I can’t believe I have never heard of these guys before. How can you go wrong with $20 banners? I guess this isn’t really a Search piece. However anything that’s going to drive more traffic can only be helpful from an SEO point of view. Also we have been having lots of success with certain verticals on Google’s content network this year – especially using banners. So we will start recommending this to clients that don’t have the agency resource to develop banners for them. Banners on the Google content network are great because while driving awareness they are bought on a cost per click basis so they can still be optimised for click through rate and ultimately conversions.
