Google Analytics New vs Returning is not as New as it would appear.
Whenever the same ‘User’ visits a website, for the first time, on a difference or even a different web browser on the same device it will trigger a ‘New’ User type in the Google Analytics account that is tracking that website.
Compounding this, is each & every time the same User, visits the website with private browsing or incognito browsing enabled it will trigger a New User type for each & every website visit.
So What’s New then?!
