Hi @yuravw,
Thanks for reaching out. These additional URL parameters which you highlighted are as a result of cross domain tracking with Google Analytics, typically used to ensure variations of your site URL are attributed to the same Analytics property.
It’s common for users of sites with language variations, or AMP users who have a canonical (non AMP) and an AMP version. You’ll find more information on this below:

As this additional URL parameter may be set up from your Google Analytics configurations, you can also check for any configurations at Analytics level. There are no cross domain configurations within Site Kit. If you need assistance checking your Analytics configurations from analytics.google.com, for any cross domain tracking configurations, you can reach out at the Google Analytics Help Center, where the product experts would have more insights than we have here in Site Kit plugin support.
