What is structured data?

Structured data is a standardized format for providing information about a page and classifying its content. Using schema.org vocabulary with JSON-LD, you can explicitly tell search engines what your content means — not just what it says.

What is JSON-LD and why is it recommended?

JSON-LD is Google's recommended format for structured data. It is placed in a script tag, keeping it separate from HTML markup, making it easier to implement, debug, and update.

What are required vs recommended properties?

Required properties are the minimum fields Google needs to process and potentially display a rich result. Missing required properties disqualifies a page from rich results entirely. Recommended properties are optional but increase the richness and accuracy of the result shown.
