Frequently Asked Questions

What is structured data?▾
Structured data is a standardized format for providing information about a page. Search engines use it to create rich snippets (star ratings, FAQs, breadcrumbs, etc.) in search results.
What formats does this check?▾
This tool detects JSON-LD (recommended by Google) and Microdata markup. JSON-LD is the most common and preferred format.
What types of schemas are validated?▾
The tool validates common schema.org types including Organization, WebSite, Article, Product, and BreadcrumbList. It checks for required properties specific to each type.
How do I add structured data to my site?▾
Add a <script type="application/ld+json"> tag to your HTML with a JSON object following schema.org specifications. Most CMS platforms have plugins that generate this automatically.
How does this tool fetch structured data?▾
Our servers fetch the URL you provide and parse the HTML to find JSON-LD script blocks and Microdata attributes. This server-side approach ensures we see the same markup that search engine crawlers see.
What are rich snippets?▾
Rich snippets are enhanced search result listings that display extra information like star ratings, recipe times, FAQ dropdowns, or product prices. They are generated from valid structured data on your pages.
Can I check pages behind a login?▾
No. The tool can only check publicly accessible URLs. Pages behind authentication or firewalls cannot be reached by our servers.
