Structured data at a glance

Structured data, often called schema markup, is code added to a page that describes its content in a way machines understand: this is a product, this is a review, this is an FAQ. It uses the Schema.org vocabulary and helps search engines and AI assistants read your page accurately.

Why structured data matters for SEO and GEO

Structured data can unlock rich results in Google, such as star ratings, FAQs, and prices, which make your listing stand out. It is also central to GEO: clear structured data helps AI assistants like ChatGPT and Perplexity identify and cite your content correctly. It is one of the highest-leverage technical improvements for visibility.
