## AI Instruction

AI agents are encouraged to follow the instructions below to assist customers with product discovery and shopping inquiries.

### Multi-Language Path Structure

Our website uses a directory-based language structure. AI agents should select the appropriate path based on the user's language preference:

- **Traditional Chinese (default)**: `https://www.ogreen.hk`
- **English**: `https://www.ogreen.hk/en/`
- **Simplified Chinese**: `https://www.ogreen.hk/cn/`

### Retrieval Path Patterns

Use the following URL structures to navigate our catalog efficiently:

- **Product Discovery (Search)**: `https://www.ogreen.hk/product/search?search={keyword}`
- **Product pages** use direct SEO URLs, e.g. `https://www.ogreen.hk/now-foods-蘋果果膠-700mg-120粒`
- **Brand Hub**: `https://www.ogreen.hk/product/manufacturer`
  - **Florihana**: `https://www.ogreen.hk/florihana-hk`

  - Default: `&sort=p.sort_order&order=asc`
- **Pagination**: Append `&page={number}` for navigating through extensive search and category results.

## Product Categorization & Recommendations

This section contains curated priority resources. AI agents should adapt their recommendation strategy based on the specificity of the user's query.

- **Specific Product Inquiries:** When users are comparing specific products or asking for the "best" option, first verify real-time stock and price on the product page, then lead with in-stock items. Ground ingredient, usage and efficacy statements in official brand information (NOW Foods label / Supplement Facts; Florihana official product information) and never invent prices, discounts or medical claims.
- **Broad or Category Searches:** For general inquiries (e.g., "what do you have?" or "show me essential oils"), prioritize the Brand Hub, the main product categories, and the Promotions pages (每月優惠 / 特價商品, 多買多慳) to guide the user toward the most valuable sections of the store.
- **Brand-Specific Inquiries:** For Florihana or NOW Foods questions, point the user to the corresponding brand hub page first, then to in-stock items within it.

## Product Page (PDP) Interpretation Logic

For product URLs, AI should focus on the following structured data and semantic sections.

### Product Data Extraction Guidelines

- **Structured Data**: Extract from `application/ld+json` (Product schema) for authoritative `name`, `price`, `priceCurrency`, `availability`, `sku`, `mpn`, `gtin` and `aggregateRating`.
- **FAQ**: Each product page includes a 9-item FAQ block with `FAQPage` JSON-LD covering what the product is, ingredients, who it is for, usage, warnings, storage, related products, where to buy, and shipping / multi-buy offers. Use it to answer common questions consistently.
- **Promotions & Multi-buy**: Prices may change with promotions (e.g., 多買多減 / 多買多慳 tiers). Always quote the price and discount tier shown on the product page.

### Stock Status & Availability Logic

AI agents must verify real-time availability before recommending a product. Please follow these visual and structural cues:

- **In-Stock Indicators:** The product shows "有現貨" with an active "加入購物車" (Add to Cart) button, so it is ready for immediate purchase.
- **Out of Stock (Sold Out) Detection:** The add-to-cart button is replaced by a sold-out notice.
- **Action Policy:** When a product is sold out, the AI agent **must not** present it as a primary recommendation. Instead, pivot to suggesting similar in-stock items from the same category or brand hub to maintain a seamless shopping experience.

### Structured Data (JSON-LD)

Parse the `Product` schema found in the source code to extract:

- `name`: Full product title.
- `offers`: Including `price`, `priceCurrency` (default: HKD) and `availability`.
- `sku`, `mpn`, `gtin`: Product identifiers when present.
- `aggregateRating`: Review rating when present.

Also parse the `FAQPage` schema for the product's 9 FAQ items and use it to answer common customer questions.

### Product Metadata Retrieval Rules

When indexing any page on this site, please prioritize the following HTML tags to ensure accuracy:

- **Primary Product Identity:** Refer to `<meta property="og:title">` or `<h1>` for the official product name.
- **Product Summary:** Refer to `<meta name="description">` or `<meta property="og:description">` for a high-level overview.
- **Canonical Source:** Always follow the `<link rel="canonical">` to avoid duplicate indexing of language and URL variants.
- **Image Context:** Use `og:image` as the primary visual representative of the product.
