SEO Agency in Brazil: Building Visibility on Google and AI Search

How an SEO agency in Brazil combines technical optimization, locally relevant content and AI search strategies to make your brand easier to find on Google and in answers from ChatGPT, Gemini and Perplexity.

Choosing an SEO agency in Brazil is different from hiring SEO services in many other markets.

The country has one of the largest connected populations in the world, search behavior that is strongly mobile and regional, and a language, Brazilian Portuguese, that requires more than literal translation.

At the same time, search itself is changing.

Executives and consumers no longer rely only on Google. They also use ChatGPT, Gemini, Perplexity and other AI-powered tools to research problems, compare solutions and identify potential suppliers.

An SEO agency that ignores this emerging discovery layer delivers an incomplete visibility strategy.

GS2 Marketing Digital is a Brazilian digital marketing agency headquartered in São José dos Campos, São Paulo. For more than 15 years, GS2 has developed SEO and content strategies for medium-sized and large companies in Brazil and abroad.

This article explains why SEO matters in the Brazilian market, what makes local search behavior different, how GS2’s methodology works and how traditional SEO can be connected with Generative Engine Optimization, or GEO.

Why Does SEO Matter in Brazil?

Search Engine Optimization, or SEO, is the set of technical, content and authority-building practices used to improve a website’s visibility in unpaid search results.

In Brazil, SEO has particular importance because of the scale and concentration of the market.

According to the TIC Domicílios 2025 survey by Cetic.br and NIC.br, Brazil had approximately 157 million internet users in 2025, representing 85% of the population aged ten or older.

Under the survey’s expanded definition, which also considers people who use mobile internet and internet-dependent applications, the number reaches 163 million people, or 88% of the population.

Search activity is also highly concentrated.

According to StatCounter Global Stats, Google held 88.08% of the Brazilian search engine market in June 2026, compared with 9.43% for Bing.

For companies operating in Brazil, this means that a significant part of the customer research process still happens within the Google ecosystem.

A brand that cannot be found on Google may be absent when potential customers are:

• identifying a problem;
• researching possible solutions;
• comparing suppliers;
• evaluating technical information;
• checking brand credibility;
• preparing to contact sales.

This is particularly relevant for high-value and complex decisions.

Before contacting a supplier, Brazilian buyers may research a B2B software platform, industrial component, school, healthcare provider, financial service or professional service.

Organic search allows the company to be present during that research process.

Unlike paid media, organic visibility does not require payment for every visit. However, SEO still requires continuous investment in content, technical quality, authority and maintenance.

Over time, a strong organic presence can reduce dependence on paid acquisition and continue generating qualified traffic from content and pages already published.

For international companies entering Brazil, SEO also helps establish local credibility before the operation reaches scale.

What Makes SEO in Brazil Different?

SEO strategies created for the United States or Europe may provide useful principles, but they cannot simply be translated and replicated in Brazil.

Five factors help explain why localization is necessary.

Language and Local Search Terms

Brazilian Portuguese differs from European Portuguese in vocabulary, syntax, tone and search behavior.

A Brazilian user searches for “celular,” not “telemóvel,” and may search for “plano de saúde” rather than a literal translation of “private health insurance.”

Translating keywords directly from another market can create pages optimized for terms that Brazilian users rarely search for.

Technical terms and English loanwords also behave differently depending on the industry.

In some markets, Brazilian users commonly search for terms such as:

• CRM;
• software;
• e-commerce;
• marketing automation;
• business intelligence.

In other markets, the search behavior is predominantly in Portuguese.

Only local keyword and search-intent research can identify which terminology the audience actually uses.

GS2’s SEO services include keyword research, technical analysis, content development and strategic planning based on the Brazilian search market.

Regional Search Behavior

Brazil is a continental country, and language, demand and customer behavior vary by region.

The same product may be described differently across states. The fruit known as “bergamota” in parts of southern Brazil, for example, may be called “mexerica” or “tangerina” elsewhere.

Search behavior can also differ between:

• state capitals and smaller cities;
• urban and rural areas;
• regions with different income profiles;
• markets with different levels of digital competition;
• companies with national or regional service coverage.

Mobile access is another important factor.

According to TIC Domicílios 2025, 65% of Brazilian internet users accessed the internet exclusively through a mobile phone.

For some social and demographic groups, the percentage was considerably higher.

This means that mobile usability is not merely a technical recommendation in Brazil. It directly affects whether a large part of the audience can access, understand and use the website.

Slow pages, intrusive elements, small text and forms that are difficult to complete on a phone can cause the user to leave before engaging with the content.

Competition

In highly competitive sectors such as healthcare, education, finance, retail and professional services, Brazilian organic competition can be sophisticated.

Companies may compete against:

• major content portals;
• marketplaces;
• directories;
• established brands;
• specialized publishers;
• competitors that have invested in SEO for several years.

Entering these search results requires more than publishing a high volume of generic articles.

The strategy must identify:

• which topics are strategically relevant;
• where competitors are strong;
• where content gaps exist;
• which pages already have ranking potential;
• which searches are connected to business outcomes;
• when a page should be created or reoptimized.

The objective is not to produce more content than every competitor. It is to build the most useful and authoritative presence for the searches that matter to the business.

Site Authority and Reputation

Search engines evaluate a combination of signals related to a website’s reputation, relevance, technical quality and trustworthiness.

There is no single official Google metric called “domain authority.”

Domain Authority is a third-party metric used by SEO platforms to estimate the relative strength of a domain.

In practice, organic authority is influenced by factors such as:

• relevant backlinks;
• credible brand mentions;
• topical depth;
• editorial consistency;
• recognized authors and specialists;
• reliable sources;
• original research and cases;
• internal linking;
• technical quality;
• a consistent digital presence.

New websites, including websites created by international companies entering Brazil, begin without an established history or reputation in the local search market.

An SEO plan must therefore account for the gradual construction of this authority through content, local relationships, digital PR and links from relevant Brazilian websites.

Educational Content

Brazilian buyers frequently research before making a decision, particularly in markets with higher prices, technical complexity or perceived risk.

Educational content can address this research process through:

• practical guides;
• comparisons;
• definitions;
• frequently asked questions;
• technical explanations;
• case studies;
• implementation criteria;
• advantages and limitations;
• decision-support content.

This content attracts informational searches while helping buyers move toward evaluation and conversion.

Well-structured educational content can also be easier for AI-powered systems to understand and retrieve.

However, no content format can guarantee that a company will be cited by ChatGPT, Gemini, Perplexity or another generative platform.

The objective is to improve the clarity, authority and contextual signals that increase the brand’s potential to be understood and surfaced.

GS2’s SEO Methodology

Many agencies present SEO as a list of tasks: monthly articles, occasional page optimization and ranking reports.

GS2 treats SEO as an acquisition and authority-building system.

The agency’s formal SEO solutions include:

• SEO content;
• SEO audits;
• SEO consulting;
• website migration support.

In practice, these services are organized across seven connected areas.

No single area is capable of sustaining results independently. Together, they create the foundation required to turn organic search into a measurable acquisition channel.

Technical SEO

Technical SEO ensures that search engines can discover, crawl, understand and index the website correctly.

The work may include:

• website speed;
• mobile usability;
• indexation;
• URL architecture;
• internal links;
• structured data;
• canonical tags;
• redirects;
• Core Web Vitals;
• image optimization;
• duplicate-content control;
• crawl errors.

Technical planning is especially important during website migrations.

A poorly managed migration can cause ranking losses, broken links, indexation problems and organic traffic decline.

GS2 includes SEO migration support as part of its technical services to reduce these risks.

Keyword Strategy

Keyword research identifies the terms, questions and problems Brazilian users actually search for.

The process considers:

• search volume;
• commercial relevance;
• search intent;
• competition;
• funnel stage;
• terminology used by the audience;
• geographic variation;
• existing website performance.

A B2B website and an e-commerce operation require different strategies.

A B2B company may prioritize technical searches with lower volume but higher commercial value. An e-commerce company may need to manage broader product categories, transactional terms and large numbers of pages.

Keyword strategy should therefore be based on business value rather than volume alone.

Content Planning

Content planning organizes the topics the company needs to cover across the customer journey.

The editorial roadmap may include:

• pillar pages;
• supporting topic clusters;
• service pages;
• comparison content;
• definitions;
• case studies;
• frequently asked questions;
• bottom-of-funnel content;
• thought-leadership articles.

Topic clusters help demonstrate depth and build stronger relationships between pages.

GS2 applies this methodology both to client projects and to its own marketing, SEO and sales content.

On-Page SEO

On-page SEO aligns the information presented to the reader with the signals search engines need to understand the page.

The work may include:

• title tags;
• meta descriptions;
• heading hierarchy;
• keyword usage;
• search-intent alignment;
• image optimization;
• internal linking;
• scannability;
• entity clarity;
• calls to action.

Each page should have a clear purpose and avoid competing unnecessarily with another page on the same website.

Link Building and Authority Development

Link building helps strengthen the website’s reputation through relevant links from other domains.

The objective should not be to acquire the largest possible number of links.

Quality depends on:

• relevance;
• editorial context;
• credibility of the referring website;
• relationship with the subject;
• natural placement;
• geographic and industry relevance.

For companies entering Brazil, relationships with local publications, associations, partners and industry websites can help establish authority within the local market.

Local SEO

Local SEO improves visibility for searches connected to a city, region or physical service area.

This may include searches such as:

• “near me”;
• service plus city;
• specialist plus region;
• supplier plus state;
• location-specific questions.

The strategy may involve:

• Google Business Profile;
• local landing pages;
• reviews;
• address and contact consistency;
• local content;
• citations on relevant directories;
• geographic structured data.

This is where an agency that understands the Brazilian territory and regional search behavior can provide significant value.

Reporting and Measurement

SEO reporting should go beyond impressions and isolated keyword positions.

GS2 evaluates indicators such as:

• qualified organic traffic;
• conversions;
• leads;
• opportunities;
• sales when attribution is available;
• keyword visibility;
• performance by page;
• non-branded traffic;
• technical health;
• presence in AI-generated answers.

The objective is to connect organic visibility to business results.

At GS2, success is measured by what the strategy contributes to the customer journey, not only by the number of articles delivered.

SEO and AI Search

Search no longer takes place only through a traditional search-results page.

In 2024, Gartner projected that traditional search engine volume could decline by 25% by 2026 as users adopted AI chatbots and virtual agents.

This was a market forecast, not a confirmed measurement of an actual 25% decline. It nevertheless reflected an important shift in how users discover information.

AI adoption is also becoming significant in Brazil.

According to TIC Domicílios 2025, 32% of Brazilian internet users had used generative AI, representing approximately 50 million people aged ten or older.

This is where Generative Engine Optimization becomes relevant.

GEO refers to the practices used to improve how a company, brand or subject is understood and potentially surfaced within AI-generated answers.

GEO does not replace SEO.

It extends many of the same principles into a new discovery environment.

At GS2, both disciplines are treated as parts of the same visibility strategy.

AI Answer Visibility

Companies can monitor whether and how their brands appear in responses generated by platforms such as:

• ChatGPT;
• Gemini;
• Perplexity;
• Copilot;
• Claude;
• Google’s AI-powered search experiences.

This analysis can identify:

• whether the company is mentioned;
• which competitors are more visible;
• which sources are being referenced;
• whether the description of the brand is accurate;
• which topics the brand is associated with;
• where information gaps exist.

AI visibility should complement traditional SEO measurement rather than replace it.

Structured Content

Clear content helps both readers and machines understand the information.

Useful structural elements include:

• descriptive headings;
• direct definitions;
• concise introductory answers;
• lists;
• tables;
• comparisons;
• steps;
• frequently asked questions;
• structured data.

Content that mixes several subjects or relies on vague references may be more difficult to interpret accurately.

Well-organized content provides clearer context and improves the chances that a section can be understood independently.

FAQ Content

Frequently asked questions can be useful when they address genuine audience doubts.

A strong FAQ structure uses:

• the complete question as a heading;
• a direct response at the beginning;
• additional context where necessary;
• clear terminology;
• links to deeper content.

This format can support traditional search features and improve semantic clarity for AI-powered systems.

FAQ content should not be added only to create more keywords. Every answer should provide useful and accurate information.

Authority Signals

Authority and trust signals may include:

• identified authors;
• professional credentials;
• original cases;
• cited research;
• reliable external sources;
• consistent company information;
• clear publication dates;
• expert review;
• transparent limitations.

These elements make the content more credible for readers and provide stronger context for search and AI systems.

Entity-Based Content

Search engines and AI systems use entities to understand relationships between companies, people, products, locations and topics.

A company should clearly explain:

• who it is;
• what it does;
• where it operates;
• which markets it serves;
• which services or products it offers;
• which professionals are associated with it;
• what evidence supports its expertise.

Consistent entity information helps systems associate the brand with the appropriate subjects.

For companies operating in Brazil, the practical objective is to become easier to find and understand across both traditional search and AI-powered discovery.

Companies We Serve

For more than 15 years, GS2 has worked with medium-sized and large companies in Brazil and abroad in sectors where purchase decisions involve research, comparison and trust.

B2B

B2B companies often face long sales cycles, multiple decision-makers, and a strong need for educational content.

Technical SEO, content clusters and sales-oriented pages help these companies generate demand before direct commercial contact.

GS2 explains this process in greater detail in its guide to working with a B2B marketing agency in Brazil.

Healthcare

Healthcare requires high standards of accuracy, responsibility and trust.

Experience, expertise, authoritativeness and trustworthiness, commonly known as E-E-A-T, are concepts emphasized in Google’s Search Quality Rater Guidelines.

These elements are especially important in content that can affect a person’s health, safety or financial well-being.

Education

Education is highly seasonal and competitive.

Organic visibility can influence student acquisition costs by helping schools and education companies remain present throughout the research, comparison and enrollment journey.

Industry

Industrial SEO often involves technical and highly specific searches.

In these markets, a small number of commercially relevant keywords can generate more value than a large volume of generic traffic.

Services

Service companies may depend on local search, reviews, authority and reputation.

SEO helps connect informational searches with service pages, conversion points and customer relationships.
