ca_user_location - what is this cookie used for and why would it impact AA Marketing Channels?

Question

AEM experts!

Our Adobe Analytics Marketing Channels volume dropped after we migrated a site to AEM. Specifically, Natural Search (mostly Google).

We managed to isolate it to a cookie 🍪 ca_user_location causing the document.referrer to change to itself if not present already.

If anyone is familiar with AEM and has set that cookie before and can explain (hopefully) what it’s used for it would be really helpful. I also wonder if it’s something with Google and privacy …. 🙏

Since you already identified the cause, search your AEM application code base for what the ca_user_location cookie does in your code. As per your suggestion, it probably has a logic that modifies the document.referrer. Analyze the need for the above cookie and modify the code. If the code is written well, there must be some comments explaining the behavior.

Good luck!

@sdelazz it looks like ca_user_location cookie is a custom cookie set by either in AEM or in a rule of Adobe launch. Please debug your code.
