Traffic origin

I have unusually high sales today. Is there any way to see where the traffic is coming from to my page in codecanyon?

Envato has analytics which shows you the number of visits your item got each day. It also has a “Referrals” tab showing all of the websites that led to your item, but this information is generalized over the whole month.

To access it go to your item’s page and click Analytics tab.

Also worth noting that an increase in sales does not necessarily mean an increase in traffic.
