1. Lose the clip art. Use a nice-looking photograph instead. Preferably a photo that shows your product in use or a satisfied client, but even a well-chosen stock photo would be better than clip art. And animated clip art? Unless you're a real design whiz, just say "never".
2. Reduce the size of large photos. If it's over 400 pixels wide, it's probably too big for your business web site. Hint: use your image editing program to reduce the size, not your HTML editing program.
3. Unless you really know what you're doing, remove any patterned web page backgrounds. Choose a nice solid color instead.
4. Everyone, including the design pros, should remove these special effects (unless they're part of a Flash piece):
text or graphics that slide into position
blinking text or graphics
spinning text or graphics
page transition effects
sound effects
5. Keep extra large type to a minimum.
6. Remove underlining from any text that is not a link.
7. Use bold, italics, exclamation points, and ALL CAPS very sparingly.
