GSP consists of two elements: the teaser ad and the expanded ad. The teaser ad shows a preview of the expanded ad and encourages users to click and open the message. The teaser ad also displays the brand logo in a specified format (144 x 144 pixels). Then, the graphic expanded ad, which covers the entire page, opens. The client usually pays only for the number of clicks on the message.
