Structured Data Detector

Scan any page for JSON-LD schema markup, meta tags, Open Graph, and Twitter Cards. See exactly what's present, what's missing, and generate a ready-to-send email for your web developer.

No AI scoring — this is deterministic detection of your page's actual markup. Structured data is how Google shows rich results and how AI engines decide what to cite.

Example output

Here's what a typical structured data audit looks like — found items, missing items, and a ready-to-send developer email.

Needs attention

5 found / 4 missing

Found

[+] JSON-LD: Organization

[+] Meta: title, description, canonical

[+] Open Graph: og:title, og:description, og:image

Missing

[-] JSON-LD: FAQPage (you have FAQ content but no schema)

[-] Twitter Card tags (twitter:card, twitter:title)

[-] JSON-LD: Product or SoftwareApplication

Recommendations

  1. Add FAQPage schema to capture FAQ rich results in Google
  2. Add Twitter Card meta tags for social sharing previews
  3. Add SoftwareApplication schema so AI engines can identify your product category

Frequently Asked Questions

What does this tool detect?
It scans your page for JSON-LD schema markup, meta tags (title, description, canonical, viewport), Open Graph tags for social sharing, and Twitter Card tags. Results are deterministic — no AI guessing.
Why does structured data matter for AI search?
AI engines like ChatGPT, Perplexity, and Google AI Overviews rely on structured data to understand and cite your content. Pages with proper schema markup are more likely to be surfaced in AI-generated answers.
What is JSON-LD?
JSON-LD (JavaScript Object Notation for Linked Data) is the recommended format for adding structured data to web pages. It sits in a <script> tag and tells search engines what your page is about — your organization, products, FAQs, articles, and more.
What should I do with the email template?
Copy the email template and send it to your web developer or agency. It contains the specific findings and recommended actions for your page, with links to Google's documentation.
How is this different from Google's Rich Results Test?
Google's tool validates existing schema for rich result eligibility. This tool gives you a broader picture — meta tags, OG tags, Twitter Cards, and JSON-LD — plus identifies what's missing and generates a developer-ready email with action items.
