This code tracks user activities and events on page and send back following information to the Facebook –
- Which page customer visits
- What product customer views
- What products customer adds to their cart
- What products are actually successfully ordered
- Standard and Custom events specific to website etc.
It also sends few other informations like –
- Browser information
- IP address
- Machine information etc.
So whenever a customer who has logged in to his/her Facebook account visits website using same browser then this customer is tagged as custom audience of this website and his/her activity data is tracked and sent back to the Facebook.
If the user is not logged in to his/her Facebook account and visits the website, then a browser based cookie is placed with necessary activity record in the browser and later on when customer logs in to Facebook using same browser, then it got tagged as custom audience.
Once the customer is tagged, he/she will start seeing ads on his/her Facebook profile. These ads are selected based on the data recieved from the website. This is called Retargetting or Remarketing.
