Fast-loading websites improve user retention, decrease bounce rates, and rank higher in search engine results. Even minor delays can lead to lost traffic and reduced conversions.
How does this browser-based speed test work?
The tool requests the target URL directly from your browser environment and measures the duration from initial request to full asset loading. This reflects how quickly the page loads from your current network connection.
Is the Website Speed Test completely free?
Yes, the tool is completely free to use. You can run multiple speed tests without signing up or providing any personal information.
What factors affect page load speed?
Key factors include server response time, unoptimized images, excessive JavaScript, uncompressed assets, and network latency.
Can I test websites behind authentication or paywalls?
The tool is designed to test publicly accessible URLs. Pages requiring login credentials or restricted by private firewalls cannot be evaluated accurately.
