What is GTmetrix?
GTmetrix is a website performance testing tool designed to monitor page performance and provide detailed reports on the performance of any website.
GTmetrix keeps tracks of page metrics such as page scores, page speed, number of requests, and more with in-depth visualizations and scheduled monitoring. GTmetrix can easily analyze the loading times of any web page with access to 65 servers in 22 different locations.
GTmetrix utilizes Google Lighthouse to receive accurate page insights into different performance metrics. The built-in report page summarizes performance data based on performance indicators such as contentful paint, total blocking time, and cumulative layout shift. Users can also test mobile web pages on real Android devices or simulated devices. GTmetrix can easily simulate performance on 20+ different mobile devices.
