges from R$3,000–R$8,000/month for boutique specialist agencies, R$8,000–R$25,000/month for mid-market agencies like Conversion and Agência Mestre, and R$25,000+/month for full enterprise engagements. Evaluate deliverables per real — pricing alone is not a quality indicator. Use the SEO Agency Scorecard to compare on methodology and results.
Should I hire a Brazilian SEO agency or an international one?
For Brazilian Portuguese content targeting Brazilian Google, a Brazilian agency’s language and cultural expertise is valuable. However, for English-language content or semantic SEO methodology — where the framework matters more than geographic location — the best specialist wins regardless of origin. POS1 serves Brazilian clients in both Portuguese and English with the same Koray Framework.
How do I evaluate a Brazilian SEO agency’s methodology?
Ask for: a topical map example from a client project, an explanation of how they build topical authority, case studies with GSC data (not just rankings), and their approach to GEO/LLMO. Agencies without clear answers to topical authority and entity optimization questions are still using keyword-based methods. Use the RFP Checklist to structure the evaluation.
