Frequently Asked Questions
What errors can the tester identify?
Common errors include syntax mistakes, missing required properties, incorrect data types, and values outside allowed ranges.
Will invalid structured data hurt my SEO?
Invalid markup won't directly hurt rankings, but it prevents rich snippets. You won't get the click-through benefits of proper structured data.
What's the difference between warnings and errors?
Errors prevent rich snippets. Warnings indicate issues that should be fixed but may not block rich snippets if some properties are present.
Do I need to test every page?
Test one example of each content type. If your site generates markup consistently, testing representative pages is usually sufficient.
Can I test markup behind authentication?
The tester uses code you paste, so it doesn't matter if your site is behind authentication. Test using the page source HTML.
How often should I retest my markup?
Retest after making changes to your structured data. Annually test to ensure your markup still meets current schema.org standards.
