FAQ
 
Frequently asked questions
 
 
 
What is JSON-LD structured data?
 
JSON-LD is the format Google recommends for schema markup — a small script in your page’s HTML that describes the content (an FAQ, a product, an article) so search engines can show rich results.
 
 
Does this tool validate the markup?
 
Yes. It checks three things live: structural errors and missing Google-required fields (errors), missing recommended fields that affect rich-result eligibility (warnings), and format problems like non-absolute URLs or non-ISO dates.
 
 
Which schema types are supported?
 
Eight of the most common: FAQPage, Article, Product, LocalBusiness, Organization, Person, BreadcrumbList and WebSite. We add more based on what people ask for.
 
 
Is it free and private?
 
Yes — no signup, no limits, and everything runs in your browser. We dogfood it too: every page on this site uses JSON-LD generated from the same config.
