A successful advertisement gets a consumer to buy a product or service. This product or service can be a necessity, such as auto insurance, or an indulgence, like the new triple cheeseburger at the local fast food restaurant.
Either way, the ad must motivate and ultimately lead to action by the consumer. To write a radio ad that achieves this, you need to ensure that you overcome the lack of visual elements and capture your audience's attention with words and sound.
