Schema Markup Issues
About Schema Markup SEO
Structured data through schema markup (JSON-LD) is the primary mechanism for earning rich results in Google Search — from FAQ accordions and how-to steps to product ratings, event listings, and breadcrumb navigation in SERPs. Pages with rich results consistently achieve higher click-through rates: a study by Milestone Research found that rich results can improve CTR by up to 30% compared to standard blue links. Beyond traditional search, schema markup is increasingly important for AI-powered platforms, as structured data helps language models understand entity relationships, factual claims, and content hierarchies. However, schema implementation is error-prone: Google's Rich Results Test frequently surfaces validation errors like missing required properties, incorrect nesting, values that don't match visible page content (which Google treats as spam), and deprecated schema types. With over 800 types in the Schema.org vocabulary, choosing the right markup and implementing it correctly requires technical precision. This reference covers every schema markup issue Digispot AI audits, from missing Organization and Breadcrumb schemas to advanced issues like conflicting schema types and incorrect speakable specifications.
