## Requirements

Set **Data Enrichment for the Tealium Collect tag** to **Frequent**. For more information, see the [Tealium Collect Setup Guide](https://docs.tealium.com/tealium-collect-tag/).

After you complete the integration, audiences are automatically sent to Optimizely with data layer enrichment.

## Integrate Optimizely Classic with AudienceStream

There are two steps to integrate Optimizely Classic with AudienceStream:

1. Add `utag.sync.js` to your site.
1. Connect AudienceStream and Optimizely by using the Tealium Tool: Optimizely Helper.

### Add utag.sync.js to your site

You need to include `utag.sync.js` in all HTML pages that need to use Optimizely. For consistency, you may want to include it in all pages.

For details on setting up `utag.sync.js`, see [Using the utag.sync.js Script](https://docs.tealium.com/utag-sync/).

### Connect AudienceStream and Optimizely

To use audiences in Optimizely, you need to connect AudienceStream and Optimizely and then map audiences to your Optimizely project. Use the Tealium Tool: Optimizely Helper to complete both of these tasks.

For more information, see [Tealium Tool: Optimizely Helper](https://docs.tealium.com/optimizely-helper/).

## Integrate Optimizely X with AudienceStream

Use the Optimizely Dashboard to integrate Optimizely X with AudienceStream.

1. After creating your Audiences in AudienceStream, log into Optimizely and click **Integrations**.
1. Set Tealium to **On**.
1. Enter your Tealium account ID.
1. Select the **Overview** tab, then click **Audiences**.

1. Create a new experiment, or edit an existing experiment, and click **Audiences**.
1. Click **Add a Saved Audience** and select the audience to target.
1. Save your experiment.
