Search engines have relied on structured data for years, but 2025’s AI-powered landscape has given JSON-LD a second life. Google’s AI Overviews, Bing’s Deep Search and generative answer engines like ChatGPT all use machine-readable data to understand entities, surface rich snippets and decide which pages are trustworthy enough to cite. If your content automation stack ships hundreds of articles without a robust JSON-LD layer, you’re leaving both classic SEO rankings and AI visibility on the table.
What Makes JSON-LD Critical for AI SEO?
-
Entity clarity: Large language models (LLMs) build knowledge graphs from web-scale corpora. Clean Schema.org objects help them disambiguate brands, products and authors.
-
Citation readiness: Generative engines reward pages that provide verifiable, structured claims (see our guide to making content cited by ChatGPT).
