this is failing snippet test. Show more Thought process Thought process The issue is trailing commas in your JSON. JSON doesn't allow a comma after the last property in an object, but you have them in five places. Here are the lines to fix: Position 1 item — remove comma after "educationalLevel": "PreK-12", Position 2 item — remove comma after "educationalLevel": "PreK-5", Position 3 item — remove comma after "educationalLevel": "6-8", Position 4 item — remove comma after "educationalLevel": "9-12", Position 5 item — remove comma after the closing } of the "audience" object (it's the last property in that item, so no comma should follow) Each of these is the last property before a closing }, so the comma makes the JSON invalid. Google's Rich Results Test and other validators will reject the entire block because of these syntax errors. Would you like me to generate a corrected version of the full snippet? Yes.

The JSON should now validate cleanly in Google's Rich Results Test. Structured data fixed Code · HTML Claude is AI and can make mistakes. Please double-check responses.
