Auto‑Translate Ghost Blog Posts into 8 Languages for SEO
Published on SiteLocaleAI Blog • 2026‑08‑12
Overview
Ghost is a popular, headless CMS that powers fast, SEO‑friendly blogs. Pairing Ghost with SiteLocaleAI lets you automatically generate localized versions of every post in eight languages, complete with culturally‑aware price rounding and fully indexable HTML for search engines. This use‑case walks you through the entire pipeline:
- Add the SiteLocaleAI JavaScript library to your Ghost theme (framework‑agnostic).
- Configure self‑hosted LLM keys (Claude, GPT‑4o‑mini, etc.).
- Run the CLI to pre‑render static, translated pages for crawlers.
- Verify SEO metadata and price localization.
- Deploy and watch your international traffic rise.
The result is a set of static, language‑specific URLs (e.g., /es/, /fr/, /ja/) that Google can crawl and rank, while your visitors get a seamless, native‑language experience.
1. Install the SiteLocaleAI Library
SiteLocaleAI ships as a tiny drop‑in script that works with any front‑end framework, including the Handlebars templates Ghost uses. Add the script tag to your default.hbs (or any layout file that wraps your content):
<!DOCTYPE html>
<html lang="en">
<head>
{{!-- Existing meta tags --}}
<script src="https://cdn.sitelocaleai.com/v1/site-locale.min.js" defer></script>
<script>
// Initialise SiteLocaleAI with your LLM API key and target languages
window.SiteLocaleAI.init({
apiKey: "{{@site.lm_api_key}}", // store securely in Ghost settings
languages: ["es", "fr", "de", "ja", "pt", "hi", "en-GB", "en-AU"],
priceRounding: "psychological" // round to 0.99, 0.95, etc.
});
</script>
</head>
<body>
{{!-- Your theme content --}}
{{{body}}}
</body>
</html>
Tip: Keep the API key out of the public repo. Ghost’s code injection feature lets you store it as a site‑wide custom setting (
{{@site.lm_api_key}}).
2. Mark Up Translatable Content
SiteLocaleAI scans the DOM for elements with a data-translate attribute. Wrap the parts you want translated—titles, paragraphs, and price blocks:
<article class="post">
<h1 data-translate="title">{{title}}</h1>
<section data-translate="body">
{{content}}
</section>
<p class="price" data-translate="price" data-currency="USD">${{price}}</p>
</article>
When the page loads, the library sends the source text to your chosen LLM, receives translations, and injects them into the DOM. The data-currency attribute tells SiteLocaleAI which currency to localize; the library then applies psychological rounding (e.g., $9.99 → €8.95 for EU markets).
3. Pre‑Render SEO‑Friendly Pages with the CLI
Search engines struggle with client‑side rendering. SiteLocaleAI’s CLI generates static HTML for each language, which you can serve directly from Ghost’s static assets folder.
Install the CLI globally
npm i -g @sitelocaleai/cli
Run the pre‑render command
site-locale-cli render \
--src ./content/themes/your-theme \
--out ./content/themes/your-theme/static-localized \
--langs es,fr,de,ja,pt,hi,en-GB,en-AU \
--api-key $SITELOCALEAI_API_KEY
The CLI does the following:
1. Crawls every post URL.
2. Calls the LLM for each language.
3. Writes a language‑specific HTML file (/es/your-post/, /fr/your-post/, …).
4. Generates a sitemap.xml entry for each version.
Hook the output into Ghost
Copy the generated static-localized folder into Ghost’s content directory and add a simple rewrite rule in routes.yaml:
routes:
/es/:
controller: static
content: static-localized/es
/fr/:
controller: static
content: static-localized/fr
# …repeat for other languages
After restarting Ghost (ghost restart), each language version is served as a static HTML page, guaranteeing that Google can index the fully translated content.
4. Verify SEO Metadata
SiteLocaleAI also translates meta tags. In your default.hbs, add placeholders that the library will replace:
<title data-translate="meta-title">{{title}} – {{@site.title}}</title>
<meta name="description" data-translate="meta-description" content="{{excerpt}}">
When the CLI runs, it creates language‑specific <title> and <meta> tags, keeping them under the 65‑character and 155‑character limits respectively. You can double‑check the output by opening a generated file in a browser and inspecting the head.
5. Deploy and Monitor
Push your updated theme and static files to your hosting provider (e.g., Heroku, Render, or a self‑hosted VPS). Then:
- Submit the new sitemap to Google Search Console.
- Track language‑specific traffic in Google Analytics (use the
hlquery parameter or separate view filters). - Monitor LLM usage via your provider’s dashboard to keep costs under control.
6. Bonus: Price Localization with Psychological Rounding
SiteLocaleAI’s priceRounding option automatically adjusts prices to match local consumer expectations. For example:
| Currency | Original | Rounded |
|---|---|---|
| USD | $12.00 | $11.99 |
| EUR | €10.00 | €9.95 |
| JPY | ¥1300 | ¥1299 |
This subtle tweak can increase conversion rates by up to 7 % according to internal A/B tests.
