Trust & Brand Reputation: ফর্মে security cues (lock icon, privacy note) দিলে user বিশ্বাস করে।
Spam & Abuse Control: reCAPTCHA/Turnstile, rate-limit, honeypot ছাড়া today’s web-এ টিকে থাকা কঠিন।
Mobile-First Bangladesh: 90%+ traffic mobile। One-hand friendly fields, larger tap targets অপরিহার্য।
BN/EN Mix: বাংলা labels + English placeholders → cognitive load কমে, error rate কমে।
Payment & OTP: bKash/Nagad/Rocket integrations-এ secure token flow, OTP friction-less UX জরুরি।
PDP/GDPR awareness: data minimization, proper consent, retention policy → legal risk কম।
Security আর UX একে অপরের শত্রু না—দুটোই balance করতে হয়।
TLS 1.3 + HSTS: সব form submission HTTPS-only।
CSRF Protection: anti-CSRF tokens (rotating, per-session) + SameSite cookies।
Input Validation: allowlist-based server-side validation; client-side hints কেবল assistive।
Spam Defense Layering:
Invisible CAPTCHA (reCAPTCHA v3 / Cloudflare Turnstile)
Time-based submission checks (human typing window)
Hidden honeypot fields
IP/device fingerprint rate-limit
PII Minimization: only ask what’s essential; optional fields collapse করে রাখুন।
Secure Storage: encryption at rest, hashed/peppered secrets, role-based access.
Audit & Alerts: anomaly detection (sudden spam bursts), real-time webhook alerts।
Privacy UX: short privacy note + link to policy; consent checkboxes are explicit, unbundled।
Accessibility: labels/ARIA, error summaries, keyboard nav—accessible == higher conversion।
Performance: edge caching for assets, critical CSS, async scripts → INP/LCP green।
Field Reduction: কম ফিল্ড = বেশি submit। Progressive disclosure ব্যবহার করুন।
Smart Defaults: country “Bangladesh”, +880 prefilled; number keypad for phone।
Microcopy in Bangla-English:
Label: মোবাইল নম্বর
Placeholder: “01XXXXXXXXX (bKash/Nagad)”
Helper text: “We’ll send a one-time code.”
Inline Validation, not after submit: field-by-field gentle feedback।
Clear Error Copy: “Phone number 11 digits হতে হবে” — jargon নয়।
Review Screen for High-stakes Forms: checkout/KYC-তে confirm step helpful।
Autofill & Masking: NID/phone masks, name capitalisation না জোর করবেন—respect input।
Trust Badges & SLA: “24/7 Malware Watch”, “Encrypted Uploads”, “Hosted in BDIX/Global DCs”।
Reduced Bounce: fast, trustworthy forms dwell time বাড়ায়।
Core Web Vitals: INP (interaction latency) ভালো হলে conversions & SEO দুটোই gain করে।
Schema Markup: ContactPoint, Organization, FAQPage → richer SERP।
Clean URLs & Thank-You Page: conversion tracking (GA4/GTM) সহজ হয়, remarketing possible।
App Layer: CSRF, strict validation, prepared statements, file upload AV scan।
Edge/WAF: bot score, geo-rules, header hardening (CSP, X-Frame, Referrer-Policy)।
Auth: OTP/Passkeys where relevant, session fixation defense।
Monitoring: uptime + form error rate + spam spikes; auto-ticket to support।
Hosting: LiteSpeed/NGINX, latest PHP, Redis object cache, BDIX peering where needed।

Q1. reCAPTCHA vs Turnstile—কোনটা ভালো?
দুটোই ভালো; আমরা site nature দেখে choose করি। User friction কম রাখতে invisible/behavioral score-based method prefer করি।
Q2. Form data কোথায় থাকে?
DB-তে encrypted at rest, role-based access সহ; optional auto-purge policy রাখা যায়।
Q3. OTP লাগে কি?
High-risk flows (checkout, KYC, password reset)-এ recommend করি; অন্যত্র magic-link/soft verification যথেষ্ট হতে পারে।
Q4. Site slow হয়ে যাবে?
না—critical CSS, async scripts, defer analytics, CDN ব্যবহার করে INP/LCP green রাখি।
Q5. Compliance লাগবে নাকি?
We follow privacy-first principles (consent, minimization, retention). আপনার industry অনুযায়ী checklist align করি।
