Let's say someone clicks a link for my blog acme.com.
Is it possible to determine the source that they came from? By source I mean, can I tell whether they clicked on this link from Facebook or Google or another blog?
This is operating under the assumption that they had to enter my site from clicking a link.
I'm also assuming that I don't have any trackers on this user and it is their first time visiting my website. And I don't have access to Google Analytics.
