Visitor ID

The ‘Visitor ID’ dimension provides the unique identifier for each visitor.

Populate this dimension with data

Adobe automatically generates a visitor ID for each visitor. This value is the same as the concatenated value of the visid_high and visid_low columns in data feeds. You can override the automatically generated value with the visitorID variable. See Data column reference for more information.

Dimension items

Dimension items include the unique identifier for each visitor.
