Does valid schema guarantee rich results?

No. Valid markup is only one requirement. Search engines also evaluate page quality, policies, and query relevance.

JSON-LD is a structured data format written as JSON, usually placed in a script tag in the page head or body.

Should schema match visible content?

Yes. Markup should describe content users can actually see or verify on the page.

Start here · What is structured data?

Structured data is machine-readable markup that explains page entities, such as articles, products, FAQs, breadcrumbs, reviews, or local businesses.

Most SEO teams add it as JSON-LD, a script block that search engines can parse without changing visible page design.

Validation catches syntax errors and missing required fields before search engines ignore your markup.

When to use this tool

Before code deploy
Paste generated JSON-LD before a developer ships it to make sure the structure is valid.
Debugging rich-result issues
Use it when a page has markup but is not eligible for the rich result you expected.
Learning schema types
Inspect errors to understand which properties belong to FAQPage, Product, Article, BreadcrumbList, and other types.

Examples

Walk through these with the form above — they are practice scenarios, not live data.

FAQPage validation

Try this

Paste JSON-LD from FAQ Schema Generator.

What to look for

You should see valid syntax and a recognized FAQPage type if the question and answer pairs are complete.

Product schema check

Try this

Paste Product markup with name, image, offers, price, and availability.

What to look for

Missing fields should be called out before you add the code to the product template.

Short tutorial

Follow in order the first time you use the tool; later you can skip to the step you need.

Step 1 - Paste the full JSON-LD block
Include the <script type="application/ld+json"> wrapper only if the tool accepts it; otherwise paste just the JSON.
Step 2 - Fix syntax first
Broken commas, quotes, and braces must be fixed before semantic validation can be trusted.
Step 3 - Review warnings
Warnings may not block parsing, but they often explain why a rich result is incomplete.
