The archiving feature allows you to archive apps and placements that are either irrelevant, inactive, or no longer needed.
As most publishers prefer to only see active Apps and Placements, this feature gives you control over what shows front and center on the Inventory Index Page.
Archiving Entire Apps or Placements
You have the ability to archive a single placement for an app or site, or you can elect to archive the entire app or site. If you choose the latter option, all placements that were created under the app or site will automatically be archived.
Viewing the Archive
You can access the Archive to view all apps/sites and placements and or move an archived placement back to the Inventory Index Page if you so choose.
