Lets face it, load speed (or the lack of it) can be one of the most frustrating things about using some sites on the web. More often than not these days, people are searching and surfing on mobile too, partly because time and convenience are usually of the essence.
Thats why Google is pushing LCP as one of its core metrics for measuring site performance. It tracks how long it takes for the largest content element of the visible part of the page to appear to the user. Anything under 2.5 seconds is considered ‘Good, anything between 2.5 and 4 seconds ‘Needs Improvement and anything that takes longer than 4 seconds is deemed ‘Poor.
An unsatisfactory score can be triggered by many things, including slow server response time, JavaScript and CSS that blocks rendering, slow loading of resources like images and video files and client-side rendering.
Anything that takes up a great deal of space will be a red flag when it comes to what is presented to the user, but these issues can be fixed
by optimizing the server, adopting a local image CDN to serve global users faster, caching assets and serving HTML pages cache-first and minifying CSS and JavaScript.
