Overview QPS, or queries per second, can be adjusted for Buyer Cloud customers with custom bidders.  Buyer Cloud deploys a custom bidder for each client with a custom Buyer Cloud setup, and pre-filters traffic to each individual bidder instance. This traffic pre-filtering is controlled by an appointed customer success manager. The management of traffic is critical to ensuring campaigns scale and deliver successfully. QPS Understanding QPS (Queries Per Second) QPS ,  or Queries Per Second, refers to the number of auction requests filtered and sent to a custom bidder. Buyer Cloud charges a flat monthly fee based on the selected QPS tier. Buyer Cloud uses automated maximum request limits to keep the number of requests within the bidder's contractual QPS tier, if applicable. As a result, bidder traffic is controlled and predictable, and QPS-associated costs are consistent. Converting QPS to Impressions To estimate the number of daily eligible auctions, multiply the QPS value by 86,400 (the number of seconds in a day). For example, a 10,000 QPS tier equates to approximately 864 million auctions per day. The actual number of impressions won depends on bidding strategy, bid pricing, and demand. For instance, with a high CPM strategy and an estimated 10% win rate, 864 million auctions could result in approximately 86.4 million impressions. Source of QPS Buyer Cloud integrates with dozens of ad exchanges and accesses high volumes of QPS through four AWS data centers: US-EAST-1 US-WEST-2  (used primarily for western North America traffic) EU-WEST-1  (serving Europe, the Middle East, and Africa) AP-NORTHEAST-1  (serving Asia-Pacific regions) QPS Filtering Basic QPS Filtering Options Customers can filter QPS on almost any  targetable keys/values . Some common examples are: Ad Sizes Ads.txt Content Categories Environment Types (App or Site) Geos (Country, City, Region, Zip) Inventory Sources Placement Types Platforms: Device Make, Operating System, etc. Customers can also filter on INCLUDE/EXCLUDE lists of: App Bundles App IDs Domains Placement IDs Site IDs Zip Codes Advanced QPS Filtering Options Customers can utilize  Advanced QPS Filtering  capabilities to filter QPS by user data provided by the customer (cookies, device IDs, or IPs). Fees may apply. Managing QPS Through Traffic Templates QPS delivery to a bidder is managed through traffic templates configured by the Customer Success Manager. These templates use OR boolean logic to define which traffic is sent. Buyer Cloud supports the creation of up to 25 traffic templates per bidder; however, it is strongly recommended to limit the number to fewer than 10 to simplify ongoing management. Best Practices for Traffic Templates Create separate QPS templates for broad targeting dimensions such as: Placement Types Environments Countries Use Advanced Filtering to manage Lists and User IDs. For web-based QPS templates, leverage ads.txt inclusion. Apply global exclusions within each template for: Content Categories Content Ratings Ad Sizes Other frequently excluded key-values Example QPS Traffic Templates Template ID % of Available Traffic Placement Type Country Environment Operating System Estimated QPS 1 100% Banner USA In-App Android, iOS 200,000 2 80% Video USA Web Windows, OSX 20,000 3 50% Banner Canada In-App Android, iOS 5,000 4 100% Native USA In-App Android, iOS 14,000 Monitoring QPS Customers can monitor QPS via Monitoring (see below) and Metamarkets under the Tools tab in the UI:
