Brand Presence

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

Findings

  • Missing brand name in: og:site_name, twitter:site, Organization.name
  • 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
  • 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.

REVIEW
Open Graph tags are partially configured — some improvements recommended.
Warning::
Missing og:description
The og:description tag controls the description in social sharing previews.
Info::
og:title is short (22 characters)
Ideal length is 25–60 characters for social sharing previews.
Got: 22 chars Expected: 25–60 chars
Info::
Missing og:site_name
The og:site_name tag displays the website name in social previews.

The og:description tag controls the description in social sharing previews.

Why this matters

No og:description means social cards either show no subtitle or scrape the first paragraph — usually unflattering.

Learn more

Without og:description, social platforms either render no subtitle or pull whatever text appears first on the page. The first paragraph is rarely written for share-card context. A purpose-written 150-200 character og:description gives a polished card.

URL: 22 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.

Source: Open Graph Protocol

The og:site_name tag displays the website name in social previews.

Why this matters

Without og:site_name, social cards omit the brand attribution — users see the post but not who published it.

Learn more

og:site_name appears in the social card chrome (above the title in Facebook/LinkedIn previews). Without it, posts read as anonymous URLs. Set it to your brand name to get free attribution on every share.
