Quick answer
Add accurate Open Graph metadata and a suitable Twitter card to important shareable pages. Treat missing fields as a preview-quality review, not an SEO ranking guarantee and not a reason to add social tags to private or non-shareable responses.
What the issue means
Common fields include og:title, og:description, og:url, og:image, and twitter:card. Platforms may also use page HTML or cached previews when fields are absent.
Why it matters for SEO
Good metadata improves control and consistency when URLs are shared. It mainly affects social previews and click context, not organic ranking directly.
How NOTABIS detects it
The missing-social-metadata rule checks for og:title, og:description, og:image, and twitter:card in the delivered HTML. It reports missing fields but does not guarantee how a particular platform will cache or render a preview.
How to check it yourself
View the source, inspect the final URL, and validate the image dimensions and accessibility. Test a public URL with the relevant platform’s preview debugger where available.
How to fix it
Add a page-specific Open Graph title and description, a stable absolute image URL, and an appropriate Twitter card type. If you provide og:url, keep it consistent with the page’s canonical URL and use copy that matches the visible content.
For example, a public guide can declare a share title and preview image in its document head:
<meta property="og:title" content="Choosing trail shoes for wet weather">
<meta property="og:description" content="Compare grip, waterproofing, and fit before you buy.">
<meta property="og:image" content="https://example.com/images/trail-shoes.jpg">
<meta name="twitter:card" content="summary_large_image">
Use an image that is publicly retrievable and actually represents the page. Test the preview after publishing because social platforms can cache older metadata.
When this is intentional or does not need fixing
Private pages, account routes, utility endpoints, and pages not intended for sharing may not need public social metadata.
