For SEAL Metrics a visitor is the click with:
- empty referrer
- a referrer with a domain different than your domain.
For example, if a hit is loaded and this hit has no referrer, then SEAL understands this hit is coming from Direct traffic.
On the other hand, if a hit is loaded and this hit has a referrer different than your domain, for example, google.com, l.facebook.com,…. then SEAL understands this hit is not a page view, it’s a visitor.
We know this system is not as accurate as a session or unique visitor tracked with a cookie. Even, if the same user is visiting your site three times from SEO, for example, SEAL will count 3 visitors.
This is the more accurate way to count visitors while we are respectful with the privacy of your visitors.
