Upon setting up the Facebook channel, one can add a pixel for tracking customer behavior and data on his online store. For using a Facebook pixel, one has to set a customer data sharing level. The store owner himself decides how much data does he intend to track via the pixel. To add a Facebook pixel, one either uses the Facebook channel or the Facebook Ads Manager.
By the Standard data sharing setting, one gets information regarding customer behavior only. But, when one switches over to the Enhanced and Maximum setting; one accesses additional customer information. This covers email address, location, and name.
The key advantage of using Facebook pixels is that they boost the performance of Facebook ads and the marketing capabilities of your store. One creates a Facebook ad after connecting to a Facebook Ad account.
