We noticed in Google Analytics and Moz that our blog uwishunu.com got a major traffic spike to this particular post: http://www.uwishunu.com/2013/11/roundup-top-places-to-view-holiday-lights-in-and-around-philadelphia-this-season/ (you can see the like button currently says 35k likes!)
In Moz and GA we can see that this traffic is from Facebook. We suspect that a brand page or local celebrity with a lot of followers shared this link with their fans. Is there any way to see who that may have been so we can thank them (and see if they'll do it again sometime!) ??
