JSON-LD Schema Change Alerts
Keep an eye on a page's schema and catch problems before they cost you rich results. You get an alert when your Product, Offer, Review, or FAQ schema disappears, turns invalid, or its price stops matching the price shoppers see, and nothing when the page is fine.

Structured Data Monitoring: Alerts When JSON-LD Schema Breaks or Schema Price Drifts From On-Page Price Structured data monitoring alerts you when JSON-LD Product, Offer, or Review schema breaks, or when the schema price drifts from the visible on-page price. Read the guideFrequently asked questions
How do I track when my structured data breaks?
Paste the URL of the page you want to watch. We check its JSON-LD on a schedule and compare it to the previous version. When Product, Offer, Review, or FAQ schema disappears, becomes invalid, or the schema price no longer matches the visible price, you get an alert. It works on any public page.
Can it catch a schema price that no longer matches the page?
Yes. This is a common cause of rich result penalties. AI compares the price inside your Offer schema against the price shown to shoppers, and alerts you when they drift apart. Reordered lines and harmless markup shuffles are ignored, so you only hear about mismatches that search engines will flag.
How quickly am I notified of a schema change?
You pick the cadence. Choose instant alerts to catch a broken deployment within minutes, or a daily or weekly digest that rolls changes into one summary. Instant suits high-traffic product pages where rich results drive clicks, while digests work for slower catalogs. It is free to start.
