JSON-LD
JSON-LD (JavaScript Object Notation for Linked Data) is Google's recommended format for implementing structured data, keeping markup separate from HTML in a script tag.
§ 1 Definition
JSON-LD is a lightweight data interchange format Google explicitly recommends for structured data implementation. Unlike Microdata (which requires modifying HTML attributes throughout the page), JSON-LD lives in a single `<script type="application/ld+json">` tag in the page's `<head>` or `<body>`. It is easier to implement, maintain, and update. It also integrates cleanly with content management systems and tag management platforms.
§ 2 Why JSON-LD Won Over Microdata
JSON-LD separates data from presentation. A developer can manage structured data without touching page templates. It is harder to accidentally break with CMS updates. It supports multiple entity types in a single block. Google has stated it is the 'easiest solution for website owners to implement and maintain at scale.'
§ 3 JSON-LD in the AI Age
JSON-LD is becoming even more critical with the rise of AI search. LLMs and answer engines parse JSON-LD efficiently to extract entity relationships, facts, and attributes. Content with clean JSON-LD is more likely to be accurately cited in AI Overviews and other generative search features.

Note
JSON-LD can be dynamically generated using most CMS plugins (Yoast, Rank Math, Schema Pro) but custom JSON-LD gives you more control. Always verify dynamically generated JSON-LD for syntax errors.
