Scaling International SEO for 20+ Client Sites with SiteLocaleAI

“One library, dozens of languages, zero extra hosting cost.” – Agency Lead

Managing SEO for a portfolio of 20+ client websites can feel like juggling flaming torches. You need consistent translations, accurate price localization, and search‑engine‑friendly pages—all while keeping costs under control. SiteLocaleAI solves this problem with a self‑hosted, framework‑agnostic JavaScript library that lets you plug in any LLM API key (Claude, GPT‑4o‑mini, etc.). Below is a step‑by‑step SEO guide for agencies that want to license SiteLocaleAI at scale.

1. Choose the Right Volume License

Plan	Monthly Cost per Site	Features
Indie	$5	Basic translation, price rounding
Starter	$49	CLI SEO pre‑rendering, WordPress plugin
Growth	$99	Unlimited LLM calls, priority support
Enterprise	$249	Dedicated account manager, on‑prem deployment

For an agency with 20+ sites, the Growth tier is usually the sweet spot: unlimited API calls mean you won’t hit per‑site caps, and you get priority support for any integration hiccups.

2. Install the Library Across All Projects

SiteLocaleAI works with any front‑end stack—React, Vue, plain HTML, Shopify, WordPress, you. The simplest way to add it is via npm or a CDN script tag.

# Using npm (recommended for CI pipelines)
npm i @sitelocaleai/core

<!-- CDN fallback for quick prototyping -->
<script src="https://cdn.sitelocaleai.com/v1/sitelocaleai.min.js"></script>

2.1 Centralized Configuration

Create a shared config file (sitelocale.config.js) that each client site can import. This file pulls the LLM API key from an environment variable, sets the default language, and enables price rounding.

// sitelocale.config.js
export const localeConfig = {
  // Use a vault or CI secret manager to inject the key per client
  apiKey: process.env.SITELOCALEAI_API_KEY,
  // Default language fallback
  defaultLang: "en",
  // Psychological rounding per currency (e.g., $9.99 → $10)
  priceRounding: true,
  // List of target locales for this client
  locales: ["en", "es", "fr", "de", "ja"],
};

Each client’s entry point then initializes SiteLocaleAI:

import { initLocale } from "@sitelocaleai/core";
import { localeConfig } from "../sitelocale.config.js";

initLocale(localeConfig);

Because the library is framework‑agnostic, you can drop the same snippet into a WordPress theme’s functions.php, a Shopify liquid file, or a Vue component.

3. Automate SEO Pre‑Rendering with the CLI

Search engines can’t always execute JavaScript, so you need pre‑rendered HTML for each language version. SiteLocaleAI ships a CLI that crawls your site, translates the content, and outputs static HTML files ready for indexing.

# Run once per build (e.g., in your CI pipeline)
sitelocaleai prerender \
  --site https://clientA.com \
  --output ./dist/prerendered \
  --locales es,fr,de,ja

Add the command to your GitHub Actions workflow:

name: Build & Deploy
on: [push]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - name: Install deps
        run: npm ci
      - name: Build site
        run: npm run build
      - name: Pre‑render SEO pages
        env:
          SITELOCALEAI_API_KEY: ${{ secrets.SITELOCALEAI_API_KEY }}
        run: |
          npx sitelocaleai prerender \
            --site https://clientA.com \
            --output ./dist/prerendered \
            --locales es,fr,de,ja
      - name: Deploy to Netlify
        uses: netlify/actions/cli@master
        with:
          args: deploy --dir=./dist/prerendered

The CLI respects the price rounding rules you set in the config, so the generated pages show locally appropriate pricing (e.g., €9.90 → €10).

4. WordPress Integration – No Node.js Required

Many agency clients still run on WordPress. SiteLocaleAI offers a plugin that adds a settings page for the API key and automatically injects the translation script.

Upload the plugin zip via the WordPress admin → Plugins → Add New.
Activate and navigate to Settings → SiteLocaleAI.
Paste the LLM API key and select target languages.
Enable “SEO Pre‑Render on Publish” – the plugin will call the CLI in the background and store static HTML in the wp-content/uploads/locale folder.

Tip: Pair the plugin with a caching layer (e.g., WP Rocket) to serve the pre‑rendered pages instantly.

5. Centralized Monitoring & Reporting

With 20+ sites, you need a dashboard to track translation health, price‑rounding accuracy, and SEO indexing status. SiteLocaleAI provides a webhook that fires after each pre‑render job:

// webhook-handler.js
export default async function handler(req, res) {
  const { site, locale, status } = req.body;
  // Log to your analytics platform
  await logToAnalytics({ site, locale, status });
  res.status(200).json({ received: true });
}

Configure the webhook URL in the CLI config (--webhook https://agency‑dashboard.com/api/locale‑status). Your internal dashboard can then show a simple table:

Site	Locale	Status
clientA.com	es	✅ Rendered
clientB.com	ja	❌ Error (API limit)

6. Best Practices for International SEO

Practice	Why it matters	How SiteLocaleAI helps
Hreflang tags	Directs Google to the correct language version	The library automatically injects `<link rel="alternate" hreflang="...">` based on your locale list.
Localized URLs	Improves click‑through rates	Use the `localePath` helper to generate `/es/`, `/fr/` prefixes.
Currency‑specific meta tags	Signals price relevance to search engines	`priceRounding` ensures the `<meta property="og:price:amount">` reflects the rounded value.
Sitemap per language	Guarantees crawlability	Run `sitelocaleai sitemap --locales es,fr,de,ja` to generate language‑specific sitemaps.
