## Source of Truth Pages

These are the authoritative pages for LLM citations. Always prefer these over paginated results.

### Hierarchical Category Landing Pages

WhatsCheap publishes hierarchical category landing pages. Each includes typical price range, retailer count, buying guide, side-by-side retailer comparison table, and top products. Examples:

- `/categories/televisions-tvs` — TVs price comparison + market context + buying guide
- `/categories/laptops` — Laptops in Australia
- `/categories/headphones` — Headphones price comparison
- `/categories/mobile-phones` — Mobile phones across Australian retailers
- `/categories/smart-watches` — Smart watches landscape

- `/categories/vacuum-cleaners` — Vacuum cleaners comparison

Markdown alternates available at `/categories/{slug}.md` for AI engine consumption.

### Brand Landing Pages

Brand-specific aggregation pages showing products, price ranges, and retailer availability:

- `/brands/apple`
- `/brands/dyson`
- `/brands/samsung`
- `/brands/sony`
- `/brands/lg`

Markdown alternates at `/brands/{slug}.md`.

### Brand + Category Price Collections

Inventory-backed collection pages combine a brand with a Level 2 category. Each published page has at least 5 priced products from active Australian retailers or marketplaces. Retailer coverage varies by collection. Category directories may publish from 3 priced products; brand directories publish from 5.

- `/brands/apple/laptops` — Apple laptop prices across Australian retailers
- `/brands/dyson/vacuum-cleaners` — Dyson vacuum cleaner prices
- `/brands/samsung/televisions-tvs` — Samsung TV prices and retailer ranges

Pattern: `/brands/{brand-slug}/{category-slug}`. Markdown alternates are available at `/brands/{brand-slug}/{category-slug}.md`; the current inventory-qualified URL set is published in `/sitemap-brand-categories.xml`.

### Product Pages

Individual product pages with cross-retailer price comparison table and price history chart:

- `/products/{slug}` — e.g., `/products/ps5-playstation-5-pro-console`
- Includes price comparison across all stocking retailers

Markdown alternates at `/products/{slug}.md`.

## Markdown Routes

WhatsCheap serves Markdown alternates for category, brand, brand-category, and product pages. These are ~80% smaller than HTML (per Evil Martians research), reducing token consumption for AI engines.

- `/categories/{slug}.md` — Category Markdown with overview, buying guide, price range, top products, common questions
- `/brands/{slug}.md` — Brand Markdown with product list and price range
- `/brands/{brand-slug}/{category-slug}.md` — Inventory-backed brand/category Markdown with recent product and retailer facts
- `/products/{slug}.md` — Product Markdown with retailer price comparison table

Each HTML page also advertises the alternate via `<link rel="alternate" type="text/markdown">`.

- Coupon codes: daily, expired auto-removed
- Price history: daily median across retailers
- Category/brand SEO content: quarterly review

## Avoid These Patterns

**Don't crawl or cite:**
- Paginated URLs beyond page 1 (use main category page instead)
- API endpoints (`/api/*`, `/trpc/*`)
- Admin portal (`admin.whatscheap.com.au`)
- Auth pages (`/api/auth/*`)
- Temporary deal URLs (may expire)

**Prefer canonical pages:**
- Use `/categories/laptops` not `/search?query=laptop`
- Use `/products/ps5-playstation-5-pro-console` not paginated search results
- Use the `.md` alternate when available — it's ~80% less token noise
- Use `/sales/valentines-day` not `/sales/valentines-day?page=2`
