Warning::
1 images significantly larger than display size
Resizing to display dimensions could save approximately 266 KB.
Got: ~266 KB wasted
Warning::
1 images missing explicit width/height
Images without dimensions cause layout shifts (CLS). Set explicit width and height attributes.
Info::
1 below-fold images missing loading="lazy"
Lazy loading defers below-fold images, reducing initial page weight.
Warning::
All 1 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.

Findings

  • Brand name differs across channels — users see inconsistent identity
  • No social share image — shared links render as bare URLs
  • No favicon link tags detected — browsers fall back to the generic globe
  • og:image missing
  • No Organization schema — Google can't render your logo in the knowledge panel

How consistently your brand appears across channels — shared link previews, structured data, favicon, contact info.

REVIEW
Open Graph tags are partially configured — some improvements recommended.
Warning::
Missing og:image
The og:image tag provides a preview image for social sharing.
Info::
og:title is short (10 characters)
Ideal length is 25–60 characters for social sharing previews.
Got: 10 chars Expected: 25–60 chars

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.

Learn more

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: 10 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.

Missing recommended property "potentialAction" for WebSite
Adding "potentialAction" can improve how search engines display your content.

Adding "potentialAction" can improve how search engines display your content.

Why this matters

Recommended schema properties unlock richer SERP layouts — without them you get the basic rich result instead of the enhanced one.

Learn more

Recommended properties expand what Google can render. E.g., adding aggregateRating to Product unlocks star ratings; adding image to Article unlocks the image-card variant. Each recommended property is a direct SERP-real-estate gain.
