At one time, publishers would be impressed with your sheer number of Twitter followers (or Facebook likes), but now their focus is more on engagement. What is your Twitter strategy to build your author platform?
Are you interacting with your Twitter followers? Do you try to connect with them, and do they appreciate the value of your tweets?
Follow people who share your mindset and fit this perspective, and don’t worry about following back the folks who don’t.
Don’t focus on your numbers of social media connections but on the quality of interaction with the connections you have. This is the ideal Twitter strategy.
