One top-notch way to give the BEST PowerPoint presentation is learning from the master, Steve Jobs…
In one word : SIMPLICITY
Very few words.
Simple facts.
Big graphics with minimal text.
Smaller letters to clarify the data.
The speaker gives the details, not the graphic.
Few colors.
One more thing: If you provide too much information on your presentation people will get distracted trying to read or understand your content. They will lose interest in you and whatever you’re saying.
As a speaker you should try to be the focus of your audience. The mission of your power point should be to support your statements NOT steal the center of attention.
