FIX
6 issues found across 44 images
Warning::
3 images significantly larger than display size
Resizing to display dimensions could save approximately 55 KB.
Got: ~55 KB wasted
Warning::
2 images missing explicit width/height
Images without dimensions cause layout shifts (CLS). Set explicit width and height attributes.
Info::
1 below-fold images missing loading="lazy"
Lazy loading defers below-fold images, reducing initial page weight.
Info::
30 of 44 images use legacy formats
Warning::
Total image weight: 1039 KB (1.0 MB)
Consider compressing images, using modern formats, and serving appropriately sized images.
Warning::
8 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://www.readingrockets.org/sites/default/files/styles/carousel_poster_image_desktop_small_1x/public/2023-05/rr-homepage-carousel-thinkers-1.webp?itok=lcMX2_ZU, https://www.readingrockets.org/sites/default/files/styles/carousel_poster_image_desktop_small_1x/public/2023-05/rr-homepage-carouse-readers-1.webp?itok=2GUpHDS0, https://www.readingrockets.org/sites/default/files/styles/carousel_poster_image_desktop_small_1x/public/2023-06/rr-homepage-carousel-explorers-2.webp?itok=-YH9jzpl (+5 more).

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.

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.

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.

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.

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

Info::
1 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="Reading Rockets: Launching Young Readers...", og="Reading Rockets: Launching Young Readers" Fix: either remove the redundant Twitter-specific tags (rely on inheritance) or sync them when updating OG.
