Create and manage yield groups

Make your inventory available to exchanges and ad networks

What are yield groups?

Yield groups allow you to specify what inventory you want to sell with Ad Exchange, Open Bidding, or mediation for mobile apps. Yield groups always include Ad Exchange (unless you use protections to block it), and you can also add third-party exchanges and ad networks. Targeting is similar to line items.

Create a new yield group

Permission to edit yield groups (formerly known as "mediation groups") and edit companies is required to complete these steps. Learn more about user role permissions

We recommend users are added to Teams and then All entities for Yield groups access. Teams restrict access to Yield groups because they restrict access to companies.

If not granted, it may be challenging to manually configure teams access to all Ad networks and Ad units configured within your networks's Yield groups.  Learn more about teams

  1. Sign in to Google Ad Manager.
  2. Click Delivery and then Yield groups.
  3. Click New yield group.
  4. Enter a unique yield group Name that's descriptive for reporting.
  5. Select the Ad format and Inventory type you wish to target with this yield group. These selections determine which ad networks can be added to the yield group, based upon their capabilities.
    • Banner: Display ads for web or mobile apps. For example, a 320x50 leaderboard slot. This includes out-stream video.
    • Interstitial: A full-screen ad to be displayed in a mobile app inventory type.
    • In-stream video: Video ads that appear before, during, and after video content streams.
    • Rewarded: Video ads for mobile apps that allow users to voluntarily watch an ad in exchange for an in-app reward.
    • Native: Custom display or video ads for web or mobile apps that match the user experience in which they’re placed. Can be custom-rendered by the publisher’s mobile app or Google-rendered using Native styles.
  6. Select from the list of Inventory sizes to target. Make sure you choose sizes that correspond with what your exchange or ad network supports. (Optional) 
    • For a "Web" inventory type: all sizes are automatically targeted which requires no additional action (recommended), or select which sizes are eligible.
    • For a "Mobile app" inventory type: all sizes are automatically targeted which requires no additional action (recommended), or select which sizes are eligible. If you add a mediation partner, at least one size is required.
  7. Select from the other customizations including Device category, Device manufacturer, Operating system, and Geography. These settings default to being all-inclusive. (Optional) 
    • For example, if you want to create a mobile-specific yield group, include Device category or Device manufacturer targeting.
  8. Add  targeting to define where in your inventory this yield group can compete for impressions. For the best performance, your targeting criteria should not overlap with targeting for other yield groups. Learn more

    Only target inventory compliant with Ad Exchange policies (unless Ad Exchange is blocked from buying inventory targeted by that yield group).

    Any inventory targeted by a yield group must adhere to Ad Exchange policies unless Ad Exchange is blocked from buying inventory targeted by that yield group. If you use key-values to avoid serving on non-compliant content, make sure you add that key-value to your yield group targeting.

  9. Add additional third-party yield partners to compete for the targeted inventory. (Optional) 
  10. Click Save to confirm your changes without activating this yield group for delivery, or click Save and activate to confirm your changes and immediately approve this yield group for delivery.

Once a yield group has been created and activated, Ad Manager is ready to begin using the yield group to fill requests.

The in-stream video format is supported for Ad Exchange and Open Bidding. Learn more

How many yield groups should I create?
We recommend organizing your yield groups by inventory targeting, not by yield partners. For example, if you want multiple yield partners to fill your news section, create 1 yield group that contains multiple yield partners. This ensures you can take advantage of yield group competition.

Add third-party yield partners to a yield group (Optional) 

By default, Ad Exchange is always included as a yield partner in a new yield group. However, you can choose to block Ad Exchange (or individual Ad Exchange buyers, including Display & Video 360 and the Google Display Network) from a yield group using Inventory Protections.

You also have the option to add third-party yield partners to compete for the inventory being targeted. They can be added after you select the targeting criteria for a new yield group or by editing an existing yield group. You can add up to 10 third-party yield partners to a single yield group, including both Open Bidding yield partners and mediation for mobile apps yield partners, and multiple yield groups (and their additional yield partners) can compete for the same inventory.

Complete the following steps to add a third-party yield partner to a yield group:

  1. Click Delivery and then Yield groups.
  2. Click the name of the yield group you'd like to edit.
  3. Click Add yield partner.
  4. Select the yield partner  from the Yield partner dropdown.

    If you have permission to edit companies, click Create a new yield partner to add a new yield partner in your network.

  5. Select an integration type.
    • Mobile SDK mediation: Choose this option only if the yield partner is supported by the Mobile Ads SDK.
    • Custom event: Use this option to define special label, class name, and parameter values to call custom code in your mobile app. Read the Android and iOS documentation for more details.
    • Open Bidding: Choose this option if the yield partner supports Open Bidding.
  6. Select the Platform you wish to target, either "iOS" or "Android." This selection is only available for the "Mobile SDK mediation" and "Custom event" yield group integration types.
  7. Select a Status of Inactive or Active.
  8. Enter a Default CPM value to manually set the price at which the mediation network will compete, based on your negotiated or average rate for each network.
    • If you have enabled automatic data collection in the Ad Manager company settings, the “Default CPM” value is not used. Instead, the collected value that appears next to Dynamic CPM is used for mediation ranking.
    • To override the Dynamic CPM, select Override Dynamic CPM. If there is no Dynamic CPM, the Default CPM is used and the checkbox will have no effect.
  9. Under "Additional yield partner details," enter any additional required details about this yield partner. This information will enable Ad Manager communicate with the yield partner to fill ad requests.
    • Label: Enter a name for the custom event. This is used in reporting and cannot be changed later.
    • Class name: Enter the name of the custom event class that you will implement in your app code.
    • Parameter (optional): Enter any string you'd like to pass to your custom event when it receives an ad request.
       
  10. Click Save to confirm your changes without activating this yield group for delivery, or click Save and activate to confirm your changes and immediately approve this yield group for delivery.
