What is structured data and why use it?

Structured data is extra markup (usually JSON-LD) added to your HTML that helps search engines understand the context of your content.

For example, marking up a product page with Product schema enables Google to display price, availability, and reviews directly in search. This leads to rich results, higher CTR, and improved visibility.

It’s not a direct ranking factor, but enhanced presentation can significantly impact organic performance. Common schemas: FAQPage, Breadcrumb, Product, Organization, Review, Event.
