I remember on an old Altervista site, I'd be able to get a balance change after a hundred views.
I've made many more now on lettingthedaysgoby.altervista.org but somehow the ad revenue chart and counter haven't moved at all. I don't think that's very fair.
My style.css could trip up Altervista somehow cause it puts the ad in a div with the right size so the layout doesn't change when the ad loads. Here is one such layout which seems to mess it up.
