Always-on monitoring of your Article schema. The signal Google uses for Top Stories, Discover, and the Article rich result; the signal AI engines use to identify byline-attributed content for citation. Sentry catches missing publisher logos, malformed dates, and oversized headlines. Cortex handles the fix.
Continuous audits of your Article schema against the 11 things that decide Top Stories eligibility, Discover inclusion, and the Article rich result. Each rule maps to Google's Article structured-data spec. Sentry catches what fails. Cortex fixes it.
An Article (or BlogPosting / NewsArticle / ScholarlyArticle) entity is present. Without it the page is ineligible for Top Stories, Discover, and the Article rich result.
The `headline` property is present and non-empty. Google uses this as the article title in SERP listings.
The `image` property points to at least one valid image URL (or ImageObject with valid url / contentUrl). Required for Top Stories thumbnail.
The `datePublished` property is a valid ISO 8601 date string. Google requires this format; non-standard dates are silently ignored.
The `author` property references a Person or Organization with a valid non-empty `name`. E-E-A-T signal used for AI byline-attribution citations.
The `publisher` property is an Organization with both `name` AND `logo` (URL or ImageObject). The logo must be ≥60px tall per Google's Article spec.
The `headline` is 110 characters or fewer. Google's guideline; longer headlines are truncated in SERP listings.
If `dateModified` is set, it is on or after `datePublished`. Detects backdating bugs that confuse Google's freshness ranking.
The `mainEntityOfPage` property's URL or @id matches the page's canonical URL. Strong canonicalization signal.
The `description` property includes substantive text (≥30 chars). Used by AI engines and Discover to compose article previews.
The `image` property includes 2+ images. Google recommends providing 16:9, 4:3, and 1:1 ratio variants so Top Stories and Discover can pick the best fit per surface.

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.
