Brand Presence

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

D

47/100

Site name appears as

Page titleErlang/OTP twitter
og:site_nameErlang.org
twitter:site@erlang_org
Organization.name—

Inconsistent — names differ across channels

Brand assets

Favicon

8/15

single size only

Social share image

og:image set; twitter:image missing

Meta completeness

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
  • No Organization schema — Google can't render your logo in the knowledge panel
  • 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.

Why this matters

Recommended schema properties unlock richer SERP layouts — without them you get the basic rich result instead of the enhanced one.

Recommended properties expand what Google can render. E.g., adding aggregateRating to Product unlocks star ratings; adding image to Article unlocks the image-card variant. Each recommended property is a direct SERP-real-estate gain.
