Unique visitors (or users) represent individual people visiting your website. Each person is counted once during a time period, regardless of how many visits they make.
How unique visitors are tracked
Traditional methods:
- Cookies: Most common, but can be blocked
- Browser fingerprinting: Less accurate, privacy concerns
- Logged-in users: Most accurate for logged-in sites
Unique visitors vs sessions
| Scenario | Visitors | Sessions | |----------|----------|----------| | 1 person, 1 visit | 1 | 1 | | 1 person, 3 visits | 1 | 3 | | 3 people, 1 visit each | 3 | 3 |
Limitations
Unique visitor counts can be inaccurate due to:
- Multiple devices per person
- Cleared cookies
- Private/incognito browsing
- Ad blockers

It auto-detects Shopify and WooCommerce so you can connect visitor trends to actual revenue, and it alerts you when visitor counts drop unexpectedly. You find out in hours, not weeks, when something is quietly cutting your audience in half.
