I read this reference https://www.codehousegroup.com/insight-and-inspiration/digital-strategy/sitecore-analytics-vs-google-analytics
There said that Google Analytics cannot track visitor profiles
Is it true?
I have installed Google Analytics on my website. I want to analyze the user's profile data that has been logged. How do I do that?
You have to track userId, an hash of your user's crm id or his email that you know when the user is logged: https://support.google.com/analytics/answer/3123662?hl=en
You can track it as custom dimension too at user level.
