Free Schema Validator Tool, Test Structured Data Online

Free Tool

Schema Validator Online

Enter a page URL to auto-detect every schema block, or paste your JSON-LD directly. This schema validator tool supports Article, Product, FAQPage, LocalBusiness, Recipe, Event and 15+ more types.

This checks whether your markup is present and structurally valid. It is not Google's Rich Results Test, which answers a different question, whether Google will actually show a rich result. Valid markup does not guarantee one. Use both.

What is schema markup?

Schema markup is code you add to a page that tells search engines what the content actually means. A human reads a page and knows it is a recipe. A search engine reads HTML and sees a heading and a list. Schema names it explicitly. This is a Recipe, this is the cook time, this is the rating. A schema validator reads that code back and checks it is correct.

There are three formats. JSON-LD sits in a script tag and is what Google recommends. Microdata and RDFa are woven into your HTML attributes and are older. This tool reads all three, because plenty of sites still run them.

Schema does not improve rankings on its own. Google is explicit about that in its structured data documentation. What it does is make you eligible for rich results, and help machines understand you.

Comparison

Which structured data testing tool should you use?

Tool	The question it answers	Covers	Sign-in
This tool	Is my markup there, and is it structurally sound?	JSON-LD, Microdata, RDFa on any URL	No
Schema Markup Validator (validator.schema.org)	Is it valid against the schema.org standard?	Every schema.org type, no Google-specific checks	No
Google Rich Results Test	Can Google actually show a rich result for this?	Only the types Google supports for rich results	No
Google Search Console	Is it working across my whole site, over time?	Your verified site only	Yes
Structured Data Testing Tool	Retired	Google deprecated it and moved it to validator.schema.org	Gone

These answer different questions, which is why people get confused when one passes and another complains. Google's own advice is to start with the Rich Results Test for rich result eligibility and use the Schema Markup Validator for generic schema.org validation. Use this tool first to see what markup is on the page at all, then chain the others.

Expert Tips

Schema Best Practices from 17+ Years of SEO

⚡

Use JSON-LD Always

Google's preferred format. Place it in the <head> or <body>, doesn't require touching your HTML content.

🎯

Match Page Content

Schema markup must match the visible page content exactly. Google will penalise misleading or invisible schema that isn't reflected on the page.

A validator reports two kinds of finding, and they are not equal. An error means a required property is missing or malformed, and it can stop the markup being eligible for a rich result, so fix every error first. A warning flags a recommended property you left out, which still works but leaves value on the table, like skipping the image on a Product. Clear the errors, then decide which warnings are worth the effort for your page type. If you run WordPress, you rarely write this by hand. Plugins such as Yoast SEO and Rank Math output LocalBusiness, Article and FAQ markup for you, and the job then is to paste your live URL here and confirm the plugin produced clean, complete markup rather than assuming it did.

Free Schema Validator

A Free Structured Data Tester Built From Real Campaigns

This free schema validator tool works as a schema markup checker for any URL, telling you what is there, what is broken and what is missing. Use it as a schema.org validator online with no account and nothing to install. It handles JSON-LD, Microdata and RDFa. Every error is named with the property it belongs to, and required fields are flagged before a rich result can show. It runs online with no account and nothing to install.

The commonest schema problem I see across 500+ projects is not invalid code. It is markup that is technically perfect and quietly lying. A Product with a price that does not match the page. Review stars marked up for reviews that do not exist. An FAQPage where the questions are not visible to a human. All of it validates cleanly and all of it puts you at risk, because Google checks markup against what the page shows. A validator cannot catch that. Only reading your own page can.

The second commonest is two plugins writing competing markup for the same page, so Google picks one and it is rarely the one you wanted. Run the validator to see everything on the page at once, then remove whichever is the duplicate. Then check how the page itself is built with the free on-page SEO analyzer, and find what it could rank for with the free keyword research tool. The rest are in the free SEO tools hub.

It helps to keep two ideas apart. JSON-LD is the format your markup is written in, Schema.org is the vocabulary of types and properties it uses, and there are two reference checkers for them, Google's Rich Results Test for whether a page qualifies for a Google feature, and the Schema.org Validator for pure vocabulary and syntax. A clean pass is necessary but never a guarantee, Google still weighs content quality and only shows a rich result when the page truly earns it. Most failures come down to a handful of things, a missing required property, a value in the wrong shape such as a price with no currency or a date that is not ISO 8601, or markup that describes something not visible on the page. The quiet danger is a template error, one broken field in a CMS can silently disable rich results across hundreds of pages at once.

About the Data

How Does the Validation Work?

The page is fetched from our own server, exactly as a search engine would, then parsed for JSON-LD script blocks, Microdata attributes and RDFa. Everything reported is read straight from your markup, so nothing is guessed. Required and recommended properties are checked against the schema.org vocabulary for each type found. One important limit. This reads the HTML your server returns, so markup injected later by JavaScript will not appear here. That is worth knowing rather than working around, because Google renders JavaScript but AI crawlers generally do not, so schema that only exists after render is invisible to a growing share of the machines reading your site.

FAQ

Schema Markup Validator FAQ

Common questions about this free tool, answered clearly.

Will schema markup get me rich results?

Schema makes you eligible for rich results, but it does not guarantee them. Google decides based on quality and the schema type. Some types, like FAQ rich results, were retired in 2026, though the markup still helps search and AI understand your page.

Which schema format should I use?

Use JSON-LD. Google recommends it and it is the easiest format to add and maintain. It sits in a single script tag instead of being mixed into your HTML.

Does schema help with AI search?

Yes. Structured data helps AI tools understand your entities, authors and facts, which improves how accurately they describe and cite you. It is one of the clearest signals you can give them.

What happened to Google's Structured Data Testing Tool?

Google retired it. It was deprecated in favour of the Rich Results Test, and after the SEO community pushed back Google moved the original tool to schema.org, where it now lives as the Schema Markup Validator at validator.schema.org. The split is deliberate. The Rich Results Test checks whether Google can show a rich result, and the Schema Markup Validator checks whether your markup is valid schema.org. If you are still searching for the old tool, those two together are what replaced it.

Is this the same as Google's Rich Results Test?

No, and they answer different questions. This tool reads your page and shows you what markup is on it and whether it is structurally sound, including types Google does not use for rich results. The Rich Results Test only checks the types Google supports and tells you whether a rich result is possible. Markup can be perfectly valid here and still produce no rich result, usually because a required property is missing or the type is not one Google displays.

Does schema markup improve rankings?

Not directly, and anyone who tells you otherwise is selling something. Google has said repeatedly that structured data is not a ranking factor. What it does is make you eligible for rich results, which change how your listing looks and can lift click-through, and it helps machines understand what your page is about. That second part matters more every year as AI search grows.

Why Work With Me

Why Hire Me for Your Structured Data

This free tool validates the markup. If you would rather have someone design the schema properly across your whole site, here are a few honest reasons businesses hire me as their SEO and digital marketing consultant in India.

Schema That Matches Your Page

Valid markup that contradicts your visible content is worse than no markup. I check what your schema claims against what the page actually shows, which is the part a validator cannot do for you.

Hands-On, Not Just Oversight

I started as a technical SEO trainee, not in a management seat, and I still write the JSON-LD myself. You get direct expertise, not a spec handed to someone else to implement.

I Built This Tool Myself

The schema validator you just used, I designed it, along with 22 other free SEO tools on this site. It is a direct look at how I audit markup before you ever become a client.

Duplicate Markup Found and Removed

Two plugins writing competing schema for the same page is the commonest mess I inherit. Google picks one and it is rarely the one you wanted. I find the duplicates and cut them.

Direct Line to Me

Messages get a reply within 24 hours on business days, and WhatsApp is the fastest way to reach me for anything urgent. You are not waiting in a support queue.

Built for Search and AI

AI crawlers do not run JavaScript, so schema injected after render is invisible to them. I make sure your markup exists in the HTML your server sends, not just in the browser.
