How to Use
- 1
Enter a URL to analyze (e.g., "https://example.com"). The URL must be publicly accessible.
- 2
Click "Analyze" to start the performance check. The server fetches the page and measures timing and structure.
- 3
Review the results -- each of the 10 performance checks shows a pass/fail status with details about what was found.
- 4
Check the overall score (0-100) to get a quick summary of the page's performance health.
10 Performance Checks
- HTTPS -- Verifies the page is served over a secure connection
- HTML Size -- Checks if the HTML document size is within optimal range
- Response Time -- Measures server response time for the initial request
- Scripts -- Counts the number of script tags and evaluates impact
- Stylesheets -- Checks external stylesheet count and loading strategy
- Viewport -- Ensures a viewport meta tag is present for mobile responsiveness
- Title -- Validates that the page has a title tag
- Meta Description -- Checks for a meta description tag
- Images -- Evaluates image optimization and alt text usage
- Minification -- Detects whether HTML appears to be minified
The Page Speed Analyzer performs a server-side fetch of the target URL. Pages that require authentication or block server-side requests may not return accurate results.
