We desire the feelings that we think money will bring us, whether they be happy, secure, or powerful. If your reader does not take action, then you are dead in the water. Believe it or not this is the simplest step. Simply use a directive. The qualified ad is specific and includes more detail about the product you are selling.
Some products lend themselves to qualified ad content better than others.
Hair pieces for men is an example. Qualified ads will receive the least response but more of the responses which are received will result in sales. The partially qualified ad offers a special benefit, such as money or self- improvement. The readers have some idea of what you are offering, but don't know the specifics. If they are interested and desire your product they will follow your directive and send for more info.
