  "@id": "http://dbpedia.org/resource/John_Lennon",

  "born": "1940-10-09",

Adding Structured Data in Next.js

Create the following component StructuredData.jsx. Here we use the built-in component from next/head to append elements to the head of the page.

StructuredData.jsx

import Head from "next/head";
export const StructuredData = ({ data }) => {
  return (
    <Head>
      <script type="application/ld+json">{JSON.stringify(data)}</script>
    </Head>
  );
};

Use the StructuredData component in your respective component containing the UI for your post.

BlogPost.jsx

export const BlogPost = ({ post }) => {
  const structuredData = {
    "@context": "https://schema.org",
    "@type": "Article",
    headline: post.title,
    description: post.description,
    author: [
      {
        "@type": "Person",
        name: post.author,
      },
    ],
    image: post.imageUrl,
    datePublished: post.publishedAt,
  };
};
return (
  <>
    <Structured data={structuredData} />
    {/* ... the rest of your blog post */}
  </>
);

Validate Structured Data

Before deploying the changes to production, we can inspect the HTML elements on a browser to see if the changes are reflected in the <head> section of the page.

Upon successful deployment, we can use the to validate.
