og:image is not reachable
The og:image URL could not be fetched. Social platforms won't be able to display it.
Got: https://cdn.prod.www.spiegel.de/public/spon/images/logos/fb_logo_default.jpg
Info::
Missing og:site_name
The og:site_name tag displays the website name in social previews.
URL: https://cdn.prod.www.spiegel.de/public/spon/images/logos/fb_logo_default.jpg

The og:image URL could not be fetched. Social platforms won't be able to display it.

Why this matters

An unreachable og:image URL (404, DNS fail, slow timeout) means social platforms cache the failure and serve no image for hours.

Learn more ▾

Social platforms (Facebook, Twitter) cache OG metadata aggressively — including failed image fetches. A momentarily-broken og:image can leave your shares imageless for hours. Test og:image URLs in Facebook's Sharing Debugger to force re-cache after fixing.

The og:site_name tag displays the website name in social previews.

Why this matters

Without og:site_name, social cards omit the brand attribution — users see the post but not who published it.

Learn more ▾

og:site_name appears in the social card chrome (above the title in Facebook/LinkedIn previews). Without it, posts read as anonymous URLs. Set it to your brand name to get free attribution on every share.

Findings

  • Brand name differs across channels — users see inconsistent identity
  • No Organization schema — Google can't render your logo in the knowledge panel
  • No discoverable contact info — trust signal is weak, legal risk is higher in regulated regions

How consistently your brand appears across channels — shared link previews, structured data, favicon, contact info.
