Automate Ghost Blog Multilingual SEO in 8 Languages
“Reach every corner of the world with a single click.” – SiteLocaleAI
Why Multilingual SEO Matters for Ghost
Ghost is a powerful, open‑source publishing platform loved by writers and marketers alike. However, its default setup serves content in a single language, limiting organic traffic to the language of the original post. By automatically translating posts into eight languages (English, Spanish, French, German, Italian, Japanese, Chinese, Portuguese) and localizing prices, you can:
- Capture search traffic from 30+ countries.
- Increase average session duration and lower bounce rates.
- Boost conversions with price rounding that matches local buying psychology.
SiteLocaleAI makes this possible with a self‑hosted, framework‑agnostic JavaScript library and a CLI for SEO pre‑rendering that serves fully translated HTML to crawlers.
1. Prerequisites
| Item | Minimum Version |
|---|---|
| Ghost | 5.0+ |
| Node.js | 18.x |
| LLM API key (Claude, GPT‑4o‑mini, etc.) | – |
| SiteLocaleAI npm package | @sitelocaleai/translate |
Make sure you have a self‑hosted LLM API key; SiteLocaleAI never stores your data.
2. Install the SiteLocaleAI Library
Add the library to your Ghost theme with a single script tag. Because the library is framework‑agnostic, you don’t need any build step.
<!-- In your <head> or before </body> -->
<script src="https://cdn.sitelocaleai.com/v1/translate.min.js"></script>
<script>
// Initialize with your LLM API key and target languages
SiteLocaleAI.init({
apiKey: 'YOUR_LLM_API_KEY',
languages: ['en', 'es', 'fr', 'de', 'it', 'ja', 'zh', 'pt'],
priceRounding: true, // enable psychological rounding per currency
defaultLang: 'en'
});
</script>
Tip: Keep the API key out of the client bundle by using a server‑side proxy that injects it at runtime. The library also supports a Node.js‑less WordPress plugin, but for Ghost you’ll typically use the CDN script.
3. Auto‑Translate Blog Posts
SiteLocaleAI automatically scans the DOM for elements with the data-sitelocale attribute. In your Ghost theme, wrap the post title and content like this:
<h1 data-sitelocale="title">{{title}}</h1>
<div data-sitelocale="content">{{content}}</div>
When a visitor lands on /es/your-post, the library will:
1. Detect the language from the URL (/es/).
2. Request a translation from your LLM.
3. Replace the innerHTML of the marked elements.
4. Apply price localization (e.g., $19.99 → €17.99).
The translation happens client‑side for users, but for SEO we need the same content pre‑rendered on the server.
4. SEO Pre‑Rendering CLI
SiteLocaleAI ships a CLI that crawls your Ghost site, renders each language version, and writes static HTML files. Search engines then index the translated pages directly.
# Install the CLI globally (once)
npm i -g @sitelocaleai/cli
# Run the pre‑renderer
sitelocaleai prerender \
--site https://your-ghost-blog.com \
--out ./public/translated \
--langs en,es,fr,de,it,ja,zh,pt \
--api-key YOUR_LLM_API_KEY
The CLI performs the following steps:
- Fetches each post URL.
- Uses a headless Chromium instance to execute the JS library.
- Saves the fully translated HTML to ./public/translated/<lang>/....
After rendering, point your web server (or CDN) to the public/translated folder. Ghost’s routing can be configured to serve the static files for language‑specific sub‑paths.
5. Localizing Prices with Psychological Rounding
SiteLocaleAI’s priceRounding option automatically:
- Detects currency symbols.
- Rounds to the nearest “psychologically appealing” figure (e.g., $19.99 → $19.95, €17.99 → €17.90).
- Adjusts the currency format per locale.
You can also manually invoke the helper in your templates:
{{#if @site.currency}}
<span data-sitelocale="price">{{price}}</span>
{{/if}}
The library will replace the raw price with a localized version when the language changes.
6. Integrating with Ghost’s Routing
Add a simple routing rule in routes.yaml to direct language prefixes to the pre‑rendered folder:
routes:
/es/:
controller: channel
template: index
redirect: /translated/es/
/fr/:
controller: channel
template: index
redirect: /translated/fr/
# repeat for other languages
Now a request to https://your-ghost-blog.com/es/your-post serves the static, SEO‑ready HTML.
7. Testing & Validation
- Google Search Console – Submit the new language URLs under URL Inspection to verify indexing.
- Lighthouse – Run an audit for each language version; you should see a Performance score > 90 because the pages are static.
- Schema.org – The CLI preserves your existing JSON‑LD markup, so rich results remain intact.

9. Going Live
- Deploy the pre‑rendered folder to your production server or CDN.
- Update your DNS/Cloudflare cache settings to respect language sub‑paths.
- Monitor traffic in Google Analytics – you should see a lift in organic sessions from non‑English regions within weeks.
