Convincing the doubters

From analysing the traffic on our websites, it's pretty clear to me that many of our visitors go to the subscription page of Value Research Stock Advisor but never take the plunge. Some go only once, and some go a few times. A handful go many, many times. Why don't they try it out? My team and I have thought about this a lot. More than thinking about it, we've interacted with many of our doubters, figured out their problems, and, I believe, fixed them.
