Findings

  • Brand name differs across channels — users see inconsistent identity
  • Add twitter:image — Twitter falls back to og:image only when it's larger than 300×157
  • No Organization schema — Google can't render your logo in the knowledge panel
  • Only partial contact info discoverable — consider adding a dedicated contact page or mailto/tel link

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