When you get traffic and no clicks, I look for two things: 1) How good does the parking page look. You know, colors and images. Your page looks good and has a photo of a woman with an apple. This image may or may not be the best for your page.
And 2) what are the ads that are showing? If the ads seem to be good, but no one is clicking, then the ads may not be what they are looking for.
In your case, you have ads about "patients" (Patient has two meanings in English, a person that is ill or recovering and the other is to be calm while waiting for something).
You could try other types of medical and health keywords, but I would try, love, dating, and p0rn keywords which I suspect is what your visitors hunger for...!
