Welcome to the Q&A Forum

Hi Everybody, I hope that everyone is having an amazing day and that all is right with the world. As Keszi said, this is an excellent question to email help@moz.com to because you can have a 1:1 correspondence with a customer service representative. Also, we can discuss details concerning the account outside of a public forum. Hopefully this helps and if you have any trouble reaching out to us please feel free to let me know here. Have an awesome day!

As an addition to what Tom has said, you should also setup parameter exclusions in webmaster tools to make sure pages with these appended parameters do not get indexed.

Hi, it helped us rank better for each product page. It allowed me to focus on a single product rather than variations of a product and made our site easier to navigate for the visitor.

As long as the no-cookie variations stays the same, I don't see much practical difference. Either way, the default behavior is equivalent, and users see different content based on geo-location. What Google sees should be essentially the same, and any human editor who looks at the page should realize this is geo-tagging and not any kind of cloaking or deceptive practice. That said, I haven't used this specific tactic, so I'll leave the question open for discussion if community members want to chime in.
