Make sure that your slides are not overloaded with information.
Make sure they are readable – font size and right colour.
Make them simple.
Reduce the amount of text on your slides.
Use images – PowerPoint is a visual medium.
Don’t overuse bullet points slides.
Use animation and sound effects very selectively.
Go for more white space.
Create interesting titles for your slides.
Consider when and if to hand out print-outs of your slides.
Remember in slideshow view you can use the B key to get a black screen
and press it again to bring the slide back. The same thing works with the W key
to get a white screen.

If an audience have not completely understood what the slide is trying to tell them within 20 seconds the slide may need changing!
