These rules are defined at scope to be re-used on any sites and can be fine-tuned by media type and size. ### How to Create a Floor Rule 1. **Go to the Rules \> Floor Price section** in the menu platform. 2. Click on **"New rule"** to open the rule creation form. ### Step-by-Step - **Identification** Give your rule a clear and descriptive name (e.g. `my banner floor rule` ). - **Default Floor Price** Set a global default floor value. Currency adapts itself to the scope settings. This value applies unless a more specific rule (mediatype/size) overrides it. - **Granular Rules** (Optional) Click **"Add setting"** to define specific floor prices for: - **Mediatypes**: Choose the mediatype format(s) the rule should apply to (e.g. `banner`). - **Sizes** (optional): Further narrow down the rule by creative size (e.g. 300x250). - **Price**: Set the floor price for this specific condition. You can add multiple granular rules by repeating this step. You can also delete it with the bin icon. > 💡 You must define at least one media type in each granular rule. Sizes are optional. - **Dynamic Floor** By default, a dynamic floor mechanism is enabled. This ensures that the **highest bidding price** from the prebid auction is sent to the ad server as the floor price. This helps optimize competition and performance in GAM. A toggle allows the user to **disable dynamic floors** if they prefer to rely solely on static pricing rules. ### Functional Use The price defined in a floor rule is used to construct a **Prebid-compliant floor schema**, which is injected into the auction request via the **Prebid Floor Price Module** to be sent to participating **SSPs** to enforce minimum pricing at auction level. ### Saving the Rule Once your rule is complete, click **“Save rule”** to apply it. The rule will immediately impact eligible adunits in the stacks where it is synced and deployed. ![image (5)](https://help.pubstack.io/hs-fs/hubfs/image%20(5).png?width=688&height=185&name=image%20(5).png) Once created, all floor price rules are listed in the **Floor price** section of the platform. This view allows you to manage, edit, and monitor the status of each rule. ### List Overview Each rule is displayed with the following key information: - **Rule name**: The name defined by the user (e.g. `My floor rule`). - **Default floor**: The base CPM floor defined in the rule. - **Sub**: Number of specific sub-rules created for this rule (based on `mediatype` and `size`). - **Used on**: Indicates how many **stacks** currently use this rule. ### Actions - **Edit** (✏️ icon): Opens the rule editor where you can update the default floor or add/edit granular rules. - **Read-only** (greyed out): “No floor price” cannot be edited ### History Everyone can access the history. The last 5 versions of each rules are displayed by default. Others can be accessible by clicking on a button.![Capture d’écran 2025-01-09 à 14.16.18](https://help.pubstack.io/hs-fs/hubfs/Capture%20d%E2%80%99%C3%A9cran%202025-01-09%20%C3%A0%2014.16.18.png?width=688&height=392&name=Capture%20d%E2%80%99%C3%A9cran%202025-01-09%20%C3%A0%2014.16.18.png) The only difference between Pubstack and customers is that Pubstackers will see real pubstack e-mail while other users will see “Pubstack” : - [What is Pubstack](https://help.pubstack.io/migration/what-is-pubstack?hsLang=en#main-content) - [Solutions description](https://help.pubstack.io/migration/what-is-pubstack?hsLang=en#solutions-description) - [Demo and trial](https://help.pubstack.io/migration/what-is-pubstack?hsLang=en#demo-and-trial) - [Analytics](https://help.pubstack.io/migration/analytics?hsLang=en#main-content) - [The Pubstack interface](https://help.pubstack.io/migration/analytics?hsLang=en#the-pubstack-interface) - [Technical documentation](https://help.pubstack.io/migration/analytics?hsLang=en#technical-documentation) - [Use cases](https://help.pubstack.io/migration/analytics?hsLang=en#use-cases) - [Ad servers](https://help.pubstack.io/migration/analytics?hsLang=en#ad-servers) - [API](https://help.pubstack.io/migration/analytics?hsLang=en#api) - [Ad Management (One)](https://help.pubstack.io/migration/ad-management-one?hsLang=en#main-content) - [Implementation](https://help.pubstack.io/migration/ad-management-one?hsLang=en#implementation) - [Technical Documentation](https://help.pubstack.io/migration/ad-management-one?hsLang=en#technical-documentation) - [Pubstack UI Ad Management](https://help.pubstack.io/migration/ad-management-one?hsLang=en#pubstack-ui-ad-management) - [Use Cases](https://help.pubstack.io/migration/ad-management-one?hsLang=en#use-cases) - [Features](https://help.pubstack.io/migration/ad-management-one?hsLang=en#features) - [Knowledge](https://help.pubstack.io/migration/knowledge?hsLang=en#main-content) - [Infographics](https://help.pubstack.io/migration/knowledge?hsLang=en#infographics) - [Technical Documentation](https://help.pubstack.io/migration/technical-documentation?hsLang=en) - [The Pubstack Academy](https://help.pubstack.io/migration/the-pubstack-academy?hsLang=en#main-content) - [User-Guides](https://help.pubstack.io/migration/the-pubstack-academy?hsLang=en#user-guides) - [Webinar Episodes](https://help.pubstack.io/migration/the-pubstack-academy?hsLang=en#webinar-episodes) - [How to contact Support ?](https://help.pubstack.io/migration/how-to-contact-support?hsLang=en) - [Pubstack Node](https://help.pubstack.io/migration/pubstack-node?hsLang=en#main-content) - [Introduction](https://help.pubstack.io/migration/pubstack-node?hsLang=en#introduction) - [Getting Started](https://help.pubstack.io/migration/pubstack-node?hsLang=en#getting-started) - [Analytics](https://help.pubstack.io/migration/pubstack-node?hsLang=en#analytics) - [Rules](https://help.pubstack.io/migration/pubstack-node?hsLang=en#rules) - [Monetisation Management](https://help.pubstack.io/migration/pubstack-node?hsLang=en#monetisation-management) [![Chill listening crop-3](https://help.pubstack.io/hs-fs/hubfs/pubstack_logo.png?width=89&height=24&name=pubstack_logo.png "Chill listening crop-3")](http://www.pubstack.io?hsLang=en) We help publishers thrive in a complex programmatic world Copyright © 2026, Pubstack
