Here is the playlist where you can find videos on how to setup your GTM and Analytics for your Website Platform:    • How to Setup Tracking  

This video is going to help you setup your Facebook Pixel on your Website with GTM (Google Tag Manager).
Couldn't find any good videos explaining the logic behind how to set up the pixel so it also gathers information about the products a visitor have clicked on and the different values that are needed for good tracking and optimisation for your ads. Especially when it comes to dynamic ads the pixel needs specific information so that it shows exactly the product the visitor has looked at.

Hope this helps you and saves you a lot of time searching.
