Program
Dive into the basics of performance evaluation with quick installation of free tools like Google PageSpeed Insights and Lighthouse, interactive exploration of essential metrics such as Largest Contentful Paint and First Input Delay, practical exercises on real sites to identify bottlenecks, guided analysis of automated reports, and creation of your first personal audit with immediately applicable business recommendations.
Advance to in-depth analysis of Core Web Vitals through real-world tests with WebPageTest and Real User Monitoring, measure the impact of images, scripts, and fonts on speed, conduct comparative audits before/after optimization on the ongoing project, simulate mobile and desktop scenarios, produce personalized dashboards, and integrate alerts for continuous monitoring that transforms your skills into a certified professional asset.
