As someone who's banner blind I can honestly say that I have no idea. Having said that, if the adverts are unobtrusive and relevant to what I'm looking to buy

As someone who's banner blind I can honestly say that I have no idea. Having said that, if the adverts are unobtrusive and relevant to what I'm looking to buy (e.g. I'm looking at a camera review because I want to buy a camera and an advert offering me 10% off digital cameras appears inline without interrupting my experience of the review) then I'll click. The answer to online advertising isn't to hit more people, it's to hit the right people in the right way.
