Structured data
Information on a page in a machine-readable form, such as markup, tables or JSON fields.
What it means
Structured data is information that a program can read without guessing at layout. Examples include schema.org markup embedded in a page, tables, JSON feeds and fields in a database. Search APIs that return structured fields let your code filter, sort and join results, instead of parsing free text.
Many web pages carry some structure, but it is uneven. A product page might mark up its price while a report uses a plain table. Search APIs differ in whether they expose these fields, and some return only the visible text. When your app needs dates, prices or identifiers, check whether the API returns them as fields, and test on a sample of the pages you care about. Structured fields also make results easier to test, because you can compare a date or a price directly instead of reading two paragraphs of text.
