Question 1

What is JSON-LD?

Accepted Answer

JSON-LD (JSON for Linking Data) is a format for embedding structured data in a webpage as a script tag, letting a page describe itself — its content, organization, products, and more — in a machine-readable way alongside its regular HTML.

Question 2

What is Schema.org?

Accepted Answer

Schema.org is a shared vocabulary of types (like Article, Product, or Event) and properties, maintained collaboratively by Google, Microsoft, Yahoo and Yandex, that search engines and other services use to interpret structured data consistently.

Question 3

What is structured data used for?

Accepted Answer

It helps search engines and other automated systems understand a page's content more precisely than they could from the visible text and HTML alone. Some structured data types are also documented as eligible for specific Google Search rich-result treatments, though eligibility for those changes over time and isn't guaranteed by adding the markup alone.

Question 4

Does adding structured data guarantee a rich result in Google Search?

Accepted Answer

No. Valid, well-formed structured data is a prerequisite for many rich results, but Google independently decides whether and how to display any enhanced result, and that decision depends on Google's own current policies, content quality, and other factors this tool has no control over.

Question 5

Does structured data directly improve rankings?

Accepted Answer

Not documented as a direct ranking factor. Structured data primarily affects how a result can be displayed (for types Google supports as rich results), not where a page ranks.

Question 6

Is FAQPage schema still worth adding?

Accepted Answer

It remains valid Schema.org structured data and can still be useful to services other than Google Search. However, Google discontinued the FAQ rich result feature in Google Search entirely in May 2026, so adding FAQPage markup no longer produces a distinct FAQ rich result there.

Question 7

Does WebSite schema still add a sitelinks search box?

Accepted Answer

No. Google discontinued the sitelinks search box feature in November 2024. This generator's WebSite output intentionally omits the potentialAction/SearchAction markup that used to target that feature, since including it would revive an outdated claim.

Question 8

What's the difference between JSON-LD and microdata?

Accepted Answer

Both express the same underlying Schema.org vocabulary. JSON-LD is a single self-contained script block placed anywhere in the page, independent of the visible markup; microdata is embedded directly inline as attributes on the HTML elements it describes. Google supports both, and this tool generates JSON-LD specifically, the format Google's own documentation recommends.

Question 9

Can I validate structured data that's already live on a page?

Accepted Answer

This tool validates JSON-LD you generate here or paste into its Custom JSON-LD mode. It doesn't fetch or crawl a live URL — for that, this tool's JSON syntax and structural checks are a starting point, and Google's own Rich Results Test is the authoritative check for actual rich-result eligibility.

Question 10

What does this tool's validation actually check?

Accepted Answer

It checks that your JSON is syntactically valid and that the object has the basic structure Schema.org itself expects for the selected type, such as a @context, a @type, and that type's typical minimum fields. It does not check, and never claims to check, Google-specific rich-result eligibility requirements.

Question 11

Should I add fake ratings or reviews to get a rich result?

Accepted Answer

No. This tool never generates a rating, review count, or review from nothing — Product and SoftwareApplication rating fields are left out unless you explicitly enter real values, and fabricating them would misrepresent your content to both users and Google, which can lead to manual action.

Question 12

Is my data sent anywhere when I use this tool?

Accepted Answer

No. Everything you type is generated and validated entirely in your browser. Q3 Labs doesn't receive, log, or store the schema content you enter — including in Custom JSON-LD mode, where pasted JSON is only ever parsed locally, never executed or sent anywhere.

Question 13

How do I add the generated JSON-LD to my website?

Accepted Answer

Copy the full script tag output and paste it anywhere in your page's HTML, most commonly inside the , though Google also accepts it in the . If you're on a CMS, look for a custom code or header-scripts field rather than editing template files directly.

Question 14

Can I use more than one schema type on the same page?

Accepted Answer

Yes. Multiple JSON-LD script tags can coexist on one page — for example, an Organization block alongside a BreadcrumbList and an Article — as long as each one accurately describes the content actually on that page.
