As a part of its unified auction update, Google is taking away the existing pricing rule options and introduces the new pricing rule feature, dubbed as ‘unified pricing rule’. The idea is to set a common pricing rule to Ad Exchange, Exchange Bidding, Network, Bulk, and Price Priority line items. Technically, you can create a pricing rule which then applies to all the eligible line items – excluding sponsored, and standard.
You can navigate to Inventory > Pricing rules to create a new unified pricing rule. You can select the inventory to apply the rules for, set floor prices or target CPMs and then, save. You can also specify pricing for selected advertisers/buyers/brands optionally while creating a UPR. Learn more about Google UPR.
