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.

• ID: social-meta-per-content-type

• Severity: low

• What to look for: For blog posts or article pages, check whether the OG metadata includes article-specific properties: article:published_time, article:modified_time, article:author, and article:section. These are used by Facebook and LinkedIn to categorize and display content correctly in their article feeds. In Next.js App Router, these are set via openGraph.type: 'article' alongside openGraph.publishedTime, openGraph.modifiedTime, openGraph.authors, and openGraph.section. Count all instances found and enumerate each.

• Pass criteria: Blog post or article pages that set og:type: "article" also include at least article:published_time and article:author in their OG metadata. At least 1 implementation must be confirmed.

• Fail criteria: Pages that use og:type: "article" do not include the corresponding article meta tags (article:published_time, article:author).

• Skip (N/A) when: The project has no blog, news, or article content. Also skip if og:type: "article" is not used anywhere in the project.

• Detail on fail: "app/blog/[slug]/page.tsx sets og:type='article' but does not include article:published_time or article:author — article-specific social features unavailable"

• Remediation: When you use og:type: "article", include the complementary article properties for richer platform integration:

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

  Facebook uses these for article categorization in the Open Graph explorer. LinkedIn uses published_time for its "shared article" display format.
