Social Media - What's Your Purpose?
Robert WallisIf you're engaging on social media for fun that's fine and purpose enough.
If you're not there for fun, you are engaging on behalf of a business where your purpose should be ultimately to impact a business objective. To have a business outcome.

Strategy
Strategy is made up of strategic components and actions designed to achieve your business objective.
Keep your business objective front of mind. Evaluate every action you take against your business objective for being there. Everything you do should align with that.
Do not focus on gaining followers. That is not a business objective.
