I am have the same issue on my site, all my links also have a ?kuid attached to them. I thought it was something I had added to the header/footer code a while ago for one of my sales funnel platforms. But after doing some more research trying to figure out how to remove them, I have learned its not from anything I added. Still haven’t been able to figure out why they’re there or what’s causing them. When I view page source and search for “kuid” it also says nothing found in there. If anyone has any suggestions, they’d be much appreciated!
