Some technical aspects and metrics related to website performance:
1. Page Speed Index (PSI): Page Speed Index is a metric that evaluates how quickly the content of a webpage becomes visible to users. It measures the perceived loading speed from the user's perspective and considers elements like First Contentful Paint (FCP) and Largest Contentful Paint (LCP). A lower PSI score indicates faster loading times and a better user experience.
2. Time to First Byte (TTFB): Time to First Byte measures the time it takes for the server to send the first byte of data in response to a user's request. A lower TTFB indicates a more responsive server, which is crucial for reducing waiting times and improving overall page load speed.
4. Image Optimization: Large and unoptimized images can significantly slow down page load times. Compressing images and using modern image formats like WebP can help reduce file sizes without compromising on quality.
5. Cache Performance: Caching involves storing website data locally on a user's device or in an intermediary server to reduce server load and improve load times for returning visitors. Monitoring cache hit rates and effectiveness helps ensure efficient use of caching strategies.
7. Time to Interactive (TTI): TTI measures the time it takes for a webpage to become fully interactive, allowing users to interact with buttons, forms, and other elements. Faster TTI ensures a smoother user experience and encourages increased engagement.
8. Error Monitoring: Tracking and addressing server errors, broken links, and other technical issues are essential for maintaining a smooth user experience. Regular error monitoring and prompt resolution are crucial for website performance.
9. Mobile Performance: Mobile devices have become the dominant platform for web browsing. Monitoring key mobile performance metrics like Mobile PageSpeed, Mobile First Contentful Paint, and Mobile Time to Interactive helps optimize mobile experiences.
10. Web Vitals: Web Vitals are a set of essential user-centric metrics introduced by Google that focus on key aspects of user experience, including Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS). These metrics provide actionable insights into website performance from the user's perspective.
11. Server Response Time: Server response time, also known as Time to First Byte (TTFB), measures how quickly a server responds to a user's request. A fast server response time is crucial for reducing waiting times and improving overall page load speed.
