I am wondering where I should place adverts for my site. I understand a bit about human computer interaction. So I am assuming that the adverts need to be positioned in places where they will catch the users attention to be clicked. I also know that adverts can be very irritating. I am wondering what the best position is to place adverts.
I know some sites place their adverts in the side bars and some place adverts at the end of each article. What is the best of both worlds which takes into account the best way to get the users' attention about the advert without being irritating to them? Right now I have placed my adverts on the edge of my page.
