What is Tracking Cookie?

A tracking cookie is a system that is deployed on a website to track a user's online behavior. Tracking cookies are deployed automatically when a user accesses a website, often with the hopes of collecting data that is used to influence a user's online purchasing decisions. For example, some cookies are able to determine which websites a user recently visited. As a result, ads for products and services related to their browsing history may be shown to increase the probability of the user making a purchase.
