I do not know what ".com/?c=f25a9a5f951d" means

Question

I have a ecomm (wordpress and woocommerce/aliexpress) website. For some reason, that I cannot find an answer to, every URL appends this parameter "?c=f25a9a5f951d" (actually there are two different ones but answering one should do the trick). I know that ?v=hash is for location but what is ?c=hash mean? Has anyone experienced this?

If so, I need some insight into: 1. what does it mean? 2. why is it appearing? 3. how do I remove it or can should I?

website is https://poppyandmia.com

Any help is much appreciated.

Answer 1

That's a GET variable (i.e. the variable is c and f25a9a5f951d is its value). It is used to "transport" a certain value from one page to the next one (for example an item ID) and can be read out with PHP like $my_value = $_GET['c'];
