A practical look at how to use Lighthouse for Next.js apps: what to pay attention to, what to ignore, and how to focus on real user experience instead of chasing perfect scores.
1Treat Lighthouse as a lab smoke test, not the ultimate judge of UX
2Focus on LCP, INP, and CLS rather than the raw 0-100 score
3Use Lighthouse to catch obvious issues, field data to set priorities
4Optimize images, fonts, and client JS before overhauling architecture
5Be honest with stakeholders: above a certain point, higher scores don't equal better UX
