Tracking referrals from non-internet resources

Question

One can see the URL of the site (also called referrers) which pushed the visitor to your site.

The site owner can also share links to non-website based sources such as chat software, email etc.

I was trying to understand how can one track non-website based referrers in Google analytics such as:

• User coming from email links
• User clicking from chat messages

Answer 1

You have to add URL parameters to track a visitor from external sources that do not provide referrer data.
