How do facebook conversion pixels work?
It's been long time since I discovered Facebook pixel, however, I haven't had time or courage to find more about how it works and learn how to use it and make use of the data it does provide.
Can you please explain scenarios in which you use Facebook pixel, how do you implement it, and what data do you check when using it. How does it help your business?
If you have some good references to learn from, I'd appreciate if you could post links. Free materials preferably.
