You don't have to have a profile on every social media platform in order to be successful. In fact, you'll probably get burnt out and overwhelmed if you do.
If you're just starting out, go small and pick 1-2 platforms that make sense for your business.
There's no sense having a profile on a platform your customers don't use, and there are other social platforms that cater to specific types of interests and businesses. Know where your customers are, then build your presence there.http://ijenti.com/choose-social-media-platforms-3-questions-ask/
