Structured Data Best Practices

  • Use JSON-LD format: Google recommends JSON-LD over Microdata or RDFa for structured data
  • Test with Google's Rich Results Test: Always validate your structured data at search.google.com/test/rich-results
  • Keep data accurate: Structured data must reflect actual visible content on the page
  • Use specific types: The more specific your @type (e.g., SoftwareApplication vs. Product), the better
  • Monitor in Search Console: Check the Enhancements report for structured data errors after deployment
  • AI assistants use structured data: LLMs like ChatGPT and Claude parse JSON-LD to understand and cite your content
