Structured data rules
CIPWE validates JSON-LD presence, schema type quality, and rich intent fit.
- jsonld-presence
- jsonld-valid-type
- faq-schema
- article-product-schema
Semantic and metadata rules
Markup quality directly affects parsing quality for AI systems.
- single-h1, heading-hierarchy, has-main, has-article-section
- has-title, has-meta-description, has-opengraph
Crawl and agent signal rules
These checks evaluate machine discoverability and explicit AI directives.
- has-robots, has-sitemap, has-canonical
- has-llms-txt, has-structured-summary
Rule triage model
A simple triage model helps teams coordinate implementation quickly.
- Critical: blocking discoverability or structured parsing
- Important: quality and clarity improvements
- Nice-to-have: incremental trust and consistency gains
Ownership mapping
Assign each rule category to clear owners.
- Platform engineering: crawl + infrastructure signals
- Frontend engineering: semantic + metadata rules
- Content team: clarity + schema intent
