You may have noticed the ngroup parameter in your guide sharing link (see below).
This parameter gives you additional data about how your guides are being used. It lets you see how your guides are performing across different distribution channels. For example, you could see how many times a guide has been viewed through an email link vs a live chat link.
Of course, you could remove this parameter, but then we won't be able to show you the data for specific distribution channels. It's totally up to you!
