Structured Data Extractor (JSON-LD, Microdata & RDFa)

Extract structured data from any web page for SEO audits.

This Actor:

• Extracts JSON-LD blocks (<script type="application/ld+json">)
• Detects & extracts Microdata (itemscope, itemtype, itemprop)
• Detects & extracts basic RDFa (property, typeof, about, resource, vocab)
• Highlights detected schema.org types and reports common issues (missing @type, non-schema.org @context, parse errors)

Input

• Start URLs: pages to analyze.
• Follow internal links (optional): crawl additional pages for site-wide audits.
• Extraction toggles for JSON-LD / Microdata / RDFa.

Output

• Dataset: one item per analyzed page (counts, detected types, warnings/errors).
• Key-Value Store:
  • SUMMARY: run summary + top schema.org types
  • REPORT: compact per-page report

Example API call

{
"startUrls":[{"url":"https://example.com"},{"url":"https://json-ld.org/"}],
"maxPages":10,
"followLinks":false,
"validateSchemaOrg":true
}

Quick start

Store page: https://apify.com/scrappy_garden/structured-data-extractor

Paste this into Input and click Run:

{
"startUrls":[
{
"url":"https://example.com/"
}
],

}
}

Outputs (what you get)

• Dataset: Dataset items typically include fields like: url, statusCode, title, jsonLdCount, microdataItemCount, rdfaStatementCount, schemaTypes, warnings, errors, extractedAt.
• Key-value store: REPORT, SUMMARY

Tips (trust + predictable results)

• Start with 1–3 URLs to validate behavior, then scale up.
• If a target blocks requests, enable Proxy and/or slow down concurrency in Input.
• Use the SUMMARY / REPORT keys (when present) for automation pipelines and monitoring.
