Creating a better web experience for mobile users is important, which is why you should consider investing in progressive web apps (PWA), a term Google came up with in 2015.
Page speed is often confused with “site speed,” which is actually the page speed for a sample of page views on a site. Page speed can be described in either “page load time” (the time it takes to fully display the content on a specific page) or “time to first byte” (how long it takes for your browser to receive the first byte of information from the web server).
You can evaluate your page speed with Google’s PageSpeed Insights. PageSpeed Insights Speed Score incorporates data from CrUX (Chrome User Experience Report) and reports on two important speed metrics: First Contentful Paint (FCP) and DOMContentLoaded (DCL).
