The most commonly used social media platforms are Facebook, Instagram, Twitter, YouTube and LinkedIn. (There are over 60 different platforms available on the web). Depending on your business and your target market, you may not need to use all platforms. For example, an Occupational Therapist would be better suited to Facebook, Twitter and LinkedIn – all platforms provide more an information providing platform versus Instagram which is more visual.
I use Facebook, Instagram and Twitter for my socials. The content that I post is synchronised across all platforms so that I am not having to triple-handle each post.
