# Book Metadata SEO — E-Book Metadata SEO Methodology

Specialized knowledge used by the metadata-manager agent when configuring metadata and distribution settings.

## Why Metadata SEO

Over **70% of how readers discover books** in online bookstores is through search and recommendation algorithms. Metadata is the only means of telling the algorithm "who this book is for."

## Book Classification Systems

### BISAC (Book Industry Standards and Communications)

US/international standard. Domestic bookstores like Kyobo and Aladin also reference it.

| Main Category | Popular Subcategories | Code Example |
|--------------|--------------------|-------------|
| BUSINESS | Small Business, Leadership, Marketing | BUS060000 |
| SELF-HELP | Personal Growth, Motivational | SEL027000 |
| COMPUTERS | Programming, AI | COM051300 |
| FICTION | Literary, Thriller, Romance | FIC019000 |

**Selection Rule**: Maximum 3, prioritize the most specific category

### KDC (Korean Decimal Classification)

Standard for domestic libraries and bookstores.

| Main Category | Number |
|--------------|--------|
| General Works | 000 |
| Philosophy | 100 |
| Religion | 200 |
| Social Sciences | 300 |
| Natural Sciences | 400 |
| Technology | 500 |
| Arts | 600 |
| Language | 700 |
| Literature | 800 |
| History | 900 |

## Keyword Optimization Strategy

### Keyword Selection Process
