Findings

  • Brand name differs across channels — users see inconsistent identity
  • No social share image — shared links render as bare URLs
  • og:image missing
  • 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.

B
Open Graph
Open Graph tags are partially configured — some improvements recommended.
REVIEW
Open Graph tags are partially configured — some improvements recommended.
Warning::
Missing og:image
The og:image tag provides a preview image for social sharing.
Info::
og:description is long (555 characters)
Descriptions over 200 characters may be truncated in social sharing previews.
Got: 555 chars Expected: 55–200 chars

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.

Learn more ▾

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.

Source: Open Graph Protocol

URL: 555 chars

Descriptions over 200 characters may be truncated in social sharing previews.

Expected: 55–200 chars
Why this matters

og:description borderline-too-long — social platforms truncate around ~200 chars.
