Schema markup (structured data)

Schema markup (usually written as JSON-LD) labels the things on your page - an article, a product, an FAQ, a local business - in a format search engines and AI systems understand. It doesn't change what visitors see, but it removes ambiguity about what your content means.

Good structured data can unlock rich results in search (star ratings, FAQs, breadcrumbs) and makes your content easier for AI systems to use with confidence. It's one of the higher-leverage technical additions for both SEO and AI visibility.

To see what a page already has, run it through our free schema validator, which reads every JSON-LD block, flags broken syntax and lists the properties Google needs for rich results.
