Enhance Core Web Vitals- Boost SEO & User Experience

Understanding the Nitty-Gritty of Core Web Vitals and How to Enhance Them

Table of Contents:

One aspect of web design that has been gaining significant traction is the Core Web Vitals - a set of factors that Google deems critical to a webpage’s overall user experience. These values offer insights into a URL’s performance, categorized by status as ‘Good’, ‘Needs Improvement’, or ‘Poor’. The performance output is sourced from actual data garnered from users in the field.

Why Core Web Vitals Matter

Now, why should you care about these Core Web Vitals? Quite simply because Google intends to make ‘page experience’ an official ranking factor. This would be an amalgamation of components considered fundamental for user experience, including mobile-friendliness, HTTPS, absence of interstitial pop-ups, and safe browsing — essentially keeping malicious software off your page.

Core Web Vitals would serve as an essential element in determining this score. Judging by the announcement and name itself, it’s not far-fetched to suggest that core web vitals will constitute the major part of your page experience score.

Improving Your Core Web Vitals

Now, let’s delve into the three Core Web Vitals and discuss how to enhance them:

Largest Contentful Paint (LCP)

Largest Contentful Paint (LCP) is essentially how long a page takes to load from an actual user’s perspective, i.e., from clicking on a link to seeing most of the content on-screen. LCP differs from other pagespeed measurements as it focuses on what really matters: being able to see and interact with your page.

To improve LCP, you can start by eliminating needless third-party scripts that may be slowing down your page load time. Upgrading your web host can also have a significant impact on LCP. Additionally, setting up lazy loading for images and videos can help prioritize the loading of important content first. Removing large page elements and minifying your CSS can further optimize your LCP score.

First Input Delay (FID)

First Input Delay (FID) measures the time it takes for a user to interact with your page once it has achieved Largest Contentful Paint (LCP). FID measures how swiftly users can do something on your page and hence has high importance.

To enhance your site’s FID scores, you should focus on minimizing or deferring JavaScript that may be blocking user interactions. Removing non-essential third-party scripts can also help reduce the delay. Utilizing browser caching can improve the loading speed of your website and contribute to a better FID score.

Cumulative Layout Shift (CLS)

Cumulative Layout Shift (CLS) signifies how stable a page is as it loads. If elements on your page move around while loading, then you have a high CLS, which isn’t good for user experience.

To reduce CLS, there are simple measures you can take. Using set size attribute dimensions for any media, such as images and videos, ensures that the space required for these elements is reserved, preventing layout shifts. Ensuring that ad elements have reserved space can also help minimize unexpected shifts. Additionally, adding new UI elements below the fold can prevent them from pushing existing content around during loading.


In conclusion, understanding Google’s Core Web Vitals is crucial for optimizing your website’s user experience. The better your overall UX is, the higher your page experience scores will be. As you strive towards improving your Core Web Vitals, keep in mind that there are plenty of resources available online, such as Google’s “Basics of UX” guide and the Lighthouse tool in Google Chrome, that can provide valuable insights and guidance.

By focusing on enhancing your Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS), you can significantly improve your website’s performance and provide a better user experience. Remember, while Core Web Vitals are important, they are just one piece of the puzzle. It’s essential to consider other SEO factors and best practices to achieve optimal results.

So, take the time to analyze your Core Web Vitals data, make the necessary optimizations, and watch as your website climbs the ranks in search engine results pages. With effective SEO copywriting and a focus on increasing blog visibility with SEO, you can attract more organic traffic and create a positive user experience for your audience.
