It just depends like everything else, what you are advertising, who you are targeting, what kind of page, etc.
I've joined a lot of programs and made purchases too, from viewing the ads in CS.
Some people don't like ads but I actually appreciate them. It keeps me in the know. It keeps me knowing
what is out there and what is going on. I've come across some very good information, etc, by viewing the
ads.
But no one has a crystal ball and therefore cannot tell you what your results will be.
