Auto‑Translate Ghost Blog Posts into 8 Languages for SEO

“One post, eight languages, full SEO indexing—no extra servers, no extra cost.” – SiteLocaleAI

Why Multilingual Ghost Content Matters

Ghost is a minimalist publishing platform that excels at speed and SEO. However, native Ghost only serves the language you write in. By automatically translating each post into the top eight target languages—English, Spanish, French, German, Italian, Japanese, Portuguese, and Russian—you:

Capture new organic traffic from non‑English search queries.
Improve dwell time with native‑language content.
Boost conversion by localizing price mentions with psychological rounding.
Maintain full control of your LLM API keys (Claude, GPT‑4o‑mini, etc.) because SiteLocaleAI runs on your own infrastructure.

Prerequisites

A Ghost installation (self‑hosted or Ghost(Pro) with custom theme access). 2. An LLM API key (Claude, GPT‑4o‑mini, etc.). 3. Node ≥ 14 for the CLI (optional but recommended). 4. Access to your site’s head template to inject a script.

1. Install SiteLocaleAI Library

Add the drop‑in script to your theme’s default.hbs (or equivalent) before the closing </head> tag:

<script type="module">
  import { SiteLocaleAI } from "https://cdn.sitelocaleai.com/v1/site-locale-ai.min.js";

  // Initialize with your LLM API key and target languages
  const sla = new SiteLocaleAI({
    apiKey: "YOUR_LLM_API_KEY",
    languages: ["es", "fr", "de", "it", "ja", "pt", "ru"], // ISO‑639‑1 codes
    priceRounding: true, // enable psychological rounding
    fallbackLanguage: "en"
  });

  // Auto‑translate the article body once the DOM is ready
  document.addEventListener("DOMContentLoaded", async () => {
    const article = document.querySelector(".post-content");
    if (!article) return;
    const original = article.innerHTML;
    const translations = await sla.translate(original);
    // Store translations in a hidden <script type="application/json"> for the CLI
    const script = document.createElement("script");
    script.type = "application/json";
    script.id = "site-locale-translations";
    script.textContent = JSON.stringify(translations);
    document.body.appendChild(script);
  });
</script>

Tip: The library is framework‑agnostic, so the same snippet works on React, Vue, Shopify, or any static site generator that outputs HTML.

2. Enable SEO Pre‑Rendering with the CLI

Search engines can’t execute JavaScript reliably for indexing. SiteLocaleAI’s CLI pre‑renders each language version into static HTML files that you can serve to crawlers.

# Install the CLI globally (requires Node)
npm i -g @sitelocaleai/cli

# Run the pre‑render step for your Ghost output folder
site-localeai prerender \
  --source ./content/ \   # Ghost’s generated HTML files
  --dest ./public/ \      # Where the static site lives
  --api-key YOUR_LLM_API_KEY \
  --langs es,fr,de,it,ja,pt,ru

The CLI reads the JSON blob injected by the script (#site-locale-translations) and creates language‑specific copies:

/es/your-post/
/fr/your-post/
…

These URLs are discoverable via <link rel="alternate" hreflang="..."> tags that the CLI adds automatically.

3. Add hreflang Tags Manually (Optional)

If you prefer to manage tags yourself, insert the following snippet into your default.hbs head section:

{{#if @site.locale}}
  <link rel="alternate" hreflang="en" href="{{url}}" />
  <link rel="alternate" hreflang="es" href="{{url}}/es/" />
  <link rel="alternate" hreflang="fr" href="{{url}}/fr/" />
  <link rel="alternate" hreflang="de" href="{{url}}/de/" />
  <link rel="alternate" hreflang="it" href="{{url}}/it/" />
  <link rel="alternate" hreflang="ja" href="{{url}}/ja/" />
  <link rel="alternate" hreflang="pt" href="{{url}}/pt/" />
  <link rel="alternate" hreflang="ru" href="{{url}}/ru/" />
{{/if}}

These tags tell Google which language version to serve to users in different regions, preventing duplicate‑content penalties.

4. Localize Prices with Psychological Rounding

If your post mentions a price, SiteLocaleAI can automatically convert and round it to the most persuasive figure for each currency (e.g., $9.99 → €8.99, ¥1,200 → ¥1,199). The priceRounding option in the initialization snippet handles this out of the box.

// Example: "Only $49.99" becomes "Only €44.99" in French, "Only ¥5,500" in Japanese, etc.

5. Test & Validate

Crawl the site with Screaming Frog or Sitebulb to verify that each language URL returns a 200 status and contains the correct <html lang="..."> attribute.
Check the Structured Data – the CLI preserves existing schema.org markup, so your article schema remains valid across languages.
Monitor Search Console – after deploying, watch the “International Targeting” report for any hreflang errors.

6. WordPress‑Style Simplicity for Ghost

Even though Ghost is not WordPress, the same self‑hosted philosophy applies. No Node.js runtime is required on the server; the translation happens client‑side and the CLI runs locally during your build pipeline.

7. Internal Resources
