Hi Christian, it is critical to track how many visitors or social shares you achieved through your campaigns. This would lead to measuring how many new customers were delivered, how much revenue did they generate and what is the return on the marketing investment. The top three matrices that digital marketers should measure are reach (how many potential audience your campaigns are reaching), engagement (how much time they are speding in consuming and sharing the content) and conversation (if they are turning into quantifiable sales leads). Hope this makes sense.
