Why Multilingual Ghost Blogs Matter

Ghost is a fast, SEO‑friendly publishing platform, but its default setup only serves one language. For businesses targeting a global audience, that limits reach and hurts search rankings. Translating each post manually is time‑consuming and error‑prone. With SiteLocaleAI, you can:

• Generate SEO‑indexed translations in eight languages automatically.
• Localize prices using psychological rounding per currency.
• Pre‑render translated pages so crawlers see the full content.
• Stay in control by using your own LLM API keys (Claude, GPT‑4o‑mini, etc.).

The result? Higher organic traffic, better user experience, and a scalable workflow that grows with your content calendar.

1. Install the SiteLocaleAI Library in Ghost

SiteLocaleAI is a framework‑agnostic, drop‑in JavaScript library. Adding it to a Ghost theme is as simple as editing the default.hbs layout file.

<!-- Add this before the closing </body> tag -->
<script src="https://cdn.sitelocaleai.com/site-locale.js"></script>
<script>
  SiteLocale.init({
    apiKey: 'YOUR_LLM_API_KEY', // e.g., Claude or GPT‑4o‑mini key
    defaultLang: 'en',
    supportedLangs: ['es','fr','de','it','pt','ja','zh','ru'],
    roundPrices: true,
    priceRounding: {
      // Example: $9.99 → €9.90, ¥1,200 → ¥1,200 (no rounding needed)
    }
  });
</script>

Place the snippet in partials/footer.hbs or any template that loads on every page. The library will automatically detect text nodes, translate them via your LLM, and replace the content on the client side.

2. Pre‑Render Translations for Search Engines

Search‑engine bots don’t execute JavaScript reliably. To ensure they index the translated content, use the SiteLocaleAI CLI to generate static HTML for each language.

# Install the CLI globally (Node.js required only for the build step)
npm i -g @sitelocaleai/cli

# Pre‑render the Spanish version of your Ghost site
npx sitelocale-cli pre-render \
  --lang es \
  --source ./content \
  --output ./public/es

Repeat the command for each language (fr, de, it, pt, ja, zh, ru). The CLI fetches the live Ghost JSON API, runs translations through your LLM, and writes fully rendered HTML files. Deploy the generated folders alongside your original site, e.g., example.com/es/, example.com/fr/, etc.

Tip: Add a simple robots.txt rule to allow crawlers to discover language folders:

Sitemap: https://example.com/sitemap.xml
Allow: /es/
Allow: /fr/

3. Localize Prices with Psychological Rounding

International shoppers respond better to prices ending in “9” or “99”. SiteLocaleAI can apply psychological rounding per currency automatically.

SiteLocale.translatePrice({
  amount: 12.49,
  currency: 'EUR',
  locale: 'fr'
}); // → €12.90

The library uses a configurable rounding table (see the priceRounding option in the init script). This ensures your product pages feel native to each market.

4. Integrate with Ghost’s SEO Tools

Ghost’s built‑in SEO meta fields accept custom values. After translation, you can inject language‑specific meta tags using the same library.

<script>
  // After the page is translated, update meta tags
  SiteLocale.on('translated', (lang) => {
    const metaTitle = SiteLocale.translateText('{{meta_title}}', lang);
    const metaDesc  = SiteLocale.translateText('{{meta_description}}', lang);
    document.querySelector('meta[name="title"]').setAttribute('content', metaTitle);
    document.querySelector('meta[name="description"]').setAttribute('content', metaDesc);
  });
</script>

Now each language version has its own meta title and description, boosting click‑through rates in regional SERPs.

5. Deploying the Multilingual Ghost Site

1. Build your Ghost site as usual (ghost build).
2. Run the CLI for each language to generate static HTML.
3. Upload the language folders to your hosting provider (Netlify, Vercel, or any static host).
4. Configure redirects so /es/ maps to the Spanish home page, etc.
5. Submit sitemaps for each language in Google Search Console.

6. Monitoring SEO Performance

After launch, track rankings per language using tools like Ahrefs or SEMrush. Look for:
- Increased organic impressions in target countries.
- Lower bounce rates on translated pages.
- Higher conversion rates after price rounding.

If you notice gaps, tweak the prompt sent to the LLM. SiteLocaleAI lets you customize the translation prompt via the promptTemplate option in the init script.
