Don’t use so much information on the slide because you don’t want your audience to be reading the whole time while you are talking.
Make the slides Limited, when to many things are going on the audience will have a hard time staying on top of things
Don’t use transitions because it doesn’t make your presentation look professional.
Use High Quality Pictures because you want to entertain your audience as well as give them good infornmation.
Make sure to use complementary colors so that your slides look good and professional. You don’t want to irritate your audience with confusing colors.
Make sure you pick good fonts, because some may be harder to read than others. And you of course want your viewers to be able to read your writing accurately.
Use Videos and Audios because sometimes its easier to have people listen and watch a demonstration. However don’t make the video to long, or you might bore the viewers.
Make sure you take your time when creating this presentation. No one likes to see a presentation that was done last minute.
