LCP, INP, and CLS sound technical — but they directly affect SEO, ads quality scores, and conversions. Here is the practical version.
• LCP (Largest Contentful Paint): how fast the main content appears
• INP (Interaction to Next Paint): how responsive the page feels when users click
• CLS (Cumulative Layout Shift): how much the layout jumps while loading
Huge unoptimised images, render-blocking scripts, heavy page builders, and layout shifts from late-loading ads or fonts.
Many “beautiful” sites fail vitals because decoration was prioritised over delivery.
1. Image and font strategy
2. Critical rendering path and third-party scripts
3. Server/edge caching and modern frameworks
4. Template-level layout stability
Then we re-measure on real devices — not just lab scores.
