FAQ Block HTML Generator

Generate the visible FAQ HTML and the matching JSON-LD schema in one go — they stay perfectly in sync.

Visible HTML

<section class="faq">
  <details>
    <summary>Is the FAQ block accessible?</summary>
    <p>Yes — uses details/summary which screen readers handle natively.</p>
  </details>
  <details>
    <summary>Does this also emit FAQ schema?</summary>
    <p>Yes — both the HTML and the matching JSON-LD are generated together.</p>
  </details>
  <details>
    <summary>Can I add more questions?</summary>
    <p>Yes — use the + button. Each becomes both a visible row and a schema entry.</p>
  </details>
</section>

Matching JSON-LD

<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "FAQPage",
  "mainEntity": [
    {
      "@type": "Question",
      "name": "Is the FAQ block accessible?",
      "acceptedAnswer": {
        "@type": "Answer",
        "text": "Yes — uses details/summary which screen readers handle natively."
      }
    },
    {
      "@type": "Question",
      "name": "Does this also emit FAQ schema?",
      "acceptedAnswer": {
        "@type": "Answer",
        "text": "Yes — both the HTML and the matching JSON-LD are generated together."
      }
    },
    {
      "@type": "Question",
      "name": "Can I add more questions?",
      "acceptedAnswer": {
        "@type": "Answer",
        "text": "Yes — use the + button. Each becomes both a visible row and a schema entry."
      }
    }
  ]
}
</script>

Why details / summary?

<details> and <summary> are the modern, accessible default for collapsible FAQ blocks. Works without JavaScript. Falls back gracefully. Screen readers announce the disclosure correctly. No need for ARIA roles.

Visible and schema must match

Google's structured data guidelines require the marked-up Q&A to match what users actually see. Hidden / schema-only FAQs lose rich result eligibility. This tool emits both in lockstep, so they can't drift apart. If you just need the schema, use the FAQ schema generator — the visible HTML you can build by hand. The why-it-matters breakdown is in FAQ blocks vs FAQ schema.

Best practices

3–8 FAQs per page — fewer feels thin, more dilutes topical focus.
Answers under 1000 characters — Google truncates longer ones.
No links inside the answer text (Google ignores them anyway).
Open the first FAQ by default if you want users to scroll into the section.

FAQ

Should FAQ HTML and FAQ schema match exactly?

Yes - Google structured data guidelines require visible content to match marked-up content. Hidden / schema-only FAQs are non-compliant and lose rich result eligibility.

What HTML is best for FAQ blocks?

The details / summary pair is the modern, accessible default. It falls back gracefully without JavaScript, expands natively, and screen readers handle it correctly. The tool emits both the details HTML and the matching JSON-LD.

Can I add a FAQ block to multiple pages?

Yes - but each FAQ block should be genuinely relevant to that page topic. Boilerplate FAQs duplicated across many pages violate Google structured-data spam guidelines.
