Understanding Core Web Vitals is crucial for any website owner. They are a set of real-world user experience metrics that Google considers significant in a webpage’s overall user experience. Let’s jump right into it.
Core Web Vitals are comprised of three primary metrics: Largest Contentful Paint, Cumulative Layout Shift, and Interaction to Next Paint, which supersedes the erstwhile First Input Delay, commonly referred to as FID. Additionally, there are other significant metrics like Time to First Byte and First Contentful Paint.
“Only 12% of mobile results and 13% of desktop results passed the CWV assessment, meaning they were considered good in all three metrics.”
Largest Contentful Paint loads that it determines when the main content of a page is ready for the viewer. It’s critical as it impacts how users perceive the speed of your page. Ideally, your LCP should happen within 2.5 seconds to keep users happy.
Why LCP matters
Interpreting LCP scores
Cumulative Layout Shift measures the visual stability of your website — how much the content moves or shifts as a page loads. Have you ever been startled by a button moving just as you’re about to click it? That’s layout shift in action. These movements can frustrate visitors, leading to a poor user experience.
To reduce user irritation, it’s crucial to keep your page’s CLS score as low as possible, ideally under 0.1, signifying minimal unexpected content movement.
Remember, when content is stable, visitors can navigate your site with confidence and ease — that’s the ultimate goal!
Why CLS matters
Interpreting CLS scores
Interaction to Next Paint is a fresh metric targeting the measure of responsiveness when a user first interacts with your website. Think of it as evaluating the time between a user’s action, like a click or a tap, and when they see the result of that action on your screen.
For a seamless user experience, you want to make sure your site performs well not just visually, but also in terms of interaction. User expectations are high, and even small delays can be noticeable.
Keep an eye on INP, as it’s a burgeoning aspect of user experience that could become increasingly important in the years ahead!
Why INP matters
Interpreting INP scores
Time to First Byte is a critical metric that measures the duration from a user’s request to the moment the browser receives the first byte of your web page. It’s an under-the-hood look at the initial stages of the loading experience, denoting the responsiveness of your web server or hosting provider.
The purpose is to have your TTFB under 200 milliseconds, as it can greatly enhance the perceived performance of your site. Always keep in mind, the quicker your server responds, the sooner your content starts to emerge, and the happier your users are likely to be.
By optimizing your TTFB, you’re setting a solid foundation for your website’s overall speed and establishing good first impressions with your visitors.
Why TTFB matters
Interpreting TTFB scores
First Contentful Paint is a fundamental metric tracking the time from when the page begins to load to when any part of the page’s content is first displayed on the screen. It includes text, images, or even SVGs. A swift FCP is reassuring to users as it gives a visual cue that the page is loading.
The earlier the FCP occurs, the faster a user feels the site is, positively influencing their perception of your website’s performance. Delayed FCP may lead to impatience and potentially increase bounce rates as visitors might believe that the page is stuck or broken.
A good FCP time would be 1.8 seconds or less, which falls into the “fast” category, conveying to users that your site is responsive and they can start interacting with it almost immediately.
Understanding and optimizing your FCP score is vital for holding your visitor’s attention from the moment they land on your page. That first impression counts!
Why FCP matters

Core Web Vitals are critical because they embody a group of particular elements that Google deems significant in evaluating a webpage’s overall user experience. These indicators—Largest Contentful Paint, Interaction to Next Paint, and Cumulative Layout Shift—measure the user’s practical experience regarding loading efficiency, responsiveness, and visual constancy. Achieving high Web Vitals scores is essential to guarantee a seamless, swift, and engaging website experience, which is pivotal in the modern, competitive digital environment.
Having strong Core Web Vitals is essential for search engine optimization, as Google has incorporated these indicators into its ranking formula. Sites with superior scores tend to appear higher in search engine results pages (SERPs), resulting in more visibility and natural traffic. In essence, by enhancing these vitals, site proprietors can boost their website’s visibility and potentially decrease the abandonment rates that come from subpar user experiences.
Making Core Web Vitals a priority can contribute to increased conversion rates. A site that loads rapidly, reacts without delay to user inputs, and sustains a consistent layout is more likely to hold onto users and instill trust, which has a direct effect on its commercial prosperity. Therefore, monitoring these metrics has become imperative.
In June 2021, Google released a pivotal algorithm update, integrating Core Web Vitals as a ranking factor to emphasize the importance of page experience. This marked a significant shift in SEO, as it highlighted the value of the user’s experience on a website beyond the traditional focus on content quality and keyword relevance. With this update, Google made it clear that pages offering a superior user experience would have an edge in search engine rankings.
The update meant that webmasters and SEOs had to ensure that websites were optimized not just for content but also for these new metrics to maintain or improve search engine visibility. Websites with long-loading visuals or unstable interfaces risked falling lower on SERPs, offering a competitive advantage to sites with better-performing metrics.
Google is poised to launch its most significant revision to Core Web Vitals since their inception in 2020. By March 2024, Google intends to substitute the First Input Delay (FID) metric with the Interaction to Next Paint (INP). This modification will have implications for website proprietors globally, and it is advised that they undertake appropriate measures to enhance their INP metrics.
While it’s key to prepare for the Core Web Vitals update in March 2024, always remember that the ultimate goal of these metrics is to ensure a delightful user experience which fosters loyalty and benefits your online presence in the long term.
Google Search Console is a pivotal tool for webmasters, SEO experts, and site owners to measure their website’s search traffic and performance. It’s the go-to place to understand how Google views your site and to optimize for better search presence.
