Free Website Performance Test
Measure your website's speed
With our Performance Test, analyze in seconds how fast your website loads and where optimization potential exists. Get detailed insights into load times, Core Web Vitals, and server response times. Our tool checks all important performance metrics and shows you exactly which factors slow down your website. A fast website not only improves user experience but is also an important ranking factor for Google. Start your free performance check now and discover opportunities to speed up your site.
Get StartedWhat our Performance Test checks
Core Web Vitals
Measurement of Google's three most important metrics: Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS). These values directly influence your Google ranking and have been considered official ranking factors since 2021.
Load Time Analysis
Detailed measurement of total load time, Time to First Byte (TTFB), First Contentful Paint (FCP), and Time to Interactive (TTI). We show you a waterfall analysis of all loaded resources and identify bottlenecks.
Resource Optimization
Analysis of images, CSS, JavaScript, and fonts. We check for uncompressed files, render-blocking resources, and unused code. Get concrete recommendations for optimizing each resource.
Server Performance
Check of server response time, caching configuration, and CDN usage. We analyze HTTP/2 support, compression (Gzip/Brotli), and the efficiency of your server infrastructure.
Mobile Performance
Separate performance test for mobile devices with simulated 4G connection. Since Google uses mobile-first indexing, mobile speed is crucial for your rankings and user experience on the go.
Comparison & Benchmarks
Compare your performance values with industry averages and competitors. See where you stand and which improvements will have the greatest impact on your user experience.
Frequently Asked Questions
Website speed directly affects your conversion rate, bounce rate, and Google rankings. Studies show that 53% of mobile users leave a page that takes longer than 3 seconds to load. Additionally, Core Web Vitals have been an official Google ranking factor since 2021. A fast website means better user experience, more conversions, and better search engine rankings.
Core Web Vitals are three metrics defined by Google to measure user experience: LCP (Largest Contentful Paint) measures the load time of the largest visible element - target value under 2.5 seconds. FID (First Input Delay) measures response time to first user interaction - target value under 100ms. CLS (Cumulative Layout Shift) measures visual stability - target value under 0.1. All three values factor into your Google ranking.
The most important measures for performance optimization are: compress images and serve them in modern formats (WebP), enable browser caching, minimize and bundle CSS and JavaScript, use a CDN, optimize server response time, eliminate render-blocking resources, and implement lazy loading for images. Our test shows you in priority order which measures will have the greatest effect.
We recommend a performance test after every major change to your website, but at least monthly. Regular tests help detect performance regressions early. Tests are particularly important after website updates, new features, or changes to server infrastructure. With our tool, you can track the development of your performance values over time.
Yes, our performance test analyzes your website for both desktop and mobile devices. The mobile test simulates a typical 4G connection and a mid-range smartphone. Since over 60% of web traffic comes from mobile devices and Google uses mobile-first indexing, mobile performance is particularly important for your online success.
Our tool uses similar metrics to Google PageSpeed Insights but offers additional analyses and more understandable action recommendations. We prioritize optimization suggestions by impact, show industry comparisons, and optionally offer personal consultation for interpreting results. We also store your test results for long-term comparisons.
Yes, server location significantly affects measured load times. Our tool tests from multiple locations worldwide to give a realistic picture of performance for different user groups. For local businesses, we recommend a server location in their region and optionally a CDN for international visitors.
