# Site Rulesets To create a new ruleset, go to and click "new" in the upper right corner. Give your ruleset a name and optional description of your choice. The **Team** determines who will have access to your ruleset. Choose ruleset **Type** to determine whether your ruleset should apply to inventory, targeting or creative size: * Inventory lets you define a floor price across all advertisers, or a floor price for a specific advertiser. * Targeting means that if you apply a floor price to e.g. semantic targeting, this means that whenever a buyer creates a campaign using semantic targeting, then this campaign cannot bid below the floor price you set. * Creative size lets you set a floor price for a specific width and height. Once you have saved your ruleset, then this ruleset can be applied to the Publisher/Earnings Account, any of your Sites, or any of your Ad Units. On each of these you will have the ability to choose rulesets as shown here:

Apply a ruleset to Publishers/Earnings Accounts, Sites and/or Ad Units.
