Question: What tool can you use to test for errors in structured data markup?
- Google's Structured Data Testing Tool
- Google's Rich Results Test
- Google's PageSpeed Insights
- Both A & B
Explanation
Google's Structured Data Testing Tool allows you to validate structured data markup on a page and identify errors or warnings. It checks the syntax and ensures compliance with Schema.org standards. Proper testing helps ensure eligibility for rich results and prevents indexing issues caused by faulty markup.
Why the other options are incorrect
Google's Rich Results Test only verifies markup that can generate rich results, not all structured data types.
Google's PageSpeed Insights measures page load performance, not structured data.
Both A & B is incorrect because only the Structured Data Testing Tool covers all structured data, not just rich results.
