Optimizely Profile Store is used for storing website visitor profile and behavior data collected by the [tracking functionality](🔗) in Optimizely. The data in Profile Store can then be analyzed and used for personalization and omnichannel marketing actions.

## Get started

Profile Store is the Optimizely customer data platform (CDP) for storing data and making it available for usage by other parts of the Optimizely platform, and external systems.

Examples of data stored from tracking:

• **Visitor profile data** – Email, name, location, devices.

• **Visitor behavior** – Browsing and transaction history.

• **Social interaction** – Comments, reviews.

## Track data to Profile Store

You can track data to Profile Store in any of the following ways:

• Using attributes like `[PageViewTracking]` and `[CommerceTracking]`, for Optimizely Content Management System (CMS) and Optimizely Customized Commerce. See [Page view tracking](🔗) and [Product tracking](🔗).
