Editorial page has no Article structured data
What this means
This URL is an article leaf under a blog, news or article path and carries a substantial body of text, but declares no Article, BlogPosting or NewsArticle type. Editorial markup is what makes a page eligible for the article treatment in search and Discover — headline, author, publication date — and without it the page competes as an untyped document. Listing URLs under the same path (the index itself, paginated archives, category, tag and author pages) are deliberately excluded: they are not articles, and marking them up as one would be wrong.
How to fix it
Add an Article (or BlogPosting / NewsArticle) JSON-LD block with headline, author, datePublished, dateModified, image and publisher, matching the byline and dates rendered on the page.
Fix effort
This check needs review: the change can be drafted for you, but a person has to approve the wording or choose the target before it ships.
