What is a Website Speed Test?
A website speed test is a performance analysis tool that measures how fast your website loads and performs. It analyzes key performance metrics including Core Web Vitals (LCP, FID, CLS), page load times, render-blocking resources, and provides a comprehensive performance score from 0-100. Website speed tests are essential for SEO optimization, user experience improvement, and identifying performance bottlenecks that may be slowing down your website.
According to Google Web.dev, website speed is a critical ranking factor for search engines. Google uses Core Web Vitals as ranking signals, meaning faster websites rank higher in search results. A website speed test helps you understand your website's performance, identify optimization opportunities, and ensure your site meets Google's performance thresholds for optimal SEO rankings.
Our website speed test tool uses Google PageSpeed Insights API to analyze your website's performance. This provides accurate, real-world performance metrics based on actual user experience data. The tool tests both mobile and desktop performance, giving you comprehensive insights into how your website performs across different devices and network conditions. Mobile testing is particularly important as Google uses mobile-first indexing, meaning your mobile performance directly impacts your search rankings.
📱Mobile Speed Test
Simulates how your website performs on mobile devices with slower CPU and mobile network conditions. Mobile tests are critical for SEO as Google uses mobile-first indexing and mobile performance as ranking factors.

Website speed tests serve many purposes: optimizing website performance for better user experience, improving SEO rankings through Core Web Vitals optimization, identifying performance bottlenecks and slow-loading resources, monitoring website performance over time, comparing performance before and after optimizations, and ensuring your website meets Google's performance thresholds. Whether you're optimizing a new website or monitoring an existing one, regular speed testing helps maintain optimal performance and search rankings.
Understanding Core Web Vitals
Core Web Vitals are three key metrics that Google uses to measure website user experience. These metrics are ranking factors for Google search results and directly impact your SEO performance.
⚡Largest Contentful Paint (LCP)
Measures loading performance. LCP marks the point when the largest content element (image, video, or text block) becomes visible in the viewport.
Google Threshold
Good: < 2.5 seconds
Needs improvement: 2.5-4.0s
Poor: > 4.0s
🎯First Input Delay (FID)
Measures interactivity. FID measures the time from when a user first interacts with your page (clicks, taps, key presses) to when the browser responds.
Google Threshold
Good: < 100 milliseconds
Needs improvement: 100-300ms
Poor: > 300ms
📐Cumulative Layout Shift (CLS)
Measures visual stability. CLS quantifies how much visible content shifts during page load, which can be frustrating for users.
Google Threshold
Good: < 0.1
Needs improvement: 0.1-0.25
Poor: > 0.25
SEO Impact
According to Google's Core Web Vitals documentation, these metrics are ranking factors for search results. Websites that meet the "Good" thresholds for all three Core Web Vitals are more likely to rank higher in Google search results. Regular speed testing helps ensure your website maintains optimal Core Web Vitals scores.
