Article pages set og:type article and article meta tags

Setting og:type: 'article' without the corresponding article meta tags (article:published_time, article:author) signals an incomplete implementation. Facebook's Open Graph explorer and LinkedIn's article feed both parse these supplemental fields to categorize and timestamp content. Per ogp.me and the schema-org Article type, published_time is used by platforms to determine content freshness and sort articles in feeds; author enables attribution to contributor profiles. When the type is 'article' but the fields are absent, platforms fall back to treating the content as a generic article with unknown provenance — forfeiting the structured article display format that the type declaration was intended to unlock.

When you use og:type: 'article', include at minimum publishedTime and authors alongside it:

openGraph: {
  type: 'article',
  publishedTime: post.publishedAt.toISOString(),
  modifiedTime: post.updatedAt?.toISOString(),
  authors: [`https://yoursite.com/authors/${post.authorSlug}`],
  section: post.category,
  tags: post.tags,
}

Add this in the generateMetadata function in your blog route at app/blog/[slug]/page.tsx or equivalent. The authors field expects a URL to an author profile page, not a plain name string.
