Thanks for your comment, Andrea. I'm glad the post was valuable to you. I'm going to share some recommendations in the follow up piece. Cluster posting, in my view, is a definite worst practice, regardless of the motivation. I'm also not a huge fan of overposting the same content in a short timeframe. And as a follower, A/B testing on Twitter feels like bait and swtich!
Attending to feedback is critical to knowing what is/isn't working and adapting accordingly. And there are definitely no simple formulas for engagement - just a set of best practices that keep evolving!!!
