Schema Monitor
My Schema Monitor crawls your page and validates its structured data, flagging syntax errors and checking whether your configuration meets Google's rich result guidelines. Incorrect or broken schema markup can strip rich snippets from your search listings without any warning. This tool parses your JSON-LD and Microdata blocks and tells you exactly what is wrong. Run a check on any page with schema markup, or monitor regularly to catch regressions introduced by CMS updates.

--

Search engines quietly drop rich snippets when schema markup contains errors. You will not receive a notification: your listings will simply revert to standard blue links without the star ratings, pricing, or other enhancements your schema was generating. Regular monitoring is the only reliable way to catch this.
