Structured data is a way to label and organize the information on your webpages so machines (and AI) can understand it. Google defines it as “a standardized format for providing information about a page and classifying the page content”developers.google.com. In practice, structured data uses vocabularies like Schema.org and formats like JSON-LD to annotate key elements of your content. For example, on a recipe page you might mark up ingredients and cook time; on a blog you might mark up the author and publish date. Common schema types include FAQPage (for question-and-answer content), HowTo (step-by-step guides), Product (with nested Offer and Review data for e-commerce), Review (for ratings), Article/NewsArticle, and Organization (company info). Implementing these schemas makes your page’s purpose explicit to crawlers. While structured data itself isn’t a direct ranking factor, it helps search engines—and the AI systems built on them—understand and surface your content better. Schema.org provides a repository of accepted schemas, with common types including:
- FAQPage – marks up lists of questions and answers.
- HowTo – annotates instructional steps or tutorials.
- Product (+ Offer, Review) – highlights product details (name, price, availability, ratings) for shopping results.
- Review – marks up ratings and reviews of products or services.
- Organization – provides business or brand details (name, logo, contact).
- Article/NewsArticle – labels blog posts or news content (headline, author, date).
- Event – (extra) for events with dates and locations.
- LocalBusiness – (extra) for physical businesses with address and hours.
Using JSON-LD (Google’s preferred format) and including schema in your HTML tells search crawlers exactly what each piece of content means. Properly implemented schema can generate rich results (like stars, carousels, or FAQ drop-downs) and even Knowledge Panels that improve visibility. In short, structured data is how you explicitly signal page content to search engines, laying the groundwork for both traditional rich results and AI-driven answers.
How Structured Data Enhances AI Visibility
As AI features (like Google’s AI Overviews, ChatGPT, or engines such as Claude) emerge, structured data could have the potential to play a key role in helping those systems find and use your content. Google’s documentation notes that AI Overviews pull information from “a range of sources, including information from across the web. In practice, this means if your content is indexed and understandable, it can be surfaced in generative answers. Google advises no special markup is needed – just follow normal SEO guidelines– but schema gives extra clarity. It feeds the knowledge-graph and context layers that AI relies on.
In sum, while an AI search engine won’t “parse” your JSON-LD to form its answer word-for-word, schema makes your content more digestible to search crawlers and knowledge graphs. That, in turn, has potential to increase the chance your information will be included or cited by AI overviews and answer engines.
Best Practices for Implementing Structured Data
For implementing structured data as part of your AI search strategy, consider the following:
- Use JSON-LD: Google recommends JSON-LD placed in a
- Choose Relevant Schema: Only apply schemas that match the page content. For example, use FAQPage on actual FAQ pages or HowTo on step-by-step guides. Avoid marketing up irrelevant content.
- Validate Your Markup: BrightEdge’s SearchIQ can help ensure your schema is detectable and competitive with websites that rank for similar keywords.
- Focus on Evergreen Types: Key types like Article, Product/Offer/Review, FAQPage, HowTo, and Organization are widely used and recommended for content visibility.
- Don’t Overdo It: Use schema “liberally” where it adds clarity, but avoid excess. Google’s John Mueller even cautions against schema bloat on things like product pages. Only markup what truly helps explain the content.
- Leverage SEO Tools: Tools can reveal where to focus. For instance, BrightEdge’s SearchIQ analyzes the top-ranked pages in your space and highlights which schema types they use. This helps you prioritize the most impactful markups. Similarly, BrightEdge’s Data Cube X can surface emerging queries or AI-related trends. Use it to find content gaps and new opportunities to apply relevant schema (e.g. rising how-to topics or FAQs).
- Monitor and Audit: Regularly crawl your site (using technologies like ContentIQ) to ensure your structured data remains intact and error-free after any updates. Update schemas when content changes (e.g., new product attributes, post authorship, etc.).
By following these practices, you ensure that your content is both technically sound for search crawlers and semantically clear for AI engines. In the AI era, well-structured markup is a signal that helps your pages stand out in new search experiences.
The Impact of Structured Data on SEO
Structured data has long boosted traditional SEO, and that impact continues. The most obvious effect is enhanced listings in search results. Pages with proper schema can appear with rich snippets: review stars, pricing info, FAQ expanders, breadcrumbs, and more.
Moreover, schema is critical for voice, image, and other modern search channels. Voice assistants and visual search tools rely on structured cues. For example, marking up FAQ content can enable answers read aloud by smart speakers.
Even beyond clicks, structured data bolsters site authority in Google’s knowledge graph. Content marked up as an Organization, Person, or Entity can feed Google’s backend understanding of your brand. Consistent schema use (across your website and external data sources) strengthens how the web knows your entities. In turn, that can influence AI-driven panels and answers.
Structured Data and AI Technologies
Different AI-powered search tools interact with structured data in different ways:
- AI Overviews: Google’s AI snapshots pull in content from indexed pages and Google’s Knowledge Graph. The official guidance is that links in overviews are chosen automatically. However, schema still helps. Pages marked up clearly are easier for Google to parse into its knowledge graph, making them more likely to be cited as sources. In practice, FAQ and HowTo markup have become popular for AI because they directly answer questions.
- ChatGPT Search / SearchGPT (OpenAI): This AI search often uses Bing’s index as its source. That means your Bing-indexed pages (with schema) are potential sources. One report notes you should ensure Bing is crawling your site – ChatGPT Search will cite even lower-ranked pages if they’re well-structured. Structured data here serves the same purpose as in traditional SEO: making your content authoritative and easy to digest.
- Perplexity AI: Perplexity is a generative Q&A engine that cites web sources in its answers. While it hasn’t released official SEO guidelines, it clearly relies on quality web content. Schema can help Perplexity’s algorithms quickly identify answers: e.g., a Product schema immediately flags where the price and review are. The general advice is the same – great content + clear structure means better chances of being cited by Perplexity or similar tools.
- Anthropic Claude: In early 2025, Claude introduced web search. That means Claude (when web-enabled) will pull real-time info from indexed sites. Again, the fundamentals apply: structured, high-quality content is more likely to be used. Claude even provides direct citations in its responses once it finds your content.
In all cases, the common thread is that AI tools are consuming the content you publish, and they prefer content that is clear, authoritative, and well-annotated. SEO best practices – such as high domain authority, expert-written content, and strong internal/external links – still matter tremendously for AI visibility. Structured data is one more piece of that puzzle.
Looking Ahead: The Future of Structured Data in AI
The trend is clear: structured data adoption is growing as AI search matures. We expect structured data markup to expand its vocabulary further to accommodate AI needs.
Crucially, structured data is becoming part of the semantic layer that underpins AI. As generative models demand verifiable facts, clear schema provides the grounding they need. SEO leaders have noted that investing in structured data today is “not just about SEO anymore – it’s about building the semantic layer that enables AI. “In other words, schema turns your site into a machine-readable knowledge graph, and future AI tools will rely on that graph to answer questions accurately.
For digital marketers, this means structured data will remain a priority. Watch for new schema types (e.g., QAPage, Speakable, or sector-specific schemas) and ensure content is marked up accordingly. At the same time, keep core SEO strong: rich content, good UX, and technical hygiene (like open crawl paths for AI bots).
Schema and structured data remain an adjacent factor in driving visibility in both AI and traditional rankings. For marketers who need to reach customers in both of these facets, it’s critical that structured data is part of your approach to SEO.
