Brand Presence

Your brand name differs across channels — visitors see inconsistent identity.

Findings

  • Brand name differs across channels — users see inconsistent identity
  • No social share image — shared links render as bare URLs
  • Single favicon only — add apple-touch-icon for iOS home-screen and high-DPI support
  • og:image missing
  • 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.

Warning::
Missing og:image
The og:image tag provides a preview image for social sharing.

The og:image tag provides a preview image for social sharing.

Why this matters

No og:image means social shares are imageless — measurably less engaging than image-cards across every major platform.

Twitter, Facebook, and LinkedIn all use og:image (or twitter:image as a fallback) for share-card thumbnails. Without one, the post renders as a text-only card. A 1200x630px image (Twitter's preferred size) covers all platforms.

REVIEW
1 JSON-LD block(s) found — some improvements recommended.
Critical::
Malformed JSON-LD block #1
JSON parse error: Mismatch type map[string]interface {} with value array "at index 0: mismatched type with value\n\n\t[{\"description\":\"Auf STERN.DE fi\n\t^...............................\n"

JSON parse error: Mismatch type map[string]interface {} with value array "at index 0: mismatched type with value\n\n\t[{\"description\":\"Auf STERN.DE fi\n\t^...............................\n"

Why this matters

JSON-LD block fails to parse — Google ignores the entire block, so structured data effectively isn't there.

Common causes: trailing comma, single quotes instead of double, unescaped quote in a string value. Validate at https://validator.schema.org/ or Search Console's Rich Results Test.
