Behavior that affects unique visitor count
Unique visitor identifiers are typically stored in a browser cookie. A new unique visitor is counted if they perform any of the following:
- Clears their cache at any time
- Opens a different browser on the same computer. One unique visitor is counted per browser.
- The same person browsing your site on different devices. A separate unique visitor is counted per device. You can use Cross-device analytics to combine visitors together using the People metric.
- Opens a private browsing session (such as Chrome’s Incognito tab).
A new unique visitor is not counted, as long as the cookie identifier is preserved:
- Closes their browser for an extended period
- Upgrades their browser to the latest version
