I noticed one of the links I added shows the following when I hover over it with my mouse:
http://www.example.com/?ref=reliefmine.com
Is this what modern websites do now since the HTTP-REFERRER header is no longer guaranteed to work? If so, where can I lean more about this?
Thank you!
The term Ghost uses for this is “outbound link tagging”, and it’s pretty similar to the referrer header, with the exception that it more used to answer “who sent you here”, rather than “where did you come from”. There’s various parameters that have been used (utm_source, anyone?) in the past, and it seems that ref is the modern one.
