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

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.

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.

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.

REVIEW
1 JSON-LD block(s) found — some improvements recommended.
Warning::
Missing or invalid @context in block #1
The @context should be "https://schema.org" for search engines to recognize the data.
Got: http://schema.org/ Expected: https://schema.org
Info::

The @context should be "https://schema.org" for search engines to recognize the data.

Expected: https://schema.org
Why this matters

JSON-LD without @context is invalid structured data — Google ignores the entire block.

Learn more ▾

@context must be 'https://schema.org' (or the schema-specific URL). Without it, the block isn't parseable as schema.org JSON-LD and Google skips it. Most schema generators handle this; manual edits sometimes drop the field.

Findings

  • Missing brand name in: og:site_name, twitter:site
  • Add twitter:image — Twitter falls back to og:image only when it's larger than 300×157
  • twitter:card missing
  • Organization schema missing logo — add a logo property pointing to a square PNG
  • Organization schema missing url — point it at the canonical homepage
  • Consider adding contactPoint — helps appear in "contact us" rich results

How consistently your brand appears across channels — shared link previews, structured data, favicon, contact info.
