Inventory is the ad space on a publisher's site or app where ads are displayed. In Admixer HB interface inventory is represented by sites, sections and ad units. Each ad unit is the unique placement where the ad can be shown.

The Site is the primary entity that contains one or more sections. A Section is a group of ad units. It has its own JavaScript tag that, together with the corresponding ad unit codes, can be used to initiate the auction for all its ad units simultaneously. Ad unit has the widest range of settings and targeting. Ad unit tag should be placed on the web page if the section tag is absent. More details on the section and ad unit tags can be found here.
