FIX
7 issues found across 14 images
Warning::
7 images significantly larger than display size
Resizing to display dimensions could save approximately 2242 KB.
Got: ~2242 KB wasted
Warning::
9 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.
Warning::
All 9 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.
Warning::
9 images missing alt text
Alt text is essential for screen readers and SEO. Every meaningful image needs descriptive alt text.
Warning::
Total image weight: 2324 KB (2.3 MB)
Consider compressing images, using modern formats, and serving appropriately sized images.
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).

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 favicon link tags detected — browsers fall back to the generic globe
  • No Organization schema — Google can't render your logo in the knowledge panel
  • 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.

Warning::
Missing og:description
The og:description tag controls the description in social sharing previews.
Info::
og:title is short (4 characters)
Ideal length is 25–60 characters for social sharing previews.
Got: 4 chars Expected: 25–60 chars
Info::
Missing og:type
The og:type tag helps social platforms categorize the content.

The og:description tag controls the description in social sharing previews.

Why this matters

No og:description means social cards either show no subtitle or scrape the first paragraph — usually unflattering.

Learn more ▾

Without og:description, social platforms either render no subtitle or pull whatever text appears first on the page. The first paragraph is rarely written for share-card context. A purpose-written 150-200 character og:description gives a polished card.

URL: 4 chars

Ideal length is 25–60 characters for social sharing previews.

Expected: 25–60 chars
Why this matters

og:title very short — may render with awkward whitespace in social cards.

Source: Open Graph Protocol

The og:type tag helps social platforms categorize the content.

Why this matters

Default og:type is 'website' but the right value (article, product, profile) unlocks richer metadata fields and higher engagement.

Learn more ▾

og:type controls which other og: fields a platform respects. og:type=article enables og:article:published_time, author, and section — surfaced in news cards. og:type=product enables price/availability fields surfaced by Pinterest and shopping integrations. Default 'website' silently disables those.

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.

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

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.
