As the Pontiac bidder receives millions of bid requests each day, we collect a random sample and store the log level data for these requests to provide insight into all available inventory for forecasting & targeting purposes. Pontiac users can export csv files that contain all of the unique combinations across the inventory parameters available for targeting. This tool can be used to create informed targeting or block lists on your CTV campaigns. See Challenges in the CTV Landscape & Inventory Discovery Tool for more information.
