Localization Growth Strategy for AI Products: Multilingual Implementation and Globalization Guide

Issue 1: Route Matching Conflicts

Problem Description:Next.js's [locale] dynamic route may incorrectly match Chinese paths. For example, /seo/learn-seo might be incorrectly identified as a locale parameter, causing Chinese pages to return 404.

Solution:Use generateStaticParams() in app/[locale]/layout.tsx to explicitly specify supported locales:

export function generateStaticParams() {
  return [{ locale: 'en' }]; // Only generate English routes
}

At the same time, strictly validate the locale parameter in the layout:

if (locale !== 'en') {
  return null; // Return null to let Next.js try matching other routes
}

Issue 2: Automatic Language Redirect

Problem Description:next-intl automatically redirects based on browser language by default, causing access to the root path / to be forcibly redirected to /en.

Solution:Disable automatic language detection in i18n/routing.ts:

export const routing = defineRouting({
  locales: ['zh', 'en'],
  defaultLocale: 'zh',
  localePrefix: {
    mode: 'as-needed', // Default language doesn't use prefix
    prefixes: {
      zh: '',      // Chinese: root path
      en: '/en'    // English: /en prefix
    }
  },
  localeDetection: false, // Disable automatic language detection
});

Issue 3: Middleware Route Handling

Problem Description:Need to ensure that Chinese paths (such as /seo/learn-seo) are not handled by the [locale] route, but match the root path's app/layout.tsx.

Solution:Customize middleware.ts to only apply locale processing to paths starting with /en:

export default function middleware(request: NextRequest) {
  const pathname = request.nextUrl.pathname;
  
  // Only paths starting with /en use next-intl middleware
  if (pathname.startsWith('/en')) {
    return createMiddleware(routing)(request);
  }
  
  // Other paths (Chinese paths) pass through directly without locale processing
  return NextResponse.next();
}

Issue 4: URL Duplication Caused by Language Switcher

Problem Description:The language switcher component may cause URL duplication, such as /en/en/en/seo/learn-seo.

Solution:Remove automatic language switcher buttons and switch to manual URL switching. Ensure all navigation links correctly use the getLocalizedHref() function:

const getLocalizedHref = (href: string) => {
  if (locale === 'en') {
    if (href === '/') return '/en';
    return `/en${href}`;
  }
  return href; // Chinese remains unchanged
};

Best Practices Summary

1. Clear Routing Strategy:Use generateStaticParams() to explicitly specify supported locales and avoid path mismatches
2. Disable Automatic Detection:Set localeDetection: false to prevent unexpected language redirects
3. Custom Middleware:Only apply middleware to paths that need locale processing (such as /en)
4. Manual Language Switching:Switch languages through URL paths instead of using automatic switcher components
5. Hreflang Tags:Add hreflang tags to all multilingual pages to help search engines understand language version relationships

Solving these technical issues ensures the stability and SEO-friendliness of multilingual websites. For more information about implementing Hreflang tags, refer to Google Official Documentation and Multi-Regional Site Management Guide.

Server and Brand Name

Server Selection:

• Use overseas website services and servers, register overseas companies, and do not file for domestic registration
• Overseas servers can avoid the complex process of domestic registration while providing better global access speeds
• Choose server locations close to target markets to improve access speeds and user experience

Brand Name Strategy:

• If you have both domestic and overseas products, don't use the same name or similar-sounding names
• Isolate domestic and overseas brands to prevent issues with users who mind Chinese brands and pricing problems
• Independent brand names help establish independent brand images in different markets
• Avoid brand names with negative meanings or pronunciation difficulties in different languages

Multilingual Language Research

Before starting multilingual localization, thorough language research is needed:

1. Target Market Analysis:Determine priority markets and languages to enter
2. Competitive Analysis:Understand competitors' localization levels in target markets
3. User Research:Understand target market users' search habits and language preferences
4. Keyword Research:Use localized keyword research tools (such as Yandex Wordstat, Naver DataLab)

i18n Implementation Strategy

When using i18n to create multilingual pages, we recommend the following strategy:

• Subdirectory Structure:Use subdirectories like /fe (French), /de (German), /es (Spanish), /ru (Russian) to create small language pages
• Page Priority:Only include important pages, such as:
  • Homepage
  • Features page
  • Pricing page
  • About page
  Don't translate blog articles and other batch pages
• Language Switching Method:Manually click to switch languages, no need to follow browser language switching
  • Give users clear language choice
  • Avoid user experience issues caused by automatic switching
• English Version Handling:Don't create a separate /en, use the root path as the default language (Chinese)
• SEO Optimization:Add Hreflang tags for multilingual pages
  • Help search engines understand relationships between different language versions
  • Avoid duplicate content issues
  • Improve SEO performance of multilingual pages

Multilingual Content Publishing

Publish prepared articles to other multilingual channels to achieve multilingual vertical publishing:

• Russian Market:Publish to vc.ru
  • vc.ru is Russia's largest technology and startup media platform
  • You can publish product introductions, case studies, industry insights, and more
• Korean Market:Publish to Naver
  • Naver is South Korea's largest search engine and portal
  • You can publish content through Naver Blog or Naver Post

Multilingual Vertical Publishing Strategy:For different language markets, choose mainstream platforms in those markets for content publishing, rather than simply translating English content. This can better reach target users and enhance brand awareness in local markets.

Product Localization

Product localization is not just translating interface text, but also includes:

• Feature Adaptation:
  • Adjust product features according to target market needs
  • Certain features may not be needed or need enhancement in specific markets
• UI/UX Localization:
  • Adapt to different language text lengths and reading habits
  • Consider layout requirements for right-to-left (RTL) languages
  • Adjust fonts, colors, icons, and other visual elements
• Cultural Adaptability:
  • Avoid content that may cause cultural conflicts
  • Adapt to different cultural user habits and expectations
• Compliance:
  • Comply with target market laws and regulations
  • Adapt to data protection regulations (such as GDPR)

Pricing Localization

There are two main approaches to pricing localization:

Pricing Strategy Selection Recommendations:

• For markets with lower purchasing power, True Localization can improve conversion rates
• For markets with similar purchasing power, Cosmetic Localization can simplify operations
• Consider the impact of exchange rate fluctuations and payment methods
• Regularly evaluate and adjust pricing strategies

Marketing Localization

Marketing localization requires deep understanding of target market culture and user habits:

Localization Research Content:

• Suitable Product Features:
  • QR codes: Very popular in some markets (such as China), but may not be commonly used in other markets
  • Font effects: Different cultures have different preferences for fonts and design
  • Color choices: Different cultures have different understandings and preferences for colors
• Purchasing Power Analysis:
  • Understand average income and consumption levels in target markets
  • Analyze competitor pricing strategies
  • Determine appropriate price ranges
• User Persona:
  • Understand target users' age, gender, occupation, interests, and other characteristics
  • Analyze user usage habits and preferences
  • Determine marketing channels and content strategies
• Content Review Type Differences:
  • Domestic: Mainly focus on political content
  • Overseas: Mainly focus on child pornography, violence, and other content
  • Different markets have different review standards and sensitive points

International Version Before Localization:Early users and mainstream local users have different personas, and may still use the international version. This is normal. As localization deepens, the proportion of local users will gradually increase.

User Segments

Several important points about user segments:

• Misconception About Overseas Payment Willingness:
  • The statement "overseas users have stronger payment willingness and higher payment ability" does not exist
  • Overseas also has different regions, and payment ability and willingness vary greatly between regions
  • Need to conduct research for specific markets, not generalize
• Identifying True Paying Users Through Going Global:
  • Going global can help identify users who are truly willing to pay
  • Users in different markets may have different value perceptions of products
  • Through multi-market testing, you can find the most valuable user segments
• Not Targeting Chinese Market Doesn't Mean No Chinese Customers:
  • Even if not specifically targeting the Chinese market, there may still be Chinese users using the product
  • These users usually have higher acceptance of international products
  • You can understand Chinese users' usage through data analysis
