I know that many of us struggle with creating and maintaining good advertising on our sites to keep them up and running. Many of us creating them have very little return on investment and most of the time it is because of very poor tracking and anaylsis. I have done some research and located AdSymetrix This company is very skilled in tracking information. With their tools tagged to your ad you will get the critical info of phone calls, clicks and emails generated by your ad. This type of info allows us to create better targeting all the while our competition will have no idea what is happening behind the seens of the ad. AdSymetrix Signup has very reasonable prices while sign up and click and email tracking are free. I read several testimonials on their site to show that regular businesses had no idea who was reponding to their ads, now they know and perhaps more important they learn what does not work. Give them a try.
