Frequently Asked Questions

Does schema markup directly improve rankings?

No, schema markup is not a direct ranking factor. However, it can indirectly improve rankings by increasing click-through rates through rich snippets, which signals relevance to search engines.

What's the best format for schema markup?

Google recommends JSON-LD (JavaScript Object Notation for Linked Data). It's easier to implement, doesn't mix with HTML, and is simpler to maintain than Microdata or RDFa alternatives.

How many schema types can I use on one page?

You can use multiple schema types on a single page. For example, a blog post might have Article schema, BreadcrumbList schema, and Organization schema—just ensure each accurately represents page content.

How do I test if my schema is working?

Use Google's Rich Results Test at search.google.com/test/rich-results. Enter your URL to see detected schema, errors, and a preview of how rich results might appear.

Can schema markup hurt my SEO?

How long until I see rich results after adding schema?
