Yieldex tools help publishers get more revenue from their premium inventory. Yieldex helps publishers get more revenue from their premium inventory, with three key tools: Proposal Analysis, Delivery Planning, and Proposal Analysis. Inventory management has been a challenge for online publishers since ad serving began in 1995, but excess inventory has largely hidden the problem. Now, however, publishers' growing use of advanced targeting (i.e. behavioral, demographic, etc.), particularly across a network of sites, is making the ad sales process increasingly complex and unwieldy, resulting in lower revenue efficiency. Ad operations teams are struggling with inadequate tools to accurately forecast inventory and predict how ads will deliver, leaving premium inventory wasted on remnant networks. CFOs and sales chiefs are clamoring for better visibility into future revenue, inventory use, and lost opportunities.
