Scaling Multilingual SEO for 20+ Client Sites with SiteLocaleAI

If you run an agency that services dozens of brands, the biggest headache is keeping every site translated, price‑localized, and SEO‑friendly without blowing up your budget. SiteLocaleAI solves this by giving you a **self‑hosted, framework‑agnostic JavaScript library* that works with any stack—React, Vue, WordPress, Shopify, you. Below is a step‑by‑step SEO guide that shows how to set up a volume‑licensed workflow for 20+ client sites.

---

1. Why Choose a Self‑Hosted Solution?

Traditional SaaS	SiteLocaleAI (Self‑Hosted)
Pay‑per‑translation	Fixed volume license (e.g., $49 Starter, $99 Growth)
Limited API key control	Use your own Claude, GPT‑4o‑mini, or any LLM API key
No price‑localization logic	Built‑in psychological rounding per currency
SEO indexing only for original language	Pre‑rendered, fully translated pages for crawlers

By hosting the library yourself, you keep API costs predictable, maintain data privacy, and can scale across client sites with a single license.

---

2. Setting Up the Global Library (One‑Time per Agency)

Create a shared npm package (or a simple Git submodule) that all client projects import. This ensures a single source of truth for configuration, versioning, and updates.

# In your agency repo
mkdir site‑locale‑shared && cd site‑locale‑shared
npm init -y
npm i site‑localeai

src/index.js – central configuration:

// src/index.js
import { SiteLocale } from 'site-localeai';

// Load your LLM API key from environment (keep it secret!)
const LLM_API_KEY = process.env.LLM_API_KEY;

export const locale = new SiteLocale({
  apiKey: LLM_API_KEY,
  provider: 'openai', // or 'anthropic', 'cohere', etc.
  defaultLang: 'en',
  // Enable price rounding for 10+ currencies
  priceOptions: {
    rounding: 'psychological', // 9.99 → 9.95, 19.99 → 19.95, etc.
    currencyMap: {
      USD: 'USD', EUR: 'EUR', GBP: 'GBP', JPY: 'JPY',
      // add more as needed
    },
  },
  // SEO pre‑render flag – true for all client sites
  seoPreRender: true,
});

Now each client site can simply import locale and call translatePage().

3. Integrating Into a Client Site (Framework‑Agnostic)

3.1. Drop‑In Script Tag (No Build Tools Required)

<script type="module">
  import { locale } from 'https://cdn.jsdelivr.net/npm/site-localeai@latest/dist/index.js';
  // Initialize with client‑specific settings (override defaults)
  locale.init({
    targetLang: 'es', // Spanish for this client
    priceCurrency: 'EUR',
  });
  // Translate the whole page once DOM is ready
  window.addEventListener('DOMContentLoaded', () => locale.translatePage());
</script>

3.2. React / Vue Component Wrapper

// src/LocaleWrapper.jsx
import { useEffect } from 'react';
import { locale } from '../site-locale-shared/src/index';

export default function LocaleWrapper({ lang, currency, children }) {
  useEffect(() => {
    locale.init({ targetLang: lang, priceCurrency: currency });
    locale.translatePage();
  }, [lang, currency]);
  return <>{children}</>;
}

Use <LocaleWrapper lang="de" currency="GBP"> around your app’s root component.

4. Volume Licensing – Managing 20+ Sites Efficiently

SiteLocaleAI’s volume licensing works on a per‑seat basis. For an agency with 20+ sites, the Growth plan ($99/month) covers up to 30 sites, while the Enterprise plan ($249/month) removes the site cap.

Tips for managing licenses:
1. Centralize API keys – store them in a secret manager (e.g., Vault, AWS Secrets Manager) and inject them into each site’s CI pipeline.
2. Tag client sites – use a naming convention like client‑<slug>-locale to track usage in your monitoring dashboard.
3. Automated health checks – schedule a nightly script that calls locale.healthCheck() for every site and alerts you if any translation fails.

# health-check.sh
#!/usr/bin/env bash
for site in $(cat sites.txt); do
  curl -s -X POST "https://api.sitelocaleai.com/health" \
    -H "Authorization: Bearer $LLM_API_KEY" \
    -d "{\"site\":\"$site\"}" | jq .
 done

5. SEO Pre‑Rendering – Let Google Index Every Language

SiteLocaleAI’s CLI can pre‑render static HTML for each locale, ensuring search engines see fully translated content.

# Install the CLI globally (once per agency)
npm i -g site-localeai-cli

# Pre‑render all client sites (assumes each site lives in ./sites/<slug>)
for dir in ./sites/*; do
  site-localeai-cli prerender \
    --src $dir \
    --out $dir/dist \
    --langs en,es,de,fr,ja \
    --price-currency EUR,USD,JPY
 done

The generated dist/ folder contains language‑specific index.html files (e.g., index.es.html). Configure your web server to serve the correct file based on the Accept‑Language header or URL prefix (/es/).

SEO benefits:
- Full crawlability – Google can index each language version without JavaScript execution.
- Localized schema markup – the CLI injects <link rel="alternate" hreflang="..."> tags automatically.
- Reduced bounce rate – visitors land on a page in their native language with correctly rounded prices.

6. WordPress Integration – No Node.js Required

For clients on WordPress, SiteLocaleAI offers a plugin that bundles the library and CLI into a simple admin UI.

1. Install the plugin via the WordPress dashboard.
2. In Settings → SiteLocaleAI, paste your LLM API key.
3. Choose target languages and price rounding options.
4. Click Generate Translations – the plugin runs the CLI on the server and writes static HTML files to the /locale/ directory.

The plugin also adds a Gutenberg block <site-locale> that you can drop into any page for on‑the‑fly translation when needed.

7. Monitoring & Analytics

SiteLocaleAI ships with a lightweight dashboard (hosted on your own domain) that shows:
- Translation success rate per site
- API usage (tokens per language)
- SEO index coverage (via Google Search Console API)

Embed the dashboard in your agency’s internal portal for a single pane of glass.
