Image Optimization

Action

6 issues found across 110 images

FIX

6 issues found across 110 images

6 images significantly larger than display size

Resizing to display dimensions could save approximately 639 KB.

Got: ~639 KB wasted

107 below-fold images missing loading="lazy"

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

All 108 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.

Total image weight: 12620 KB (12.3 MB)

Consider compressing images, using modern formats, and serving appropriately sized images.

4 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://conengagroup.com/wp-content/uploads/2026/03/conenga_group-potenzialstudie_check_3.png, https://conengagroup.com/wp-content/uploads/2025/10/forschung_conenga_group_sketch.png, https://conengagroup.com/wp-content/uploads/2026/02/BCS_conenga_group_waben_small-1.png (+1 more).

4 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://conengagroup.com/wp-content/uploads/2026/06/Header_blog_ergebnisse_biofizz_conenga_group_s_kroehnert-800x200.png, https://conengagroup.com/wp-content/uploads/2026/06/Header_linkedIN_blog_etc-1-messkampagnen_conenga_group_j_hirsch-800x200.png, https://conengagroup.com/wp-content/uploads/2026/04/Header_linkedIN_blog_etc-1-Blogheader_datenanalyse_conenga_group_b_klug-800x200.png (+1 more).

PASS

og:description is long (275 characters)

Descriptions over 200 characters may be truncated in social sharing previews.

Got: 275 chars Expected: 55–200 chars

Missing twitter:card

Without twitter:card, Twitter falls back to Open Graph tags. Adding it gives you more control.

URL: 275 chars

Descriptions over 200 characters may be truncated in social sharing previews.

Expected: 55–200 chars

Why this matters

og:description borderline-too-long — social platforms truncate around ~200 chars.

Source: Open Graph Protocol

Without twitter:card, Twitter falls back to Open Graph tags. Adding it gives you more control.

Why this matters

Without twitter:card, Twitter renders posts as plain text — no preview image, no structured layout.

Learn more ▾

Twitter requires `<meta name="twitter:card" content="summary_large_image">` (or summary) to render share-cards at all. Without it, links appear as raw text and engagement plummets vs cards. Twitter also falls back to og:image if twitter:image isn't set, so configure both.

og:image dimensions 200×104 are below Facebook's 200×200 minimum

Facebook treats OG images smaller than 200×200 as too small to display as a preview. The actual image will likely be ignored and shares will fall back to no preview image. Use at least 200×200; optimal is 1200×630 for the standard 1.91:1 wide preview.
