Ad Exchange is an inventory management system that empowers you with the option to make informed decisions about your account settings (that is, set up blocks, create channels) to retain more of your inventory worth and increase its value for you and your advertisers.
Rules help you select inventory to target and set pricing guidelines for your selections, and assign prioritization to those rules. Rules also provide the mapping of network partners to their settings via URLs. Learn more about rules.
Protections give you the power to block/allow advertisers, brands, ad technologies, categories and more across Ad Manager and Ad Exchange.
