I started seeing sales from Facebook here and there. My tracking script picks search string from the referring URL if the particular referrer has been setup properly within the script.

For Facebook I get these two:

- fb_xd_fragment
- www.facebook.com

I wonder what if Facebook has something like "q" for Google or "p" for Yahoo.

Thanks

P.S.
Would this fb_xd_fragment have anything to do with the like button or other type of linking from FB? Thanks.
