Implementing Dynamic OG Images with Notion in Next.js Blogs?

I’m building a Next.js blog using Notion. How can I dynamically assign each post’s Notion-generated image URL to its OG meta tags? See this revised code example:

import React from 'react';
import NextHead from 'next/head';

const BlogWrapper = ({ content, meta }) => {
  const blogUrl = meta.slug ? `/posts/${meta.slug}` : '/';
  const dynamicImage = meta.imageUrl || 'DEFAULT_IMAGE_URL';

  return (
    <>
      <NextHead>
        <title>{meta.title}</title>
        <meta name="description" content={meta.description} />
        <meta property="og:title" content={meta.title} />
        <meta property="og:description" content={meta.description} />
        <meta property="og:url" content={blogUrl} />
        <meta property="og:image" content={dynamicImage} />
      </NextHead>
      <div>{content}</div>
    </>
  );
};

export default BlogWrapper;

I experimented with similar functionality in a project last year, and what worked best was ensuring the Notion API returns consistent image URL data. In my case I validated that the image URL exists before adding it to the OG meta tags and implemented fallback defaults. A challenge I faced was the delayed availability of image URLs which I resolved by fetching meta data synchronously. This approach allows better SEO and link sharing previews, and it has proven to be reliable in my experience.

In my work with dynamic OG images through Notion, I encountered similar challenges regarding image availability and consistency. I found that checking the validity of the image URL during server-side rendering significantly improved reliability, especially when meta data from Notion was delayed. Integrating a clear fallback and ensuring that the image URL is well-formed helped maintain the OG preview quality. Furthermore, I modified the data fetching routine to preemptively validate images before rendering the component. This approach not only improved SEO outcomes but also provided a more consistent user experience when sharing links. My experience highlights the importance of handling asynchronous data carefully when working with external APIs like Notion.
