I am working on a long term project that is the evolution of many different projects. I was needing some suggestions on ad placement and ad colors for the following site. www.shareyourexpertise.com Thanks!
I suggest an ad block within the text. Either that or a banner. As for colour, if you put the ad in the middle, where everything is white, make the ad border and background white. For that ad up at the banner location, I suggest a green border/background that matches the banner colour.
