# Introduction to using Google Analytics with the Developer Data framework

> Discover how linking Google Analytics to the Developer Data framework can help optimize the Unity products you use to build and grow your projects.

Connect your Google Analytics property to the Developer Data framework to improve the quality and completeness of data signals that power your projects' performance with Unity products. With your permission, Unity uses eligible data to better understand player behavior and support optimization capabilities over time.

## Data availability in Unity

When you link Google Analytics to a Unity project, what data is available is determined by the structure and scope of your Google Analytics implementation. For example, if the Google Analytics property is dedicated to a single app, then only data related to that app is available in Unity.

Unity treats the imported data as Developer Data, and uses the data according to your defined [Usage Settings](/cloud/developer-data/data-usage-settings.md) and [Additional Access Settings](/cloud/developer-data/additional-access.md). You're in control of how your data is used, and can update your usage and additional access settings at any time.

## Costs associated with BigQuery and Google Analytics

Integrating your Google Analytics data with the Developer Data framework doesn't incur any additional costs beyond your existing export costs.

> **Note:**
>
> If you notice changes in your export costs after you integrate your Google Analytics data, then [contact Unity Support](https://support.unity.com/hc/en-us/requests/new?).

### Google Analytics properties with existing BigQuery exports

If you already maintain your own BigQuery export, then linking Google Analytics to the Developer Data framework doesn't incur any additional costs. Because Unity leverages your existing export, your streaming and daily export costs in Google Analytics remain the same.

Google continues to charge your project for streaming or daily export costs in accordance with their pricing tiers and policies. For more information, refer to [BigQuery pricing](https://cloud.google.com/bigquery/pricing) (Google).

### Google Analytics properties without existing BigQuery exports

If you don't have any BigQuery exports for the Google Analytics property you're linking to a Unity project, then you aren't charged for any data exported to BigQuery through this integration. Because the export destination is Unity's Google Cloud project, Unity covers the BigQuery export and storage costs for your Google Analytics property.
