Social media must be seen as a serious platform for your business, simply because that is the way things are. News, reports, researching products and services, as well as writing and sharing reviews: nowadays all these things take place on social media.
It is good to have an overview of the days and times of day when new posts are read by many people. Your posts and contributions should contain professional images and you should not share information that has not been verified.
You also have to understand what demographic traits your target groups have. To succeed on social media, you need to conduct some research and monitor your efforts. One thing you would not want is to become active on a social media platform that is hardly ever used by your target group.
