Brand Presence

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

D

49/100

Site name appears as

Page titleMcMaster: Benefits of Studying at an Ontario University
og:site_nameMcMaster University

Inconsistent — names differ across channels

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 favicon link tags detected — browsers fall back to the generic globe
  • No Organization schema — Google can't render your logo in the knowledge panel

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

PASS
Open Graph tags are well configured for social sharing.
Critical::
og:image is not reachable
The og:image URL could not be fetched. Social platforms won't be able to display it.
Got: http://www.mcmaster.ca/wp-content/uploads/2025/10/Profile-Image_Socials_MCM_BW-Maroon_Logo_800x800.png
Info::
og:title is short (4 characters)
Ideal length is 25–60 characters for social sharing previews.
Got: 4 chars Expected: 25–60 chars
URL: http://www.mcmaster.ca/wp-content/uploads/2025/10/Profile-Image_Socials_MCM_BW-Maroon_Logo_800x800.png

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: 4 chars

Ideal length is 25–60 characters for social sharing previews.

Expected: 25–60 chars
Why this matters

og:title very short — may render with awkward whitespace in social cards.
