I am currently using cid to track paid search. Now I want to add the s_kwcid to gain more details for paid search. The question is, do you have any experience using both parameters simultaneously? Is there any kind of negativ interaction? From my understanding AMO and regular channel settings are completely different and should have no effect on each
To echo @Khurshid_Alam's reply containing a typo, there is NO negative effect. 🙂
You also have the ability, if you want, to send this parameter's value to a separate variable for analysis independent of other tracking codes. I have seen this done and even set up internal campaign tracking codes to avoid cluttering up my external campaign tracking
Just remember, if you decide to do it, to configure your other variable the same as your campaign tracking variable. For instance, if your tracking codes don't expire for a month, you will want to set up your secondary eVar the same way.
