FIX
7 issues found across 200 images
Warning::
6 images significantly larger than display size
Resizing to display dimensions could save approximately 234 KB.
Got: ~234 KB wasted
Warning::
194 images missing explicit width/height
Images without dimensions cause layout shifts (CLS). Set explicit width and height attributes.
Info::
91 below-fold images missing loading="lazy"
Lazy loading defers below-fold images, reducing initial page weight.
Info::
47 of 200 images use legacy formats
Warning::
61 images missing alt text
Alt text is essential for screen readers and SEO. Every meaningful image needs descriptive alt text.
Warning::
Total image weight: 1119 KB (1.1 MB)
Consider compressing images, using modern formats, and serving appropriately sized images.
Info::
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://www.enel.it/content/dam/asset/immagini/eneltipremia/happy-hours/banner/t-1344x672-banner-compact-magenta-happy-hour.jpg, https://www.enel.it/content/dam/asset/immagini/assistenza/luce--gas/articoli/truffe/d-706x368-enel-truffe-telefono-lente-ombra.png, https://www.enel.it/content/dam/asset/immagini/assistenza/dt-1176x1176-banner-contatti-contattaci.png (+1 more).

Brand Presence

Partial brand coverage — a few channels are missing brand signals.

Findings

  • No brand name declared in title, OG, Twitter, or structured data
  • No social share image — shared links render as bare URLs
  • Single favicon only — add apple-touch-icon for iOS home-screen and high-DPI support
  • Page title missing
  • og:image missing
  • 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.

Open Graph
Open Graph tags are partially configured — some improvements recommended.
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::
Missing og:site_name
The og:site_name tag displays the website name in social previews.

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

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.
