JSON-LD
Definition
JSON-LD stands for JavaScript Object Notation for Linked Data—the preferred format for declaring structured data that AI systems can interpret. JSON-LD embeds machine-readable entity definitions and relationships within web pages without affecting visual presentation.
JSON-LD separates structured data from HTML content, placing machine-readable information in script tags that browsers ignore visually but AI systems process directly. This separation allows comprehensive entity definition without cluttering human-facing content, making it the industry standard for GEO implementation.
Why This Matters
Choosing the right structured data format affects implementation simplicity and AI comprehension accuracy. JSON-LD is recommended by Google, supported by all major AI systems, and easiest to maintain because it does not interleave with HTML. It represents the clearest path to machine-readable expertise.
Common Misconceptions
JSON-LD requires programming knowledge.
While JSON-LD is technically code, its structure is straightforward and many tools generate it automatically. Understanding the concepts matters more than coding ability.
JSON-LD only affects Google search results.
JSON-LD benefits all systems that process structured data, including ChatGPT, Claude, Perplexity, and other AI systems. Its value extends far beyond Google rich snippets.
All JSON-LD implementations are equally effective.
Quality matters. Accurate, comprehensive JSON-LD that reflects genuine expertise creates better outcomes than minimal or inaccurate implementations that merely check technical boxes.
Frequently Asked Questions
Where does JSON-LD go on a webpage?
JSON-LD is placed within script tags in the HTML head or body. It does not display visually but is readable by AI systems and search engines that process the page.
How do I validate my JSON-LD?
Use the Schema.org Validator for structural correctness and Google Rich Results Test for Google-specific validation. For AI visibility, also test by asking AI systems about your content.
Can I have multiple JSON-LD blocks on one page?
Yes. Complex pages often have multiple JSON-LD blocks representing different entities and their relationships. These can be separate blocks or combined using the @graph property.
