name: url-structure
description: When the user wants to optimize URL structure, fix URL issues, or plan URL hierarchy. Also use when the user mentions "URL structure," "URL optimization," "slug," "clean URLs," "URL hierarchy," "URL path," "permalink structure," "URL best practices," "dynamic URLs," or "URL parameters." For per-page slug wording, use url-slug-generator. For canonical consolidation, use canonical-tag.

# SEO On-Page: URL Structure

Guides URL structure optimization for SEO: readability, hierarchy, and best practices.

**When invoking**: On **first use**, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On **subsequent use** or when the user asks to skip, go directly to the main output.

## Scope (On-Page SEO)

- **URL hierarchy**: Path structure, categories, depth
- **URL format**: Static vs dynamic; omit file extensions
- **URL slug**: See **url-slug-generator** for slug creation (3–5 words, under 60 chars)
- **Duplicate variants**: Route protocol, host, slash, default-document, extension, case, and tracking variants to **canonical-tag**

## Initial Assessment

**Project context:** Read root `contextus.md` when present and load only the modules relevant to this task. Without Contextus, use available project material or user-provided facts and ask for missing information; do not create a parallel context system.

Identify:
1. **Site structure**: Categories, subcategories, content types
2. **Current URLs**: Existing patterns and issues
3. **Multi-language**: URL structure for zh/en (e.g., /zh/, /en/ or subdomains)

## Best Practices

### URL Guidelines

| Principle | Guideline |
|-----------|-----------|
| **Readable** | Use words, not IDs; `/blog/seo-guide` not `/p/12345` |
| **Short** | Shorter is generally better; avoid unnecessary depth |
| **Keyword** | Include target keyword when natural |
| **Lowercase** | Use lowercase; avoid mixed case |
| **Hyphens** | Use hyphens to separate words: `seo-guide` |
| **Avoid** | Special chars, query params for core content, session IDs |

### Hierarchy

| Pattern | Example | Use |
|---------|---------|-----|
| **Flat** | `/page-name` | Simple sites |
| **Category** | `/blog/post-name`, `/tools/tool-name` | Content sites |
| **Nested** | `/category/subcategory/page` | Deep hierarchies (keep shallow) |

### Multi-language

| Pattern | Example |
|---------|---------|
| **Path prefix** | `/zh/page`, `/en/page` |
| **Subdomain** | `zh.example.com`, `en.example.com` |
| **ccTLD** | `example.cn`, `example.com` |

### Static vs Dynamic vs Pseudo-Static URLs

| Type | Example | Use |
|------|---------|-----|
| **Static** | `/blog/seo-guide` | Direct file; best SEO; content stable |
| **Dynamic** | `/product?id=123` | Program-generated; avoid for indexable content |
| **Pseudo-static** | `/blog/seo-guide` (rewritten from `.php`) | Combines both; common in CMS |
| **Rule** | Prefer static or pseudo-static; if dynamic, keep params ≤2; use **canonical-tag** and **robots-txt** (Clean-param) |

### File Extensions

- **Omit** `.html`, `.php`, `.aspx` — keeps URLs technology-agnostic, shorter, easier to refactor
- **Example**: `/seo-guide` not `/seo-guide.html`

### URL Parameter Boundary

Use parameters only when they represent a real function. Route duplicate-page decisions for UTM, tracking, sorting, filtering, sessions, and other parameter variants to **canonical-tag**; do not assume every parameterized URL should canonicalize to the base page.

### Use Cases

| Scenario | Focus |
|----------|-------|
| **New site** | Plan hierarchy upfront; avoid later restructuring |
| **Migration** | 301 mapping; canonical; see **canonical-tag** |
| **Large site** | Dynamic URLs, params, multi-language — canonical + robots |
| **SEO audit** | Check structure, params, canonical consistency |

## Common Issues

| Issue | Fix |
|-------|-----|
| Long URLs | Shorten; remove redundant words |
| Dynamic params | Decide whether they change page identity; use **canonical-tag** for duplicate variants |
| Mixed case | Prefer lowercase for new URLs; use **canonical-tag** before consolidating existing routes |
| Changed URLs | 301 redirect old to new |
