Josimar is a family-owned supermarket chain with more than 60 years of history in Greater Buenos Aires. Founded in 1964 in the city of Lanús, the company grew from a small neighborhood grocery store to become a network of modern stores, with more than 300 employees and a value proposition centered on convenience, product variety, and personalized service.
Against the backdrop of rapidly growing e-commerce in Argentina, Josimar recognized the need to take a strategic leap: to leverage its online sales channel as a driver of real growth and improve the operational efficiency of its digital operations. To that end, it chose Known Online as its technology and marketing partner.
The challenge
Josimar had a presence on VTEX, but its digital channel was not being utilized to its full potential. The online store required more rigorous technical management, greater visibility across acquisition channels, and a conversion and customer loyalty strategy that could keep pace with the growth the brand was aiming to achieve.
The challenge was twofold: on the one hand, to consolidate and scale the technical operation on VTEX IO to ensure a smooth, frictionless shopping experience; on the other, to build a 360° digital marketing strategy that would generate qualified traffic, improve the conversion rate, and increase the average customer value over time.
The Solution
Known Online designed and implemented a comprehensive service that encompassed three major, simultaneous areas of focus, with specialized teams working on each one.
VTEX Evolutionary Support
A multidisciplinary team—comprising front-end and back-end developers, solution architects, UX/UI analysts, catalog specialists, and QA specialists—was formed to manage the operation and ongoing development of Josimar’s VTEX IO store. The team’s activities included:
- Optimizing the user experience through heat maps, session recordings, and A/B testing.
- Front-end maintenance and improvement: banners, sliders, pop-ups, landing pages, and mobile optimization.
- Management of key integrations: catalog, payment methods, logistics, OMS, and synchronization with internal systems.
- Implementation of advanced up-selling and cross-selling features to increase the average order value.
- Automation of operational processes on the VTEX backend.
Digital Advertising
The Paid Media team took on the comprehensive management of campaigns on Google Ads and Meta Ads, with a focus on maximizing return on investment for each category and product. The initiatives included:
- A multichannel strategy that distinguishes between brand and non-brand campaigns.
- Search and Display Remarketing to reach users who have previously shown intent to purchase.
- Data-Driven Audience Segmentation and Lookalike Audience Strategies.
- Dashboards in Google Looker Studio and monthly reports with strategic recommendations.
SEO, Marketing Automation, and AI Agent
An organic SEO strategy was implemented, combined with marketing automation and an artificial intelligence layer for product recommendations. Key points included:
- Technical SEO audit, on-page optimization, improvement of Core Web Vitals, and a keyword strategy focused on purchase intent.
- Automated email marketing, WhatsApp, and on-site workflows for abandoned cart recovery, upselling, cross-selling, and post-purchase customer loyalty.
- Development and implementation of an artificial intelligence agent that analyzes orders in real time and generates personalized recommendations for complementary and upgraded products, using continuous learning based on acceptance rates.
Results
The combination of robust technical operations, an efficient traffic acquisition strategy, and a layer of automation and artificial intelligence resulted in concrete and measurable results for Josimar’s business.
- +80% year-over-year growth in online transactions, cementing the digital channel as a strategic sales driver for the company.
The online channel has evolved from a supplementary presence to a central pillar of Josimar’s business strategy, featuring a scalable operation, actionable data, and a shopping experience aligned with the expectations of today’s digital consumers.
Josimar’s case demonstrates that digital transformation in the supermarket industry isn’t just a matter of technology: it’s a business decision that requires strategic vision, coordinated execution, and the right mix of specialized talent. Integrating VTEX technical support, performance management, SEO, automation, and AI agents into a single workflow enabled Josimar to multiply its online results in record time.
Known Online is the partner that Latin American retail chains and supermarkets need to take that leap: with proven expertise in VTEX, multidisciplinary capabilities, and a business model focused on real business results.
