FIX
5 issues found across 2 images
Warning::
1 images missing explicit width/height
Images without dimensions cause layout shifts (CLS). Set explicit width and height attributes.
Warning::
All 2 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::
1 images missing alt text
Alt text is essential for screen readers and SEO. Every meaningful image needs descriptive alt text.
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://erhoeremich.de/img/logo.png.
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://erhoeremich.de/img/logo.png.

Findings

  • Missing brand name in: twitter:site, Organization.name
  • No social share image — shared links render as bare URLs
  • og:image missing
  • 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.

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 (13 characters)
Ideal length is 25–60 characters for social sharing previews.
Got: 13 chars Expected: 25–60 chars
Info::
og:description is short (52 characters)
Ideal length is 55–200 characters for social sharing previews.
Got: 52 chars Expected: 55–200 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.

Source: Open Graph Protocol

URL: 13 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: 52 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.

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.
