The og:image URL could not be fetched. Social platforms won't be able to display it.

Why this matters

An unreachable og:image URL (404, DNS fail, slow timeout) means social platforms cache the failure and serve no image for hours.

Learn more ▾

Social platforms (Facebook, Twitter) cache OG metadata aggressively — including failed image fetches. A momentarily-broken og:image can leave your shares imageless for hours. Test og:image URLs in Facebook's Sharing Debugger to force re-cache after fixing.

URL: 16 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.

The og:type tag helps social platforms categorize the content.

Why this matters

Default og:type is 'website' but the right value (article, product, profile) unlocks richer metadata fields and higher engagement.

Learn more ▾

og:type controls which other og: fields a platform respects. og:type=article enables og:article:published_time, author, and section — surfaced in news cards. og:type=product enables price/availability fields surfaced by Pinterest and shopping integrations. Default 'website' silently disables those.

Without twitter:card, Twitter falls back to Open Graph tags. Adding it gives you more control.

Why this matters

Without twitter:card, Twitter renders posts as plain text — no preview image, no structured layout.

Learn more ▾

Twitter requires `<meta name="twitter:card" content="summary_large_image">` (or summary) to render share-cards at all. Without it, links appear as raw text and engagement plummets vs cards. Twitter also falls back to og:image if twitter:image isn't set, so configure both.

Findings

  • Missing brand name in: twitter:site
  • Add twitter:image — Twitter falls back to og:image only when it's larger than 300×157
  • No favicon link tags detected — browsers fall back to the generic globe
  • twitter:card missing
  • Consider adding contactPoint — helps appear in "contact us" rich results
  • 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.
