This parameter reflects the speed of loading. To be convenient in use, the page LCP value should be less than 2.5 seconds after it starts loading. Roughly speaking, this is the speed of the first screen loading, or rather its largest fragment. You can do the following things to improve LCP: Reduce server response time (you can use the Time to First Byte metric to measure it). Use a content delivery network (CDN) - for example Cloudflare. Implement server-side caching. Use rel="preconnect" for early third-party connections.
Reduce JS blocking time and minimize JavaScript. Minimize Industry Email List CSS, delay loading of non-critical CSS, and implement critical CSS. Optimize images and reduce their size. Implement preloading of important resources. Reduce the size of text files. Use server-side rendering or pre-rendering. First Input Delay (FID) and how to improve this parameter This parameter reflects interactivity. To use the site comfortably, the FID value should be less than 100 ms. Roughly speaking, it's the speed of reaction to a button click on the site. How quickly everything starts to change. You can do the following things to improve FID: Break up long tasks into smaller asynchronous tasks. Optimize readiness for interaction (e.g., using progressive code loading). Examine third-party code and prioritize downloads. Use Comlink, Workway, Workerize. Reduce JS execution time (defer unused JS, minimize unused polyfills).
For a page to be usable, the CLS value should be less than 0.1. CLS value is calculated by a special formula that is not very clear to anyone. But the bottom line is simple - the less something is shifted after page load, the lower this indicator will be (ideally - zero). CLS reflects visual stability. You can do the following things to improve CLS: Reserve space for ads, embedded content, and iframes. Don't place ads close to the top of the viewing area. Do not insert new content above existing content. Use font-display attribute, Font Loading API or <link rel="preload"> for basic web fonts.
