What are Google Core Web Vitals?

In the ever-evolving world of search engine optimization, user experience (UX) has become a critical factor for website success. Search engines like Google, recognizing the importance of UX, have incorporated it into their ranking algorithms. This means a website that loads quickly, is interactive, and is visually stable is more likely to rank higher in search engine results pages (SERPs) and attract more traffic, engagement, and conversions.

Core Web Vitals are a set of standardized metrics from Google that help developers understand how users experience a web page. These vitals are an essential part of Google's “page experience” score, which is a mix of factors that Google considers important for user experience, including HTTPS, mobile-friendliness, lack of interstitial pop-ups, safe browsing, and more.

These metrics were introduced in March 2020 and have since become critical to all web experiences. They measure the user experience needs that all websites should strive to meet, including loading, interactivity, and visual stability.

Core Web Vitals provide a granular technical view of webpage performance and offer a host of information that developers can use to provide a better user experience. Google has emphasized the importance of Core Web Vitals over other metrics, as they are critical to all web experiences and are now considered a ranking factor for search results.

Currently, the Core Web Vitals consist of three metrics, namely Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS).

1. Largest Contentful Paint (LCP)

LCP measures the loading performance of a web page, specifically the time it takes for the largest piece of content, such as an image or text block, to become visible to the user. LCP is a crucial metric as it directly influences the user's perception of a page's loading speed and overall user experience.

Optimizing Largest Contentful Paint LCP is essential for providing a seamless user experience and improving search engine rankings. Studies have shown that when a site meets the Core Web Vitals thresholds, users are 24% less likely to abandon page load, highlighting the significant impact of LCP on user engagement. Additionally, with each 100ms reduction in LCP, conversion rates can increase by up to 8%, emphasizing the direct link between LCP and business metrics.

Ideally, LCP should occur within 2.5 seconds for an optimal user experience. According to Google, websites with an LCP of more than 4 seconds are considered poor.

2. First Input Delay (FID)

FID measures the interactivity of a web page, assessing the responsiveness of the page to user interactions. A low FID indicates that the page reacts promptly to user actions, enhancing the overall UX. A good FID score is below 100 milliseconds.

Optimizing Input Delay FID is significant for improving search engine rankings and user engagement. According to a study, when a site meets the Core Web Vitals thresholds, users are 24% less likely to abandon page load, highlighting the significant impact of FID on user engagement. Additionally, with each 100ms reduction in FID, conversion rates can increase by up to 8%, emphasizing the direct link between FID and business metrics.

In May 2023, it was announced that FID would be replaced by Interaction to Next Paint (INP) by March 2024.

3. Cumulative Layout Shift (CLS)

Cumulative Layout Shift (CLS) is a user-centric metric that measures the visual stability of a web page by quantifying how often users experience unexpected layout shifts. It calculates a score based on how much of the page is unexpectedly moving about, and how often. These shifts of content can be very annoying, making users lose their place in an article they’ve started reading or, worse still, making them click on the wrong button.

A low Cumulative Layout Shift CLS score ensures that the page remains stable and predictable, preventing frustrating disruptions to the user's viewing experience. A good CLS score is anything below 0.1, while anything above 0.25 is considered poor.

How Importance Are Google Core Web Vitals?

Each of these metrics plays a vital role in measuring different aspects of the user experience. For instance, LCP focuses on the page's loading speed, FID evaluates its interactivity, and CLS assesses its visual stability.

These metrics are particularly important because they are based on actual field data, providing a realistic reflection of the user experience. By optimizing these metrics, website owners can create a positive user experience that encourages users to stay longer, engage with content, and return to the site in the future.

For example, a case study by Cloudinary found that optimizing LCP, FID, and CLS improved the conversion rate of a website by 33%. In another study, Backlinko found that websites with poor Google Core Web Vitals experienced a 13% decline in organic traffic.

Google also reports that pages with good Core Web Vitals have a 70% chance of having lower bounce rates and a 24% higher chance of conversions. Also, with each 100ms reduction in Largest Contentful Paint (LCP), conversion rates can increase by up to 8%.

In one of the case studies reported by Google, reducing Cumulative Layout Shift (CLS) by 0.2 led Yahoo! JAPAN to a 15% increase in page views per session, 13% longer session durations, and a 1.72 percentage point decrease in bounce rate.

How CLS optimizations increased Yahoo! JAPAN News's page views per session by 15%

These statistics highlight the direct impact of Core Web Vitals on user engagement and business metrics, emphasizing the importance of optimizing these metrics for a better user experience and improved performance.

Google plans to make page experience an official ranking factor, and Core Web Vitals will be a significant part of that score.

How to Optimize Google Core Web Vitals

How to Optimize Google Core Web Vitals

To optimize Google Core Web Vitals, it's essential to focus on specific strategies for each vital metric. Here are some techniques for improving each Core Web Vital:

1. Largest Contentful Paint (LCP)

  • Optimize images and videos: Compress and resize images and videos to reduce their file size and improve loading times. Use modern image formats such as WebP to take advantage of better compression and quality.
  • Prioritize above-the-fold content: Ensure that the most important content loads quickly to provide users with a positive initial experience. Lazy loading techniques can be used to defer the loading of non-essential below-the-fold content.
  • Leveraging Content Delivery Networks (CDNs): Distribute content across multiple servers globally, minimizing latency and ensuring rapid delivery to users worldwide.
  • Minification: Remove unnecessary whitespace and comments from CSS and JavaScript files, reducing file sizes and improving page load times.
  • Server-Side Rendering (SSR): Generate HTML content on the server rather than relying solely on client-side rendering, reducing the load on the browser and enhancing LCP.
  • Optimizing Third-Party Scripts: Evaluate and eliminate unnecessary third-party scripts, as they can slow down page loading and introduce CLS issues.

2. First Input Delay (FID)

  • Minimize JavaScript execution time: Reduce the amount of JavaScript code and optimize its execution to minimize the time it takes for a page to become interactive.
  • Optimize third-party scripts: Limit the number of third-party scripts and ensure they are optimized for performance to prevent delays in page interactivity.
  • Use browser caching: Leverage browser caching to store frequently accessed resources, reducing the time it takes to load them and improving page interactivity.
  • Optimize event handlers: Use passive event listeners to reduce the time taken by the page to respond to user interactions.
  • Use a content delivery network (CDN): A CDN can help distribute the content of your website across multiple servers, reducing the time it takes to load the page.
  • Prioritize visible content: Load the most important content of the page first to provide a good user experience even if the rest of the page is still loading.
  • Reduce server response time: Optimize your server configuration and hosting environment to reduce the time it takes to respond to requests.

3. Cumulative Layout Shift (CLS)

  • Set dimensions for media: Reserve space for images, videos, and other media on the page to prevent layout shifts when they load.
  • Preload content: Load content that is likely to appear on the page before it is visible to the user to prevent layout shifts.
  • Avoid inserting content above existing content: Inserting content above existing content can cause layout shifts. Instead, insert content below existing content or reserve space for it.
  • Use animations and transitions carefully: Animations and transitions can cause layout shifts. Use them sparingly and carefully.
  • Optimize font and CSS loading: Ensure that fonts and CSS files are properly loaded and configured to prevent layout shifts during page loading.
  • Avoid heavy images and ads: Large images or ads that push content around can negatively impact CLS. Minimize the use of heavy media elements and consider using lazy loading techniques to defer their loading until necessary.
  • Use modern web technologies: Leverage modern web technologies such as CSS Grid and Flexbox to work on the layout stability and prevent unexpected shifts.
