Why Monitor Website Performance?

A one-time performance test is a snapshot in time. Your website changes constantly - new features, content updates, third-party scripts, and infrastructure changes all affect performance. Monitoring catches these changes before they impact your users.

W3Test monitoring runs automated W3Test tests on your schedule, tracks scores over time, and alerts you when performance drops below your threshold.

Best Practices for Monitoring

Test After Every Deployment

Add performance checks to your CI/CD pipeline. Always test immediately after major releases.

Set Alert Thresholds

Configure thresholds that match your goals. If your performance drops by more than 10 points, you should know.

Watch Third-Party Scripts

Third-party scripts are the most common cause of slow-downs. Monitoring helps you identify exactly when they were added.

Compare Mobile and Desktop

Mobile users experience slower connections. Monitor both to catch mobile-specific issues.
