Detects multiple identical schema types on the same page that may confuse search engines.
This check identifies pages with multiple instances of the same schema type (e.g., two `Product` objects, two `Organization` objects) that may not be intentional. While some duplicates are valid (e.g., multiple products on a listing page), others indicate errors.
Duplicate schema blocks can confuse search engines about which instance represents the primary entity. This can lead to incorrect rich results or no rich results at all if the search engine cannot determine which schema block is authoritative.
Unintentional duplicate schema may cause search engines to ignore your structured data entirely or display incorrect information in rich results. This is especially problematic for singleton types like Organization and WebSite.
