Do be familiar with analytics.
As much as people say music and math go together, I’ve rarely found musicians interested in singing about the quadratic equation. Despite that, if you’re trying to build a following on social media then analytics is vital. Most of the information out there is free (e.g. Facebook Insights, Twitter Analytics, Google Analytics, Iconosquare, Klout, etc.) and you don’t need a degree in statistics to understand it.
If you’re consistently updating your Facebook, Twitter, Instagram, or Tumblr then you need to understand basic information like impressions, engagement, click through rate, and a host of other things if you ever want to improve. Defining your social media goals by how many followers you have is an act in futility. Social media is more than just how many people follow you in a week. If you’re posting 10 pictures or tweets and are struggling to get a like or favorite, then you’re doing something wrong. Analytics is the key to understanding how to bridge that gap.
