Choosing a social media can be difficult for a band/musician. They must keep in mind that certain platforms have different kinds of audiences. Facebook is about creating a diverse community experience, Twitter is all about quick, short posts in real-time, and Pinterest is about creating themed photo boards. However, no matter what platform you choose (maybe even multiple ones), there are three elements you need to include. These are: brand image, band bio with website link, and common purpose.
People want to see consistency when it comes to an image. If you use a red and black color scheme on Facebook, do the same for all of your social media pages. Also, the banners and background should have a similar look to them. You do not want to confuse your fans with contrasting content. By keeping things similar, you will create a recognizable style with your social media.
Your band bio should also be on your website. The website should also be linked with your social media pages. If your band does not have a website, take some time to work on one. Consult with some help on creating one if you need to, because your website should be your central hub for your online presence.

Finally, you need to know what your purpose is. Are you trying to sell CDs? Are you promoting new material and merch? Are you finding and building a fan base? Whatever your goals are, they need to be implemented across all your social media networking platforms.
