How Forecasting Works
Forecasting in TAP involves a dynamic set of processes with many variables. It uses algorithms based in part on estimates, such as the estimated number of breaks in the forecasting period and the depth of those breaks. It is normal to see small fluctuations in reported avails, even when you run the same query twice.
After creating or modifying flights, wait one minute before running a forecasting report
Triton caches responses to your forecasting queries for one minute. In cases where you submit the exact same query in less than a minute, Triton returns the same result. Triton will consider new and modified flights when the cache expires.
Forecasting for Impressions and Spots
The Inventory Availability reports for TAP Impressions and TAP Spots show forecasted inventory for your flights, as well as contending flights that could be affected if the flight is booked.
The forecasting algorithm looks at the past 28 days of activity across your network, or across specific stations/podcasts. It looks at all impressions delivered, regular, filler and programmatic, as well as missed opportunities.
For the contending flights, Triton looks at everything booked within the specified date range and estimates the contending impressions for each flight considering all their targeting parameters. Triton then deducts the sum of the contending impressions by the total to get what is estimated to be available for your query.
Forecasting for Reach Extension
A reseller can see the inventory that a Triton inventory owner has made available through Reach Extension with the TAP Reach Extension report in Inventory Availability.
This report provides an accurate and relevant forecast for resellers by calculating the intersection of the following:
Reseller targeting that you specify in Inventory Availability > TAP Reach Extension
Inventory owner’s flight targeting and priority rules
