What is Website Privacy Score?
A rating that evaluates how well a website respects visitor privacy, based on trackers, cookies, security headers, third-party requests, and fingerprinting.
A website privacy score quantifies how much a website tracks and exposes its visitors.
What's Evaluated
- Trackers: Google Analytics, Facebook Pixel, and other tracking scripts
- Cookies: How many, from whom, and how long they persist
- Security headers: CSP, HSTS, X-Frame-Options, Permissions-Policy
- Third-party requests: How many external domains are contacted
- HTTPS: Is the connection properly encrypted?
- Fingerprinting: Does the site use canvas fingerprinting or other techniques?
Grading
Scores typically range from A (excellent privacy) to F (severe privacy concerns):
- A: Minimal trackers, strong security headers, no fingerprinting
- B: Few trackers, decent headers
- C: Average — some trackers, missing some headers
- D: Multiple trackers, weak security
- F: Extensive tracking, poor security, fingerprinting
