For years, I've always had a hunch that it was "optional" mostly because CJ would also provide the "Clickable Link" when site owners choose "Get Code" for advertiser's links. I figured the pixel was there to help generate those mostly inaccurate EPC numbers for each link.
I still have some conversions without using it, but could I be missing conversions/affiliate income by not implementing it? Anyone have any experience working with and without it?
Thanks for your thoughts.
