Website Speed Checker

This speed check measures what can be measured precisely from a server: response time, the weight of the page and each resource, compression, caching and scripts that block rendering. When configured, Core Web Vitals come from Google PageSpeed Insights.

Checks performed

What slows most websites down

In order of frequency: oversized images, slow hosting without page cache, too many third-party scripts (chat widgets, trackers), and missing compression.

Lab data vs real users

A single test is a snapshot from one location. Core Web Vitals field data (from real Chrome users) is the reference Google uses for ranking.

FAQ

What is a good server response time?
