Mediation groups
Mediation groups is located right next to the Ad Units tab.
Mediation Groups are used to streamline targeting and mediation settings that can be applied across different ad types within the same mediation engine. They simplify the mediation process by enabling a single set of configurations to be applied automatically to relevant waterfall setups based on predefined targeting. Using Mediation groups you can move ad unit positions around with the “drag and drop” function and organize them into country/segment groupings that are easy to create. In other words, you can manage your waterfall configuration in a number of ways. Whenever you create a new app, we automatically add a “Default” mediation group, where all the ad units are located in the Automatic Priority section for each ad type. By default, this mediation group is applied to all countries/segments. If you add the ad unit to the custom priority, it will override the "countries" setting for this ad unit. Thus it can work for the country which is not selected in the settings of this ad unit. You can create new mediation groups for the specific mediation or targeting by clicking the “New Mediation group” button.
First, you need to add the name of your mediation group. We advise you to name it by the countries/segments names you want to target this priority to including the mediation engine it will use. Then you need to choose whether you want to target this mediation group to a range of countries or for some segments. You can select one country as a group or a number of countries for the configuration. However, you can't use the same country in several groupings (for example, if you choose Canada, USA, and Australia for one of the country groupings, you can't feature Canada in another grouping). The same principle applies to the Segments targeting.
Then you need to choose the mediation you plan to use for this mediation group. After that click “Save” to create a mediation group. Waterfall configurations for each ad type for saved mediation groups will be created automatically. Finally you need to actualize the ad units positioning in the waterfall for all ad types.
If you chose Appodeal mediation, there are four modes you can utilize:
- In-App Header Bidding
- Manual Priority
- eCPM Priority
- Automatic Priority
On the left, you can see the tab Unused ad units — that's where the newly created and previously unused ad units are placed, so you can drag all the ad units you'd like to use for Priority Modes. Keep in mind that in this section you can't create new ad units. For that, you'd need to use the Ad Units tool.
In most cases, it's recommended to add ad units to the Automatic Priority, where they are positioned automatically (based on the statistics at our disposal). You can also use the “Move all unused ad units here” button to move all the ad units from the Unused ad units section to the Automatic Priority. Note that ad units in this section are sorted by their names.
eCPM priority is in-between Automatic and Manual priorities and allows specifying eCPM for each ad unit for further automatic positioning.
In Manual Priority, you can arrange top positions: ad units that go first. Manual Priority is basically for your preferred ad units that you want to “release” as a priority in the waterfall. You can choose up to 3 ad units for one position. In fact, it means that every time will be randomly selected one of the specified ad units and placed in the corresponding position in the waterfall.
In-App Header Bidding priority should be used only for in-app header bidding ad units if you have created them previously in the ad units section. Here you can either set up price floors manually or select the Auto Price Floors option.
Please choose Auto Price Floors option for In-App Header Bidding for now.
Not all ad networks support in-app header bidding.
All four modes are functioning simultaneously. If an ad unit is displayed in the list in a muted state, that means it can't be added to the waterfall associated with this priority for the reason this ad unit was switched off in the Ad Units tool. If you choose Applovin MAX or LevelPlay mediation during mediation group creation, there is only one mode you can utilize - Automatic priority. If you plan to use the Amazon ad network with custom mediations, you need to place the Amazon unit in the Amazon section. You can’t create mediation ad units on your own, ad units will be added automatically after your app meets restrictions of custom mediation.
To find this tool navigate to the Mediation Setup > Ad Networks tab. To check if custom mediation was already integrated for any of your app navigate to the Mediation Setup > Mediations:
