What are Core Web Vitals?

Search Signals for Page Experience

Core web vitals are specific factors that measure how users experience speed, interactivity and page stability. They are a subset of different factors that Google considers crucial when evaluating a web page experience.

In order for SERPs to show web pages that provide users with a good experience, Google announced that, in May 2021, Core Web Vitals are going to take effect in Google ranking. Therefore, the time taken for your website to load and be interactive with a high visual stability will be a great ranking signal.

The 3 Core Web Vitals

  1. Largest Contentful Paint (LCP): the execution time for a page’s largest content to load. It is the time taken from the user’s click to view a page to the appearance of its main content on screen. An ideal LCP measurement is 2.5 seconds or faster.
  2. First Input Delay (FID): the time taken for a page to become interactive with users. It focuses on how long it takes users to be able to take actions on the page in real time (i.e. clicking on a link, filling a form, …etc.). An ideal measurement is less than 100 ms.
  3. Cumulative Layout Shift (CLS): the amount of unexpected layout shift of visual content on a web page. It measures the movement of elements during page load that results in a change of many elements’ positions on the screen where users are interacting. An ideal measurement is less than 0.1.

How to Measure the Core Web Vitals of Your Website?

According to Search Engine Journal, there are 6 tools to measure the core web vitals:

1. Google Search Console: its new core web vitals report shows the performance of pages based on real time data collected from Google Chrome UX report.

How to Improve the Core Web Vitals of Your Website?

  1. Minimize the Largest Contentful Paint (LCP) by using links as preloaders for the main page’s resources that need to be fetched quickly for the user. We can preload different resources (e.g. scripts, styles, videos, images, …etc.)
  2. Improve the First Input Delay (FID) by splitting scripts in small chunks.
  3. Avoid the Cumulative Layout Shifting (CLF) caused by pushing elements and changing their position for other elements to appear on screen, by reserving spaces for images and embedded elements to load in.

Among the several factors used to show web pages and determine their rankings in SERPs like mobile friendliness and website security, Google decided to add the core web vitals as a new ranking signal. It doesn’t mean that improving your core web vitals will surprisingly push you to the top of SERPs but will be one of the greatest factors affecting your position. You still have the chance to show your web pages in higher positions by creating a great user experience.
