What’s A Good Core Web Vitals Score?

Core Web Vitals are a crucial set of metrics that have been introduced by Google to help website owners understand and improve the user experience of their websites. These metrics provide a holistic view of a website’s performance, taking into account various aspects that contribute to the overall user experience.

Understanding Core Web Vitals

Core Web Vitals provide a comprehensive view of a website’s performance, focusing on three key areas: loading, interactivity, and visual stability. By monitoring and optimising these metrics, website owners can ensure that their sites provide a seamless and engaging experience for their users.

By monitoring and optimising these three areas, website owners can gain valuable insights into how their site performs from a user’s perspective. This allows them to identify areas that need improvement and take proactive steps to enhance the overall user experience. Ultimately, optimising Core Web Vitals can lead to higher user engagement, better conversion rates, and improved search engine rankings.

The Three Core Web Vitals Metrics

Core Web Vitals consists of three main metrics: Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS). Each metric measures a different aspect of a website’s performance, and understanding them is crucial to improving your Core Web Vitals score.

Each of these metrics focuses on a specific aspect of website performance and provides valuable insights into the user experience.

Largest Contentful Paint (LCP) measures the time it takes for the largest content element on a webpage to become visible. This could be an image, a video, or a text block. LCP is a critical metric because it directly impacts the user’s perception of a website’s loading speed. A faster LCP means that users can start interacting with the content more quickly, leading to a better overall experience.

First Input Delay (FID) measures the time it takes for a website to respond to a user’s first interaction, such as clicking a button or tapping a link. This metric is important because it reflects the responsiveness and interactivity of a website. A lower FID indicates that the website is more responsive and provides a smoother user experience.

Cumulative Layout Shift (CLS) measures the visual stability of a website by quantifying the amount of unexpected layout shifts that occur during the lifespan of a webpage. Unexpected layout shifts can be frustrating for users, as they can cause them to accidentally click on the wrong link or lose their place on the page. A lower CLS score indicates that the website has better visual stability and provides a more consistent and predictable user experience.

By understanding these three metrics and how they contribute to the overall Core Web Vitals score, website owners can better identify areas that need improvement and develop targeted strategies to optimise their site’s performance.

Interpreting Core Web Vitals Scores

Core Web Vitals scores are classified into three categories: good, needs improvement, and poor. Understanding what these categories mean and how to interpret your scores is essential for optimising your website’s performance and user experience.

To interpret Core Web Vitals scores effectively, it’s important to understand the different categories that Google uses to classify them. These categories are:

Good: A “good” score indicates that the website’s performance is meeting the recommended thresholds for Core Web Vitals. Specifically, a good score means that the website has an LCP of 2.5 seconds or less, an FID of 100 milliseconds or less, and a CLS of 0.1 or less.

Needs Improvement: A “needs improvement” score suggests that the website’s performance falls within the average range but could still benefit from optimisation. This category applies when the website has an LCP between 2.5 and 4 seconds, an FID between 100 and 300 milliseconds, or a CLS between 0.1 and 0.25.

Poor: A “poor” score indicates that the website’s performance is below the recommended thresholds and requires immediate attention. This category is assigned when the website has an LCP of more than 4 seconds, an FID of more than 300 milliseconds, or a CLS of more than 0.25.

By understanding what each of these categories means, website owners can better interpret their Core Web Vitals scores and take appropriate action. For example, if a website has a “poor” score for LCP, the owner should prioritise optimising the site’s loading speed to improve the user experience. If a website has a “needs improvement” score for FID, the owner can focus on enhancing the site’s interactivity and responsiveness.

It’s important to note that the interpretation of Core Web Vitals scores should be based on a combination of all three metrics, as each one contributes to the overall user experience. Website owners should strive to achieve “good” scores across all three metrics to provide the best possible experience for their users.

Identifying Issues And Optimising Core Web Vitals

Once you’ve identified areas that need improvement, it’s time to start optimising your website to achieve better Core Web Vitals scores. There are various techniques and strategies you can employ to address issues related to loading, interactivity, and visual stability.

After interpreting your Core Web Vitals scores and identifying areas that need improvement, the next step is to start optimising your website to address these issues. There are various techniques and strategies that website owners can employ to improve their Core Web Vitals scores, depending on the specific areas that require attention.

For optimising loading performance (LCP)

• Implement lazy loading for images and other media to defer the loading of non-critical resources until they are needed.
• Optimise images by compressing them and serving them in the appropriate format and size.
• Leverage browser caching to reduce the amount of data that needs to be fetched on subsequent page visits.
• Minify and compress CSS, JavaScript, and HTML files to reduce their file size and improve loading times.
• Prioritise critical resources and delay the loading of non-essential content until after the initial render.

For improving interactivity (FID)

• Minimise the use of heavy JavaScript and third-party scripts that can block the main thread.
• Break up long tasks into smaller, asynchronous chunks to avoid blocking the main thread.
• Implement code-splitting to load only the necessary code for each page, reducing the amount of JavaScript that needs to be parsed and executed.
• Optimise the use of event listeners and remove unnecessary ones to reduce the workload on the main thread.

For enhancing visual stability (CLS)

• Reserve space for dynamic content that will be loaded later, such as images, videos, or advertisements.
• Avoid inserting content above existing elements, which can cause unexpected layout shifts.
• Use appropriate aspect ratios and size attributes for media elements to prevent layout shifts when they are loaded.
• Utilise CSS properties like transform and opacity instead of width, height, or left/right to animate elements, as these properties are less likely to trigger layout shifts.

By implementing these techniques and strategies, website owners can address specific issues related to loading, interactivity, and visual stability, and ultimately improve their Core Web Vitals scores.

The Importance Of Monitoring And Continuous Improvement

Optimising Core Web Vitals is not a one-and-done task; it’s a continuous process that requires vigilant monitoring and a commitment to ongoing improvement. As websites grow and change over time, with new content being added, features being updated, and technologies evolving, it’s crucial to keep a close eye on your Core Web Vitals scores to ensure that the user experience remains consistently high-quality.

Even after achieving good scores, it’s essential to monitor your website’s performance regularly to identify any changes or regressions that may occur. This could be due to factors such as new code being added, changes in third-party libraries or services, or updates to the underlying technologies used by your website.

Regularly monitoring your Core Web Vitals scores will allow you to detect any performance issues or drops in user experience quickly. This can be achieved by setting up alerts or notifications to inform you when your scores fall below the recommended thresholds. Additionally, conducting regular audits and running Core Web Vitals reports can help you stay on top of your website’s performance and identify areas that may require further optimisation.

It’s also important to adopt a mindset of continuous improvement when it comes to Core Web Vitals. As new techniques, best practices, and technologies emerge, it’s crucial to stay up-to-date and incorporate them into your optimisation efforts. This may involve refactoring existing code, adopting new frameworks or libraries, or implementing new optimisation strategies.

By embracing a proactive approach to monitoring and continuous improvement, website owners can ensure that their sites maintain good Core Web Vitals scores over time, providing a consistently excellent user experience that keeps users engaged and coming back.
