Article Schema for Blogs: The Foundation for AI to Understand and Cite Your Content

When AI reads your blog post, it needs to answer one question first: "Is this content trustworthy?" Article schema is how you answer that question — not in words, but in structured data that AI can read immediately.

Without Article schema, AI can still read your post. But it has to guess: who wrote this? When was it written? Is it still current? When forced to guess, AI plays it safe — meaning it chooses another source it doesn't need to guess about.

Comparing Article, NewsArticle, and BlogPosting

For Vietnamese B2B/B2C business blogs: use Article for in-depth guides, BlogPosting for opinion and case study posts. No need to over-differentiate — both are handled similarly by Google and AI.

Freshness Signals — Article Schema's Secret Weapon

AI prioritizes fresh content when answering time-sensitive questions. The two fields datePublished and dateModified directly affect how likely AI is to choose your post.

Rules for dateModified:

• Update posts when there is genuinely new information — not just typo fixes
• Change dateModified each time the content is substantively updated
• Add a note at the end of the post: "Updated August 2026 — added real-world examples on Gemini 2.0"
• Do not fake dateModified to a future date — Google and AI detect it through crawl history

Rules for datePublished:

• Do not change datePublished when updating an older post — this is the date the post was first published
• Use ISO 8601 with timezone: 2026-08-08T08:00:00+07:00 instead of 2026-08-08

Implementation in Next.js App Router

In Next.js 13+ App Router, place Article schema in the generateMetadata component or use a <script> tag in the layout:

// app/blog/[slug]/page.tsx
export default function BlogPost({ post }) {
  const articleSchema = {
    "@context": "https://schema.org",
    "@type": "Article",
    headline: post.title,
    description: post.description,
    datePublished: post.date,
    dateModified: post.updatedAt || post.date,
    author: {
      "@type": "Person",
      "@id": `https://aeosaigon.com/tac-gia/${post.authorSlug}`,
      name: post.authorName,
    },
    publisher: {
      "@type": "Organization",
      "@id": "https://aeosaigon.com",
      name: "AEO Saigon",
    },
  };

  return (
    <>
      <script
        type="application/ld+json"
        dangerouslySetInnerHTML={{ __html: JSON.stringify(articleSchema) }}
      />
      {/* ... post content */}
    </>
  );
}

Pre-Publish Checklist

Before publishing any blog post, check:

• headline is no more than 110 characters and matches the <h1>
• description is 150-160 characters, not truncated
• datePublished is in correct ISO 8601 format with +07:00 timezone
• author is an object with @id pointing to a real author page
• image has url, width (1200), height (630)
• publisher uses an @id reference to the main Organization schema
• Tested through schema.org validator — no red errors
• Google's Rich Results Test shows no errors

Article schema doesn't guarantee AI will cite you today. But without it, you're racing with one hand tied behind your back — while competitors have already declared everything AI needs to know about their content.
