FIX
3 issues found across 9 images
Warning::
3 images significantly larger than display size
Resizing to display dimensions could save approximately 59 KB.
Got: ~59 KB wasted
Warning::
9 images missing explicit width/height
Images without dimensions cause layout shifts (CLS). Set explicit width and height attributes.
Info::
3 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://blockposter.net/images/generated/steps/step-upload.webp, https://blockposter.net/images/generated/steps/step-configure.webp, https://blockposter.net/images/generated/steps/step-download.webp.

Brand Presence

Your brand name differs across channels — visitors see inconsistent identity.

Findings

  • Brand name differs across channels — users see inconsistent identity
  • Single favicon only — add apple-touch-icon for iOS home-screen and high-DPI support
  • No Organization schema — Google can't render your logo in the knowledge panel
  • 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.
