In short
Article schema is structured data for an article page that describes visible facts such as its headline, author, publication date and representative image.
Mechanism and decision
Article schema describes a visibly editorial page in JSON-LD: headline, author, publication dates, representative image and its mainEntityOfPage. It should model facts readers can see, not decorate a generic landing page with an Article type.
Choose the narrowest article type, populate it from the editorial record, and compare its headline, author, dates and image with rendered HTML. A changed dateModified should represent a meaningful edit, not a routine deploy.
What you can control
A valid graph establishes machine-readable consistency. It does not guarantee a rich result, a date display or rankings.
Practical workflow
- Confirm the canonical URL and visible article type.
- Compare rendered headline, author, dates and image with JSON-LD.
- Test the public canonical URL in a structured-data diagnostic.
- Recheck after CMS or template changes.
FAQ
Article is the broad type; BlogPosting identifies a post published in a blog. Choose the type that matches the visible document.
When the article receives a meaningful content update, not merely when the site is rebuilt.
