Missing twitter:card
Without twitter:card, Twitter falls back to Open Graph tags. Adding it gives you more control.

The og:description tag controls the description in social sharing previews.

Why this matters

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.

Source: Open Graph Protocol

URL: text/html; charset=utf-8

The og:image URL returned MIME type "text/html; charset=utf-8", which is not an image.

Expected: image/*
Why this matters

og:image pointing at HTML or a 404 means social cards render with no image — engagement plummets vs image-cards.

Learn more ▾

Social platforms validate og:image's Content-Type. If the URL returns text/html (404 page) or any non-image type, the platform skips the image and renders a text-only card. Verify your og:image URL returns image/png, image/jpeg, or image/webp with a 200 response.

Source: Open Graph Protocol

The og:url tag specifies the canonical URL for the shared content.

Why this matters

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.

Source: Open Graph Protocol

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.

Source: Open Graph Protocol

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.

Source: Open Graph Protocol

Without twitter:card, Twitter falls back to Open Graph tags. Adding it gives you more control.

Why this matters

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.

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
  • Add an apple-touch-icon and at least two PNG sizes (32x32 + 192x192)
  • twitter:card missing
  • Consider adding contactPoint — helps appear in "contact us" rich results
  • 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.

1 autoplay media element(s) -- all muted
Info::
1 autoplay media element(s) on page (muted)
Autoplay video transfers bytes whether the user engages or not -- a sustainability concern even when muted. Consider replacing with a static poster image and a click-to-play overlay; the user opts in to the bandwidth cost.

PASS
2 issues found across 26 images
Info::
24 of 26 images use legacy formats
Info::
2 image(s) rendered at a different aspect ratio than the source
The displayed dimensions distort the source -- CSS is forcing the image into a container at the wrong ratio, producing visible stretching or squashing. Either crop the source to match or use object-fit: cover (and accept the crop).
