# Testing CPM Floor Ads Bidding System

We suggest running several A/B tests (but one at a time) to studios to see revenue increase.

### Requirements

* The **Standard Ad Unit IDs** should be populated.
* The **CPM Floor Ad Unit IDs** should be populated.
* [GrowthBook quick setup](/readme/features/growthbook.md#quick-setup) should be completed.

### Getting Started

The CPM Floor system requires specific configuration values to function correctly. These values are normally retrieved from GrowthBook and provided to each studio by their studio manager.

However, for **testing within the Unity Editor or in debug builds**, you must use a custom configuration file (`LionAdsTestRCSettings.json`).

#### Creating a Test Configuration File

1. In your Unity project, navigate to:\
   **`Assets/LionStudios/Resources`**
2. Create a new JSON file named:\
   **`LionAdsTestRCSettings.json`**
3. Populate this file with the test data structure shown below.
   * Replace all **AdUnitIDs** with the CPM Floor ad unit IDs and coefficient values for your project. Please don't put Standard Ad Unit Ids in this case.
   * Set the appropriate **CPMFloorCoefficients** values for each ad unit. (Request it from studio manager.)

{% hint style="danger" %}
When you want to test **GrowthBook data instead** of local test json file, please remove this JSON file or clean data in it. **LionAdsTestRCSettings.json** always overrides GrowthBook Feature Flags **in the Editor** and **debug build**.
{% endhint %}

#### LionAdsTestRCSettings.json sample (You need to add all CPM Floor Ad Unit IDs, not Standard Ad Unit IDs):

```json
{
  "IsUseCPMFloorAdIds": true,
  "CanInterstitialReplaceRewarded": false,
  "CPMFloorSettings": [
    {
      "AdUnitID": "6dd14d0cc03515ab",
      "CPMFloorCoefficients": [
        2,
        1.8,
        1.5
      ]
    },
    {
      "AdUnitID": "5ee2d4708357c9f4",
      "CPMFloorCoefficients": [
        1.2,
        0.9,
        0.8
      ]
    },
    {
      "AdUnitID": "dd97199fe7275224",
      "CPMFloorCoefficients": []
    }
  ]
}
```

#### Test Parameters:

* **IsUseCPMFloorAdIds** (boolean) : Switch on/off between Standard / CPM Floor Bidding systems. We use it to check if CPM Floor Bidding system works correctly or analyze the benefits.
* **CPMFloorSettings** (JSON) : Coefficient settings for adjusting bid request values. This will directly affect ad revenue and fill rates. Please provide these values from your studio manager.
* **CanInterstitialReplaceRewarded** (boolean) : At times, **Interstitial Ads** may generate higher revenue than **Rewarded Ads**.\
  In such cases, we display **Interstitial Ads** in place of **Rewarded Ads**.

{% hint style="success" %}
Please note the use of the **LionAds.TryShowRewarded()** function’s **“onRewarded”** callback.\
If you’re still using **`MaxSdkCallbacks.Rewarded.OnAdReceivedRewardEvent`**, update your implementation to use **our callback** instead.
{% endhint %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://lionstudios.gitbook.io/lionsdk-1.x-legacy-docs/ads/cpm-floor-ads-bidding/a-b-testing-cpm-floor-ads-bidding.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
