Does the browser have an ID?

Published in Web Personalization 1 min read

Yes, in the context of Sitecore Personalize, the browser effectively has an ID assigned to it.

Sitecore Personalize assigns a universally unique identifier (UUID), referred to as the browser ID, to each user of your application. This ID is crucial for tracking and associating user activity across sessions, events, and orders.

Here's a breakdown:

  • Purpose: The browser ID allows Sitecore Personalize to recognize and track individual users even if they haven't explicitly logged in or provided personal information.
  • Functionality: It serves as a persistent identifier, enabling personalized experiences based on accumulated user behavior.
  • Mechanism: The browser ID is typically stored as a cookie or using other browser storage mechanisms, allowing Sitecore Personalize to retrieve it on subsequent visits.
  • Uniqueness: Each user's browser is assigned a unique ID, ensuring that data is correctly attributed to the individual user.

In summary, while the browser itself doesn't inherently have a built-in ID in the traditional sense, Sitecore Personalize assigns a unique identifier to each browser instance to track and personalize the user experience. This assigned ID functions as the user's identifier within the Sitecore Personalize ecosystem.
