Yellow pages are a service directory for customers who don't have a preferred provider in the category of service they're seeking. If your business is retail, put your money somewhere other than the yellow pages. Few, if any, customers consult the Yellow Pages when looking for clothes, food, furniture, etc. But as a service provider you may want to consider it. They key to a Yellow Page ad, like any other ad, is what you SAY in it. Speak directly to the felt need of the customer. Talk like they do. Use their words, not your own industry jargon. Active verbs are essential to response. "See samples." "Take a look" "Waiting for your call." "Delivered on time and under budget." Good luck to you.
