It’s not surprising Powerpoint presentations have become the norm for visuals in most business meetings. They're quick to produce, easy to update, especially when using a cloud-based solution, and effective to inject visual interest into the presentation.

However, they can also spell disaster even for experienced presenters if you make any of these crucial Powerpoint mistakes. The key to success is to make certain your slideshow is a visual aid and not a visual distraction.

For the best results, avoid these common “seven deadly sins” of Powerpoint presentations.

1. Slide Transitions And Sound Effects.

They become the focus of attention, which in turn distracts the audience. Worse yet, when a presentation containing several effects and transitions runs on a computer much slower than the one it was created on, the result is a sluggish, almost comical playback. Such gimmicks rarely enhance the message you’re trying to communicate. Unless you are presenting at a science fiction convention, leave out the laser-guided text!

Leave the fade-ins, fade-outs, wipes, blinds, dissolves, checkerboards, cuts, covers and splits to Hollywood filmmakers. Even “builds” (lines of text appearing each time you click the mouse) can be distracting. Focus on your message, not the technology.

2. Standard Clipart.

Death to screen beans! Powerpoint is now so widely used the clipart included with it has become a “visual cliché.” It shows a lack of creativity and a tired adherence to a standard form.

First, make certain that you need graphics to enhance your message. If you do, use your own scanned photographs or better-quality graphics from companies such as .

Screen captures can add realism when presenting information about a Website or computer program. Two popular screen capture programs are Snagit () for Windows and Snapz Pro () for Macintosh.

Both are available as shareware.

3. Presentation Templates.

Another visual cliché. Templates force you to fit your original ideas into someone else’s pre-packaged mold. The templates often contain distracting backgrounds and poor color combinations. Pick up a good book on Web graphics and apply the same principles to your slides. Create your own distinctive look or use your company logo in a corner of the screen.

4. Text-Heavy Slides.

Projected slides are a good medium for depicting an idea graphically or providing an overview. They are a poor medium for detail and reading. Avoid paragraphs, quotations and even complete sentences.

Limit your slides to five lines of text and use words and phrases to make your points. The audience will be able to digest and retain key points more easily. Don’t use your slides as speaker’s notes or to simply project an outline of your presentation.

5. The “Me” Paradigm.

Presenters often scan a table or graphic directly from their existing print corporate material and include it in their slide show presentations. The results are almost always sub-optimal. Print visuals are usually meant to be seen from 8-12 inches rather than viewed from several feet. Typically, they are too small, too detailed and too textual for an effective visual presentation.

The same is true for font size; 12 point font is adequate when the text is in front of you. In a slideshow, aim for a minimum of 40 point font. Remember the audience and move the circle from “me” to “we.” Make certain all elements of any particular slide are large enough to be easily seen. Size really does matter.

6. Reading.

An oral presentation should focus on interactive speaking and listening, not reading by the speaker or the audience. The demands of spoken and written language differ significantly. Spoken language is shorter, less formal and more direct. Reading text ruins a presentation. A related point has to do with handouts for the audience.

One of your goals as a presenter is to capture and hold the audience’s attention. If you distribute materials before your presentation, your audience will be reading the handouts rather than listening to you. Often, parts of an effective presentation depend on creating suspense to engage the audience.

If the audience can read everything you’re going to say, that element is lost.

7. Faith in Technology.

You never know when an equipment malfunction or incompatible interfaces will force you to give your presentation on another computer. Be prepared by having a back-up of your presentation on a CD-ROM.

Better yet is a compact-flash memory card with an adapter for the PCMCIA slot in your notebook. With it, you can still make last-minute changes. It’s also a good idea to prepare a few color transparencies of your key slides.

In the worst-case scenario, none of the technology works and you have no visuals to present. You should still be able to give an excellent presentation if you focus on the message. Always familiarize yourself with the presentation, practice it and be ready to engage the audience regardless of the technology that is available. It’s almost a lost art.
