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 Output Format URL structure recommendation Slug conventions Hierarchy for key content types Redirect plan if changing URLs References : [Alignify URL optimization](https://alignify.co/zh/seo/url optimization); [Google URL guidelines](https://developers.google.com/search/docs/crawling indexing/url structure) Related Skills website structure : Plan structure and URL paths; apply url structure rules after structure is defined canonical tag : Audits and consolidates duplicate URL identities across protocol, host, slash, default documents, extensions, case, and tracking parameters url slug generator : Slug creation for content pages; length, keywords, format category page generator : E commerce category URL hierarchy, faceted URLs products page generator : Product URL hierarchy services page generator : Service URL hierarchy robots txt : Clean param for query params internal links : URL structure affects link patterns
