What are Google Core Web Vitals?

Google Core Web Vitals are a set of performance metrics that give the website owners an insight into how well their website is doing. It mostly considers how much time your website takes to load or how quickly it provides the users with the content they are looking for.

The truth is nobody likes a slow-loading website that turns off great user experience. To help the WordPress Website owners, Google Core Web Vitals currently comprises three metrics that give an overall view of a website’s performance.

Three metrics of Google Core Web Vitals

Largest Contentful Paint (LCP): This metric measures the loading of the website page. It simply means how much time it takes for the main content of the website page to load. Your LCP should be under 2.5 seconds. Loading time beyond that is considered poor.

First Input Delay (FID): This metric measures the interactivity of the website page. It simply means how much time it takes for your website page to become interactive for the user. The time between the user clicks and when the website browser responds is called First Input Delay. It should be under 100 ms.

Cumulative Layout Shift (CLS): This metric measures the visual stability of the website page. It means how much your content visually shifts while loading. Your content layout shouldn’t shift except when caused by user interaction but if it does, it is known as Cumulative Layout Shift. To provide an excellent visitor experience, CLS should always be under 0.1.

How to Improve your Core Web Vitals on WordPress

  • Optimize your images : Everyone looks forward to a visually appealing sight when it comes to consuming content online but more often than not it becomes frustrating when it takes a lot of time to load. This destroys the user-friendly experience of the website which is a threat to the website’s success. To avoid this, the website owners should keep a check on the images displayed alongside the content.

You can also optimize your images keeping in mind the size, dimension, and servers that decide the loading time of a website. Avoid using images that are too heavy and too large. You can even avoid using sliders and carousels on your web page as they take more time to load.

  • Optimize your code: Unnecessary loading of codes like HTML, Javascript, or CSS before your website’s main content will increase the loading time which doesn’t count as a feasible experience. Having said that, you can choose to optimize these codes by hiring a freelance WordPress developer or opting for Autoptimize which avoids bloated codes. This keeps the website performance in check.
  • Speed up your server: If your server responds quickly to your requests, it directly improves the performance of your website. Therefore, optimizing your server for a greater speed should be on your priority list. This includes upgrading your hosting plan with new hardware, if you find the previous one lacking. In addition to this, using a content delivery network for reducing the loading time if you have a global audience can also work wonders in improving the Google Core Web Vitals.
  • Use only essential plugins: WordPress websites use many plugins. The majority of these plugins create unnecessary codes that are harmful for your website’s performance. Therefore, it is advised to use lightweight plugins only on dedicated pages to avoid code clutters and improve the website’s performance.
  • Optimize web fonts: If you are committed to using Google fonts, make sure to use Autoptimize to handle fonts to avoid any loading font issues such as a flash of invisible text or flash of unstyled text. You can even try preloading your Google fonts to prevent the flash of such texts that disrupts the Cumulative Layout Shift of your website.
  • Ad placement: Ads create a lot of problems when placed incorrectly on the website. They might take a lot of space and push important content down creating a poor user experience. To avoid this, you can create a balanced placement of ads on the website. This avoids unnecessary clutters on your website.
  • Improve loading of third-party scripts: If your website relies on third-party scripts like ad scripts that load slowly, it may impact your site negatively. You may have to experiment with hosting the script yourself or controlling the loading process to make the website load faster. You can even opt for options that are a bit more optimized. This way you keep a check on your website’s accomplishments.
