I want to advertise a physical product I have on Facebook. It is called MapArt (http://patrickloonstra.nl/mapart) and when I give it attention it sell, so at the moment there is money waiting for me.

I hate trackers and cookie consents, so I hesitate to use the FB pixel to optimize the advertising.

Yes, I can advertise without it, but I have the idea that I am missing opportunities and conversion then. But is that true?
