BOpen GraphOpen Graph tags are partially configured — some improvements recommended.REVIEW
The og:url tag specifies the canonical URL for the shared content.
Without og:url, social platforms infer the canonical URL — often picking a tracking-param variant that pollutes share counts.
Learn more ▾ ▴
og:url tells the social platform which URL to count this share against. Without it, platforms use the literal URL the user pasted (which may include utm_* parameters, ref codes, etc.). Setting og:url to the canonical form keeps share-count attribution clean.

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

CStructured DataActionNo structured data (JSON-LD) found.REVIEW
Adding structured data helps search engines understand your content and can enable rich results.
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.
