Tracking to the Optimizely Content Recommendations service must come from domains on the allow list to approve permitted data and to avoid tracking unintended data, which could impact your data volume and your license cost. Each domain from which you collect data \_must_be placed on the allow list for data to properly be received into the service.

• **If you are using [Tag Manager](🔗) to track data** The allow list is done at the tag level and is configured by your Onboarding Project Manager or Application Support when they configure your tracking tags.

• **If you are using the [NuGet package](🔗) to track data** Go to **Settings > Configuration** in your Content Recommendations portal to place domains on the allow list.
