The term "Structured-Data-Checker" refers to a software module or tool that checks structured data - especially on websites - for accuracy, completeness, and compliance with common standards (e.g., Schema.org, JSON-LD, Microdata). This structured data is used by search engines to better understand website content and to enhance visibility in search results (e.g., through rich snippets).
Validation of structured data: Verifying whether the implemented data is correctly formatted and complete.
Error reporting and warnings: Identifying and listing errors, incomplete entries, or invalid formats.
Search result preview: Showing how structured data may appear in search engine results.
Support for multiple data formats: Analyzing and evaluating different markup formats such as JSON-LD, Microdata, or RDFa.
Automated scanning processes: Regular and automated website scans for quality assurance.
Integration with content management systems (CMS): Allowing in-context checking within CMS workflows.
Reporting and export functions: Generating validation reports for developers or SEO professionals.
