Understanding Google's Core Web Vitals: LCP, CLS, and INP
Core Web Vitals measure three dimensions of user experience. Largest Contentful Paint (LCP) measures how fast the main content of a page loads — it should happen within 2.5 seconds. Cumulative Layout Shift (CLS) measures visual stability — unexpected layout jumps (like an image pushing text down) create a frustrating experience that Google penalises. Interaction to Next Paint (INP) replaced FID in 2024 and measures overall page responsiveness — how quickly the page reacts to all user interactions, not just the first one. Failing any of the three can suppress your rankings.
Why Mobile Core Web Vitals Matter More Than Desktop
Google uses mobile-first indexing, meaning your mobile CWV scores are the ones that influence rankings — not your desktop scores. Most sites pass desktop CWV with ease but fail on mobile due to unoptimised images, heavy JavaScript that blocks rendering, and font loading delays. When auditing your CWV, always check mobile scores first. If you're short on development resources, prioritise the mobile CWV fixes that block the most ranking potential.
The Developer Handoff: Turning CWV Data into Fixes
The gap between knowing your CWV scores and actually improving them is usually a developer communication problem. Developers need specific information: which element is the LCP element (use Chrome DevTools to identify it), what is causing the CLS (look for images without width/height attributes, dynamic content insertion, and late-loading web fonts), and which interactions are slow for INP (use the Interaction Observer in DevTools). Our checker provides this information in developer-ready format, reducing back-and-forth and getting fixes shipped faster.
