Performance is a product feature. Users feel it before they read a single headline.
Prioritize the critical path
Optimize what the user waits for first: fonts, above-the-fold content, and primary interactions.
Measure continuously
Use Core Web Vitals and real-user monitoring. Lab scores alone can hide regressions.
Keep the architecture honest
Component boundaries, caching strategy, and data fetching patterns determine whether performance improvements stick—or evaporate after the next feature ship.
