In HubSpot, every contact record contains two analytics properties: Original source drill-down 1 and Original source drill-down 2.
These drill-downs provide more insight into their original source (i.e., the contact's first visit or interaction with your business). Their values vary depending on the Original source property.
| Original source | Original source drill-down 1 | Original source drill-down 2 |
| Organic search | Search term (if available) | Search engine site |
| Referrals | Referring website domain | Referring website URL |
| Social media | Social media site | Campaign name |
| Email marketing | Campaign name | HubSpot email name |
| Paid search | Campaign name | Search term (if available) |
| Paid social | Social media site | Campaign name |
| Direct traffic | Entrance URL | N/A |
| Other campaigns | Campaign name | Source / Medium |
| Offline sources | Offline channel/tool/platform. Examples include: (e.g., IMPORT, SALES, API, BATCH_UPDATE, CONTACTS_WEB, MOBILE_IOS, SALESFORCE, BOT, CONVERSATIONS) |
Specific offline medium (e.g., BCC_TO_CRM, business-card-scanner, CRM_UI, salesforce-createdby, addMessageUser) |
Some commonly seen values in Original source drill-down 2 include:
- addMessageUser: the record was likely created by a non-bot chat conversation.
- CRM_UI: the record was created in HubSpot manually.
- SIDEKICK: the record was likely created by the HubSpot Sales integration.
- Email integration: the record was likely created by the HubSpot Sales integration or another email integration that is connected to HubSpot.
- Extension: the record was likely created by the HubSpot Sales integration or another email integration that is connected to HubSpot.
- BCC_to_CRM: the record was likely created through logging an email with the BCC or forwarding address.
