Google wants to know if your company provides an excellent page experience to users. They aim to highlight and support enterprises that strive to achieve one or two aspects of a decent page. They employ metrics like Core Web Vitals to help identify top performers. 

An Introduction to Core Web Vitals

Core Web Vitals are a set of metrics that measure your site’s user experience. Investing in your core web vitals has various benefits, including an impact on Google SEO ranking, conversion rate, and user retention. 

Let’s dive a little deeper into each to understand why this matters. 

Core web vitals  impact on Google SEO ranking

Google SEO rankings: Studies show that only 0.44% of Google search users visit second-page results. Where you land on a search page matters. 

SEO ranking reflects how well your website satisfies users' interests and needs. For instance, a good Google SEO ranking makes your website more visible and facilitates traffic, which means more opportunities to convert prospects into customers. 

Conversion rate: A conversion rate is the percentage of ad interactions that lead to a conversion. Suppose your website has 1,000 user interactions and 50 conversions (making a purchase, signing up for a newsletter, or contacting your business). This means that your conversion rate is 5%. 

This is important because you’ll watch how they shift as you tweak campaigns; they will go up and/or down. It helps you measure the impact of your ad campaigns. Even a subtle jump of 0.5% can impact your business. 

User retention: While some of your campaigns will be focused on new customer acquisition, retaining customers is equally essential to long-term success as it helps maintain a steady customer base.

Because of the elements above, core web vitals influence how visitors perceive your site, so investing in each of the pillars contributing to it is crucial.

What Are the Core Web Vitals Pillars?

Google considers core web vitals essential in a webpage's overall user experience. These metrics measure a site's speed, responsiveness, and visual stability, providing a quantifiable measure of its performance from a user's perspective. The three Core Web Vitals are divided into three areas: Loading, Interactivity, and Visual Stability.


Largest Contentful Paint (LCP): This measures loading performance, precisely the time it takes for your page's most significant content element (like an image or block of text) to become visible within the viewport. 

A good LCP score is 2.5 seconds or faster.


Interactivity refers to how responsive your site is to a user’s input, indicating how quickly it responds to the first interaction. The metric for this is First Input Delay (FID), which measures interactivity and responsiveness. It's when a user first interacts with your page (by clicking a link, tapping a button, etc.) to when the browser can respond to that interaction. 

An excellent threshold to aim for is less than 100 milliseconds.

Visual Stability

Google determines your site’s layout during loading. The metric here is Cumulative Layout Shift (CLS), which quantifies how often users experience unexpected layout shifts. A low CLS is crucial for ensuring a smooth, enjoyable user experience. 

A good score is less than 0.1.

How can you improve each of these? Below are a few ways to go about it.

Actions to Take to Optimize Core Web Vitals

Focusing on the elements below can improve your business's search experience, higher search rankings, and conversion rates. 

Use Reliable Hosting

Use fast and reliable web hosting. Your service response time affects your Largest Contentful Paint (LCP) score. Remember, this measures how quickly your page is loading. Aim to find a hosting that will provide an LCP under 2.5 seconds for a good score.

Optimize Your Images

Images often impact your LCP. Large, unoptimized photos are among the most common causes of poor LCP scores. To improve your LCP, ensure your photos are appropriately sized and compressed. Consider using modern, efficient image formats like WebP, which provides high-quality images at smaller file sizes than traditional formats like JPEG or PNG.

To optimize images, you must do three things: compress, resize, and lazy load.

You can compress with these tools without compromising quality:

Minify and Compress Code

Minification removes all unnecessary characters (whitespace, comments, semicolons) from JavaScript source code without altering functionality. This process optimizes website performance.

Deferring code ensures that the visible elements of a page will load before it runs the script. It instructs the browser to load what the user sees first. 

Compressing files reduces the size.

These steps make your site interactive and responsive. The following tools can help you compress your file sizes to achieve this better:

Conduct Regular Audits

Make it a habit to audit your website's Core Web Vitals regularly. The tools below are recommended for flagging performance. They can provide flag activity in your current performance and offer suggestions for improvement.

Much like all things PPC, keeping healthy Core Web Vitals is not a one-time task. It’s an ongoing process of monitoring and tweaking to changes. 

However, it’s just a hyper-focused approach to user experience and adapting strategies that ensure that digital markers provide value to their visitors.
