Which of these does Google Analytics use to distinguish new and returning users?*All TrafficGeoDemographicsBehavior

Google Analytics uses Behavior to distinguish new and returning users.

Here's a step-by-step explanation:

1. Google Analytics is a tool that helps website owners understand how visitors interact with their website. It collects data about visitor behavior, including how many times they visit, how long they stay, what pages they view, and more.

2. One of the key metrics Google Analytics tracks is new vs. returning users. This helps website owners understand if they are attracting new visitors to their site, and if they are doing a good job of bringing visitors back.

3. To track this, Google Analytics uses cookies. When a user visits a site for the first time, Google Analytics sets a cookie on their browser. This cookie is used to identify the user as a unique visitor.

4. If the user returns to the site, Google Analytics checks for the presence of this cookie. If it's found, the user is identified as a returning user. If it's not found (because the user cleared their cookies, is using a different device, etc.), the user is identified as a new user.

5. So, the answer to your question is Behavior. Google Analytics uses the behavior of users (specifically, whether they have visited before or not) to distinguish new and returning users. It does not use All Traffic, Geo, or Demographics for this specific purpose.
