Source tracking : Referral Website

Summary:

Dear support, 

My client does not understand the source tracking : Referral Website. 

I saw in the documentation : 

The candidate originated from any other referral website.

Example:

   • Source Medium: Referral Website

   • Source: Referral website domain

   • Career Site: <Career Site Name>

But it is not clear at all. What does it means "Any other referral Website" ? 

Could you please explain what does it mean "Any other referral Website" and could you please give us some case (example) where this source tracking will appear ? 

We need to clarify this source tracking. 

Thank you for your help, 

Audrey Corbellini
