রাজশাহীর যে কোনো ব্যবসার জন্য ওয়েবসাইট এখন মূল sales channel. কিন্তু Slow load, layout shift, delayed click response—এই তিনটা সমস্যা আপনার conversion কে নষ্ট করে। Google-এর Core Web Vitals (CWV)—LCP, INP, CLS—ঠিক থাকলে ranking, CTR, conversion—সব বেড়ে যায়.
Good news: BD IT CENTER (Top-Rated Web Development Company in Bangladesh) Rajshahi ও Bangladesh জুড়ে CWV-focused development + BDIX-powered hosting দিয়ে আপনার সাইটকে fast, stable & SEO-ready করে।
LCP (Largest Contentful Paint): main content কত দ্রুত দেখা যায়। Target ≤ 2.5s
INP (Interaction to Next Paint): user action-এর পরে response কত দ্রুত। Target ≤ 200ms
CLS (Cumulative Layout Shift): layout jump কম। Target < 0.1
Impact: Better CWV ⇒ Better UX ⇒ Lower bounce, Higher sales, Higher Google rank (especially on mobile).
Unoptimized images (no AVIF/WebP, no proper sizing)
Render-blocking CSS/JS and unused libraries
Slow hosting / no BDIX peering
Fonts causing FOIT/FOUT
Third-party widget bloat (chat, trackers, ads)
Cumulative Layout Shift from banners/ads/dynamic sections
Poor caching policies and no CDN
Audit & Benchmark: Lighthouse/CrUX-style audit; establish baseline LCP/INP/CLS
Image Strategy: Next-gen formats (WebP/AVIF), responsive srcset, lazy-loading, proper aspect-ratio to prevent CLS
Critical CSS & Defer: Extract critical CSS, defer non-critical JS, reduce bundle with tree-shaking & code-splitting
Font Performance: display=swap, preload key fonts, avoid layout shift from font metrics
Server & CDN: BDIX hosting, HTTP/2/3, full-page caching, edge caching, Brotli
CLS Hardening: reserve space for images/ads, skeletons/shimmers, predictable component heights
INP Tuning: event delegation, avoid heavy main-thread work, Web Worker offload, remove jQuery bloat
Database & API: query optimization, object cache, route caching
Monitoring: real-user metrics dashboard + alerting
Iteration: A/B test changes, target LCP ≤2.0s, INP ≤150ms, CLS <0.05 where feasible
Faster = Better Crawl & Index: Less server timeouts, more pages discovered
Higher Page Experience signals: Improves competitive tie-breaks in SERP
Better Engagement: Higher dwell time boosts ranking signals indirectly

Q1. কত দিনে result পাব?
A. Basic fixes 3–7 days; complex themes/eCommerce 1–3 weeks. We show before/after CWV.
Q2. Hosting পরিবর্তন লাগবে?
A. Not always, but BDIX hosting usually trims LCP significantly. We migrate if it clearly benefits.
Q3. WordPress-এ সম্ভব?
A. হ্যাঁ. We harden themes, trim plugins, optimize media, and still keep editor-friendly UX.
Q4. INP কমছে না কেন?
A. Heavy JS, third-party scripts, long tasks. We profile, split code, move work off main thread.
Q5. Maintenance দরকার?
A. Yes. New content/plugins can regress CWV. Our Ongoing Care plan prevents that.
