Translating SaaS Pricing Pages with LLMs Using SiteLocaleAI

Published on SiteLocaleAI.com

Why pricing pages need more than literal translation

When a SaaS company expands beyond its home market, the pricing page becomes the first point of contact for prospects. A literal translation can break the buying flow if:

Currency symbols are wrong or missing.
Numbers are not rounded to the psychological sweet spots that shoppers expect (e.g., $9.99 instead of $10).
SEO bots only see the original language, hurting organic traffic in target markets.

SiteLocaleAI solves all three problems with a single, framework‑agnostic JavaScript library, a CLI for static pre‑rendering, and a WordPress plugin that requires no Node.js.

1. Install the library (drop‑in, framework‑agnostic)

# Using npm or yarn – you can also load the bundle from a CDN
npm install @sitelocaleai/sdk
# or
yarn add @sitelocaleai/sdk

Add the script to your HTML head (or import it in your bundler):

<script src="https://cdn.sitelocaleai.com/sdk/v1.0.0/locale.min.js"></script>

2. Initialise with your LLM API key

SiteLocaleAI is self‑hosted – you provide the API key of the LLM you trust (Claude, GPT‑4o‑mini, etc.).

import { Locale } from '@sitelocaleai/sdk';

const locale = new Locale({
  // Your LLM endpoint – can be OpenAI, Anthropic, etc.
  llmEndpoint: 'https://api.openai.com/v1/chat/completions',
  apiKey: process.env.LLM_API_KEY,
  // Target languages you want to support
  locales: ['en', 'es', 'de', 'fr', 'ja'],
  // Price localisation options
  priceOptions: {
    // Psychological rounding per currency
    rounding: {
      USD: 0.99,
      EUR: 0.95,
      GBP: 0.99,
      JPY: 0, // JPY uses whole numbers
    },
    // Currency format strings
    format: {
      USD: '${{amount}}',
      EUR: '€{{amount}}',
      GBP: '£{{amount}}',
      JPY: '¥{{amount}}',
    },
  },
});

The priceOptions object tells SiteLocaleAI how to round and format numbers for each locale. The library will automatically replace any element with a data-price attribute.

3. Markup your pricing page

Add a few data attributes to the HTML you already have. No redesign needed.

<div class="pricing-card" data-locale="en">
  <h2>Starter</h2>
  <p class="price" data-price="19.00">$19.00</p>
  <ul>
    <li>10 projects</li>
    <li>5 GB storage</li>
  </ul>
</div>

When the page loads, SiteLocaleAI will:
1. Detect the visitor’s language (or read a lang query param).
2. Send the surrounding text (title, feature list) to the LLM for context‑aware translation.
3. Apply the rounding rules defined in priceOptions and replace the price string.

4. Run the SEO CLI for static pre‑rendering

Search engines struggle with client‑side rendering. SiteLocaleAI’s CLI can generate fully translated, static HTML files that you can serve to crawlers.

n Install the CLI globally (once)
npm i -g @sitelocaleai/cli

# Generate pre‑rendered pages for all locales
locale-cli prerender \
  --src ./public \
  --out ./dist \
  --locales en,es,de,fr,ja \
  --api-key $LLM_API_KEY

The CLI reads every HTML file in ./public, runs the same translation pipeline, and writes locale‑specific files (/en/index.html, /es/index.html, …). You can then configure your web server to serve the correct version based on the Accept‑Language header.

Tip: For a quick test, run locale-cli prerender --dry-run to see which files will be processed.

5. WordPress integration (no Node required)

If your pricing page lives on WordPress, install the SiteLocaleAI plugin from the WordPress marketplace. After activation:

Add your LLM API key in Settings → SiteLocaleAI.
Enable “Price localisation” and set the rounding rules in the plugin UI.
Use the [locale] shortcode to wrap any pricing block:

[locale]
<div class="price" data-price="49.00">$49.00</div>
[/locale]

The plugin injects the same JavaScript bundle and handles the translation on the server side for SEO crawlers.

6. Validate the output

After deployment, verify two things:

Human test: Open the page with a VPN or Chrome language switcher. Prices should appear as $19.99, €19.95, ¥2100, etc., and the copy should read naturally.
SEO test: Use curl -H "Accept-Language: de" https://yourdomain.com/pricing and inspect the returned HTML. You should see the German translation and the correctly rounded price.
