How to pick a good Instagram caption

Here's how to pick the best Instagram caption for your post:

  1. Consider the setting. A great caption is going to cause a visceral reaction to your viewer. This is a type of emotional response. Typically, it will be a positive response. For example, a shiver is a visceral response.
  2. Choose something that matches you. When picking a caption, make sure that you're choosing a caption that matches your overall profile theme. Having a consistent message or tone to your posts will help to grow your following.
  3. Keep it short. A short and sweet caption is going to have a longer impact than a long story. Extremely long captions for Instagram are only great for those who want to tell a deep story and increase their engagement. Generally, the shorter the caption, the better. For example, a short quote is going to perform better than a 500-word caption.
