The structure for successful 30 second radio advertisements divides the time into four parts, which allows for a maximum of 2 to 3 short sentences in each section. In addition to being efficient in the delivery of relevant information, the ad must grab the attention of the listener within the first few seconds and motivate immediate action.
Advertising to Your Audience
Make sure that your advertising reaches your target audience by matching the demographics of the radio station with your product or service. For example, if your product is an energy drink, the audience of potential buyers will be much larger on a station that largely reaches listeners aged 18 to 34 than one with a majority of retirement-age listeners. Ask each radio station to provide the listener demographics applicable to your products -- including age, income and gender -- to find the best match for your advertising campaign.
Start the ad by mentioning the product in a context where it solves a problem. Posing a problem and offering an immediate solution can get the attention of listeners who are trying to find an answer for a pain, inconvenience or aggravation that occurs in their life. For example, juxtaposing the inconvenience of a dead mobile phone battery with a portable charger as the solution will resonate with listeners that experience that problem.
Clearly define how the product will improve the lives of the listeners. Using the portable charger as an example, the benefit for the listeners can be described as never missing an important call again. A benefit that elicits an emotional response can be effective as well. For example, never missing an important call could be modified to never missing a call from a loved one, a child or a grandchild.
Offering an incentive gives listeners a reason to call immediately, rather than waiting. This is an essential element of the advertisement because of the temporal nature of radio spots. An example of an incentive that calls for immediate action would be an offer of 50 percent off of the purchase price for the first 20 callers. Incentives that have a limited time also can be effective.
A Call to Action
Finish the ad by telling listeners what you want them to do next, whether the desired action is a phone call, ordering online or visiting a store. Having a vanity phone number created around the name of the product, or one that repeats the same number can help listeners remember where to call. A simple website address that contains only the product name will be easier to remember as well. For example, if the product in the ad is called Red Widget, having redwidget.com as the address of the website will make it easy to recall if listeners cannot visit the site immediately.
