Forbes reported on July 22, 2014 that the average PowerPoint slide has 40 words. Truly great presentations won't have 40 words in the first ten slides. When it comes to slides, less is more. Take notice of billboard advertising design: one picture, one phrase. Think of your slides similarly. I encourage clients to use this type of glimpse advertising on their slides in order for the audience to focus on their words and delivery instead of reading the slide.
