Schema App vs Schema Markup Validator (2026): which should you pick?

Pick Schema App if

• Fits if you run an enterprise site with thousands of product, blog or location pages to mark up
• Makes sense if you want an outside team to manage your structured data rather than doing it in-house

Look elsewhere if

• Not for you if you want to see a price first, as every contract is a quote from a sales call
• Skip it if you want to try it, as there's no trial and contracts run at least 12 months
• Watch out: the platform isn't sold on its own to new customers, and an hour a month of paid support is part of every contract
• Pricey if a customer-facing chatbot calls its MCP server a lot, at $100 per 100,000 requests past the first 100,000 a month
• Watch out: there's a one-time strategy and setup fee on top, and Entity Hub is an add-on

Pick Schema Markup Validator if

• Fits if you're a developer checking that schema.org markup is well formed
• Works for sites using structured data for engines and apps other than Google

Look elsewhere if

• Skip it if you want to know about Google rich results, which need Google's Rich Results Test
• Too light for a whole site, as it checks one URL or snippet per run
• Not for you if you want saved history or scheduled checks, as the page offers neither
• Watch out: it's hosted by the schema.org community project, not a company selling support

Schema App

• No prices are published: every contract is a custom quote, plus a one-time strategy and setup fee.
• Contracts run for at least 12 months, and there is no free trial.
• The platform is no longer sold on its own to new customers; at least 1 hour a month of paid support is part of every contract.
• Customer-facing chatbot use of the MCP server includes 100,000 requests a month, then costs $100 per 100,000; Entity Hub is an add-on.

Schema Markup Validator

• Does not tell you whether a page qualifies for Google rich results; Google's Rich Results Test does that.
• Tests one URL or one snippet per run; the page offers no site crawl, scheduling or saved history.
• Hosted by the schema.org project, a community effort founded by Google, Microsoft, Yahoo and Yandex, not a company selling support.

Schema App

Schema App Editor

Creates schema markup for individual pages by filling in forms, with no code to write, and manages it in one place.

Schema App Highlighter

Writes markup once for a page template, such as product, blog or location pages, and deploys it to thousands of matching pages and languages.

Deployment without IT

Pushes markup through plugins for Adobe Experience Manager, Drupal, WordPress and Shopify, a Cloudflare or Akamai function, or a tag manager.

Content knowledge graph

Links the entities in your markup to each other and to outside knowledge bases, and gathers them into an RDF knowledge graph you can reuse.

Schema Performance Analytics

Reports clicks, impressions and rich results from Search Console by page, query and markup template, without Search Console's 1,000-row export limit.

MCP server

Exposes the knowledge graph to AI tools such as ChatGPT, Gemini and Copilot Studio; use inside your own organization is included.

Schema Markup Validator

Fetch a URL

Enter a page address and the validator fetches the page and checks the structured data embedded in it.

Test a code snippet

Paste markup into the editor to check it before it is published, and rerun the test after each change.

Any schema.org type

Checks syntax and compliance with schema.org standards for every type in the vocabulary, not only the ones Google uses for rich results.

No Google-specific warnings

Google describes it as validating schema.org data without Google feature-specific warnings, which its Rich Results Test covers instead.

Interface in many languages

The validator's interface can be switched between dozens of languages, including Japanese, German, Hindi, Arabic and Spanish.

Schema App
