Schema Checker – Detect Schema.org Markup on Any URL

The Schema Checker gives you a fast way to see whether a page actually contains structured data and which schema.org types are in use. Instead of manually scanning the source or relying on assumptions about templates and plugins, you get a clear list of detected schema types for the URL you test.

Use it as a lightweight first step: confirm that markup exists, understand what kind of entities are marked up, and then decide whether deeper validation is needed.

What the Schema Checker does

This tool scans a page and looks specifically for schema.org-based structured data. It detects common formats such as JSON-LD, microdata and RDFa, then summarizes what it finds so you can see your implementation at a glance.

Typical insights include:

• Whether the page has any structured data at all

• Which schema types are present (for example Organization, Product, Article, BreadcrumbList, FAQPage, LocalBusiness, etc.)

• How many instances of each type exist on the page

• Whether the detected types match the actual purpose of the page

If you also use the Schema Markup Validator, you can go from “Do I have schema here?” to “Is my schema valid and complete?” in a smooth, two-step workflow.

Why schema coverage matters for SEO

Structured data is most effective when it is applied consistently across key templates. It is not enough to have schema on a handful of pages; search engines benefit from broad, reliable coverage.

Good schema coverage helps you:

• Improve eligibility for rich results across entire sections (products, articles, FAQs, events)

• Communicate page types and entities more clearly at scale

• Maintain consistent SERP appearance when you publish new content or roll out new templates

• Spot gaps where important page types still have no structured data at all

The Schema Checker makes it easy to see where you already have coverage and where you need to extend it.

What this tool helps you identify

By running important URLs through the Schema Checker, you can quickly identify:

• Pages that should have structured data but currently do not

• Templates that output the wrong schema type (for example, Article used where Product would be more appropriate)

• Inconsistent implementations where some pages of a template have schema and others do not

• Overly generic types (like Thing) that could be replaced with more specific types (Product, Service, BlogPosting, etc.)

• Pages that contain multiple schema types and may need a clearer “main entity of page”

This gives you a practical to-do list for improving the breadth and quality of your structured data implementation.

How to use the Schema Checker

1. Paste the URL you want to test into the input field.

2. Run the analysis to let the tool crawl the page and detect schema.org markup.

3. Review the list of schema types and the number of instances found on the page.

4. Compare the detected types with the actual content and purpose of the page.

5. For pages where schema is present, optionally move on to the Schema Markup Validator for a deeper error and warning check.

You can repeat this for representative URLs from each template: home, category, product, blog post, location pages, landing pages and more.

Interpreting the results

When reviewing the output, ask yourself:

• Does this page have schema at all? If not, should it?

• Are the detected schema types appropriate for the content?

• Is the main business entity or page entity clearly represented?

• Are important elements like products, FAQs, breadcrumbs or reviews missing from the schema layer?

If a high-value template has no schema, that is a strong opportunity for enhancement. If the schema type does not match the intent of the page, you may need to adjust your implementation at the template or plugin level.

Best practices for structured data coverage

Use the Schema Checker while aligning your site with structured data best practices:

• Prioritize schema for pages that can benefit from rich results: products, reviews, FAQs, articles, events, recipes, local business pages, etc.

• Use specific types rather than generic ones to help search engines understand context.

• Implement schema at the template level (themes, components, CMS layouts) so new pages are automatically covered.

• Keep site-wide entities (Organization, WebSite, BreadcrumbList) consistent across your key templates.

• After deployment, re-check a sample of URLs for each template to make sure schema is present and correctly typed.

Combining good coverage with valid, accurate markup makes your structured data strategy much more resilient over time.

When to use this tool in your workflow

The Schema Checker is particularly useful when:

• Auditing a new site, theme or redesign to see how schema is being used

• Verifying that a plugin or CMS module is actually outputting schema on live pages

• Checking templates after a migration, domain change or front-end rebuild

• Mapping out where you already have structured data and where you need to add it

• Doing quick checks during technical SEO audits without diving immediately into full validation

It works well as the first pass for coverage and type detection, with the Schema Markup Validator as the next step for detailed quality checks.

FAQ

What is the difference between Schema Checker and a Schema Validator?
The Schema Checker focuses on presence and types: it tells you whether a page has schema.org markup and which schema types are detected. A validator goes deeper into syntax, required properties, errors and warnings. Using both gives you coverage plus quality.

Do all pages need structured data?
Not necessarily, but any page that you expect to rank and that matches a supported schema type is a good candidate. Product pages, articles, FAQs, events, local businesses and reviews benefit the most.

If the Schema Checker finds schema, does that mean it is valid?
Not always. This tool confirms detection and types. You should still run important URLs through a validator to confirm that the markup is syntactically correct, complete and aligned with search engine guidelines.
