FIX
4 issues found across 27 images
Warning::
27 images missing explicit width/height
Images without dimensions cause layout shifts (CLS). Set explicit width and height attributes.
Info::
24 below-fold images missing loading="lazy"
Lazy loading defers below-fold images, reducing initial page weight.
Warning::
All 18 images use legacy formats (JPEG/PNG/GIF)
WebP offers 25-35% smaller files than JPEG. Use <picture> with <source type="image/webp"> for modern format support.
Warning::
2 images missing alt text
Alt text is essential for screen readers and SEO. Every meaningful image needs descriptive alt text.

Findings

  • Missing brand name in: og:site_name, twitter:site, Organization.name
  • No social share image — shared links render as bare URLs
  • Add an apple-touch-icon and at least two PNG sizes (32x32 + 192x192)
  • og:image 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.

Warning::
Missing og:image
The og:image tag provides a preview image for social sharing.
Info::
og:title is short (5 characters)
Ideal length is 25–60 characters for social sharing previews.
Got: 5 chars Expected: 25–60 chars
Info::
og:description is short (1 characters)
Ideal length is 55–200 characters for social sharing previews.
Got: 1 chars Expected: 55–200 chars
Info::
Missing og:site_name
The og:site_name tag displays the website name in social previews.

The og:image tag provides a preview image for social sharing.

Why this matters

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.

URL: 5 chars

Ideal length is 25–60 characters for social sharing previews.

Expected: 25–60 chars
Why this matters

og:title very short — may render with awkward whitespace in social cards.

Source: Open Graph Protocol

URL: 1 chars

Ideal length is 55–200 characters for social sharing previews.

Expected: 55–200 chars
Why this matters

og:description very short — provides little context in social cards.

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.
