All presentations should include the beginning, the middle, and the end. The first part of your presentation should always present the problem. The middle of the presentation should present your key findings. By the end of the presentation, your audience should have a better understanding of the solution. Less is more. There's a tendency to make a presentation slide excessively complicated with flashy images, strange transitions, and too much text. These features are often unnecessary, and tend to make the viewers get bored. Instead, keep each slide short and plain, using one image to sell your idea. Using bullets   is a bit of a cliche  , but if you must use them, never exceed   more than one line of text per bullet. Branding is the key. Whether you're stating a new business idea to investors or describing a new product to customers, you'll want your presentation to reinforce your brand's image. Use the same color1 schemes, fonts  , and logos that you use on your website or company literature. There's an assumption of what a Power Point is supposed to look like, and company standards falls through the floor. Give them a break. According to a recent research, the average adult attention span for a presentation is just 20 minutes. It's always best to keep your presentation short and to the point, but if you must exceed the recommended 20 minutes, try giving your audience a moment to relax. "You can extend attention spans by giving your audience a rest," the study says. This can be done by telling a story, giving a demo, or doing something else that gives the brain a break. Practice it again and again. In the end, a great presentation will come down to the speaker's ability to capture the audience's imagination and keep their attention. The presentation and the speaker should work together and they can be complementary   to each other. The best presenters won't have to look down at the notes and will never be reading from a script. A good speaker can focus on the key points and convey information well. How can you make a presentation slide not too complicated?
By keeping each slide short and plain. By using flashy images and much text. By using more than one line of text per bullet. By using more than one image to show your idea.
