Google’s Core Metrics
Google’s Core Web Vitals consist of three key metrics that evaluate website performance and user experience:
- Largest Contentful Paint (LCP): This measures loading performance, specifically how long it takes for the largest element on your page to become visible to the user. A good LCP score is typically 2.5 seconds or less.
- Cumulative Layout Shift (CLS): This assesses visual stability by measuring how much the content shifts during the loading phase, which can be frustrating for users. A CLS score of less than 0.1 is considered ideal.
- First Input Delay (FID): This metric gauges interactivity by measuring the time it takes for the page to respond to the first user interaction. A FID of less than 100 milliseconds is an optimal target.
The following table summarises these core metrics for quick reference:
| Metric | Definition | Ideal Value |
|---|---|---|
| Largest Contentful Paint (LCP) | Loading performance | ≤ 2.5 seconds |
| Cumulative Layout Shift (CLS) | Visual stability | ≤ 0.1 |
| First Input Delay (FID) | Interactivity | ≤ 100 milliseconds |
These metrics are critical in helping Google evaluate website performance. They allow for the identification of areas for improvement, ensuring a better experience for users. For more details on these metrics, visit our section on understanding core web vitals.
Improving your Core Web Vitals not only enhances user experience but also positively influences your website’s visibility in search results. This understanding is essential for New Zealand business owners and marketing professionals looking to optimise their online presence.
Key Core Web Vitals Metrics
Understanding the key metrics of Core Web Vitals is essential for enhancing your website’s performance and user experience. These metrics focus on loading speed, responsiveness, and visual stability—attributes that influence both user satisfaction and search engine rankings.
Largest Contentful Paint (LCP)
Largest Contentful Paint (LCP) measures how quickly the largest visible element on the screen loads. This could be an image, video, or text block, and it plays a vital role in determining the perceived loading speed of your webpage. According to Google, the ideal LCP time should be 2.5 seconds or less to provide a positive user experience.

Interaction to Next Paint (INP)
Interaction to Next Paint (INP) assesses how responsive a webpage is after it has fully loaded. It measures the time it takes for a webpage to react to user interactions like clicks or taps. A recommended INP time is 200 milliseconds or less to ensure a smooth and efficient interaction for users.
| INP Performance | Time (milliseconds) | Experience Level |
|---|---|---|
| Good | ≤ 200 | Highly responsive |
| Needs Improvement | 200 – 500 | Potential delays |
| Poor | > 500 | Noticeable lag |
For best practices on enhancing INP, you can refer to our article on FID best practices.
Cumulative Layout Shift (CLS)
Cumulative Layout Shift (CLS) evaluates the visual stability of your webpage as it loads. This metric quantifies all the unexpected layout shifts that may occur, which can lead to a poor user experience. A good CLS score should be 0.1 or less.
| CLS Performance | Scale | Experience Level |
|---|---|---|
| Good | ≤ 0.1 | Stable visual layout |
| Needs Improvement | 0.1 – 0.25 | Minor shifts noticeable |
| Poor | > 0.25 | Major shifts causing issues |
