So, I've had a site up for almost three months, but have only used text and image content ads. I'm skeptical that anyone would ever use the search ad and when people say link ads I guess they mean feeds. Again, I'm skeptical and not sure where I would even place on of those. Here is the link to my site. http://www.iphone4idiots.com/ You can see I'm using an image only add in left and right sidebars and then depending on page I'm using on other in the middle. So, would anyone suggest adding a link ad add somewhere on the site and if so where??? Thanks again, I just confused why some days I've made $0.30 and others I've made $6???
