REVIEW

Brand Presence

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

C

62/100

Site name appears as

Page titleThe Julia Programming Language

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
  • Single favicon only — add apple-touch-icon for iOS home-screen and high-DPI support
  • 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.
