How do I make my store load fast enough to pass Core Web Vitals?
The short answer
Run your homepage and a product page through PageSpeed Insights and GTmetrix before you touch anything - you're aiming for LCP under 2.5s, INP under 200ms and CLS under 0.1, with a realistic working target of LCP under 3s on Indian 4G. Images are usually 60-80% of your page weight, so compress and lazy-load them first, then audit every installed app - each one injects scripts on every page even if it's only used on one, and app bloat is the single biggest speed killer on Indian Shopify stores. Numbers change, but the pattern holds: a Delhi store that did this dropped its mobile PageSpeed score from 32 to 78 and roughly doubled mobile conversion - speed isn't cosmetic, it's a conversion lever.
