Schema.org & Rich Snippet Developer Reference

JSON-LD vs Microdata vs RDFa

JSON-LD: Recommended by Google; clean JavaScript object format inside <script type="application/ld+json">.
Microdata / RDFa: Inline HTML attributes (itemscope, itemprop, typeof).

@graph & Entity Relationships

The tester resolves @graph arrays and @id entity references, mapping parent-child relationships (Product → Offer, FAQPage → Question → Answer).

SSRF & XSS Safeguards

Live URL audits validate IP addresses against internal blocks. Extracted page content and raw JSON-LD markup are HTML-escaped to prevent script execution.

Search Engine Eligibility

Valid Schema.org markup is required for rich search features, but search engine algorithms determine final SERP display based on site quality and query relevance.
