There is no active campaigns usually get ad about the visitors to 1 or 2 day (in the past 18 months). My site is more of a scientific experiment, but it's nothing unusual. Suddenly, one day, 50-75 traffic jumped to visitors a day. Poured through Google analytics, Facebook insights, but can't figure out where. All I know is coming to Facebook, not stand alone.

Any thoughts?
