I never actually click on ads because I don't even notice them. I've never been the sort of person to pay any attention at all to advertising (I'm sure there are people who will say that we all pay attention to it subliminally - well, I can't possibly know if that's true in my case, since it would happen subliminally!), so it doesn't wash with me. I'm just here to read and write. My eye just seems to miss out the ad sections of hubs.
I can't imagine how so many hubbers seem to be able to make any amount of money. I've been here for four months and I've only made 82p!
