Your slide should have plenty of white or negative space. Don’t feel like you need to fill empty areas on the slide with logos or other unnecessary graphics or text boxes that don’t help give better understanding. The less words and clutter on the slide, the more powerful the visual message is.
The best slides have no text on them, making it virtually meaningless without narration of the speaker. Lots of text and bullet points is boring to the audience.
Limit slide transitions and keep it professional. Lots of transition can get tedious and slow, making the audience bored.
