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.

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: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.

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.

Adding structured data helps search engines understand your content and can enable rich results.

Adding structured data helps search engines understand your content and can enable rich results.

Why this matters

Without schema.org markup, your pages can't appear as rich results (stars, FAQs, recipes) in search.

Learn more ▾

Structured data is what unlocks rich snippets — review stars, FAQ accordions, recipe cards, breadcrumbs, etc. — that take up more SERP space and dramatically improve click-through. The schema.org vocabulary is well-documented and JSON-LD is the easiest format.
