Flowup Agency
Flowup Agency is a Brazilian digital marketing agency founded in 2011 and headquartered in Sao Paulo, working at the intersection of strategy, technology, SEO and artificial intelligence. It publishes separate service pages for SEO, GEO and AEO alongside data-driven PR, growth content and WordPress development.
It is one of the few Brazilian agencies with three distinct published service pages for SEO, generative engine optimization and answer engine optimization, plus a combined consulting page. The site lists a Sao Paulo street address and a registered company number.
You want AI search work broken out as named, separately scoped disciplines rather than bundled invisibly into an SEO retainer.
- Publishes distinct SEO, GEO and AEO service pages, so the scope of each discipline is documented before a sales call
- Documented founding year, named founders, registered company details and a street address in Sao Paulo
- Runs a named in-house methodology with its own published page
- No pricing or project minimum is published
- The agency states it works fully remotely by video call and messaging, so on-site collaboration is not the default
Agencia Mestre
Agencia Mestre is a Sao Paulo digital marketing agency founded in 2008 that works across SEO, inbound marketing, paid media and business intelligence. It runs a dedicated GEO consulting service aimed at brand visibility inside ChatGPT, Gemini, Claude, Perplexity and Google AI Overviews.
Its GEO consulting page defines generative engine optimization and states plainly that GEO, AEO and AI search are different names for the same challenge, which the agency treats as one discipline built on SEO foundations. The site lists a Sao Paulo office address and operation since 2008.
You want a long-established Sao Paulo agency that folds AI search visibility into a broader inbound and paid acquisition program.
- Operating since 2008, one of the longest running SEO specialists in Brazil
- The GEO page lists concrete deliverables including competitor-benchmarked AI presence diagnosis and monthly citation monitoring
- Publishes a physical Sao Paulo office address rather than operating anonymously
- No pricing or project minimum is published, and the site routes all enquiries to a quote request form
- The service list spans far beyond search, so confirm how much of the team is dedicated to SEO and GEO
onSERP Marketing
onSERP Marketing is a Rio de Janeiro agency that has combined SEO and website development since 2020, working from an office in Barra da Tijuca. Its SEO for AI service covers generative engine optimization across ChatGPT, Perplexity, Gemini, Copilot and Google AI Overviews.
Its SEO for AI page defines GEO in full and states that the agency handles answer engine and generative engine work within the same service. The site publishes a street address and landline, and lists partner status with major search tooling vendors.
You want a Rio de Janeiro team that pairs SEO and AI search work with in-house web and ecommerce development.
- Publishes a full street address and landline, unusual among smaller Brazilian agencies
- The GEO page spells out a three-step method: map the questions the audience asks AI tools, produce citable content with structured data, then monitor where the brand appears
- Lists named Brazilian clients on its own site
- Describes itself as a lean team, which may limit capacity for very large enterprise programs
- No pricing is published, although the contact form asks prospects to select a monthly budget band
How we ranked these agencies
- How central answer-engine work is to the practice, not a bolt-on service line
- Third-party review score on Clutch, GoodFirms or G2 where published
- Named services and a clear, public description of the offer
- Company longevity and team size
- Fit for enterprise versus small and mid-size brands
- Pricing transparency
- Evidence of real, named client work
Every agency listed is real and operating. Founding years, ratings and services come from the agency website or a third-party review platform, verified 2026-09-17. Where a figure is not published, the page says so rather than estimating.
Why work with a AEO agency in Brazil
Brazil is the only market outside North America where an agency publishes three separate service pages for SEO, GEO and AEO as distinct disciplines.
Remote-first is the norm here rather than the exception. Several of the strongest agencies publish no office address at all and operate across many states, so judge them on documented history rather than a street address.
None of the six publish pricing or project minimums. Most route enquiries through a quote request form.
