Listen to your audience

Before you start your campaign, find your audience's peak listening time. A coffeehouse would most likely find success if its ads were run during early-morning rush hour. Each community market varies a bit, so the commute might be earlier or later or longer or shorter depending on the location.

I recommend: Check out your metro area's commuter habits — including commute start time, travel time, transportation method used and a comparison with U.S. national averages — at Arbitron. To download a commuter profile, click on "Survey & Data", then click on "Metro, Market and Survey Area Information" and then "Metro Commuter Profiler."

Dial in the right station

The type of radio station is just as important as the time your spots run. If you're trying to appeal to housewives, then a pop station would be better than a sports talk station. Think about your target audience and ask the radio stations in your market for their listener demographics.

I recommend: Look up the current addresses, station names (including call letters), broadcast times, frequencies and formats at Arbitron.com or Radio Locator. For more tips on finding the right station format, check out businesstown.com.

Producing your radio spot

Instead of hiring a graphic designer as you would with print ads, you'll need to start with a producer to come up with a concept. Many radio stations produce ads in-house. But if you're planning a campaign with more than one radio station, you may want to have the freedom that an independent production company can provide.

I recommend: Learn about production fees, how to choose talent, length of radio spots and advertising on more than one station with one consistent message in "How Radio Ads are Produced" at Entrepreneur Magazine.

When you meet with the sales representatives at the radio station you choose, ask about alternatives to 15- or 30-second advertisements. For instance, ask if you can host an on-site remote broadcast, or ask if they'll name you as a morning show sponsor if you purchase a certain number of spots. Even when they read the traffic report, they usually drop the name of one of their advertisers.

I recommend: Check out addme.com for more suggestions on alternative advertising.

Ready, set, advertise

After you've had your ad produced, you can use it any time by purchasing your own radio ad spots. If you want to save money, you can have radio stations bid against each other in an online auction for your business.

I recommend: Bid4Spots.com allows you to post your requirements and radio stations that fit the format and audience that you desire can sell you last minute airplay at deeply discounted rates.
