Top Stories, Discover & Article Rich Result

Get Your Articles into Top Stories, Discover & AI Summaries

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.

Article Discoverability Optimization

Continuous Article Schema Monitoring

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.

RULE · 1

article_entity_present

Article entity detected

An Article (or BlogPosting / NewsArticle / ScholarlyArticle) entity is present. Without it the page is ineligible for Top Stories, Discover, and the Article rich result.

RULE · 2

headline_present

headline is non-empty

The `headline` property is present and non-empty. Google uses this as the article title in SERP listings.

RULE · 3

image_present

image URL or ImageObject present

The `image` property points to at least one valid image URL (or ImageObject with valid url / contentUrl). Required for Top Stories thumbnail.

RULE · 4

datePublished_iso8601

datePublished is ISO 8601

The `datePublished` property is a valid ISO 8601 date string. Google requires this format; non-standard dates are silently ignored.

RULE · 5

author_present

author is Person or Organization with name

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.

RULE · 6

publisher_with_logo

publisher is Organization with logo

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.

RULE · 7

headline_length_compliant

headline ≤110 chars

The `headline` is 110 characters or fewer. Google's guideline; longer headlines are truncated in SERP listings.

RULE · 8

dateModified_valid

dateModified ≥ datePublished

If `dateModified` is set, it is on or after `datePublished`. Detects backdating bugs that confuse Google's freshness ranking.

RULE · 9

mainEntityOfPage_canonical

mainEntityOfPage matches page URL

The `mainEntityOfPage` property's URL or @id matches the page's canonical URL. Strong canonicalization signal.

RULE · 10

description_present

description is substantive

The `description` property includes substantive text (≥30 chars). Used by AI engines and Discover to compose article previews.

RULE · 11

multiple_images_present

Multiple images (≥2 URLs)

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.
