Frequently Asked Questions

How do I ensure the results are accurate?
Always verify the validation results against your live page after deploying changes to guarantee accuracy.

Is my markup processed locally in my browser?
When you paste markup directly, it runs client-side. When validating by URL, our server fetches the JSON-LD blocks.

Can I validate multiple snippets at once?
Currently, the tool supports one markup snippet at a time; however, you can run validations consecutively for different snippets.

What should I do if I encounter persistent errors?
If errors persist, review the structured data documentation for your specific schema type and ensure your markup adheres to the latest guidelines.
