# User Targeting

Pass user targeting information to ad requests

### General Information <a href="#general-information" id="general-information"></a>

Some networks support adding additional information to improve the ads for the current app context. In addition to [key-value targeting](/ios-integration/advanced/targeting/key-value-targeting.md), AATKit supports [user targeting](https://docs.gravite.net/aatkit/ios/docs/documentation/aatkit/aatusertargeting), allowing to pass information like:

* User ID
* Gender
* Year of birth
* List of keywords

{% hint style="info" %}
Setting the user targeting must be done after initializing AATKit.
{% endhint %}
