Fill in the blank: The recommended format for adding structured data to your web pages is called __________.

JSON-LD (JavaScript Object Notation for Linked Data) is the recommended format by Google for implementing structured data on web pages. It's an easy-to-use, lightweight data interchange format that can be embedded directly into the HTML of a page or dynamically injected. This allows search engines to easily understand the content and context of a page, which can lead to rich results in search. While schema.org is the vocabulary used to define structured data types (like "Product" or "Recipe"), it's not a format itself. Rich results code is a general term for the code that enables rich results, but JSON-LD is the specific, preferred format. FAQPage markup is a specific type of structured data, not the overarching recommended format.
