According to a new survey taken in March, almost all (95.8%) of social media marketers worldwide believe that Facebook produces the best ROI out of the major social platforms. With Facebook continually adding new revenue streams, it is not a suprise marketers are using Facebook for their marketing efforts.
Instagram on the other hand seems to have almost every industry fully using the platform. Maybe they have not discovered yet that Snapchat allows you to create unique content in-app that may increase brand following? Interestingly enough though, posting frequency is higher on Snapchat than Instagram on a weekly basis.
