FIX
7 issues found across 200 images
Warning::
3 images significantly larger than display size
Resizing to display dimensions could save approximately 0 KB.
Got: ~0 KB wasted
Warning::
181 images missing explicit width/height
Images without dimensions cause layout shifts (CLS). Set explicit width and height attributes.
Info::
25 below-fold images missing loading="lazy"
Lazy loading defers below-fold images, reducing initial page weight.
Info::
9 of 200 images use legacy formats
Warning::
2 images missing alt text
Alt text is essential for screen readers and SEO. Every meaningful image needs descriptive alt text.
Warning::
1 above-fold image(s) marked loading="lazy" (LCP anti-pattern)
Above-fold images marked lazy delay LCP -- the browser waits for the IntersectionObserver to fire before fetching, even though the image is in the initial viewport. Remove `loading="lazy"` on above-the-fold images (especially the LCP candidate). Sample: https://conteudo.imguol.com.br/c/home/layout/vueland/icons/publicidade/selo-pagbank-horizontal-rende.png.
Info::
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://imguol.com/c/noticias/99/2026/05/21/offer-animes-desktop-1779389658409_v2_225x315.png, https://imguol.com.br/c/flash/home-uol/gif-animated/canalUOLTV-1.gif, https://conteudo.imguol.com.br/c/entretenimento/flash/85/2026/05/06/5-livros-brasileiros-contemporaneos-para-voce-colocar-na-estante-agora-1778102051873_v2_225x315.jpg (+1 more).

REVIEW
3 OG/Twitter depth issue(s) detected
Info::
og:image aspect ratio 1.00:1 (500×500) is outside Facebook's recommended ~1.91:1
Facebook's recommended OG image is 1200×630 (1.91:1 aspect ratio). The declared dimensions 500×500 give a ratio of 1.00:1, which Facebook will crop center-to-fit; the result often clips important content from the top/bottom or sides. Use a wider/taller image close to 1.91:1, or accept the cropping consequences.
Got: 1.00:1 (500×500)
Warning::
Twitter card is `summary_large_image` but OG image is 500×500 (ratio 1.00:1) -- closer to square
`twitter:card` is set to `summary_large_image` (the wide-image preview format), but the declared OG image dimensions (500×500, aspect ratio 1.00:1) are closer to square than wide. Twitter will crop the image to fit the wide format, often badly. Either: (1) provide a wider image (~2:1 ratio recommended; minimum 600×314, optimal 1200×630), or (2) change `twitter:card` to `summary` which uses a square thumbnail crop.
Got: 500×500 declared with summary_large_image card
Info::
2 Twitter Card field(s) differ from Open Graph counterparts
Twitter Cards inherit values from Open Graph tags when the Twitter-specific tag is absent (`twitter:title` falls back to `og:title`, etc.). Explicitly-set Twitter values that DIFFER from OG are usually stale -- the marketing team updates `og:title` for FB/LinkedIn previews and forgets to update `twitter:title` separately, leaving Twitter showing the old text. Mismatches: - title: twitter="UOL", og="UOL - Seu universo online" - description: twitter="Perfil oficial do UOL. Acompanhe em temp...", og="UOL, a maior empresa brasileira de conte..." Fix: either remove the redundant Twitter-specific tags (rely on inheritance) or sync them when updating OG.
Got: 2 field(s) differ

Findings

  • Brand name differs across channels — users see inconsistent identity
  • Add an apple-touch-icon and at least two PNG sizes (32x32 + 192x192)
  • Consider adding contactPoint — helps appear in "contact us" rich results
  • No discoverable contact info — trust signal is weak, legal risk is higher in regulated regions

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

og:image is not reachable
The og:image URL could not be fetched. Social platforms won't be able to display it.
Got: https://conteudo.imguol.com.br/c/home/interacao/facebook/compartilhe.png
URL: https://conteudo.imguol.com.br/c/home/interacao/facebook/compartilhe.png

The og:image URL could not be fetched. Social platforms won't be able to display it.

Why this matters

An unreachable og:image URL (404, DNS fail, slow timeout) means social platforms cache the failure and serve no image for hours.

Learn more ▾

Social platforms (Facebook, Twitter) cache OG metadata aggressively — including failed image fetches. A momentarily-broken og:image can leave your shares imageless for hours. Test og:image URLs in Facebook's Sharing Debugger to force re-cache after fixing.

Missing recommended property "sameAs" for Organization
Adding "sameAs" can improve how search engines display your content.
Info::
2 JSON-LD blocks found

Adding "sameAs" 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.

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.
