How do we track the known and unknown visitors in Smart URL?
Known visitors are usually identified by the information they have provided, including sign-up forms that might contain their email, name, or other data. At first, even known visitors are only identified with the cookie value assigned to them. The system recognizes these visitors when they interact with your website/campaigns and compares the information against their cookie value. If their information already exists in the database, it marks the information to their cookie value and can be used to identify the visitor in the future easily.
Unknown visitors, on the other hand, may have not provided any identifiable information to MA. So they will be considered anonymous until specific data is found. They are usually tracked with cookie information and session IDs, even if they are a returning visitor until further information is tagged to that visitor via a sign up, forms, or contacts import through integration.
It should be noted that the Tracking code script should be enabled in the website in order to perform the tracking functions.
