Open Graph Tags Example: A Page With None
I arrived at the Sultan's court with no card, and even his marksman could not hit a man who had not been announced.
The short answer
- What it is
- Open Graph tags are meta tags that describe a page to apps that show link previews. This page type has none, or it shares its social title or description with other pages.
- Why it matters
- Without these tags, each app guesses the title and image for your link. A vague or empty preview gets fewer clicks when people share the page.
- How a crawler should report it
- A crawler should warn about missing social tags when a page has no og:* tag at all. It should warn about duplicates when pages share an og:title or og:description, ignoring case.

What a shared link looks like with no og tags
An Open Graph example shows how a page describes itself to social apps and chat tools. The tags live in the head and use the property attribute, as in <meta property="og:title" content="Page title">. The protocol names four required tags. They are og:title, og:type, og:image, and og:url. Most sites also add og:description.
Tags go missing for simple reasons. A template may have no social block, or a theme update may drop it. Some sites add the tags with JavaScript, but many link scrapers read only the raw HTML. Those scrapers never see the tags. Duplicates come from a default title or description that was set once for the whole site and never changed per page.
Browsers do not show these tags on the page. They matter when someone pastes a link. The app fetches the URL, reads the tags, and builds a preview card. With no tags, it may use the HTML title and a random image, or it may show a bare link. Open Graph is not a direct ranking signal. Its value is in how the shared link looks, and so in how many people click.
To detect the problem, fetch the raw HTML and look for any tag that starts with og:. Compare titles and descriptions across pages to find repeats. To fix it, output the four required tags from your template and fill them from each page's own data. Use the absolute URL for the image and the page. Test with the Facebook Sharing Debugger or the LinkedIn Post Inspector. Both can also clear an old cached preview.
