I looked up another keyword phrase top rated diet pills and what I found interesting about this term was that it was not searched for as much yet the ppc was about $2.46 on average. I need to do some research and find out why this is so. I am guessing that maybe more companies what to use this term, but like I said I am not completely sure. I would really have to do more research to see if I can get the reason why. I was asked why so many companies advertise this way where as they pay every time someone clicks on their link, and to be honest the best answer would be they are getting a lot of business this way. Now this is not for everyone though, as I have heard a lot of companies lose money this way. I suggest if you are thinking about doing this with your business or blog that you do a ton a research to see if it even worth it.
