3. Understanding Scores and Metrics
3.1 Explanation of the overall score
A numerical score out of 100, indicating the overall performance of the web page. Higher scores are generally better.
And How to Interpret the score if below 100, Fast if the score between 90-100, Average if the score between 50-89 and Slow if the score between 0-49.
3.2 Details on key performance metrics (FCP, LCP, CLS, etc.)
Google PageSpeed Insights includes some several key performance metrics that impact on user experience:
First Contentful Paint (FCP): The First Contentful Paint (FCP) metric measures the time from when the user first navigated to the page to when any part of the page’s content is rendered on the screen. It’s importance is perceived speed of the page effectively
Largest Contentful Paint (LCP): The Largest Contentful Paint (LCP) is one of the three Core Web Vitals metrics, and it represents how quickly the main and largest content of a web page is loaded and it Reflects the main content’s loading speed. Specifically, Largest Contentful Paint (LCP) measures the appropriate time from when the user initiates loading the page until the largest image or text block is rendered within the viewport.
Cumulative Layout Shift (CLS): Cumulative Layout Shift (CLS) is a stable Core Web Vital metric. It is an important, user-centric metric for measuring visual stability of the page by tracking unexpected layout shifts because it helps quantify how often users experience unexpected layout shifts—a low Cumulative Layout Shift helps ensure that the page is delightful. Higher Cumulative Layout Shift can lead to a poor and bad user experience.
Total Blocking Time (TBT): The Total Blocking Time (TBT) metric measures the total amount of time after First Contentful Paint (FCP) where the main thread was blocked for long enough to prevent input responsiveness. By default, Lighthouse stops monitoring Total Blocking Time (TBT) after Time to Interactive (TTI), as do some other lab tools that measure page load. Affects interactivity; high TBT can lead to slow responsiveness.
3.4 How to interpret and prioritize issues
A higher score indicates better performance. Use the score as a general indicator of how well the page is optimized.
Opportunities highlight specific areas for improvement. Each opportunity is associated with a potential performance gain.
Prioritize issues that directly impact user experience. Focus on metrics like First Contentful Paint (FCP), Largest Contentful Paint (LCP), and Cumulative Layout Shift (CLS).
Field Data reflects real-world user experiences. Prioritize issues that have a significant impact on actual users.
Lab Data provides insights into how the page performs under ideal conditions. Use it to identify potential issues before they impact users.
Assess the severity of each opportunity. Prioritize high-impact issues that can result in substantial performance improvements.
Critical rendering path issues can significantly impact page load times. Prioritize addressing render-blocking resources, optimizing CSS and JavaScript, and reducing server response times.
Image optimization is often a high-impact opportunity. Prioritize compressing and resizing images without compromising quality.
Caching resources can improve subsequent page loads. Prioritize configuring caching policies for static assets.
