Ideally, I would like to see in the screenshots, descriptions and figures. For example, display and screenshots of how it looks, and the numbers are the average, how much it is at all relevant, the ratio quality/price. In General some allowance for choice of advertising format. Media, contextual, display, teaser, media-contextual banner, text and graphic blocks, Yandex advertising network, banner, etc.
whatever dress you are wearing, you are still fucked...
