C3dweb Agência Marketing Digital

Based in São Paulo, this agency has operated in digital performance marketing since 2006 with a small team of up to ten people. Its client base spans sectors such as B2B industrial companies, hospitality, tourism and health and wellness businesses, working with brands that need ongoing acquisition and retention rather than one-off campaigns. The stated focus is on connecting marketing activity to business outcomes—sales, repeat purchases and measurable return—rather than on isolated metrics like clicks or social engagement. Services cover paid traffic management on Google, Meta and LinkedIn aimed at qualified lead generation, alongside SEO and AI-driven search optimization (including visibility within generative search tools). Work also includes website and landing page development intended to convert visits into sales, conversion rate optimization, and email and social media marketing. The agency structures engagements around what it calls the "Método C3," a five-stage cycle covering diagnosis and immersion, strategy alignment between marketing and sales, acquisition through paid media, SEO and content, conversion and CRM-based relationship management, and ongoing analysis of metrics such as CAC, ROI and LTV. Artificial intelligence is applied internally to speed up analysis, content production, generative SEO and business intelligence reporting, while strategic decisions remain guided by the team. Additional services include CRM implementation, sales funnel analysis, brand positioning and identity work, and BI dashboards for data-based decision-making.
