FIX
7 issues found across 17 images
Warning::
5 images significantly larger than display size
Resizing to display dimensions could save approximately 279 KB.
Got: ~279 KB wasted
Warning::
13 images missing explicit width/height
Images without dimensions cause layout shifts (CLS). Set explicit width and height attributes.
Info::
6 below-fold images missing loading="lazy"
Lazy loading defers below-fold images, reducing initial page weight.
Info::
9 of 17 images use legacy formats
Warning::
4 images missing alt text
Alt text is essential for screen readers and SEO. Every meaningful image needs descriptive alt text.
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.

Info::
7 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).

Info::
No structured data (JSON-LD) found
Adding structured data helps search engines understand your content and can enable rich results.

Adding structured data helps search engines understand your content and can enable rich results.

Why this matters

Without schema.org markup, your pages can't appear as rich results (stars, FAQs, recipes) in search.

Learn more ▾

Structured data is what unlocks rich snippets — review stars, FAQ accordions, recipe cards, breadcrumbs, etc. — that take up more SERP space and dramatically improve click-through. The schema.org vocabulary is well-documented and JSON-LD is the easiest format.

Source: Google Search Central / schema.org

No structured data found

Structured data (JSON-LD) helps search engines understand your content better. Adding it can improve your search result appearance.

Common types include:

  • WebSite — your site identity and search box
  • Organization — your company information
  • Article — blog posts and news articles
  • Product — e-commerce product pages
  • BreadcrumbList — navigation paths

Rich Results Eligibility

REVIEW
No JSON-LD found -- no rich-result eligibility
Info::
No JSON-LD structured data on the page
No `<script type="application/ld+json">` blocks found. Without structured data, search engines fall back to inferring page meaning from raw HTML -- which works but doesn't unlock SERP features (rich snippets, knowledge panel, FAQ accordion, breadcrumb trail). Adding even basic JSON-LD (Organization for the site identity, BreadcrumbList for navigation context) is a low-effort SEO win.

Findings

  • Brand name differs across channels — users see inconsistent identity
  • Add an apple-touch-icon and at least two PNG sizes (32x32 + 192x192)
  • 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.
