Practical checklist for Core Web Vitals in Magento:
- LCP: optimize hero, reduce critical JS, verify page cache.
- CLS: set fixed dimensions for images and banners.
- TTFB: review Redis/Varnish, full page cache, and warmup.
If LCP is high, it’s usually assets + cache. If TTFB is high, it’s backend or infrastructure.
Operational tip: measure before and after with Lighthouse + CrUX, not just local Lighthouse.
