Core Web Vitals Overview
Understanding CWV Metrics
Core Web Vitals (CWV) are crucial elements that contribute to your website’s performance, directly impacting user experience. These metrics focus on user-centric outcomes, reflecting how your website interacts with users. To adequately meet the expectations of both users and search engines, you need to grasp the fundamental CWV metrics: Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), and First Input Delay (FID).
| Metric | Definition | Ideal Threshold |
|---|---|---|
| Largest Contentful Paint (LCP) | Measures loading performance, reflecting how quickly the main content of your page loads. | Less than 2.5 seconds |
| Cumulative Layout Shift (CLS) | Evaluates visual stability, indicating how much your page’s layout shifts during loading. | Less than 0.1 |
| First Input Delay (FID) | Assesses interactivity, determining how quickly a user can interact with your page. | Less than 100 milliseconds |
To meet Google’s performance standards, aim for 75% of page loads for each CWV metric to fall below these recommended thresholds (NitroPack Blog).
Impact on SEO Rankings
The importance of Core Web Vitals for your search engine optimisation (SEO) strategy cannot be overstated. Google considers these metrics as part of its page experience ranking system, aiming to reward sites that provide a fast, smooth, and enjoyable user experience. A better user experience directly correlates with higher search rankings, enhanced user satisfaction, improved engagement, and increased conversion rates.
Research from Deloitte and Google underscores this impact, revealing that even a minor improvement of 0.1 seconds in page speed can lead to significant enhancements across the entire buyer journey, showcasing the profound effects of CWV on your business.

Optimising your CWV can position your website for better rankings and superior user interactions, essential for any New Zealand business owner or marketing professional striving for online success.
Individual CWV Metrics
Understanding CWV metrics is essential for enhancing your SEO strategy. The three key metrics are Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), and First Input Delay (FID). Each metric provides insights into different aspects of user experience, influencing both your ranking on Google and the satisfaction of your visitors.
Largest Contentful Paint (LCP)
Largest Contentful Paint measures the time it takes for the largest visible content block in the user viewport to load. The goal is for LCP to be under 2.5 seconds from when a page starts loading. An LCP of 2.5 to 4 seconds is acceptable but indicates that improvements are needed (Moz).
| LCP Score | User Experience |
|---|---|
| < 2.5 seconds | Good |
| 2.5 – 4 seconds | Needs Improvement |
| > 4 seconds | Poor |
Improving LCP can significantly enhance user engagement and retention on your site. Techniques for LCP optimisation include optimising images, using lazy loading, and improving server response times.
Cumulative Layout Shift (CLS)
Cumulative Layout Shift measures the visual stability of a page by tracking how much visible content shifts during page loading. A good CLS score is less than 0.1, while scores up to 0.25 require improvement (Coralogix).
| CLS Score | User Experience |
|---|---|
| < 0.1 | Good |
| 0.1 – 0.25 | Needs Improvement |
| > 0.25 | Poor |
To improve your CLS score, ensure images and videos have specified dimensions, and avoid inserting content above existing content, which can cause shifts. Techniques for improving CLS are critical for maintaining visual stability on your site. Visit our guide on how to fix CLS issues for more insights.
First Input Delay (FID)
First Input Delay measures the time it takes for a page to become interactive. Ideally, FID should be under 100 milliseconds, with up to 300 milliseconds being seen as needing improvement (Coralogix).
| FID Score | User Experience |
|---|---|
| < 100 milliseconds | Good |
| 100 – 300 milliseconds | Needs Improvement |
| > 300 milliseconds | Poor |
Enhancing FID can involve optimising JavaScript execution and reducing the impact of third-party code. For detailed best practices, refer to our article on FID best practices.

Google’s Core Web Vitals Signals
Understanding how Google’s Core Web Vitals metrics affect your website’s SEO is crucial. Among these, page performance scores and the Interaction to Next Paint (INP) metric play significant roles.
Page Performance Scores
Page performance scores are derived from the three Core Web Vitals metrics: Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), and Interaction to Next Paint (INP). Each of these metrics assesses a different aspect of user experience that directly impacts your website’s performance.
| Metric | Acceptable Range | Description |
|---|---|---|
| LCP | < 2.5 seconds | Measures loading performance |
| CLS | < 0.1 | Measures visual stability |
| INP | < 200 milliseconds | Measures responsiveness after page load |
Optimising these metrics can help you enhance user experience and improve your rankings in search engine results. For further insights on how these metrics influence your site, consider exploring core web vitals and its significance in today’s digital landscape.
Interaction to Next Paint (INP) Metric
The Interaction to Next Paint (INP) metric was introduced in 2024 as an evolution of the First Input Delay (FID) metric. INP focuses on measuring how quickly a web page is responsive after it has loaded, offering a more reliable measure of user experience related to interactivity.
The ideal INP time is 200 milliseconds or less, ensuring that users have a smooth and responsive interaction with your website. By prioritising this metric, you can enhance user satisfaction and reduce frustration, which contributes to improved engagement with your site.
To delve deeper into responsiveness optimisations, refer to our resources on FID best practices and web performance metrics that will guide you in achieving excellent scores in these critical areas.
In summary, monitoring and optimising your page performance scores and understanding the INP metric will significantly enhance your SEO strategy, helping you to rise in the search rankings while offering your users a seamless experience.

Strategies for Optimisation
Optimising your Core Web Vitals (CWV) is essential for enhancing user experience and boosting your SEO rankings. Here are several strategies to improve your metrics effectively:
- Largest Contentful Paint (LCP) Optimisation:
- Ensure that your server response times are quick. Consider using a Content Delivery Network (CDN) to reduce load times.
- Optimise images and videos by compressing them without losing quality. Use formats like WebP for faster loading.
- Minimise CSS and JavaScript files to reduce the rendering time.
- Cumulative Layout Shift (CLS) Management:
- Always specify size attributes for images and video elements. This helps the browser allocate space while the content is loading.
- Avoid inserting content above existing content that could push things down as the page loads. Implement a placeholder for dynamic content.
- Use CSS to ensure stable layout design, preventing unexpected shifts.
- First Input Delay (FID) Improvement:
- Reduce JavaScript execution time by splitting up long tasks using requestIdleCallback or web workers.
- Minimise third-party scripts that can interfere with responsiveness. Consider loading them asynchronously.
- Leverage caching for frequently used scripts to decrease load time on repeat visits.

Impact on User Experience and Rankings
Improving your CWV metrics can significantly affect how users interact with your website and influence your position in search engine rankings:
- User Experience: Faster load times, fewer layout shifts, and responsive interactions enhance user satisfaction. Users are more likely to stay on your site and interact with content if their experience is seamless and visually stable.
| CWV Metric | Ideal Range |
|---|---|
| Largest Contentful Paint (LCP) | ≤ 2.5 seconds |
| Cumulative Layout Shift (CLS) | ≤ 0.1 |
| First Input Delay (FID) | ≤ 100 milliseconds |
- SEO Rankings: Google has incorporated Core Web Vitals as a ranking signal, making these metrics vital for your search visibility. Market Brew indicates that sites that perform well on CWV metrics are favoured in search rankings. If your website fails to meet CWV standards, it could negatively impact your position on search engine results pages (SERPs).
In short, investing time and resources into understanding and optimising your CWV metrics will not only improve user engagement on your site but also enhance your overall SEO strategy.
