We had a week last month when our Facebook traffic increased 2000% within a period of one week. Orders increased quite a bit from FB as well. We didn't run any FB ads during this period and we didn't do anything different for our FB business page other than posting regular content.
Is there a way to find out how this happened? Like a tool to tell me that these sessions are coming from a particular FB post or page? We would like to replicate this if possible.
