Why Pricing Pages Need More Than Literal Translation

A pricing page is the final gate before a visitor becomes a paying customer. Translating the UI text is only half the battle—prices must feel natural in each market. Psychological rounding (e.g., $9.99 → €9.90) improves conversion, while search engines need fully rendered HTML to index the localized content.

SiteLocaleAI solves all three problems in one self‑hosted JavaScript library:

  1. Framework‑agnostic drop‑in – works with React, Vue, WordPress, Shopify, or plain HTML.
  2. LLM‑driven context – you supply your own Claude, GPT‑4o‑mini, or other API keys, keeping data private.
  3. Price localization – automatic rounding per currency and locale.
  4. SEO pre‑rendering CLI – generates static HTML for crawlers.
  5. WordPress plugin – no Node.js required for non‑technical teams.

Below is a practical, step‑by‑step walkthrough for a SaaS startup called Acme Analytics that wants to launch its pricing page in the US, EU, and Japan.

1. Install the Library (Drop‑in)

# Using npm (optional – you can also load from CDN)
npm i @sitelocaleai/core

Add the script tag to the <head> of your HTML. The CDN version works even if you don’t have a bundler:

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

Because the library is framework‑agnostic, you can place it on any page, including a static HTML pricing page.

2. Initialise with Your LLM API Key

// locale.js – load once per page
const locale = new SiteLocaleAI({
  // Provide your own LLM endpoint. SiteLocaleAI supports OpenAI, Anthropic, etc.
  llm: {
    provider: "openai",
    apiKey: "YOUR_OPENAI_API_KEY",
    model: "gpt-4o-mini"
  },
  // Enable price localisation
  price: {
    enabled: true,
    // Map of currency to rounding rules (psychological)
    rounding: {
      USD: 0.99,
      EUR: 0.90,
      JPY: 0 //n    }
  }
});

All subsequent calls to locale.translate() will automatically use this configuration.

3. Markup Your Pricing Elements

SiteLocaleAI looks for data-locale-key attributes. Add them to every textual element and price you want to translate.

<div class="pricing-card" data-locale-key="plan.pro">
  <h2>Pro</h2>
  <p data-locale-key="plan.pro.description">
    All features for growing teams.
  </p>
  <span class="price" data-price="49" data-currency="USD" data-locale-key="plan.pro.price"></span>
</div>

The data-price attribute holds the base amount in USD. The library will:

  • Convert the amount to the visitor’s locale currency (using an exchange‑rate API you configure).
  • Apply the rounding rule defined in the price.rounding map.
  • Format the number according to locale conventions (e.g., ¥5,500 vs 5 500 ¥).

4. Provide Translation Context for the LLM

LLMs translate better when they understand the domain. You can pass a JSON‑structured prompt that includes product‑specific terminology.

const context = {
  product: "Acme Analytics",
  terms: {
    "dashboard": "Analytics dashboard",
    "subscription": "Monthly subscription",
    "team": "Team collaboration"
  },
  tone: "professional, friendly"
};

locale.translateAll({ context });

translateAll scans the DOM for data-locale-key attributes, sends the keys and context to the LLM, and injects the translated strings.

5. SEO‑Friendly Pre‑Rendering (CLI)

Search engines can’t execute JavaScript reliably for dynamic translations. SiteLocaleAI ships a CLI that pre‑renders the localized HTML for each target locale.

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

# Generate static pages for en, fr, ja
sitelocaleai prerender \
  --src ./public/index.html \
  --out ./dist \
  --locales en,fr,ja \
  --config ./locale-config.json

locale-config.json contains the same LLM and price settings as the client‑side init. The CLI produces index.en.html, index.fr.html, etc., which you can serve via your CDN. Search bots will index the fully translated markup, boosting international SEO.

6. WordPress Integration (No Node Required)

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

  1. Add the SiteLocaleAI Settings page under Settings → SiteLocaleAI.
  2. Paste your LLM API key and configure rounding.
  3. Use the Gutenberg block Localized Text to wrap any text you want translated.
  4. For price fields, use the Localized Price block and set the base USD amount.

The plugin injects the same JavaScript library and automatically runs translateAll() on page load. No npm or build step is needed.

7. Testing the Experience

# Run a local server that simulates different locales
npx serve ./dist -p 8080
# Open Chrome dev tools → Network → Override → Accept‑Language: ja-JP

Verify that:

  • All UI strings appear in Japanese.
  • Prices are converted to JPY and rounded to the nearest whole yen (e.g., ¥5,500).
  • The <title> and <meta description> tags are also translated – you can set them via data-locale-key="meta.title" and data-locale-key="meta.description".

8. Monitoring & Analytics

Because the translation happens client‑side, you can capture conversion metrics per locale without extra infrastructure. Add a small event to fire after translation completes:

locale.on('ready', () => {
  // Example: Google Analytics event
  gtag('event', 'price_page_localized', {
    locale: locale.currentLocale,
    price: document.querySelector('.price').innerText
  });
});

Combine this data with your existing funnel to see which locales drive the highest sign‑up rates.
