# Implement placements in your project

> Implement placements in the Unity Ads SDK integrated in your app code.

Do the following to implement placements in your project:

1. Initialize the Unity Ads SDK early in the project's run-time lifecycle, preferably at launch. The recommended best practice is to use the latest SDK.
2. In your app code, check if content is ready to display through your specified placement.
3. Programmatically retrieve the available content and display it.

For comprehensive code integration instructions to implement interstitial, rewarded, and banner ads, read the respective documentation for your development platform:
