What is the &_kx= string at the end of my URLs and can it be switched off?
Hi everyone and happy Friday!
We have the normal UTM tracking on our links and we have added a custom utm_lc to track the “last click” source on a profile.
but Im seeing another code on the end of our links that I can find the source of, the &_kx= and this string can get quite long and messy looking:
?utm_source=Klaviyo&utm_medium=email&utm_campaign=Testing_1&utm_lc=Klaviyo&_kx=u7eRR65NqnLZ15DPx3ylMy9oSyyH_ttWWReiaicE1yg%3D.TLh3LF
Is this an important string, what is it measuring/writing back to and is it editable/switch offable?
Thank you
