As previously mentioned, you are your best promoter. The different social media platforms have made it easy to set up your profile, as they want as many users as possible. There are also sites like IFTTT, If This Then That, which allow your post to be applied to multiple platforms, as well as other features. Building a customer base comes from providing great service, but having a social media presence is just something potential customers have come to expect. Like so many other things, schedule a slice of time to add social media content and make it a part of your marketing efforts.
