DOpen GraphActionOpen Graph tags need attention — social sharing previews may be incomplete.FIX
The og:title tag controls the title shown in social sharing previews.
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.
Source: Open Graph Protocol
The og:description tag controls the description in social sharing previews.
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.
Source: Open Graph Protocol
The og:url tag specifies the canonical URL for the shared content.
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.
Source: Open Graph Protocol
The og:site_name tag displays the website name in social previews.
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.

- Add an apple-touch-icon and at least two PNG sizes (32x32 + 192x192)
- 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
