OpenGraph Fallback Embed adds a custom Gutenberg block and an auto-embed fallback that renders rich link cards using OpenGraph metadata from any URL.
Features:
<ul>
<li>OpenGraph Embed block — Paste any URL to embed it as a styled card showing the page’s title, description, image, and site name.</li>
<li>Auto-embed fallback — When WordPress can’t find an oEmbed provider for a URL pasted on its own line, this plugin automatically fetches the page’s OpenGraph tags and renders a card instead of a plain link.</li>
<li>Graceful degradation — Falls back to Twitter Card meta tags, then to HTML <code><title></code> and <code><meta name="description"></code> when OpenGraph tags are missing.</li>
<li>Transient caching — Fetched metadata is cached for 7 days to minimise external requests.</li>
</ul>

Automagically adds Open Graph tags to your blog. Control how your posts and pages are presented on Facebook and other social media sites. No configuration needed.
When someone likes or shares your blog on Facebook, your header image is shown. If someone likes or shares a post, the featured image (post thumbnail) is shown. If you haven’t selected a featured image, then the plugin looks for the first image inside the post. If there aren’t any images in your post, then your blog’s header image is shown.
