Development of new media and Web 2.0 changed the way we communicate.As a result social media has even been used by business-to-business (B2B) companies as a communication channel, facilitating changes in the purchasing and decision making process. Customers now search for information online, including social media, where they are looking for informative and relevant content to engage with by liking, commenting, sharing or clicking. The biggest social media network is Facebook, but the largest professional social media platform is LinkedIn. The aim of this thesis was to find out, whether LinkedIn is really more successful in engaging the users in B2B than Facebook. With a case study of Danfoss Heating we performed a qualitative analysis of content followed by a quantitative comparison analysis with the support of Power BI which showed that informative content is more engaging. We also found that content published on LinkedIn is far more engaging to users which makes LinkedIn the better social media to be used in B2B for user engagement, as it generates more likes, shares and clicks than Facebook. With this, companies can easily share relevant information among their followers.
