Interaction to Next Paint (INP)

التفاعل حتى الرسم التالي

Google's responsiveness Core Web Vital that replaced First Input Delay (FID) in March 2024. INP measures the delay between a user's click or keypress and the next visible visual update. Target: under 200ms for a 'good' score. Common INP failures on bilingual Gulf sites: heavy JavaScript bundles, third-party analytics scripts, and large Arabic font files blocking the main thread. Must be audited separately from LCP.

Core Web VitalsGoogle's three quantified user-experience signals that are ranking factors: Largest Contentful Paint (LCP, target < 2.5 s), Interaction to Next Paint (INP, target < 200 ms), and Cumulative Layout Shift (CLS, target < 0.1). Gulf sites with heavy Arabic fonts and right-to-left layouts must be explicitly tuned — naive ports from LTR templates commonly fail CLS and LCP thresholds.
Performance OptimizationOptimizing site speed through image compression, caching, CDN delivery, and code splitting. Target: Core Web Vitals (LCP < 2.5s, FID < 100ms, CLS < 0.1). Faster sites rank higher and convert better.
Largest Contentful Paint (LCP)The time from page navigation start until the largest visible image or text block is rendered. Google's threshold for a 'good' score is under 2.5 seconds. Common culprits on Gulf bilingual sites: unoptimised hero images, render-blocking Arabic web fonts loaded from external CDNs, and server response latency when hosting is geographically distant from Saudi Arabia or UAE data centres.
Server-Side Rendering (SSR)Generating full HTML on the server for every request so search engine crawlers and social-media scrapers receive complete content instantly. Contrasts with client-side rendering (CSR), where JavaScript must execute before content appears. SSR is the preferred architecture for Gulf-facing sites that need strong Arabic SEO and fast Time to First Byte on mobile networks.
