Episode notes
Invest In UX Before Cosmetic Code
- Prioritize user research and UX over polishing CSS when the product serves people in distress.
- Spend budget on understanding users rather than superficial front-end tweaks.
Core Web Vitals As Predictors
- Core Web Vitals are good predictors of perceived speed but not absolute guarantees.
- They provide an accessible, standardized way to gauge site speed at scale.
Measure What Matters To Your Product
- Use Core Web Vitals first, then add custom metrics that reflect your product's key interactions.
- Measure meaningful actions like 'time to see balance' or 'time to add to cart' for your domain.
