Design the slide design of your PowerPoint presentation like a good poster or ad.
The ideal slide has a strong headline and a picture that matches the headline and creates an arc of tension between the headline and the image. Illustrations and diagrams are also ideal for this purpose. Photos should arouse emotions and must therefore be carefully selected.
The following therefore applies to the most important slides in your presentation: Use only one good, full-size motif per slide. Take all the bullet points you have planned for and reduce them to a single core message. With a perfect image (a picture is worth a 1000 words), you don’t need any text other than the headline. The Bulletpoints banish you into your Speakernotes and into the Handout. The same fate will befall all footnotes, page numbers, sources and dates.
If there are still elements on the slide master of your PowerPoint presentation that have nothing to do with the message of your PowerPoint slide, logos can be such a case. Delete them … done.
Repeat these steps on each slide of your PowerPoint presentation.
