Frequently Asked Questions
Everything you need to know about schema validation
What is a schema validator and why is it important?
A schema validator checks your website's structured data for errors and compliance with schema.org standards. Proper schema helps search engines understand your content and can lead to rich results (stars, prices, images) in search, improving click‑through rates.
How is your validator different from others?
We combine deep crawling, validation against schema.org, and Google's rich result requirements. Our tool not only finds errors but also provides a rich results preview and prioritizes fixes by impact.
Can I validate any website?
Yes! Our validator works with any publicly accessible website. Just enter the URL and we'll start crawling. For sites behind logins or paywalls, you may need to allow public access or use our authenticated crawl feature (available in paid plans).
What metrics are included in the report?
Each page report includes: schema type, validation status, list of errors/warnings, missing required fields, and a rich results preview. We also provide summary metrics: total schemas, invalid schemas, missing fields, and an overall health score.
Is there a free trial available?
Yes! We offer a 14-day free trial with full access to all features including unlimited schema validation, rich results preview, and exports. No credit card required.
How often should I run a schema validation audit?
For dynamic sites, we recommend running an audit monthly or after any major content or template changes. Our tool makes it easy to schedule regular crawls and compare results over time.
