How are the "original sources" tracked?

How are the “original sources” tracked?

I don’t think organic social (e.g. Instagram) has embedded tracking tags.

How can they be tracked?

Hi @HiYuma,

HubSpot’s original source tracking is explained here: Understand Original and Latest traffic source properties

For social media sites, HubSpot is looking at the referral domain, more on that here: Understand HubSpot's traffic sources in the web traffic analysis tool

Hope this helps!
