What is Core Web Vitals?
Core Web Vitals are Google's three measurements of real-user page experience: LCP (Largest Contentful Paint — how fast the main content appears, target under 2.5 seconds), INP (Interaction to Next Paint — how quickly the page responds to taps), and CLS (Cumulative Layout Shift — how much the layout jumps around while loading). Google collects these from actual Chrome users and factors them into rankings.
They matter doubly in India, where much traffic arrives on mid-range phones over inconsistent mobile networks — a page that feels fine on office broadband may take eight seconds on a customer's connection, and most visitors abandon by three. The usual fixes are unglamorous: compress images to WebP, avoid heavy page builders and scripts, enable caching, and reserve space for images so content does not jump.
