- Copy the full <script> tag and paste it into your page.
FAQ
Where do I paste the generated code?
Inside the <head> (or anywhere in the <body>) of the page it describes — search engines read JSON-LD wherever it appears on the page.
Does adding schema markup guarantee a rich result in Google?
No — it makes your page eligible for rich results (star ratings, FAQ dropdowns, article cards), but Google decides case by case whether to actually show them, based on many other quality factors too.
Do the FAQ questions here need to match visible text on the page?
Yes — Google's guidelines require FAQPage markup to reflect content that's actually visible to visitors on the page, not hidden questions added purely for search engines.
Can I validate the output before publishing it?
Yes — paste the generated JSON-LD into Google's Rich Results Test or the Schema Markup Validator to confirm it's well-formed before adding it to your live page.
