Original source drill-down 1 and Original source drill-down 2 are two analytics properties included on every HubSpot contact record. Older HubSpot accounts may have the properties Original source data 1 and Original source data 2 instead, which contain the same information.
These properties store further information about the source of the contact's first visit. Their values vary depending on the Original source property.
