Translate Your WordPress Blog to Spanish for SEO Success
International traffic is a goldmine for any content‑driven site, but it only pays off when search engines can actually see the translated pages. SiteLocaleAI gives you a self‑hosted, LLM‑powered solution that works inside WordPress, automatically translates posts, localizes prices, and pre‑renders SEO‑friendly HTML. Below is a practical, end‑to‑end tutorial that takes a typical English‑language WordPress blog and makes it fully indexable for Spanish speakers.
1. Prerequisites
| Item | Why you need it |
|---|---|
| WordPress 5.8+ | Modern block editor support |
| Access to an LLM API key (Claude, GPT‑4o‑mini, etc.) | SiteLocaleAI runs on your own keys, keeping data private |
| Node.js (optional) | Only needed for the CLI pre‑render step |
| Basic FTP/SSH access | To upload the JavaScript library if you prefer manual hosting |
2. Install the SiteLocaleAI WordPress Plugin
- From the WordPress admin, go to Plugins → Add New.
- Search for "SiteLocaleAI" and click Install Now.
- Activate the plugin.
- Navigate to Settings → SiteLocaleAI.
- Paste your LLM API key.
- Set Target Language to
es(Spanish). - Enable Price Rounding if you want psychological price rounding per currency.
- Save changes.
The plugin automatically injects the required JavaScript snippet into every front‑end page, so you don’t have to touch your theme files.
3. Fine‑Tune Translation with the Drop‑In JS Library (Optional)
If you need custom selectors—for example, you have a special price element or a hero banner—you can add a tiny configuration block to your theme’s footer.php or via a custom HTML widget.
<script src="https://cdn.sitelocaleai.com/v1/locale.js"></script>
<script>
window.localeConfig = {
apiKey: "YOUR_LLM_API_KEY",
targetLang: "es",
rounding: true,
selectors: {
price: ".price",
content: ".post-content"
}
};
</script>
apiKey can be left empty if you already entered it in the plugin settings – the library will read it from the global configuration.
4. Pre‑Render Spanish Pages for Search Engines
Search engines still struggle with JavaScript‑only content. SiteLocaleAI’s CLI solves this by generating static HTML snapshots that Google, Bing, and Yandex can crawl.
4.1 Install the CLI (one‑time)
npm install -g @sitelocaleai/cli
4.2 Run the pre‑render command
npx sitelocaleai pre-render --lang es --output ./public_es
--lang estells the CLI to request Spanish translations from your LLM.--output ./public_escreates a folder that mirrors your site structure but with fully rendered Spanish HTML.
4.3 Serve the pre‑rendered version
You have two simple options:
- Sub‑directory – Add a rewrite rule in
.htaccess(Apache) ornginx.confthat points/es/*topublic_es/*. - Separate sub‑domain – Point
es.yourdomain.comto thepublic_esfolder.
Both approaches let crawlers discover the Spanish URLs (https://yourdomain.com/es/your‑post) and index the translated content just like any native page.
5. Verify SEO Indexing
- Use Google Search Console → URL Inspection on a Spanish URL. You should see a “Submitted URL appears in Google index” status.
- Run a
curl -I https://yourdomain.com/es/sample-postand confirm theContent‑Language: esheader is present. - Check the rendered HTML source – you’ll see the translated text, localized prices, and
<link rel="alternate" hreflang="es" href="...">tags automatically added by SiteLocaleAI.
6. Keep Your Translations Fresh
Whenever you publish a new post, the plugin queues a translation request to your LLM. The CLI can be scheduled via a cron job to re‑run the pre‑render step nightly:
0 2 * * * /usr/local/bin/npx @sitelocaleai/cli pre-render --lang es --output /var/www/html/public_es >> /var/log/localeai.log 2>&1
This ensures that new content appears in the Spanish index within a few hours.
7. Advanced: Price Localization with Psychological Rounding
SiteLocaleAI can convert $19.99 to €17 (rounded to the nearest whole euro) or £15 (rounded to the nearest 5‑pound step). Enable this in the plugin settings or add:
window.localeConfig.rounding = {
enabled: true,
strategy: "psychological" // rounds to 0, 5, 9, 99, etc.
};
The library automatically detects currency symbols and applies the appropriate rounding per locale.
