Does Generative AI Use Structured Data for Results

In SEO circles, a heated debate has been brewing on whether or not structured data affects rankings in AI-powered search engines.
Some SEOs suggest that adding structured data can influence the outputs of large language models (LLMs) like ChatGPT or Gemini.
But is this claim grounded in fact, or just a misinterpretation of how AI search works?
LinkedIn Sparks a Schema Showdown
Patrick Stox, a notable SEO expert, questioned the validity of these claims in a viral LinkedIn post. Stox’s query—“Why do SEOs think schema markup will impact LLM output?”—set off a flurry of discussions.
Structured data is a standardized way to describe information on a webpage, making it easier for search engines to understand and display it in rich snippets, FAQs, and knowledge panels. But its role in generative AI, like large language models (LLMs), is less straightforward.
Generative AI tools, such as ChatGPT and Google’s SGE, primarily rely on vast datasets—including web content, books, and government records—to generate responses.
While structured data helps traditional search engines enhance results, its role in AI-generated outputs is more indirect.
The Confusion: How Did We Get Here?
The myth about structured data’s role in AI search seems to stem from miscommunication.
SEO expert Jono Alderson once proposed that structured data could help AI systems better understand web content. This idea, speculative at best, morphed into a belief that structured data already influences AI rankings—a classic game of telephone within the SEO community.
Adding to the confusion, SEOs often conflate traditional search practices with AI search functionality. This has led to wasted efforts on strategies that have no measurable impact.
Lessons from SEO’s Past Missteps
The structured data debate highlights a recurring issue in SEO: chasing trends without fully understanding them.
In the past, practices like keyword stuffing and excessive link-building were widely adopted despite their lack of long-term effectiveness. Today, similar misconceptions surround concepts like structured data and EEAT (Expertise, Authoritativeness, Trustworthiness).
Patrick Stox and other industry veterans emphasize the importance of pragmatic SEO. Strategies based on speculation often waste resources and detract from proven methods, like creating high-quality, relevant content.
The Role of Structured Data in Generative AI
While structured data may not directly influence AI rankings, it does play an important supporting role in enhancing generative AI’s understanding and outputs. Here’s how:
Improving AI’s Contextual Understanding: Structured data, such as Schema.org markup, allows AI systems to differentiate between entities. For example, Google’s Search Generative Experience (SGE) uses structured data to identify key product attributes like brand, price, and reviews. This ensures that AI-generated summaries are accurate and contextually rich.
Feeding Knowledge Graphs: Generative AI models rely on knowledge graphs that aggregate structured information. Bing Chat, for instance, uses Schema.org data to enhance its knowledge panels, offering concise and reliable facts about businesses, people, or places.
Applications in Retrieval-Augmented Generation (RAG): AI setups like RAG query structured data within knowledge bases to retrieve accurate information. This grounding process ensures consistency and reliability in the model’s responses.
Content Generation Tools: Platforms like Jasper and HubSpot’s AI content assistant can parse structured data to generate accurate product descriptions, FAQs, or summaries—leveraging entities such as “product name” or “brand” from Schema.org markup.
Challenges and Limitations of Structured Data in AI
Despite its benefits, using structured data in generative AI comes with challenges:
- Parsing Issues: Not all generative AI models can parse Schema.org markup or JSON-LD without preprocessing. This may require additional steps to prepare structured data for AI use.
- Quality of Implementation: If Schema.org markup is improperly implemented—for example, with missing fields or outdated schema types—AI systems may misinterpret the data or ignore it entirely.
- Model-Specific Behavior: Some AI systems primarily train on large text corpora and may not inherently prioritize structured data unless explicitly fine-tuned for it.
Best Practices for SEOs
Here’s how to make the most of structured data while avoiding common pitfalls:
- Use Schema Where It Matters: Focus on enhancing traditional search features like rich snippets and FAQs.
- Optimize for Knowledge Graphs: Ensure your structured data is clean, complete, and properly implemented.
- Experiment Strategically: Test how structured data impacts your site’s visibility in tools like Bing Chat or SGE.
- Stay Evidence-Based: Avoid speculative strategies and rely on proven SEO practices.
The Bottom Line
Generative AI tools like ChatGPT do not directly use structured data to rank or generate responses. However, structured data indirectly enhances AI’s outputs by feeding knowledge graphs, enriching search results, and supporting retrieval-based systems. SEOs should embrace structured data’s strengths while maintaining a realistic understanding of its role in the AI ecosystem.
Key Takeaways
- AI search engines don’t directly use Schema.org to rank content, but it supports other processes.
- Structured data aids tools like Google SGE and Bing Chat by enriching responses through knowledge graphs.
- Misunderstandings about structured data’s role can lead to wasted effort; focus on proven strategies.
- Schema.org is vital for enabling rich snippets, FAQs, and features that enhance visibility in traditional search.
- Use structured data strategically and rely on research-backed methods to guide your SEO practices.
