Tips to Make Your Magento Store Score More on Core Web Vitals

How to Improve Your Magento Store Score on Core Web Vitals

Every online store is unique offering different products. So, there is no one-size-fits-all for eCommerce stores. Still, there are significant changes that you can make to improve your Magento store score on the Google Core Web Vitals.

Improve Your Ranking with Good LCP

LCP factors time consumed by the largest content element such as text blocks, images, or videos. An ideal LCP score is 2.5 seconds or less.


  • It is good to choose a reliable hosting plan as Time Taken to First Byte (TTFB) is crucial and depicts faster server response time. A shared or slow hosting server requires extensive updating.
  • Optimize images by resizing, compressing, or converting them to a suitable format to improve Magento 2 speed.
  • Merge JavaScript files to keep server requests at the minimum. You can defer the trivial JavaScript for the above-the-fold content.
  • You can even reduce the LCP by preloading important images with JS or CSS. Loading important images faster can significantly enhance the page experience.

    Optimize Your Magento 2 Store for CLS

CLS shows the outcomes of unanticipated page layout shifts without the end-user’s input. A good CLS score of your page should be 0.1, which means your web page is visually stable.

There are two factors to determine your CLS score:

  1. How much the viewport has been affected by the shift, and
  2. How far did the content elements moved during the layout shift to the viewport.


  • You can prevent layout shifts by setting the height and width attributes of each content element.
  • Avoid inserting ads and pop-ups above other content.
  • Magento 2 stores allow you to use placeholders for achieving page layout stability. Placeholders can occupy the accurate dimensions of the images and videos.
  • Use optimized fonts to prevent flashes of invisible text and page layout shifts. You can even use system fonts to eliminate the use of the browser to download the font file when fetching the page.

If you’re an amateur and new to the technicalities of Magento store optimization, then it is wise to hire Magento developers to do it for you.

Increase Magento Store Score at FID

FID computation requires data from end-users who are interacting and engaging with your Magento 2 store. FID estimates the time taken by the browser to process the first user interaction on the web page. Poor FID leads to a higher churn rate and frustrates visitors. You can hire Magento developers to increase your Magento store score at FID.

  • Divide time-consuming tasks into smaller fragments to considerably reduce the overloading of the main thread. This prevents unnecessary delay in the processing of the user’s input. The UI becomes unresponsive when executing a coding block. This can be solved by code splitting.
  • Magento stores are often loaded with various third-party tags and analytics that make the thread busy causing the store to become unresponsive. You can use on-demand loading of these coding, select the content elements that provide greater value to users.
  • Web workers are great for FID optimization as they run in JavaScript on background threads. This does not affect the main thread.
  • Polyfills are JavaScript-based browser fallbacks that let modern functionalities on old browsers, download numerous unnecessary codes. Minimize the number of polyfills and try using only if required.
