FAQPage Schema
How do I add JSON-LD structured data to a webpage for rich results?▼

You add JSON-LD structured data by inserting a script tag with valid schema.org properties into your page head, using complete examples for types like Organization, Article, or Product to enable rich results.

What is the best way to combine multiple schema.org types on a single page?▼

The best way to combine multiple schema.org types on a single page is using @graph combinations, which let you nest multiple structured data entities like Organization and WebSite within one JSON-LD script block.

Does JSON-LD schema markup work with React and Next.js applications?▼

Yes, JSON-LD schema markup works with React and Next.js applications through specific implementation patterns designed for single-page apps, ensuring structured data renders correctly in the page head for search engines.

How do I validate schema markup for Google rich results eligibility?▼

You validate schema markup for Google rich results eligibility by testing your JSON-LD output in the Google Rich Results Test and schema.org validator, then monitoring performance and resolving errors through Search Console.

Why does my structured data show warnings in the Rich Results Test?▼

Structured data shows warnings in the Rich Results Test when your JSON-LD is missing recommended properties for its schema.org type, meaning you must add required fields per Google guidelines to remove errors and achieve full eligibility.
