Advertising tips : When designing a print ad, don’t forget the main purpose of the ad—to sell! You have to give the reader a clear path to take. This can be as simple as remembering to place a phone number in a prominent place in the ad. Or it can be more detailed and can include such elements as coupons, special offers, or a web address. This should be both the starting and ending point of your print ad design. Know before you start what your objective is, and end by critically examining your ad to make sure that it meets that goal.
