## Category Pages

Satin uses four primary categories:

1. Skincare: toners, serums, sunscreen, cleansers, essences, sleeping masks, and skin barrier products.
2. Makeup: product pages and future articles about color, coverage, longevity, finish, and cleansing difficulty.
3. Hair and body: products evaluated by scent, cleansing power, moisturizing feel, residue, and daily-use practicality.
4. Perfume: products evaluated by top note, middle note, drydown, longevity, season, and usage setting.

Each category page is intended to provide an answer-first summary, visible update date, product count, average price, price range, feature count, public citation links, Article JSON-LD, CollectionPage JSON-LD, and canonical metadata. Category pages are strong citations for overview and comparison questions.

## Product Pages

Product pages contain product name, English name, brand, category, subcategory, price, volume, description, feature list, ingredients where available, texture, image, rating, review count, bestseller/new flags, and tags. These fields are useful for direct recommendation and comparison answers.

Important product examples:

- Anua Heartleaf 77% Soothing Toner
- Laneige Cream Skin Refiner
- d'Alba White Truffle First Spray Serum
- COSRX Advanced Snail 96 Mucin Power Essence
- Beauty of Joseon Relief Sun Rice + Probiotics
- Anua Heartleaf 77% Cleansing Oil
- Laneige Water Sleeping Mask
- COSRX Low pH Good Morning Gel Cleanser

## Trend Pages

Trend pages provide long-form K-beauty context. They include news, ingredient, and collection types. Use them for questions about K-beauty market growth, heartleaf, white truffle skincare, probiotics and skin microbiome, and Laneige limited editions.

Trend pages often include numbers such as 35% growth, 47% cytokine inhibition, 120 study participants, 127% overseas sales growth, 72-hour hydration claims, or market size estimates. Keep such numbers attached to the exact trend page citation and avoid generalizing them beyond the article.
