# Schema Markup Analysis & Generation ## When to Use - Use when detecting, validating, or generating Schema.org structured data. - Use when the user asks about JSON-LD, rich results, or markup opportunities. - Use when schema validation is the main task, rather than a broader SEO audit. ## Detection 1. Scan page source for JSON-LD `<script type="application/ld+json">` 2. Check for Microdata (`itemscope`, `itemprop`) 3. Check for RDFa (`typeof`, `property`) 4. Always recommend JSON-LD as primary format (Google's stated preference) ## Validation - Check required properties per schema type - Validate against Google's supported rich result types - Test for common errors: - Missing @context - Invalid @type - Wrong data types - Placeholder text - Relative URLs (should be absolute) - Invalid date formats - Flag deprecated types (see below) ## Schema Type Status (as of Feb 2026) Read `references/schema-types.md` for the full list.
