> [!NOTE]
> **Note:** Ad sources are ordered alphabetically.
### Open source and versioned adapters
If an adapter is labeled with "Open source and versioned" in the previous table,
it means the adapter source code is open-sourced in Google's GitHub repository
([Android](https://github.com/googleads/googleads-mobile-android-mediation/tree/main/ThirdPartyAdapters)
or
[iOS](https://github.com/googleads/googleads-mobile-ios-mediation/tree/main/adapters)),
enabling you to debug issues yourself should you choose to do so.
Each adapter is built against a specific version of the third-party ad network
SDK. Follow the specific partner's integration guide for more details.
#### Adapter versioning
React Native adapters follow a `..`
versioning scheme that models the underlying Android and iOS SDK dependencies
for that ad network. If either the Android or iOS dependency gets a major or
minor version bump, the React Native adapter also gets a
corresponding version bump. All other releases get a patch version bump.
> [!IMPORTANT]
> **Important:** Make sure to disable refresh in all third-party ad networks UI for banner ad units used in AdMob Mediation. This prevents a double refresh since AdMob also triggers a refresh based on your banner ad unit's refresh rate.
### Ad source optimization
When you configure multiple ad networks for mediation, you have to
specify what order to request these networks by setting their respective
.
This can be difficult to manage, since ad network performance changes over
time.
[Ad source optimization](https://support.google.com/admob/answer/3379794) is a feature that lets you generate the highest CPM from the ad networks in your mediation chain by automating the process of ordering the mediation chain to maximize revenue.
The previous [mediation networks table](https://developers.google.com/admob/react-native/mediation/choose-networks.md.txt#ad-networks) uses the following values
for ad source optimization support:
| Ad source optimization support | What it means |
|---|---|
| `Bidding only` | The ad network only participates in bidding. Ad source optimization is not applicable. |
| `Country-specific` | eCPM values are automatically updated on your behalf on a per-country basis. This is the optimal type of optimization. |
| `None` | You must manually configure an eCPM value for that ad network. |
Click a specific ad network's guide for details on how to configure
ad source optimization for that network.
> [!NOTE]
> **Note:** Only ad networks that are **Open source and versioned** have specific instructions for setting up ad source optimization on that network.
