4 issues found across 63 images
FIX
4 issues found across 63 images
Warning::
4 images missing explicit width/height
Images without dimensions cause layout shifts (CLS). Set explicit width and height attributes.
Info::
7 below-fold images missing loading="lazy"
Lazy loading defers below-fold images, reducing initial page weight.
Warning::
All 48 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.
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://wikimediafoundation.org/wp-content/uploads/2026/10/960px-Close-up_of_Lady_Justice_statue_holding_scales_symbolizing_justice_and_fairness.jpg?resize=300,200, https://wikimediafoundation.org/wp-content/uploads/2026/10/SwarmRobot_org.jpg?resize=300,200, https://wikimediafoundation.org/wp-content/uploads/2026/09/Wikimedia_UNGA_IMG_3281.jpg?resize=300,200.

1 HTTP resource(s) loaded on HTTPS page
REVIEW
1 HTTP resource(s) loaded on HTTPS page
Critical::
HTTP link loaded on HTTPS page
Modern browsers block or warn about HTTP resources on HTTPS pages. Change the URL to use HTTPS.
Got: http://gmpg.org/xfn/11 Expected: https://gmpg.org/xfn/11
URL: http://gmpg.org/xfn/11

Modern browsers block or warn about HTTP resources on HTTPS pages. Change the URL to use HTTPS.

Expected: https://gmpg.org/xfn/11
Why this matters

Mixed content — HTTP resource on HTTPS page. Browser may block silently or warn user.

Source: Google Chrome Security

B
Autoplay Media
1 autoplay media element(s) -- all muted
REVIEW
1 autoplay media element(s) -- all muted
Info::
1 autoplay media element(s) on page (muted)
Autoplay video transfers bytes whether the user engages or not -- a sustainability concern even when muted. Consider replacing with a static poster image and a click-to-play overlay; the user opts in to the bandwidth cost.

Brand Presence

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

Findings

  • Brand name differs across channels — users see inconsistent identity
  • Add twitter:image — Twitter falls back to og:image only when it's larger than 300×157
  • 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.

Rich Results Eligibility
1 JSON-LD block(s) declaring 5 schema type(s)
PASS
1 JSON-LD block(s) declaring 5 schema type(s)
Info::
SiteLinks Search Box markup detected
The page declares a `WebSite` schema with a `potentialAction` of `SearchAction`. This makes the homepage eligible for Google's in-SERP search box -- a high-visibility SERP feature for branded queries.
Info::
5 rich-result schema type(s) declared
Inventory of structured-data types on the page (each may unlock a different SERP feature): BreadcrumbList, ImageObject, Organization, WebPage, WebSite Search engines decide whether to render rich results based on content quality + page-level signals; declaring the schema is necessary but not sufficient.
