What this means in practice
Structured data is a machine-readable description of page entities and content. It supports understanding and feature eligibility where search engines support the markup.
Implementation path
- Select supported types that match the visible page and its actual purpose.
- Use stable identifiers and accurate properties when the schema vocabulary supports them.
- Validate markup and inspect the rendered source after template changes.
- Treat rich-result eligibility as conditional; valid markup does not guarantee a search feature.
What good looks like
A strong implementation makes the intended behavior obvious to a visitor, a crawler, and a machine reader. It has one clear purpose, uses consistent signals, and does not rely on hidden assumptions.
