seo-schema
Detect, validate, and generate Schema.org structured data. JSON-LD format preferred. Use when user says "schema", "structured data", "rich results", "JSON-LD", or "markup".
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
- Scan page source for JSON-LD
<script type="application/ld+json"> - Check for Microdata (
itemscope,itemprop) - Check for RDFa (
typeof,property) - 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)
