How do I monitor website performance?

Monitor website performance using a combination of tools. Google PageSpeed Insights provides Core Web Vitals scores and recommendations. Chrome DevTools offers detailed performance analysis. Real User Monitoring (RUM) tools like Google Analytics or specialized services track actual user experiences. Synthetic monitoring tools test performance from various locations. Use performance budgets to catch regressions. Set up alerts for performance degradation. Monitor key metrics like load time, Time to Interactive, and Core Web Vitals. Track performance over time to identify trends. Example: A team uses PageSpeed Insights for quick checks, Chrome DevTools for deep dives, and RUM for real-world performance tracking, catching issues before users are affected.
