· 5 checks — Internal links, mixed-content guards, Open Graph previews, and structured data rolled into one auditable list.DOpen GraphActionOpen Graph tags need attention — social sharing previews may be incomplete.FIX
The og:description tag controls the description in social sharing previews.
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.
No og:image means social shares are imageless — measurably less engaging than image-cards across every major platform.

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.

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.

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.
