In Analytics, If a single company operates multiple websites that are relatively unrelated to each other and hosted on different domains, it is advisable to organize different properties. It allows for separate data reporting and analyzing the performance of each website in isolation. A company may use properties to differentiate between the mobile and desktop version of their website. This way, the different characteristics of desktop and mobile traffic will be better analyzed. Also property may include an analytic account for mobile app that is created by the company to promote the main website.
