What is SURROUND?
Surround is a special order type which is characteristic of the display of selected multiple creatives at the same time, during one Page View. For example, if there are three placements in the MASTER/SLAVE structure of a web site: billboard, skyscraper, box, then the surround will display three ad types defined in one Surround. This way, when executing a Page View, any user is surrounded by the ads of a relevant campaign.
