STRUCTURED DATA CHECKER

Check Your JSON-LD Schema Before You Publish

Paste JSON-LD code or enter a page URL to inspect the structured data on the page, catch JSON syntax problems, verify @context and @type, and review every detected schema block.

Understanding Structured Data

Why Schema Audits Matter

JSON-LD tells search engines what your content means. A broken comma can stop a JSON-LD block from being decoded, while a missing @type is reported as a structural warning.

Machine-Readable Meaning

Structured data describes your page — articles, products, FAQs, events — in a format machines can parse. This audit verifies each JSON-LD block actually decodes as JSON and carries the basic Schema.org fields (@context and @type) that give it meaning.

Catch Syntax Mistakes Early

A trailing comma, a stray quote, or a missing bracket invalidates the whole block. The audit flags invalid JSON immediately, with the parser's own error message.

See What the Page Exposes

URL mode fetches the page and lists every JSON-LD script block found in the HTML — useful after plugins or themes inject markup you didn't write.

Your PageMachine-Readable Information

One Workflow, Two Validators

Structured data provides machine-readable information that search engines and other systems can use alongside the page's visible content. A clean syntax + structure audit is the first step; Google's Rich Results Test and the Schema.org Validator then perform the deeper, official validation.

What the Audit Covers

What This Schema Audit Checks

Every card below maps to a real check performed by the tool — nothing more, nothing less.

{ }

JSON Syntax

Checks whether the submitted JSON-LD can be decoded as valid JSON, and reports the parser message when it cannot.

@

Schema Context

Checks whether @context is present and refers to Schema.org.

#

Schema Type

Checks whether each schema object contains an @type property.

Schema Properties

Shows the properties and values found inside each schema object in a clean table.

Multiple Schema Blocks

Reports each detected JSON-LD block separately, with a total block count.

</>

URL or Code Inspection

Audit a live page by URL, or submit JSON-LD code directly by paste or file upload.

Structured Data in Practice

How Structured Data Can Be Used by Search Engines and AI Systems

Structured data provides machine-readable information about a page. Search engines and other systems can use that information alongside the page's visible content when interpreting what the page describes.

Search Engines
AI / LLM Systems
Why structured data matters
Helps systems understand the meaning and properties of page content.
Provides machine-readable information that can help systems interpret page content.
What your JSON-LD provides
Structured information about entities, properties, and relationships on the page.
A structured representation of information that systems may use alongside the page's actual content.
Does valid JSON-LD guarantee visibility?
No. Valid markup can make a page eligible for certain search features, but a rich result is never guaranteed.
No. Valid schema does not automatically cause an AI system to cite, mention, or recommend a page.
What matters besides markup?
Content quality, accessibility, eligibility requirements, and search engine guidelines.
The page's actual content, its clarity and accessibility, and how each system processes available information.
What should you check?
Validate the structured data and use Google's Rich Results Test when relevant.
Make sure the JSON-LD accurately represents information that also exists on the page.
What this tool does
Checks basic JSON-LD syntax and structure before deeper validation.
Helps you inspect whether the JSON-LD is structurally readable — it does not test AI visibility.

Honest by Design

This tool performs a fast first-level audit. Here is exactly what it does and does not do:

  • ✓ Reports JSON syntax and basic @context / @type structure — no hidden scoring.
  • ✓ Does not modify or "fix" your schema — it shows you what needs attention.
  • ✓ Does not guarantee rich results, rankings, or AI visibility.
  • ✓ Links to Google Rich Results Test and Schema.org Validator for deeper validation.
Quick Guide

How to Audit JSON-LD Schema

Four simple steps from raw markup to deeper validation.

1

Choose a Mode

Select Page URL to inspect a live page, or JSON-LD Code to check a snippet directly.

2

Enter Your Data

Type the URL, or paste / upload your code. The Paste buttons pull straight from your clipboard.

3

Review the Report

See detected schema blocks, their properties and values, syntax errors, and structural warnings.

4

Validate Officially

Use the built-in links to run your URL or code through Google Rich Results Test and the Schema.org Validator.

Deep Extraction

Support for Graph & Nested Structures

Modern WordPress SEO plugins frequently bundle multi-tiered schemas inside nested nodes or an @graph array. This tool recursively processes elements, separating nested components so you can inspect individual properties cleanly.

Troubleshooting Guide

Common Audit Results & What They Mean

If the audit reports a problem, the card below explains the most likely reason and how you can fix it.

×

Invalid JSON Syntax

SYNTAX ERROR

The block could not be decoded as JSON.

Solution: Look for missing commas, trailing commas, unescaped quotes, or mismatched brackets. Correct the JSON and run the audit again.

@

Missing or Non-Standard @context

WARNING

The schema has no @context, or it doesn't point to Schema.org.

Solution: Use "@context": "https://schema.org" in the schema object.

#

Missing @type

WARNING

The schema object does not declare what kind of thing it describes.

Solution: Add the appropriate @type for the content you're describing — for example Article for a blog post, Product for a product page, or FAQPage for a FAQ block.

No JSON-LD Found

NOT FOUND

No JSON-LD schema content was found in the submitted input.

Solution: Confirm the page actually outputs <script type="application/ld+json">, or create markup with a Schema Generator first.

Could Not Fetch URL

FETCH ERROR

The server could not retrieve the page — it may be down or blocking requests.

Solution: Check the URL is public and online, or switch to JSON-LD Code mode and paste the markup directly.

Decision Guide

When to Use a Schema Audit — and What to Do Next

Use the audit when you want to check JSON-LD before or after it reaches a live page. The result tells you what was found and where to go next.

When you use it
What the audit shows
What to do next
Before publishing a page
JSON syntax, @context, @type, and schema properties in your code.
Correct any errors or warnings, then run the audit again.
After adding structured data
JSON-LD blocks found in the live page HTML.
Review each detected block and confirm it contains the markup you expected.
While debugging invalid JSON
The parser error returned for the schema block.
Check commas, quotes, brackets, or other JSON formatting problems, then retest.
When @context is missing or non-standard
A structural warning for the affected schema.
Check that @context points to Schema.org.
When @type is missing
A structural warning for the schema object.
Add the appropriate schema type for the content.
When no JSON-LD is found
No JSON-LD schema content was found in the submitted input.
Confirm the page outputs JSON-LD, or switch to Code mode and inspect the markup directly.
When the URL cannot be fetched
A fetch error instead of an audit report.
Check that the URL is publicly reachable, or use JSON-LD Code mode.
After the basic audit passes
The JSON-LD decoded and passed the checks performed by this tool.
Continue with Google Rich Results Test or Schema.org Validator for deeper validation.
Frequently Asked Questions

Schema Audit FAQs

Answers based strictly on what this tool does and how it works.

?

What can this Schema Audit Tool check?

It checks JSON syntax validity, verifies @context refers to Schema.org, confirms @type exists, lists the properties and values of each schema object, and counts the JSON-LD blocks it detects.

?

Can I audit a page by URL?

Yes. The tool sends the URL to the server, fetches the page, and extracts every <script type="application/ld+json"> block from the returned HTML for analysis.

?

Can I validate JSON-LD code without a URL?

Yes. Switch to JSON-LD Code mode and paste your snippet or upload a .json / .txt / .html file. It is audited directly, no live page needed.

?

What does a syntax error mean?

It means the submitted text is not valid JSON — commonly a missing or extra comma, an incorrect quotation mark, or an unbalanced bracket. The report includes the parser's message as a clue.

?

What does a structural warning mean?

It means a basic Schema.org field is missing or non-standard: either @context doesn't point to Schema.org, or the schema object has no @type.

?

Does a successful audit mean my schema is eligible for rich results?

No. A passing audit only means the JSON decodes and the basic structure looks right. Rich-result eligibility is decided by Google's own systems, which is why the official test links are provided.

?

Why are Google Rich Results Test and Schema.org Validator links provided?

They perform deeper, official validation. This tool is a fast first check; the official tools are the right next step for full analysis.

?

Does the URL audit check the whole webpage?

No. It specifically looks for JSON-LD script blocks inside the fetched HTML and analyzes only those — not the rest of the page.

?

Is my URL or JSON-LD sent to the server?

Yes. The URL or JSON-LD code is sent to the WordPress AJAX endpoint so the audit can be processed. In URL mode, the page is fetched by the server before the JSON-LD blocks are analyzed.
