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

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.
Without og:site_name, social cards omit the brand attribution — users see the post but not who published it.

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.
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.

BStructured Data1 JSON-LD block(s) found — some improvements recommended.REVIEW
http://schema.org/The @context should be "https://schema.org" for search engines to recognize the data.
https://schema.orgJSON-LD without @context is invalid structured data — Google ignores the entire block.

@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
