The og:description tag controls the description in social sharing previews.

Why this matters

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.

The og:image tag provides a preview image for social sharing.

Why this matters

No og:image means social shares are imageless — measurably less engaging than image-cards across every major platform.

Learn more ▾

Twitter, Facebook, and LinkedIn all use og:image (or twitter:image as a fallback) for share-card thumbnails. Without one, the post renders as a text-only card. A 1200x630px image (Twitter's preferred size) covers all platforms.

URL: 24 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.

Source: Open Graph Protocol

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.

Source: Open Graph Protocol

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.

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://www.schema.org Expected: https://schema.org
Info::
Custom type "NGO" — unable to validate specific properties

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.
