In the main dashboard of your Shift4Shop Online Store Manager you will see a readout of your store's traffic. Also, by going to Reports >Statistics and viewing the Visitors/Hits reports you can also see information about your store's visitors.
To better understand the information given in these reports, it would help to know how the visitors are individually tracked.
When someone visits your store, a unique cookie is stored into their browser and it is counted as a visit. The two most important things to note about this cookie are that A) it is stored in the visitor's browser and B) it expires after 8 hours of inactivity
So, based on the above, here are some example scenarios and how they will be reported:
A shopper comes to your store and leaves, but comes back to visit 2 or 3 hours later.
They will be counted as one visit
The cookie hadn't expired yet.
A shopper comes to your store and leaves, but comes back to visit 10 hours later
They will be counted as two visit
The cookie expires after 8 hours of no activity.
A shopper comes to your store and their browser (i.e. Firefox) crashes. So they immediately visit your store using a different browser (i.e. Chrome).
They will be counted as two visits
The cookie is stored in the visitor's browser and the visitor used two separate browsers.
You have a physical location (i.e. a brick and mortar store or trade show) where your employees place orders online for customers, in-person, on the same browser
All those customers will be counted as one visit
The cookie is browser based
There's constant activity, so the cookie doesn't get to expire until closing time
