Always-on monitoring of your BreadcrumbList schema. Replaces the raw URL in your SERP listing with a navigable trail of categories. Sentry catches malformed position numbering, missing ListItem names, and item URL gaps. Cortex handles the fix.
Continuous audits of your BreadcrumbList schema against the 6 things that decide whether Google renders the breadcrumb trail under your URL. Each rule maps to Google's BreadcrumbList rich-result spec. Sentry catches what fails. Cortex fixes it.
A BreadcrumbList entity is present in the page's JSON-LD. Without it the SERP listing shows the raw URL instead of a navigable trail.
The `itemListElement` property is a non-empty array of ListItem entities. An empty or missing array yields no breadcrumb.
Each ListItem's `position` is an integer starting at 1 and incrementing monotonically through the array. Google requires this exact format; missing or out-of-order positions invalidate the breadcrumb.
Each ListItem includes a non-empty `name` property. Google uses these as the visible labels in the SERP breadcrumb.
Each ListItem except the last has an `item` property pointing to a valid absolute URL (or a Thing with @id or url). The final item may omit `item` since it represents the current page.
The number of ListItems equals the URL's path-segment depth + 1 (for the homepage). Significant mismatches signal a templating bug that Google may filter.
Paste any deep URL (category or product page). Sentry fetches the page, parses the JSON-LD, finds the BreadcrumbList, and validates the 6 rules. No signup, instant results, always free.
Sentry fetches your page, parses the breadcrumb schema markup, runs every rule, and renders the full result page before your next sip of coffee.
Each failed rule ships with a prescription paragraph. Hand it to engineering and the gap is closed before lunch.

6 rules in the BREADCRUMB SCHEMA Sentry. Daily 3:30 AM ET sweep.
One brain. Thirty-six pairs of eyes. Sentries monitor every visibility signal that decides whether search engines, AI engines, and ad platforms show you. Cortex reads what they see, weighs it against a unified corpus of platform documentation, and acts. Every move follows a defined decision protocol: action stated, reason given, impact named.
