Make the topic meaningful, but do not use too broad a scope of content.Focus on three or four points to present.Delve into each of these points in an order that leads from one to the next.Make your information clear and logical.

Deliver what your audience came to learn. Stick to important information only. If they want to know more, they will ask—and be prepared for those questions. 

Choose appropriate colors for the design of your slide show.Keep text to a minimum. Aim for one point per slide. The only exception is when your slides will be presented as a handout, as often happens at professional conferences.Make sure the text is large enough to be read at the back of the room, and there is adequate contrast between the background color of the slide and the text content.Stick to plain and simple fonts that are easily read. Nothing is worse than some fancy, curley-que text that no one can read. Keep those fonts for greeting cards.Aim for elegant simplicity. No need to add unnecessary clipart, for example.Whenever possible, use a picture to illustrate your point. Don’t use them just to decorate the slide, nor should they be so busy that they detract from your point.

Will it be inside or outside?Is it a large hall or a small boardroom?Will it be a dark room or a room with an abundance of natural light?Will the sound echo off bare floors or be absorbed into carpeting?Do you have a sound system?Do you know how to access tech support?

In the case that you are the presenter but did not create the presentation, check with the writer to know which points need special emphasis.Allow time for questions.Practice the entire presentation, out loud, on your own webcam. Study your delivery and timing and make notes about what to include or omit on any given slide.
