REVIEW
3 issues found across 4 images
Info::
1 below-fold images missing loading="lazy"
Lazy loading defers below-fold images, reducing initial page weight.
Info::
1 image(s) wider than 400px without srcset (no responsive serving)
These images deliver the same asset to every viewport (mobile, tablet, retina). Adding srcset / <picture> lets the browser pick a viewport-appropriate variant and typically saves 40-70% of bytes on mobile. Sample: https://kling4ai.app/videos/h3-demos/hero-3.webp.
Info::
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://kling4ai.app/videos/h3-demos/hero-3.webp.

Autoplay Media

1 unmuted autoplay media element(s) -- WCAG 1.4.2 Level A failure
REVIEW
1 unmuted autoplay media element(s) -- WCAG 1.4.2 Level A failure
Warning::
1 unmuted autoplay media element(s) on page
WCAG 1.4.2 (Audio Control, Level A): if any audio plays automatically for more than 3 seconds, a mechanism must be available to pause or stop it (or to control the volume independently of the system level). Browsers also block unmuted autoplay by default in most contexts -- the media silently fails to play, frustrating users on platforms where it would have worked. Either default `muted` and provide a click-to-unmute control, or remove `autoplay` and let the user initiate playback.

Findings

  • Brand name differs across channels — users see inconsistent identity
  • Organization schema missing logo — add a logo property pointing to a square PNG
  • Organization schema missing url — point it at the canonical homepage
  • Consider adding contactPoint — helps appear in "contact us" rich results
  • Only partial contact info discoverable — consider adding a dedicated contact page or mailto/tel link

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

Why this matters

Schema markup missing required properties is silently rejected by Google — your structured data appears in source but never as a rich result.

Learn more

Each schema.org type has required properties (Article needs headline + author + datePublished; Product needs name + offers; etc.). Missing them means Google's rich-result eligibility check fails. The Search Console Rich Results Test surfaces specific gaps. Fix the missing property; rich results re-appear within hours.

Adding "url" 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.

It is built for a practical, iterative creation process: start from a single still image, test concise motion prompts, inspect the initial clip, and adjust one instruction at a time to steadily achieve your desired result."
