Hi, I'm building a new site (white hat). I want to run this for a long time and I'm also after a very good design. I have reduced this to having 1 ad in my sidebar about 225x225 pixels. So, all attention will be now focused on this 1 ad so I want to try and make the most money from it as possible. I will be running adsense at the top of my blog as well as text affilate links throughout my site. But I was wondering the best way of using this one ad, affilate links? Or setup some kind of targeted ad that is based around categories of the page?
