What I wonder about those 300x250 ad blocks though is if your visitors have to scroll down with their finger on an iPhone, don't you generate a lot of accidental clicks?
Good question, I've no answer to that. I have those ad size blocks on my pages plus I have in-text Vibrant media ads. When i view the pages on my mobile I can avoid the accidental clicks but that may well be because I know what's an ad and what is not.
When I view my pages on a PC I almost always end up showing one of the in-text ads cos my mouse is going past them across the page.
But my earnings in Adsense at the end of the month seem to be about 98% of the click value so as far as I can see Google aren't detecting invalid clicks. And mobiles are now 30% plus of my page views.
I would really appreciate any opinions on this.
