Browser Authenticity Test
Comprehensive browser fingerprint analysis. Tests 11+ authenticity signals to see how websites and bot detection systems perceive your browser.
Why Browser Authenticity Matters for SEO
The Connection to Google's NavBoost
Google's leaked API documents from May 2024 revealed NavBoost, a system that uses Chrome browser data to validate user interactions and influence rankings. When your browser fails authenticity checks, your clicks may not count as "GoodClicks" in Google's NavBoost system. Learn more in our detailed analysis: NavBoost Revealed: What the Google API Leak Exposed.
NavBoost tracks a rolling 13-month window of user behavior data including:
- GoodClicks vs BadClicks - Quality of user engagement
- Dwell time - How long users stay on pages
- Navigation patterns - User journey through sites
- Chrome-sourced signals - Data from Chrome browser users
If your browser is flagged as potentially automated or suspicious, your engagement signals may be discounted or ignored entirely, meaning your SEO testing and analysis could be inaccurate. See also: Yandex Leak: User Behavior Signals Explained.
What Each Test Measures
Detection Tests
WebDriver Detection
When navigator.webdriver is true, websites know you're using automation tools like Selenium or Puppeteer. This is the #1 signal that triggers bot detection.
Chrome Object
Chrome browsers automatically have the window.chrome object. Headless Chrome or modified browsers often lack this, immediately flagging them as suspicious.
Fingerprint Tests
WebGL Renderer
Headless browsers use software renderers like SwiftShader or llvmpipe. Real browsers show your actual GPU (NVIDIA, AMD, Intel). This is often the most revealing test.
Canvas Fingerprint
Each browser renders graphics slightly differently based on GPU, drivers, and OS. This creates a unique "fingerprint" that helps identify your device across sessions.
FingerprintJS
An industry-standard library that combines 30+ signals to create a stable visitor ID. Used by major websites for fraud detection and user identification.
Hardware Tests
Hardware Concurrency
Reports logical CPU cores. Most devices have 2-16 cores. Very low values (0-1) suggest virtual machines or restricted environments.
Device Memory
Reports approximate RAM. Some browsers hide this for privacy (which is fine), but very low values like 0.5GB are unusual for modern devices.
Screen Dimensions
Outer window size should always be larger than inner viewport (browser chrome takes space). Inconsistent values suggest manipulation.
Configuration Tests
Browser Plugins
Desktop browsers ship with default plugins (PDF viewer, etc.). Zero plugins is a strong indicator of headless/automation mode.
Languages
The navigator.languages array should contain at least one language. Empty arrays are suspicious.
Platform Consistency
Your platform (Win32, MacIntel, Linux) should match your User-Agent string. Mismatches indicate spoofing or misconfiguration.
How to Improve Your Score
✓ Do This
- • Use Chrome, Firefox, or Safari on desktop
- • Enable JavaScript execution
- • Allow WebGL/hardware acceleration
- • Set 2+ preferred languages
- • Keep browser updated
✗ Avoid This
- • Basic Selenium/Puppeteer without patches
- • Headless mode without proper configuration
- • Blocking canvas/WebGL APIs
- • Virtual machines without GPU passthrough
