answers to common questions

Browser Info Checker FAQ

What exactly does the Browser Info Checker reveal?

It reveals your full user agent string, operating system, browser version, screen resolution, color depth, timezone, language preferences, installed plugins, WebGL vendor/renderer, canvas fingerprint hash, network connection type, and dozens of navigator properties used for SEO debugging.

Is this tool useful for technical SEO audits?

Absolutely. Compare your browser fingerprint with Googlebot's known user agent, detect client-side rendering differences, check if your lazy loading or JavaScript works across headless browsers, and ensure Core Web Vitals match real user conditions.

Does it store my browser data?

No. All analysis runs in your browser using JavaScript. We don’t send any data to servers, no logs, no tracking. Privacy is guaranteed.

Can I detect if a visitor is a bot?

While no tool is 100% foolproof, WebGL/canvas fingerprinting and headless browser detection help flag suspicious patterns. Use it alongside other signals for fraud prevention.

Is there a rate limit or API key needed?

Not for the free web tool. Unlimited usage, no signup. For programmatic access, contact sales for enterprise API.

How accurate is the geolocation via timezone?

Timezone + language + locale headers provide region hints accurate at country/city level, not exact IP coordinates, but enough for localization QA and hreflang testing.

Does it work on mobile browsers?

Yes, fully responsive. On iOS and Android it captures screen dimensions, touch support, device model via user agent and viewport data.

Can I export the report?

You can copy all data points as JSON or text. Perfect for attaching to bug tickets or client SEO reports.
