What is schema markup and how does it help SEO?

Schema markup is structured data code (in JSON-LD format) added to a page's HTML that tells search engines exactly what type of content the page contains. It enables rich results in Google — star ratings, FAQs, how-to steps, event dates — which increase click-through rates by up to 30%. Schema also improves your visibility in AI-generated answers (GEO).

Which schema types have the most SEO impact?

The highest-impact schema types are: FAQPage (boosts AI visibility and earns FAQ rich results), Article/BlogPosting (enables author and date display), LocalBusiness (powers Google Maps and local pack), Product with Offers (star ratings for e-commerce), and HowTo (step-by-step rich snippets). Implement FAQPage on every informational page as a priority.

Do I need to test my schema markup?

Yes, always validate schema before deploying. Use Google's Rich Results Test (search.google.com/test/rich-results) or the Schema Markup Validator (validator.schema.org). Invalid schema — such as missing required properties or wrong value types — is ignored by Google and won't generate rich results. Test after every schema change.

What is JSON-LD and why is it the recommended format?

JSON-LD (JavaScript Object Notation for Linked Data) is Google's preferred schema format. Unlike Microdata or RDFa which require schema attributes embedded throughout your HTML, JSON-LD lives in a single <script> block in the <head>. This makes it easy to add, update and maintain without risking changes to your page's visual layout.
