eCommerce in Kolkata: Build for Trust & Conversion

- Localized payments: UPI, Net Banking, Cards (UPI adoption is massive across India)
- Logistics integrations: Shiva Cargo Logistics, Shiprocket, BlitzShipz
- Local retail examples: Tantuja, Adi Mohini Mohan Kanjilal
Progressive Web Apps (PWA)
PWAs offer offline capability, instant loading, and lower build cost compared to native apps — often 3–4× cheaper — perfect for India’s connectivity realities.
COD & Multi-language (Bengali)
COD still drives ~60% of transactions. Localized Bengali content — including checkout flows and errors — is critical for trust and clarity.
Implement multilingual routing with Next.js to translate product pages, cart summaries, and error messages end‑to‑end.
UPI adoption is massive across India (16.99B+ transactions in January), so optimize for UPI flows.
Rural digital adoption remains ~16%, so COD and accessible content are essential.
SEO, Core Web Vitals, and Voice Search
Core Web Vitals (CWV)
- Image optimization and next-gen formats
- Reduce render-blocking JS/CSS; minimize third-party code
- Fast server response and CDN strategies
- Track LCP, INP, and CLS to guide improvements
Voice Search Optimization (VSO)
Voice search is dominating mobile queries. VSO requires a shift in content strategy from simple keywords to natural, conversational language.
- Long-Tail Keywords: Target phrases like "What is the best web development company in Kolkata for a startup?" instead of just "web development company"
- Schema Markup: Structure product, service, and FAQ content with Schema Markup to help search engines understand content as direct answers. Essential for local business visibility in Kolkata.
- Featured Snippets: Maximize chances of securing "Position Zero" — the preferred source for voice assistants
Voice search optimization is particularly important in the Indian market where mobile voice queries are growing rapidly.
