What it actually means
Core Web Vitals are Google's page experience signals, and they influence SERP ranking. Google's targets: LCP under 2.5 seconds, INP under 200ms, CLS under 0.1. Shopify themes vary: newer themes tend to pass, older themes and app-heavy stacks often fail. Mobile vitals matter more than desktop for most eCommerce stores.
