Your Asian Customers Are Bouncing. Here's Why.

If you're a VP of Marketing watching conversion drop 60% in Japan, Korea, and Taiwan, you're running English-only infrastructure in a multilingual world.

Custom multilingual corporate websites supporting 3 to 30+ languages with proven i18n architecture. Vercel Edge middleware for automatic locale detection, Sanity CMS with locale fields, hreflang implementation, RTL support for Arabic and Hebrew, CJK typography, and design tokens that adapt per locale. Built by a team that localises across 30 languages, led by founder Gautam Khorana, who has worked on 5,000+ websites across his career.

Multilingual Corporate Web Development

Multilingual corporate web development is the engineering discipline of building production websites that serve distinct language and locale experiences from a single codebase — without duplicating infrastructure. It covers locale routing, translated content pipelines, hreflang signaling for search engines, and locale-aware UI rendering including RTL and CJK script support. The result is a site where every international visitor lands in their language automatically, with no redirect chains and no degraded experience.

What is holding your current website back?

Common gaps we find in nearly every audit.

Your Japanese and Korean visitors hit an English page, find no language switcher, and exit within seconds — your analytics show it as a high bounce rate with no obvious cause.
Risk: Lost enterprise pipeline in APAC markets where first-impression trust is a prerequisite for any procurement conversation, and no amount of paid media spend recovers a failed first load.
Your marketing team maintains separate WordPress instances per region, leading to content drift, inconsistent brand messaging, and a translation workflow that runs weeks behind product releases.
Risk: Compliance risk in regulated markets where mistranslated product claims carry legal exposure, and operational cost that scales poorly as you enter each additional locale.
Your current site renders Arabic and Hebrew in LTR layout, breaking visual hierarchy and making forms unusable — your Middle East resellers have flagged it repeatedly with no resolution from your current agency.
Risk: Permanent credibility damage with distributors and buyers who interpret a broken RTL layout as a signal that the vendor does not treat their market seriously.

How We Build This Right

Every safeguard, built in from Day 1.

hreflang Implementation

Every locale variant is declared with correct hreflang and x-default tags in both the HTML head and XML sitemap, ensuring search engines index the correct language page for each target market and avoiding duplicate content penalties across regions.

GDPR and Regional Consent Handling

Consent management is scoped per locale, with cookie banners, data processing disclosures, and opt-in flows that meet GDPR requirements in the EU, APPI in Japan, and PIPL in China — all served from the same middleware layer without separate deployments.

Core Web Vitals Per Locale

Each locale is tested independently against LCP, CLS, and INP thresholds using Vercel Analytics and Lighthouse CI in the deployment pipeline, because CJK font loading and RTL stylesheet injection introduce performance regressions that only surface under locale-specific conditions.

What We Build

Purpose-built features for your industry.

Vercel Edge Locale Detection

Middleware running at the edge reads Accept-Language headers and geo-IP signals before the request reaches the origin, routing visitors to their correct locale without a client-side redirect. This eliminates the flash of untranslated content and keeps Time to First Byte consistent across regions.

Sanity CMS with Locale Field Architecture

Content is modeled in Sanity with locale-specific field groups, allowing editors to manage translations inline without switching documents. Locale completeness validation prevents a page from publishing in a target language until all required fields are filled, removing the risk of partial translations reaching production.

RTL and CJK Typography Systems

Design tokens are keyed by locale group, swapping font stacks, line-height scales, and letter-spacing values automatically when Arabic, Hebrew, Japanese, Korean, or Traditional Chinese is active. RTL layout is applied via logical CSS properties rather than mirrored stylesheets, keeping the codebase maintainable as locales are added.

Translation Pipeline Integration

We connect Sanity to your existing translation management system — Phrase, Lokalise, or Crowdin — via webhook-triggered sync, so your localization team works in familiar tooling while translated strings flow back into the CMS automatically. Human review gates are enforced before any locale goes live.

Our Development Process

From discovery to launch. Quality at every step.

01

Locale Audit and Architecture Planning

1-2 weeks

We inventory your target locales, identify script and layout requirements, map your existing content structure, and define the routing strategy — subdirectory, subdomain, or ccTLD — based on your SEO and infrastructure constraints. Deliverable is a signed-off i18n architecture document before any code is written.

02

CMS Schema and Translation Pipeline Setup

2 weeks

Sanity schemas are built with locale field groups, validation rules, and completeness checks. We configure the integration with your translation management system, establish webhook flows, and run an end-to-end test with a sample content type so your localization team can validate the workflow before full content migration begins.

03

Frontend Build with Locale-Aware Design Tokens

3-4 weeks

Next.js or Astro pages are built against a token system that adapts typography, spacing, and directionality per locale group. Edge middleware is configured and tested across all target locales, and RTL layouts are verified against physical devices for Arabic and Hebrew before staging sign-off.

04

hreflang, QA, and Staged Rollout

1-2 weeks

hreflang tags and sitemaps are generated programmatically from the locale configuration and validated against Google Search Console. Each locale is tested for Core Web Vitals, translation completeness, and consent flow correctness before a phased rollout that holds your primary locale stable while activating international variants one region at a time.

Frequently Asked Questions

Custom multilingual websites start at $12,000 for 3 to 5 languages with locale-aware CMS and hreflang implementation. Enterprise builds supporting 10 to 30+ languages with RTL support, CJK typography, Edge locale detection, and market-specific layouts range from $20,000 to $30,000. Professional translation is included in all packages -- we never use machine translation for production content.
Our i18n engine supports 30+ languages in production today, including Latin, CJK (Chinese, Japanese, Korean), RTL (Arabic, Hebrew, Farsi), Cyrillic (Russian, Ukrainian), and Indic scripts (Hindi, Tamil, Bengali). Each language gets proper typography, font stacking, text direction, and culturally-adapted layouts -- not just translated text in the same template.
We deploy Vercel Edge middleware that runs at the CDN edge in 100+ global locations. It detects the visitor's preferred language from their browser settings and geographic IP, then serves the correct locale version with zero latency. Users can manually switch languages via a persistent selector. The detection respects user preferences and never overrides manual selection.
Hreflang tags tell search engines which language version of a page to show to users in different regions. Without proper hreflang, Google might show your English page to French searchers or create duplicate content penalties. We implement hreflang across every page, handle x-default fallbacks, manage regional variants (en-US vs en-GB, pt-BR vs pt-PT), and validate the implementation with automated testing.
Yes. RTL support is built into our i18n architecture from the foundation. We implement CSS logical properties for automatic layout flipping, bidirectional text handling for mixed RTL-LTR content, Arabic and Hebrew typography with proper font stacking, and mirrored navigation and UI components. The entire layout transforms -- it is not just text alignment.
We recommend Sanity CMS with locale-aware document fields for most multilingual projects. Editors work in a side-by-side interface showing source and target languages simultaneously. Each locale has its own content fields, publication status, and preview URL. For simpler projects, we use Supabase with a locale column and slug-based routing.
Yes. Our architecture supports per-locale layout variants. Japanese pages can have higher information density, Arabic pages use RTL layout with mirrored navigation, German pages accommodate longer text strings, and Chinese pages integrate with local social platforms. Each market gets a design adapted to its cultural expectations, not a one-size-fits-all template.
A 3 to 5 language website takes 8 to 12 weeks including translation and localization. Enterprise projects with 10 to 30+ languages, RTL support, and market-specific layouts take 12 to 16 weeks. We phase language rollouts so your primary markets launch first while additional locales follow in subsequent sprints.
