How can I make it so that third-party traffic is taken into account separately in the metric?

Question

PHP

I have a metric counter installed on my site.
Traffic comes from search engines.
Now I want to send traffic from another site and I need to take it into account somehow so that it can be seen in the metrics that this is third-party traffic.
How to do?

Answer 1

In the link on this site, specify some parameter:
http://my-site.ru/?from=my-partner

Answer 2

The metric already determines where the traffic comes from. Nothing to share

Answer 3

Labels were created for this.
