Core Web Vitals
Core Web Vitals is a set of three metrics (LCP, CLS, INP) that Google uses to measure the real user experience of a website’s speed and stability.
LCP measures how quickly the main content renders, CLS measures how much a page "moves" during loading (such as a button shifting just as you were about to click it), and INP measures interaction responsiveness - how quickly the site responds to a click or tap.
These three metrics have been part of Google’s page-ranking algorithm since 2021. They are not merely technical details for developers, but a real factor in whether a website reaches the customer in search results at all.
They cannot be improved with a single trick. They require deliberate decisions across the whole website: what renders on the server and what in the browser, where content has reserved space (to prevent CLS), and how much JavaScript the site sends to the client. That is exactly what a conversion rate audit and a redesign address - Core Web Vitals are not a separate task; they are a by-product of a properly built website.
