og:image is not reachable

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

Got: https://www.gsk.com/media/p3clrlre/stvg_2_2022_smtlab_17_hess.jpg?width=600&format=webp&quality=100&v=1dbd496701ca530

og:title is short (10 characters)

Ideal length is 25–60 characters for social sharing previews.

Got: 10 chars Expected: 25–60 chars

Missing og:type

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

Missing og:site_name

The og:site_name tag displays the website name in social previews.

URL: https://www.gsk.com/media/p3clrlre/stvg_2_2022_smtlab_17_hess.jpg?width=600&format=webp&quality=100&v=1dbd496701ca530

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: 10 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.

Brand name differs across channels — users see inconsistent identity
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
Only partial contact info discoverable — consider adding a dedicated contact page or mailto/tel link
