Learn where to find the Initial Source property on a profile and understand how it tracks when a person first comes into contact with your brand.
Accessing the initial source information
Initial Source is represented by the Source property in the Information section of a profile, under How They Found You.
The person either entered your site URL directly in their browser or, more likely, we don't know where the person came from.
The person came from another website by clicking a link on that site.
The person either came to your site from a search engine or via a campaign send. You'll see a custom value here if there was a "utm_campaign" set in the URL the person landed on.
