Most of the people that are bitching about conversions just don't know how to make something convert, they think they can get a terra.es account put up a banner buy some traffic for 30$ and make bank. And when that doesn't work, they come here and start bitching about it, they never think they did something wrong.
The people that own succesful programs, tgps or whatever don't bitch because they are succesful for a reason.
