  - Curated /search collections (category pages, brand pages, and whitelisted SEO filter pages)
- /sitemap-sellers.xml
  - Seller directory + seller landing pages: /shopdispensary and /search?sellers={Seller-Slug}
- /sitemap-products.xml (and possibly /sitemap-products-2.xml, /sitemap-products-3.xml, ...)

- /sitemap-news.xml

## What to crawl (highest value)
- URLs listed in the sitemap index and its component sitemaps
- Product detail pages and curated collection pages
- Blog/help/news editorial pages
- Location and seller pages

## Canonicalization and deduplication (important on Chow420)
- Prefer sitemap-listed URLs as canonical.
- Normalize host to https://www.chow420.com.
- Respect on-page <link rel="canonical"> and <meta name="robots">.
- Strip non-content tracking parameters: utm_*, gclid, fbclid, msclkid, ref.

## /search URLs (critical rules)
- Do not brute-force enumerate arbitrary filter combinations.
- Only treat a /search query as canonical when it is explicitly included in the sitemap index.
- The sitemap generator whitelists /search combinations from the SEO filter registry:
  - Registry source: resources/data/seo_filter_pages.php
  - Canonical query ordering is defined per page via canonical_order; preserve that order when generating canonical URLs.
- Common canonical /search patterns used by the generator include:
  - /search?view_all_flag=1
  - /search?filterby_price_drop=true&view_all_flag=1
  - /search?best_seller=true&view_all_flag=1
  - /search?chows_choice=true&view_all_flag=1
  - /search?featured=true&view_all_flag=1
  - /search?brands={BrandId}&view_all_flag=1
  - /search?category_id={CategorySlug}&view_all_flag=1
  - /search?sellers={Seller-Slug}

## Helpcenter URL notes
- Category/question slugs may be “spaces to hyphens” (not a strict slugification); treat sitemap URLs as authoritative.
- You may see multiple valid helpcenter URL shapes (category lists, details pages with base64 ids).

## Please avoid (private, personalized, or low-value)
- Account/auth/checkout/cart flows:
  - /login, /signup, /signup_buyer, /signup_seller, /my_bag
- Personalized/recommendation endpoints:
  - /get_all_recently_view_products, /picks_for_you
- User uploads and binaries:
  - /uploads/

## Fetch etiquette
- Be respectful with concurrency and re-fetch frequency.
- Prefer sitemap-driven crawling and cache after canonicalization.
