When writing ad copy, focus on a single unique selling point or number-one user benefit. Something that makes you different from your competition. Relate that to the rest of the copy you want to feature. Eliminate dead weight or overused statements from your copy, such as: For all your . . . . needs. Quality . . . . supplies. All work done by skilled professionals. Professionally designed and supervised. The perfect gift for any occasion. Modernize to economize. You've got to see it to believe it.
