Remarketing questions? In addition to Facebook looking to run YouTube ads.Remarketing questions? In addition to Facebook looking to run YouTube ads. Can I add both FB pixel code and Google tag manager code on to my website. If yes what tips would you suggest not to have issues or conflicts when adding both the codes on to a website. Not looking for any 3rd party tool / tracking as I am a real estate agent in Sydney and not expecting to run huge traffic like any affiliate marketing or ecom product.
