FIX

5 issues found across 31 images

1 images significantly larger than display size

Resizing to display dimensions could save approximately 0 KB.

Got: ~0 KB wasted

27 images missing explicit width/height

Images without dimensions cause layout shifts (CLS). Set explicit width and height attributes.

4 below-fold images missing loading="lazy"

Lazy loading defers below-fold images, reducing initial page weight.

All 16 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.

1 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). Sample: https://cdn.prod.website-files.com/623c9b7d180ce44819359a2d/62a1fc41979bdb4667303c51_mobile-menu.svg.

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

Open Graph

Open Graph tags are well configured for social sharing.

PASS

Open Graph tags are well configured for social sharing.

Missing og:url

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

Missing og:site_name

The og:site_name tag displays the website name in social previews.

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: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.

Missing recommended property "description" for WebSite

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

3 JSON-LD blocks found

Adding "description" 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.
