What is JSON-LD?

What is JSON-LD?

Search engines can read your content, but they cannot always understand it. A page about “Apple” might be about fruit, a technology company, or a record label. Without specific signals, algorithms have to guess. JSON-LD removes that ambiguity.

How Structured Data Powers AI Answers

JSON-LD (JavaScript Object Notation for Linked Data) is structured data—a block of code, typically placed in your page’s <head>, that describes your content using a standardized vocabulary. It tells machines not just what words appear on your page, but what those words mean.

Think of it as a translator. While your HTML displays the content to humans, JSON-LD explains the context to crawlers. Here is what that looks like in practice:

<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "Article",
  "headline": "What is JSON-LD?",
  "author": {
    "@type": "Person",
    "name": "Bridger Tower"
  }
}
</script>

This snippet tells Google: this page is an article, this is its title, and this person wrote it. No guessing required.

Why It Matters: The SEO and AEO Connection

For years, the primary argument for using JSON-LD was to generate rich results in Google Search—listings that include star ratings, prices, images, or FAQ dropdowns. These visual enhancements work; data suggests that users click on rich results 58% of the time, compared to just 41% for standard links.

However, the value of structured data has shifted. It is no longer just about standing out in a list of blue links; it is about feeding the artificial intelligence systems that synthesize answers.

Structured Data as AI Training Material

AI systems like ChatGPT, Perplexity, and Gemini increasingly scrape web content to answer user queries directly. This has given rise to SEO vs GEO (Generative Engine Optimization). When these models encounter clear, valid JSON-LD, they can extract facts with higher confidence.

If you run an e-commerce site, for example, precise Product schema increases the likelihood that a model like Gemini will accurately cite your pricing and availability when a user asks for recommendations. Without it, the AI might hallucinate details or skip your product entirely. This is a core component of modern AEO services.

Common Schema Types

Different content requires different definitions. The most effective strategies mix multiple types to create a complete picture of the entity:

  • Article or BlogPosting: Essential for news and educational content. It establishes authorship and publication dates, which are critical for E-E-A-T.
  • Product: Mandatory for e-commerce. It details price, availability, and aggregate ratings.
  • FAQPage: excellent for capturing long-tail queries and feeding direct answers to voice search assistants.
  • Organization: Defines your company logos, social profiles, and contact points.
  • Person: crucial for establishing the authority of authors and professionals, particularly in legal or medical fields.

Implementation

Adding JSON-LD is less invasive than older methods like Microdata because it does not require altering your visual HTML markup.

For developers using frameworks like Next.js, you can inject JSON-LD via a <script> tag in your layout or through the next/head component. The Schema.org documentation provides templates for nearly every scenario. If you are on WordPress, many SEO plugins handle the basics, but custom implementation is often necessary for advanced AEO strategies.

Once implemented, validation is non-negotiable. Google’s Rich Results Test will flag syntax errors that could prevent your data from being indexed.

The Future is Structured

Visibility now means more than ranking on a results page. It means being cited when an AI constructs an answer. Structured data serves both goals: it helps traditional search engines display your content richly, and it provides the raw “knowledge” that AI models need to reference you correctly.

When a model answers a question about your industry, clear schema markup increases the odds that it draws from your page—and credits you for it.

FAQ

Does JSON-LD help with rankings?

Google has stated that structured data is not a direct ranking factor. However, because it enables rich results which often have higher click-through rates, it indirectly signals to search engines that your content is valuable.

Can I use multiple schema types on one page?

Yes. It is common to nest schemas. For example, a Product page might also contain FAQPage schema and BreadcrumbList schema to provide full context.

How does JSON-LD affect AI search?

AI search engines (like Perplexity or SearchGPT) rely on structured data to parse facts quickly. Clear schema helps these engines understand the relationship between entities (e.g., a product and its price), making them more likely to cite your content in generated answers.
