FIX
Open Graph tags need attention — social sharing previews may be incomplete.
Warning::
Missing og:title
The og:title tag controls the title shown in social sharing previews.
Warning::
Missing og:description
The og:description tag controls the description in social sharing previews.
Info::
Missing og:site_name
The og:site_name tag displays the website name in social previews.

The og:title tag controls the title shown in social sharing previews.

Why this matters

Without og:title, social shares fall back to the <title> tag — usually awkwardly truncated or branded for SEO not social.

Learn more ▾

og:title controls what appears as the headline in social-share cards (Twitter, Facebook, LinkedIn, Slack, iMessage). When omitted, platforms fall back to <title>, which is usually optimized for SEO (longer, brand-suffixed) and reads badly in social context. A 50-60-character og:title gives a clean preview.

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.

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.

Findings

  • Brand name differs across channels — users see inconsistent identity
  • Single favicon only — add apple-touch-icon for iOS home-screen and high-DPI support
  • og:title missing
  • 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.

Adding structured data helps search engines understand your content and can enable rich results.

Adding structured data helps search engines understand your content and can enable rich results.

Why this matters

Without schema.org markup, your pages can't appear as rich results (stars, FAQs, recipes) in search.

Learn more ▾

Structured data is what unlocks rich snippets — review stars, FAQ accordions, recipe cards, breadcrumbs, etc. — that take up more SERP space and dramatically improve click-through. The schema.org vocabulary is well-documented and JSON-LD is the easiest format.
