The layout of a specific site might vary from what you see in these pixel setup videos or from the images in the pdf file. The owners of these sites update and upgrade them from time to time. It might also vary depending on what device or browser you use yourself.
If it doesn't look exactly the same as in our tutorial videos or the pdf, first try to figure out yourself where to find the pixel. If that doesn't work just go do a Google search; "How to set up the retargeting pixel for..."
If you still can't figure it out talk to your sponsor and if he or she does not know send us a support ticket.
