i'm experimenting with facebook ads. i've chosen for the automatic (integrated option) so shopify placed the FB pixel on checkout (i mean, i didn't copy paste the code there myself).
now my question is: since i have a lot of free (digital) products on my site, i want to make sure i track actual *sales* (for paid products) and not just checkouts of free products. can anyone tell me what the right way is to do that?
you need to paste the Facebook Pixel code between <head> and </head> section. However, I highly recommend connecting your BM, ad account and adding pixel via the Facebook Sales Channel. Learn more about it here: https://help.shopify.com/en/manual/promoting-marketing/analyze-marketing/facebook-pixel
