What is a website speed test and why is it important?

A website speed test is a diagnostic tool that analyzes how quickly your website loads and identifies performance bottlenecks. Website speed is crucial for user experience, SEO rankings, and conversion rates. Google uses page speed as a ranking factor, and studies show that 53% of mobile users abandon sites that take longer than 3 seconds to load. Our speed test checks server response times, compression, caching, and protocol support to give you a complete performance picture.

How do I test my website performance for free?

Testing your website performance is simple and free with our tool. Just enter your website URL in the input field and click "Analyze." Within seconds, you'll receive a comprehensive performance report covering HTTP protocols, compression, caching headers, security configurations, and Time to First Byte (TTFB). No registration, no account, no limits - test as many websites as you need.

What is a good website speed score?

A good website speed score depends on the metrics being measured. For our tool, an A or A+ grade (90-100 score) indicates excellent server configuration with modern protocols and proper optimization. For Time to First Byte (TTFB), aim for under 200ms. For total page load time, under 2 seconds is considered good, while under 1 second is excellent. Google's Core Web Vitals recommend LCP under 2.5s, FID under 100ms, and CLS under 0.1 for a good user experience.

How can I improve my website loading time?

To improve website loading time, focus on these key areas: Enable Brotli or GZIP compression to reduce file sizes by 60-80%. Implement HTTP/2 or HTTP/3 for faster multiplexed connections. Set proper caching headers to reduce repeat requests. Optimize images with next-gen formats like WebP. Use a CDN to reduce geographic latency. Enable Keep-Alive connections to reduce TCP overhead. Our speed test identifies which of these optimizations are missing and provides specific server configuration directives to implement them.

What is Time to First Byte (TTFB) and how do I improve it?

Time to First Byte (TTFB) measures the time between a browser requesting a page and receiving the first byte of data from the server. A good TTFB is under 200ms, acceptable is 200-500ms, and anything over 600ms needs improvement. To improve TTFB: Use a faster hosting provider, implement server-side caching (like Varnish or Redis), optimize database queries, use PHP OPcache, reduce WordPress plugins, and consider a CDN. TTFB is a Core Web Vitals component that directly impacts SEO rankings.

What's the difference between Brotli and GZIP compression?

Both Brotli and GZIP are compression algorithms that reduce file sizes for faster transfers. Brotli, developed by Google, typically achieves 15-25% better compression ratios than GZIP, especially for text content. Brotli uses a predefined dictionary of common web patterns, making it more efficient for HTML, CSS, and JavaScript. However, Brotli requires more CPU for compression (but not decompression). Most modern browsers support Brotli, but GZIP should remain as a fallback. Our tool tests for both and helps you configure your server to use them optimally.

How does HTTP/3 improve website performance?

HTTP/3 uses QUIC (Quick UDP Internet Connections) instead of TCP, providing several performance benefits. It eliminates head-of-line blocking at the transport layer, reduces connection establishment time with 0-RTT handshakes, handles network changes (like switching from WiFi to mobile) seamlessly, and includes encryption by default. Real-world tests show HTTP/3 can reduce page load times by 10-30%, with even greater improvements on high-latency or unreliable networks. Our speed test checks if your site supports HTTP/3 and provides configuration guidance.

How accurate is this website speed test compared to Google PageSpeed?

Our speed test focuses on different aspects than Google PageSpeed Insights. While PageSpeed emphasizes frontend metrics and Core Web Vitals (LCP, FID, CLS), our tool specializes in server-side configuration: HTTP protocols, compression, caching headers, and security. Both tools are accurate for their respective purposes and complement each other. Use PageSpeed for frontend optimization guidance and our tool for server configuration and backend performance. Together, they provide a complete picture of your website's performance.
