REVIEW

Brand Presence

Partial brand coverage — a few channels are missing brand signals.

0/10

no contact info discoverable

Findings

  • Missing brand name in: twitter:site
  • Add twitter:image — Twitter falls back to og:image only when it's larger than 300×157
  • Add an apple-touch-icon and at least two PNG sizes (32x32 + 192x192)
  • Consider adding contactPoint — helps appear in "contact us" rich results
  • 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.

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.

URL: 72 chars

Titles over 60 characters may be truncated in social sharing previews.

Expected: 25–60 chars
Why this matters

og:title borderline-too-long — Facebook/LinkedIn may truncate. Aim for ~60-70 characters max.
