Article schema is structured data that describes a page as an article, exposing fields such as the headline, author, publisher, and the published and modified dates. It helps machines understand the page as editorial content and identify who wrote it and when.
For brands, article schema is useful hygiene, especially for the date fields, since freshness is a meaningful factor in AI citations. Keeping the modified date honest and current, and backing it with genuine updates, helps signal that content is fresh. As with schema generally, treat it as support for clean parsing rather than a direct lever on AI visibility.
