Core Performance Metrics
The updated audit will prioritize metrics that directly correlate with user experience and accessibility. Crucial performance metrics will include First Input Delay (FID), Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), and Time to Interactive (TTI). These metrics, when measured together, paint a more comprehensive picture of user experience than traditional metrics.
Calculation and Measurement
FID, LCP, CLS, and TTI are calculated by analyzing user interactions with the page. Lighthouse instruments browser events and measures the time taken to complete specific milestones. For instance, FID measures the delay between a user interaction (like a click or a touch) and the browser’s response. LCP identifies the largest image or text element to appear on the screen and records the time it takes to load and render it.
CLS tracks unexpected layout shifts during page load, which can cause frustrating user experiences. TTI measures the time until the page is fully interactive and usable by the user.
Tools for Preparation
Numerous tools aid developers in understanding and improving their website’s performance. Performance profiling tools such as Chrome DevTools, WebPageTest, and Lighthouse itself are valuable resources. Using these tools, developers can pinpoint areas for optimization and analyze their website’s performance in various scenarios. Testing different scenarios and user environments through these tools allows developers to gain a more comprehensive understanding of how their website performs for diverse user profiles and devices.
Improving User Experience and Accessibility
The new metrics directly improve user experience by focusing on real-world interaction. A low FID, for example, ensures quick responses to user actions. A fast LCP reduces perceived load time, making the page feel more responsive. Minimizing CLS prevents jarring layout shifts that disrupt user flow. These metrics, when optimized, result in a more enjoyable and predictable browsing experience.
Furthermore, optimizing these metrics enhances accessibility by ensuring a seamless experience for users with various devices and disabilities.
Example Improvements
| Metric | Problem | Solution | Expected Impact |
|---|---|---|---|
| First Input Delay (FID) | High delay between user interaction and browser response. | Optimize JavaScript execution, reduce unnecessary DOM manipulations, and use asynchronous operations. | Faster response to user input, improved perceived responsiveness. |
| Largest Contentful Paint (LCP) | Long time for the largest visible content to load. | Optimize images (use appropriate formats, compression), lazy load non-critical content, and improve server response times. | Faster initial content rendering, improved perceived page load speed. |
| Cumulative Layout Shift (CLS) | Unexpected layout shifts during page load. | Use fixed positioning for elements, avoid using images that load asynchronously, and use appropriate styles. | Improved page stability and user experience, prevents jarring or unexpected page re-layouts. |
| Time to Interactive (TTI) | Long time for the page to become fully interactive. | Reduce initial load time, minimize the use of heavy JavaScript, and ensure asynchronous execution of scripts. | Faster page interaction, quicker availability of page functionality. |
