Findings
- Brand name differs across channels — users see inconsistent identity
- Add twitter:image — Twitter falls back to og:image only when it's larger than 300×157
- Single favicon only — add apple-touch-icon for iOS home-screen and high-DPI support
- twitter:card missing
- No Organization schema — Google can't render your logo in the knowledge panel
- No discoverable contact info — trust signal is weak, legal risk is higher in regulated regions
How consistently your brand appears across channels — shared link previews, structured data, favicon, contact info.
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.

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.
Source: Open Graph Protocol
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.
Source: Open Graph Protocol
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.

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.
