One or two seconds sounds pretty long to me. I think I close accidental ad clicks well under a second a lot of the time as I realize what I did without waiting for the site to load.
Yeah I do that too but I don't want to pay for those clicks either. I want genuine interested clicks. Google is set up to get me to pay for clicks, not to give me the right clicks.
Or at least it was when I used them. It's been a while because of that.
