How to use Google Structured Data Testing Tool to validate Schema?

When you need to verify whether a web page's Schema markup complies with Google's specifications, you can use the Google Structured Data Testing Tool (now integrated into the Rich Results Test tool) for verification. This tool can detect the grammatical correctness, completeness of structured data, and whether it meets the requirements for search result display. The steps to use are as follows: 1. Access the tool: Open the Google Rich Results Test page through a browser (the original Structured Data Testing Tool has been integrated here). 2. Enter content: Select "URL" or "Code" mode, and enter the web page address or directly paste the Schema code (such as JSON-LD, Microdata, etc.). 3. Run the test: Click the "Test URL" or "Test Code" button, and the tool will automatically analyze and generate a result report. 4. Check and fix: Check for errors (such as missing required fields, formatting errors) and warnings (such as suggested supplementary information) in the report, adjust the Schema markup according to the prompts, and retest. It is recommended to verify immediately after deploying the Schema, and regularly review it through this tool. At the same time, monitor the actual effect with the "Enhanced Results" report in Google Search Console to ensure that the structured data continues to meet search requirements and improve the visibility of the web page in search results.
