Jumping right into the next square offering from Google Adsense, we have the 200×200 – Small Square. If you’re sidebar or content area is to small to accommodate the 250×250 – Square or the 300×250 – Medium Rectangle, your next option is the 200 x 200 – Small Square. The 200 x 200 – Square is multifaceted and can be placed in many areas of your page. Additionally, with some testing as to placement and design, this ad unit can produce a respectable amount of clicks. However, just like the 250×250 Ad Unit, the 200 x 200 has been relegated to the disapproved list by Microsoft Advertising, as well as the IAB (Interactive Advertising Bureau), in favor of the 300×250 rectangle.
