Follow these steps for a successful DRTV advertising campaign
1) Write a script to capture their attention.
2) Research your products target market. Get to know your customer and how they will use your product to benefit their lives.
3) Create an understandable and clear demonstration. You need to be thorough in how your product works and how simple it is for the end user.
4) Testing your commercial: Once the production is done, use a focus group of people to critique and (hopefully) compliment the things you have done correctly and what you have missed the mark on.
5) Cast characters in your infomercial who are relevant and relate-able. If the audience does not understand the character, they can not picture themselves using it.
