Question 1

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

Accepted Answer

No. This schema markup validator only runs local checks in your browser: valid JSON, a schema.org @context, a present @type, and a few type-specific required fields. It does not contact Google and cannot predict rich results.

Question 2

What does this schema markup validator check?

Accepted Answer

It parses the pasted JSON-LD, confirms @context contains schema.org, confirms @type is present, then applies extra rules for FAQPage (mainEntity questions and answers), Organization (name and url), Article (headline), and BreadcrumbList (itemListElement).

Question 3

Which schema types have required-field checks?

Accepted Answer

FAQPage, Organization, Article, and BreadcrumbList. Other @type values still get the JSON, @context, and @type checks. A pass here is not eligibility for Google rich results.

Question 4

Does this tool upload my JSON-LD?

Accepted Answer

No. Parsing and checks run in the browser. Nothing is sent to ToolPetal or to Google.
