A premium inventory is high-quality ad space offered by trusted publishers, ensuring better visibility, targeted audiences, and superior performance metrics. Most often, a publisher’s most sought-after inventory includes placements on the homepage and other frequently visited pages.
Advertisers, however, often view premium inventory as placements viewed by their target audience. This type of inventory is of higher value to advertisers, meaning it often carries a higher CPM.
Additionally, premium inventory is often sold via direct and private marketplace deals but can also be sold via RTB auctions.
