How to Use Browser Engine in SEO Checker

Vovsoft SEO Checker is a website analyzer and SEO audit tool for Microsoft Windows. In this page, we explain how to use the built-in browser engine.

Some websites only return a proper HTML response when accessed through a real web browser. These sites may rely on JavaScript, browser APIs, or session handling, and often return incomplete or empty HTML to basic scrapers. The "Use Browser Engine" option solves this by loading pages as a real browser would.

Modern websites often rely on JavaScript, dynamic loading, and user authentication. Traditional SEO tools that fetch raw HTML may fail to analyze these pages correctly. To solve this, Vovsoft SEO Checker includes a Use Browser Engine option powered by Microsoft Edge WebView2.

This feature allows the software to load and analyze pages exactly as they appear in a real web browser.

What Is the Browser Engine?

The Browser Engine uses the Chromium-based Microsoft Edge WebView2 control to render web pages like a modern desktop browser. Unlike basic scraping methods, it fully processes:

• JavaScript-rendered content
• Dynamically loaded elements
• Single-page applications (SPAs)
• Cookies, sessions, and authenticated logins

This ensures that SEO data is collected from the fully rendered page, not from incomplete or preloaded HTML.

When Should You Use the Browser Engine?

You should enable Use Browser Engine when working with:

• JavaScript-heavy websites
• Pages that load content dynamically
• Login-required or password-protected pages
• Websites that restrict or block simple crawlers

For simple static pages, the default mode may be faster. For modern websites, the browser engine provides more accurate results.

👉How to Use the Browser Engine

Logging In to Websites

A key advantage of the browser engine is the ability to log in directly within the tool. This makes it possible to analyze pages that are normally inaccessible to standard SEO tools, such as:

• Member-only pages
• User dashboards
• Admin or control panels

The browser engine maintains the session, allowing SEO Checker to extract data from protected pages reliably.

Benefits for SEO Analysis

Using the browser engine allows you to:

• Analyze fully rendered page content
• Extract SEO data from JavaScript-based sites
• Access login-required pages
• Get results that closely match what users see in real browsers

This leads to more realistic and dependable analysis.

Notes and Tips

• Browser-based analysis may be slightly slower than basic scraping
• Microsoft Edge WebView2 is automatically available on most Windows systems (Windows 10 version 1709 or later)
• The WebView2Loader.dll file is required for proper operation and is included with the software.
• Enable this option only when needed for best performance

Conclusion

The Use Browser Engine feature significantly improves compatibility with modern websites. By rendering pages with a real browser engine, Vovsoft SEO Checker overcomes common scraping limitations and enables accurate SEO analysis of dynamic and authenticated pages.

For websites built with modern web technologies, this option can make a noticeable difference in results.
