2-3 hours ago, I wrote an article on my website and I got ~350 visitors, mostly from my Facebook fanpage. However, over the last 10 minutes, I've got over 3000 visitors on the article, so I'm wondering if there is any way I can check who shared the link to the article? My Facebook post had like 150 likes and 35 shares, but I can see only 5-6 shares and no one of the people who shared it has many followers/friends. So I suppose someone else shared it, but is there any way to check it? Thanks!
