FIX
6 issues found across 12 images
Warning::
1 images significantly larger than display size
Resizing to display dimensions could save approximately 21 KB.
Got: ~21 KB wasted
Warning::
12 images missing explicit width/height
Images without dimensions cause layout shifts (CLS). Set explicit width and height attributes.
Info::
8 below-fold images missing loading="lazy"
Lazy loading defers below-fold images, reducing initial page weight.
Info::
2 of 12 images use legacy formats
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://www.thousandsmiles.uk/wp-content/uploads/2023/05/invisalign-offer-banner.webp.
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://www.thousandsmiles.uk/wp-content/uploads/2023/05/invisalign-offer-banner.webp.

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

Findings

  • Missing brand name in: twitter:site, Organization.name
  • Add twitter:image — Twitter falls back to og:image only when it's larger than 300×157
  • Single favicon only — add apple-touch-icon for iOS home-screen and high-DPI support
  • No Organization schema — Google can't render your logo in the knowledge panel

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

PASS
1 OG/Twitter depth issue(s) detected
Info::
og:image aspect ratio 3.92:1 (1566×400) is outside Facebook's recommended ~1.91:1
Facebook's recommended OG image is 1200×630 (1.91:1 aspect ratio). The declared dimensions 1566×400 give a ratio of 3.92:1, 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: 3.92:1 (1566×400)

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.
