Findings
- Missing brand name in: og:site_name, twitter:site, Organization.name
- Add twitter:image — Twitter falls back to og:image only when it's larger than 300×157
- No favicon link tags detected — browsers fall back to the generic globe
- twitter:card missing
- No Organization schema — Google can't render your logo in the knowledge panel
- Only partial contact info discoverable — consider adding a dedicated contact page or mailto/tel link
How consistently your brand appears across channels — shared link previews, structured data, favicon, contact info.
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.

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.

Without twitter:card, Twitter falls back to Open Graph tags. Adding it gives you more control.
Without twitter:card, Twitter renders posts as plain text — no preview image, no structured layout.
Learn more ▾ ▴
Twitter requires `<meta name="twitter:card" content="summary_large_image">` (or summary) to render share-cards at all. Without it, links appear as raw text and engagement plummets vs cards. Twitter also falls back to og:image if twitter:image isn't set, so configure both.
