Our validator checks 16 of the most common schema types used for Google rich results. Each type is validated against Google's specific requirements. For example, adding Product schema to an e-commerce page can display the price ($29.99), rating (4.8/5), and stock status directly in Google search results.

Schema markup (structured data) helps search engines understand your content beyond just the text on the page. When implemented correctly, it can trigger rich results in Google — enhanced search listings with star ratings, prices, FAQ dropdowns, recipe cards, and more. According to Google's own documentation, JSON-LD is the recommended format for structured data implementation.
According to Search Engine Land, pages with rich results earn 20-30% higher click-through rates compared to standard blue links (2024). A Milestone Research study (2024) found that pages with schema markup rank an average of 4 positions higher than those without. JSON-LD is Google's preferred format for structured data because it's cleanly separated from HTML and easy to maintain.
"Structured data is one of the few things in SEO where Google explicitly tells you what they want. If you're not using schema markup, you're leaving visibility on the table."
— John Mueller, Google Search Advocate
For example, a LocalBusiness schema with NAP (Name, Address, Phone) data can trigger a Google Knowledge Panel with your business hours, reviews, and directions. In our testing, we've found that sites adding FAQPage schema typically see FAQ dropdowns appear in search results within 2-4 weeks.
We built this validator to check both required and recommended properties for each schema type, flagging issues that could prevent your rich results from appearing. For automated schema generation on WordPress, SEObolt Pro generates schema markup for every post and page.
SEObolt Pro generates 63+ schema templates automatically for your WordPress pages. Article, Product, FAQ, HowTo, LocalBusiness, and more - without writing a single line of code.

Schema markup is structured data you add to your website's HTML that helps search engines understand your content. It uses a standardized vocabulary from Schema.org to describe things like articles, products, events, and businesses. When search engines understand your content better, they can display rich results like star ratings, FAQ dropdowns, and product prices directly in search results, which can significantly increase your click-through rate.
JSON-LD (JavaScript Object Notation for Linked Data) is Google's recommended format for implementing schema markup. Unlike Microdata or RDFa which require modifying your HTML elements, JSON-LD is added as a separate script block that doesn't affect your page layout. This makes it easier to add, maintain, and debug structured data without touching your existing HTML code. It's also easier to generate dynamically with JavaScript or server-side code.
Schema markup helps SEO by enabling rich results (also called rich snippets) in Google search. These enhanced listings can include star ratings, prices, FAQ accordions, how-to steps, recipe details, and more. Rich results typically have higher click-through rates than standard listings. While schema markup isn't a direct ranking factor, the improved visibility and CTR can indirectly boost your organic traffic. Google also uses structured data to better understand page content for Knowledge Panels and voice search answers.
The most impactful schema types for SEO are: FAQPage (FAQ dropdowns in search results), HowTo (step-by-step instructions with images), Product (prices, ratings, availability), Article/BlogPosting (authorship and publish dates), LocalBusiness (business info in Knowledge Panel), BreadcrumbList (breadcrumb navigation in search results), and VideoObject (video thumbnails). The best types for your site depend on your content - an e-commerce site benefits most from Product schema, while a local business needs LocalBusiness and Organization schema.
Yes, this schema markup validator is completely free to use with no registration required. You can check any public URL for JSON-LD structured data or paste your JSON-LD code directly for validation. The tool checks JSON syntax, validates required properties per schema type, and provides actionable recommendations to improve your structured data for Google rich results.
