Question 1

What does a JSON-LD validator check?

Accepted Answer

It confirms your structured data is valid JSON, has the required @context and @type, and includes the fields that Google and AI search engines expect for the schema type you're using (for example a Product needs a name and offers; an FAQPage needs mainEntity questions with answers).

Question 2

Why does structured data matter for AI search?

Accepted Answer

JSON-LD is the machine-readable layer AI engines and Google use to classify and quote your pages. Valid, complete schema raises your odds of being surfaced in AI answers and rich results; broken or incomplete schema is silently ignored.

Question 3

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

Accepted Answer

This is a fast client-side sanity check for syntax and common required fields. For rich-result eligibility specifically, also run Google's Rich Results Test and Schema.org's validator. Use this to catch the obvious mistakes instantly before you ship.
