Agence digitale K4

Agence digitale K4 operates from Strasbourg, with a second office in Douai/Lille, working across the Grand Est and Hauts-de-France regions since 2014. The team, made up of a small group of digital marketing specialists, serves e-commerce sites, showcase websites, industrial companies and BtoB and BtoC service businesses that need qualified, lasting organic traffic and tailored digital experiences. The agency's core offering is SEO, covering local, national and multilingual referencing across search engines including Google, Yahoo, Bing and Baidu, with the team continuously training on algorithm updates and translating them into client work. Alongside SEO, it handles paid traffic acquisition through Google Ads, Meta platforms (Facebook, Instagram, Messenger), other social networks, LeBonCoin and native ads placements, with certified staff on the relevant advertising tools. Social media work covers content planning, production, publishing, moderation and reporting, adapted to each platform's format and tone requirements. Website and application development is carried out under a dedicated studio unit called La Fabrikk, created in 2018, which focuses on UX/UI design and builds sites intended to be SEO-optimized, manageable by clients and scalable over time. The agency also lists CRM consulting, content marketing, email marketing, sales outsourcing and analytics among its areas of activity, and presents case studies covering e-commerce, SEO, social media and local presence projects.
