Split your slides

It’s a misconception that you have to limit the number of slides. Doing so forces you to fit multiple stories onto one slide. This is bad for two reasons: First, it creates overcrowded slides. Second, it makes it difficult for your audience to focus, as they are exposed to multiple sub-stories simultaneously.
You won’t save any presenting time and it can actually be less effective. Instead dedicate one full slide to each point. While your slide count will increase, your effectiveness in communicating those ideas will likely increase because your audience will be focused on one single idea rather than juggling three different ideas at a time.
