What is Website Speed Test?
A website speed test measures how quickly a web server responds to requests and loads page content. Page speed is a Google ranking factor and directly affects user experience — slow pages have higher bounce rates and lower conversions. Our tool measures server response time, page size, and basic performance indicators for any URL.

Frequently Asked Questions
What does server response time mean?
Server response time (also called Time to First Byte or TTFB) is how long it takes the server to start sending a response after receiving a request. A fast response time (under 500ms) is important for user experience and is a Google ranking signal.
What is a good server response time?
Google recommends a TTFB under 200ms as excellent. Under 500ms is good. 500ms to 2 seconds is average and should be investigated. Over 2 seconds is slow and may impact bounce rates and SEO.
How is this different from Google PageSpeed Insights?
This tool measures raw server response time and page weight. Google PageSpeed Insights measures the full rendering experience including Core Web Vitals (LCP, FID, CLS). Use this tool for a quick check and PageSpeed Insights for a full performance audit.
Why might results vary between tests?
Server response time varies due to server load, CDN cache hits, network routing, and geographic distance. This tool averages 3 consecutive requests to reduce variability, but results still depend on real-time network conditions.
What causes slow server response times?
Common causes include unoptimized database queries, no caching layer, too much server-side processing, cheap shared hosting, and not using a CDN. Switching to a CDN and adding server-side caching (Redis, Varnish) typically yields the biggest improvements.
What is a good page load time?
Google recommends a Time to First Byte (TTFB) under 200ms and a total page load time under 3 seconds. For Core Web Vitals, Largest Contentful Paint (LCP) should be under 2.5 seconds.
What causes slow website speed?
Common causes include large unoptimized images, too many HTTP requests, slow server response (poor hosting), unminified JavaScript and CSS, and no content delivery network (CDN).
How does page speed affect SEO?
Google has used page speed as a ranking factor since 2010 for desktop and 2018 for mobile. Since 2021, Core Web Vitals (including LCP, FID, and CLS) are official ranking signals.
