Visitor Stitching: Visitor ID

[#1]

The visitor ID attribute is used to identify customers using a value that is guaranteed to be unique to each customer. The value is usually set during a qualifying event -- one that would only occur when a customer provides a reliable means of identification, such as registering or completing a purchase.

How It Works

A simple example of a visitor ID attribute is email address (or email hash). This is typically a reliable way to uniquely identify a customer, especially when it's associated with a qualifying event. In order to accurately perform identity resolution with an email address the following is needed:

• Event Attribute (String) - email_address
  An email address must be part of the data collection as an event attribute.
• Qualifying Event - user_register
  Not all events that send an email address value should be used for identity resolution. Only specific events that have a high likelihood of accurately identifying the customer should be used.
• Visitor Attribute (String) - Email Address
  A visitor string attribute for the email address will associate it with the customer profile for any event that sends the corresponding event attribute.
• Visitor ID - Email Address
  Identity resolution only occurs when Email Address is set and a qualifying event has occurred.
