Tracking consists of a service and a set of NuGet packages for the client-side tracking. As part of the onboarding, Optimizely sends the required configuration keys and credentials to the technical contact for your project.
To collect data about visitor interaction, tracking must be added to every content type of the website, such as pages, blocks, media, product category, products, variants. You can also add tracking to emails used in campaign mailings.
Adding tracking can simply be done through decorating a content controller action method with an attribute. However, in most cases, more site-specific custom code is required to ensure that data for tracked events is collected correctly.
The collected data can be used for:
Content Recommendations for Optimizely CMS.
Product Recommendations for Optimizely Commerce.
Build profile information including conversions like clicks, purchases, or opened emails.
Data visualization in Optimizely Visitor Intelligence and the Optimizely Personalization Portal.
The tracking also supports tracking of data to any source outside the Optimizely platform.
The tracking service includes product-specific tracking for Optimizely CMS and Commerce, to support data visualization with different output platforms. To get tracking running for a site, you need to configure access to the tracking API. There are separate integration methods to connect with the tracking service, and separate native integrations depending on the product for which you are configuring tracking. See Install and configure personalization.
