All of the methods need one thing to be successful and that is repetition
. If you run an ad once and doesn't work, it may have not reached the person at the right time or they even may wait awhile before even calling. Whichever methods you choose, give at least a four month period and send out multiple times. The person looking at your ad may not need your services at that exact time but may later. Repetition is critical to be effective and research shows between 3-7 times points of contact are needed, depending on the industry and media type, before a customer acts on an advertisement. Without ample time to test, it is hard to make a decision on the effectiveness.
