In short
Machine-readable information added to a page so search engines and answer systems can understand facts, entities, relationships, and page type.
Schema markup is the common vocabulary, and JSON-LD is the common format.
Where it bites
Structured data matters when visibility depends on how machines read, cite, and summarise your pages. It rewards clear structure more than louder marketing language.
What to check
- Is the definition explicit enough to be cited?
- Does the page answer the buyer question directly?
- Is the source structure machine-readable?
