Findings

  • Brand name differs across channels — users see inconsistent identity
  • og:title missing
  • 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.

REVIEW
Open Graph tags are partially configured — some improvements recommended.
Warning::
Missing og:title
The og:title tag controls the title shown in social sharing previews.
Info::
Missing og:url
The og:url tag specifies the canonical URL for the shared content.
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:url tag specifies the canonical URL for the shared content.

Why this matters

Without og:url, social platforms infer the canonical URL — often picking a tracking-param variant that pollutes share counts.

Learn more ▾

og:url tells the social platform which URL to count this share against. Without it, platforms use the literal URL the user pasted (which may include utm_* parameters, ref codes, etc.). Setting og:url to the canonical form keeps share-count attribution clean.

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.

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.

  • Product — e-commerce product pages
  • BreadcrumbList — navigation paths
