Digital marketing built in Brazil for brands selling here and abroad.
Cg4 Marketing is a Brazilian consultancy helping small and mid-sized brands grow through paid media, SEO and performance — serving clients across Brazil and English-speaking markets (United States, Canada and United Kingdom).
A small, direct consultancy focused on measurable outcomes.
Cg4 Marketing was founded in August 2017 in São Paulo with a simple idea: run digital marketing with the care of someone treating every dollar as their own. We started serving Brazilian brands and, in recent years, began working with clients selling into the United States, Canada and the United Kingdom.
We are not a mall-tier agency. We are a lean team that prefers a small client roster and getting to know each project well — which is why new engagements come through referral and initial screening.
Three things we take seriously.
Data before opinion
Every decision comes from real measurement — GA4, contribution spreadsheets, cohort views. If it cannot be measured, we say so before recommending it.
Remote engagement, done seriously
Scheduled meetings, replies within one business day, deliverables in both languages. Clients in the US or Canada never wait on time zones.
Lean team, no hand-offs
The person who scopes the project is the person running it day to day. No intermediate account managers, no sub-contracted media buying.
What we do.
We focus on performance for brands with mid to premium price points — in Brazil and across English-speaking audiences.
Paid media (Google Ads & Meta Ads)
Structuring and managing acquisition campaigns focused on CAC and LTV — not vanity impressions.
Technical & content SEO
Audit, on-page fixes, content architecture and link building for both PT-BR and EN-US.
E-commerce performance
Integrated acquisition, retention and email marketing strategy for mid-sized online stores.
Expansion into US, Canada & UK
Consulting for Brazilian brands starting to sell abroad: research, message adaptation and first campaigns.
Analytics & measurement
Implementation of GA4, GTM, server-side conversions and Looker Studio dashboards.
Ads & copywriting
Creative assets, scripts and ad copy in Portuguese and English, aligned with brand positioning.
What our clients say.
I hired Cg4 to reorganize paid media for my e-commerce. Within three months the reports became readable and cost per sale dropped consistently. No magic promises, just solid work.
We needed to start selling in the United States and had no idea where to begin. The Cg4 team ran a first simple campaign, measured everything and adjusted with us. It was the real start of our operation abroad.
Working with Cg4 gave us a rare combination: sharp media buying and a team that actually answers emails on time. The reporting is clear and the recommendations are grounded in data.
