Recently a question of mine got an unusual surge in upvotes, I guess I may have been linked from some high visibility blog or something like that.
Is there any way to know the traffic sources for a question?
This might not be the most accurate, but you can search for link backs on google like this.
Also, I'm not sure which question you're referring to, so I used your most viewed question as an example.
Just copy the URL of the question you want to know about.
Go to Google
Type link:
Paste the URL after link: (space)
Click search
I'm guessing you got a lot of views for your most viewed question from the bitcoin result.
