The 3 variables of success on social media

1. Consistency
   1. Are you showing up as yourself? Do you come back again and again for your audience? 
2. Frequency
   1. Are you posting content multiple times per day to reach your community? Are your posts actually reaching the people you want?
3. Quality
   1. Is the content valuable to your audience? Are they intrigued by what you share?

If you consistently show up with a message worth sharing, and you deliver it enough times to the people who want to hear it so that they do something, I would consider that a success on social media.
