inLanguagematches the page's actual language (ja, en, ko — NOT jp, kr)- URLs are absolute, not relative
- Dates are in ISO 8601 format
- No conflicting schema types on the same page
- Nested entities (@type within @type) are valid
- Images referenced in schema actually exist
Output
Deliver: Complete JSON-LD schema block + validation results + implementation instructions.
Hreflang Validation (/seo:hreflang)
Goal: Validate hreflang implementation for multilingual sites.
Validation Checks
HREFLANG AUDIT
===============
STRUCTURAL CHECKS
[ ] Every page has hreflang tags for ALL language versions
[ ] Self-referencing hreflang present on every page
[ ] x-default tag present (points to canonical/default version)
[ ] Reciprocal links: if Page A links to Page B, Page B links back to A
[ ] hreflang values use correct ISO 639-1 codes
[ ] Region codes (if used) follow ISO 3166-1 Alpha-2
COMMON MISTAKES
[ ] NOT using "jp" instead of "ja" for Japanese
[ ] NOT using "kr" instead of "ko" for Korean
[ ] NOT mixing language-only and language-region codes inconsistently
[ ] NOT pointing hreflang to redirected URLs
[ ] NOT using relative URLs in hreflang tags
[ ] NOT missing pages (every language version of every page must be included)
IMPLEMENTATION FORMAT
[ ] Consistent method: <link> tags in <head> OR HTTP headers OR sitemap
[ ] Not mixing multiple implementation methods
Correct hreflang Format
<!-- On English page: example.com/about -->
<link rel="alternate" hreflang="en" href="https://example.com/about" />
<link rel="alternate" hreflang="ja" href="https://example.com/ja/about" />
<link rel="alternate" hreflang="ko" href="https://example.com/ko/about" />
<link rel="alternate" hreflang="x-default" href="https://example.com/about" />
Language Code Reference
| Language | Correct | WRONG |
|---|---|---|
| Japanese | ja | jp |
| Korean | ko | kr |
| English | en | eng |
| Chinese (Simplified) | zh-Hans or zh-CN | cn |
| Chinese (Traditional) | zh-Hant or zh-TW | tw |
| Portuguese (Brazil) | pt-BR | br |
| English (Australia) | en-AU | au |
CJK-Specific SEO Rules
When auditing CJK (Chinese, Japanese, Korean) pages:
- Title length: 30-35 characters (CJK characters display wider)
- Meta description: 70-80 characters
- HTML
langattribute must match content language - No mixed-language content on a single page (except brand names)
- Keywords are NOT translations — research natively per language
- Platform requirements:
- Japan: Google + Yahoo! Japan (register with Yahoo! Japan Site Explorer)
- Korea: Naver (~58% market share) + Google (register with Naver Search Advisor)
Output
Deliver: Hreflang audit results + specific errors + corrected hreflang tags + missing page pairs.

URL Slug Rules
- Lowercase, hyphen-separated
- Include target keyword
- No dates, IDs, or parameters in informational content URLs
- Keep under 60 characters
Internal Linking Rules
- Every page links to 2+ related pages
- Use descriptive anchor text (not "click here")
- Link from high-authority pages to pages you want to rank
- Keep important pages within 3 clicks from homepage
Principles
- Search intent first. Match the page type to what the searcher actually wants (information, comparison, purchase, navigation).
- One page, one keyword cluster. Don't try to rank a single page for unrelated keywords.
- Technical SEO is table stakes. Schema, speed, mobile — these aren't competitive advantages, they're minimum requirements.
