ad unit -> διαφημιστική μονάδα
The ad unit is vessel that carries a brand’s message through publications, broadcasts or applications. Or, more simply, it is the ad itself.
This term can also be used to refer to the type of ad unit, such as a bilboard, TV commercial or interactive skin.
Some online publishers only sell advertising based on guidelines set by the International Advertising Bureau (IAB), to attract a broad spectrum of advertisers. More exclusive ad services and publishers, especially those in the social media realm, like Blogads.com and Facebook, have proprietary ad units that are not based on IAB standard, for which advertisers can create uniquely engaging ads.
