I think Social Media is the go to to promote everyone's business. I still don't get why most stores and business companies in my area don't have a facebook page or even an instagram, which is what most people around here use. It's so simple to create and mantain... They could totally hire me for that - for free - because it's so simple to mantain social media nowadays and it's something I really enjoy and put my heart into.
It really depends on what the business is about, but the secret is to be kind to your clients. Always make sure to answer their questions, along with a smiley face. Even if you don't like that person. Always try to be kind and patiente. The bad part of the internet is not knowing how people on the other end of a computer is feeling, and by not adding a smiley face, the other person might think you're mad at them, so that is something I always do.
- see? It always makes things more confortable.
Another thing I do is make images with a quote, or something as simple as a "good morning" in the morning, just to show people we are there and are interested and are saying hi to our clients. That would also make them want to share or retweet the image. And there's a lot more you can do.
The best thing of social media for me is that it's easy to use and you can do it from anywhere you are, you just need an internet connection.
If anyone needs any social media help with their business, feel free to PM me and I'll try to do my best!
