Why Core Web Vitals are important?

By Mahmood Chowdhury

Core web vitals are a set of metrics that measure the performance and user experience of a website. These metrics include load time, speed, and responsiveness, all of which are critical for ensuring that a website is fast and easy to use for visitors.

There are several reasons why core web vitals are important. First, they help to ensure that a website is fast and responsive, which can improve the user experience and increase the likelihood that visitors will stay on the site and interact with it. This can lead to higher engagement and conversion rates, as well as improved search engine rankings.

Second, core web vitals can help to identify and fix performance issues on a website. By monitoring these metrics, website owners and developers can pinpoint areas that need improvement and make the necessary changes to optimize the site.

Third, core web vitals are increasingly becoming a factor in search engine rankings. Google has announced that it will use these metrics as a ranking signal in its search algorithm, which means that websites that score well on core web vitals will be more likely to appear at the top of search results.

in addition to the importance of Core Web Vitals, it’s also important to understand what a good score is for these metrics.

The three main core web vitals are:

  1. Largest Contentful Paint (LCP): Measures loading performance. A good score for LCP is 2.5 seconds or faster.
  2. First Input Delay (FID): Measures interactivity. A good score for FID is 100 milliseconds or less.
  3. Cumulative Layout Shift (CLS): Measures visual stability. A good score for CLS is 0.1 or less.

It’s worth noting that these thresholds are subject to change as the web evolves, but these are the current recommended values according to google.

Additionally, Google provides a tool called PageSpeed Insights (PSI) which can be used to analyze the performance of a webpage and it provides a score based on the Core Web Vitals and other performance metrics, it also gives you suggestions on how to improve the score.

It’s important to note that achieving a perfect score on all of these metrics is not always possible, as it depends on the nature of the website and the types of pages it serves. However, by focusing on these metrics and making improvements where necessary, website owners and developers can ensure that their site is fast, responsive, and easy to use for visitors.

In conclusion, core web vitals are important because they can improve the user experience, help to identify and fix performance issues, and play an increasingly important role in search engine rankings. By focusing on these metrics and making improvements where necessary, website owners and developers can ensure that their site is fast, responsive, and easy to use for visitors.
