| First Input Delay (FID) | Longer delays can inhibit user interaction, affecting conversions. |
Monitoring your CWV will provide valuable insights into user interactions and how effectively your eCommerce website meets their needs. Exploring topics such as site speed optimisation, and web performance metrics will equip you with the knowledge needed to enhance your website’s performance continually.
Key Metrics for CWV
Understanding the core metrics that comprise Core Web Vitals (CWV) is essential for optimising your ecommerce website. These metrics serve as indicators of user experience and heavily influence search engine rankings and visitor satisfaction. Here are the key metrics to monitor:
First Contentful Paint (FCP)
First Contentful Paint (FCP) measures the time it takes for the browser to render the first piece of content, such as text or an image, on the webpage. It serves as an essential component of user experience since it provides the first visual feedback to users. A fast FCP means that users perceive the website as loading quickly.
| FCP Benchmark | Description |
|---|---|
| Good | Less than 1 second |
| Needs Improvement | 1 – 2.5 seconds |
| Poor | More than 2.5 seconds |
For optimisation strategies, refer to our guide on FCP optimisation strategies.
Largest Contentful Paint (LCP)
Largest Contentful Paint (LCP) measures the time taken for the largest element on the page to become visible to the user. This is typically the largest image or block of text. Google recommends aiming for an LCP time of less than 2.5 seconds. Improving LCP scores is crucial for user satisfaction.
| LCP Benchmark | Description |
|---|---|
| Good | Less than 2.5 seconds |
| Needs Improvement | 2.5 – 4 seconds |
| Poor | More than 4 seconds |
Key strategies for enhancing LCP include image optimisation and minimising extra code. For more details, check out LCP optimisation techniques.
Cumulative Layout Shift (CLS)
Cumulative Layout Shift (CLS) evaluates the visual stability of a webpage. A low CLS score indicates that users will have a smoother experience without unexpected shifts in content layout, which can be frustrating. A good CLS score is considered 0.1 or lower.
| CLS Benchmark | Description |
|---|---|
| Good | 0 – 0.1 |
| Needs Improvement | 0.1 – 0.25 |
| Poor | More than 0.25 |
To learn more about optimising your CLS score, review our resources on how to improve CLS score and how to fix CLS issues.
First Input Delay (FID)
First Input Delay (FID) measures the time from when a user first interacts with your website (like clicking a link or tapping a button) to when the browser responds to that interaction. A low FID indicates that your website is highly responsive, leading to a better user experience.
| FID Benchmark | Description |
|---|---|
| Good | Less than 100 ms |
| Needs Improvement | 100 – 300 ms |
| Poor | More than 300 ms |
