This tool is used for checking the speed of the page. This tool checks how fast a website is loading. If your website consists of many embedded images and videos then it will take more time to load. If you have a very low pagespeed insight score then this will result in lowering the rank of your website in search engine results as google considers the page load time as an important SEO factor. This tool is very simple to use. Just enter the URL in the textbox and hit enter and you will get the results within seconds.
