  • First Input Delay
  • Cumulative Layout Shift
  • What is a good LCP score?
  • What are the reasons for a poor LCP?
  • How to improve LCP?
Largest Contentful Paint

As per Google’s core algorithm, pages that take about 2.5 seconds or less to load the main content of the is considered as “Good”.

Anything between 2.5 seconds to 4 seconds from the moment of click is classified as “Needs improvement” and more than 4 seconds is considered “Poor”.

Similar to Search Engine Optimization (SEO), which considered page loading speed as one of the factors, LCP is also not a one-time thing. The loading time needs to consistently stay below 2.5 seconds on every click for desired results. This can be achieved only by constant monitoring.

Largest Contentful Paint

The most common reasons behind a poor LCP score are:

  • Longer response time from the server
  • Render blocking resources
  • Slow load times of resources
  • Using Client-side rendering
  • Large size of image
  • Browser loading time
Largest Contentful Paint
  • Improve the efficiency of server-side code and optimize the server.
  • Route using nearby CDN to reduce time waiting for users geographically farther away.
  • Clear away unnecessary third-party scripts.
  • Upgrade web hist for better loading times.
  • Use lazy loading.
  • Minify CSS.
  • Avoid large page elements that may slow down the loading.
  • Optimize and compress text files & images.
  • Preload important resources
  • Serve images in next-gen formats like webP and AVIF
  • What is a good FID score?
  • What are the reasons for a poor FID?
  • How to improve FID?
Largest Contentful Paint

As per Google’s core algorithm, delay less than 100 ms, ie, 0.1 seconds is user friendly and considered as “Good”.

An FID score of anything between 100-300ms, i.e, 0.1 – 0.3 seconds “needs improvement” and FID above 300ms (0.3 seconds) is considered “poor”.

In the majority of cases, the users always feel the system is ready to interact instantly. But, sometimes the users may feel the page is a little irresponsive even though the FID is below 100ms. This is because the browser may take some time to run the tasks related to user input.

Largest Contentful Paint

The common reasons behind a poor FID score are

  • Long Tasks
  • No page interaction readiness
  • Not using a web worker
  • Prolonged JavaScript execution time
Largest Contentful Paint
  • Splitting up long-running code into smaller, asynchronous tasks reduces input delay.
  • Optimize the page for better interaction readiness.
  • Use Web Workers to avoid blocked main thread and run JavaScript on the background thread.
  • Reducing the amount of JavaScript reduces the amount of time spent on executing JavaScript code.
  • Remove any trivial third-party scripts.
  • Use browser cache to load content faster on your page.
  • Load the priority content at the first
  • Eliminate render-blocking resources
  • What is a good CLS score?
  • What are the reasons for a poor CLS?
  • How to improve CLS?
Largest Contentful Paint

Again, as per Google’s core algorithm, a score between 0.1 to 0.25 is considered as “needs improvement” and CLS score above 0.25 is considered “poor”.

To make sure you are reaching your target, it’s advisable that you measure 75% of the page loads on both desktop and mobile.

If the elements move across the layout of the web page while it loads then it’s sure that your CLS score is under hit.

Largest Contentful Paint

The common reasons behind a poor CLS score are

  • Images with improper size attributes.
  • Inserts and resizing of Ads.
  • Embeds and iframes without proper dimensions.
  • Inserting new content over the existing content.
  • Web Fonts triggering FOIT/FOUT ((FOUT – flash of unstyled text & FOIT – flash of invisible text).
Largest Contentful Paint
  • Set dimensions for all forms of multimedia used in your web page (Images, GIFs, videos, infographics, and more).
  • Plan the space for Ad elements and keep it reserved.
  • If adding new UI elements, do it below the fold so that it doesn’t alter the content layout against user expectations.
  • Reserve sufficient space in the viewport for various types of UI affordances in advance.
