In your server logs the referrer field most times contains where the visitor came from.
You could setup a script to parse the referrer and print the results. I rely more on the server logs than in the analytics as I have full control on the server end. Some hosts also have some sort of tracking for visits which effectively parses the logs, you could check that too from your cpanel in case is there.
