FIX
7 issues found across 116 images
Warning::
2 images significantly larger than display size
Resizing to display dimensions could save approximately 18 KB.
Got: ~18 KB wasted
Warning::
116 images missing explicit width/height
Images without dimensions cause layout shifts (CLS). Set explicit width and height attributes.
Info::
115 below-fold images missing loading="lazy"
Lazy loading defers below-fold images, reducing initial page weight.
Info::
1 of 116 images use legacy formats
Warning::
Total image weight: 1657 KB (1.6 MB)
Consider compressing images, using modern formats, and serving appropriately sized images.
Info::
10 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://psichologie.cz/images/home/home-hero.webp, https://psichologie.cz/media/jhoiiwy5.webp, https://psichologie.cz/media/5k0yfxqj.webp (+7 more).
Info::
2 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://psichologie.cz/images/home/home-hero.webp, https://psichologie.cz/media/n1mlyzln.webp.

Brand Presence

Findings

  • Brand name differs across channels — users see inconsistent identity
  • No social share image — shared links render as bare URLs
  • Single favicon only — add apple-touch-icon for iOS home-screen and high-DPI support
  • og:image missing
  • twitter:card missing
  • 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.

Open Graph
Open Graph tags are partially configured — some improvements recommended.
REVIEW
Open Graph tags are partially configured — some improvements recommended.
Warning::
Missing og:image
The og:image tag provides a preview image for social sharing.
Info::
Missing twitter:card
Without twitter:card, Twitter falls back to Open Graph tags. Adding it gives you more control.

The og:image tag provides a preview image for social sharing.

Why this matters

No og:image means social shares are imageless — measurably less engaging than image-cards across every major platform.

Learn more ▾

Twitter, Facebook, and LinkedIn all use og:image (or twitter:image as a fallback) for share-card thumbnails. Without one, the post renders as a text-only card. A 1200x630px image (Twitter's preferred size) covers all platforms.

Source: Open Graph Protocol

Without twitter:card, Twitter falls back to Open Graph tags. Adding it gives you more control.

Why this matters

Without twitter:card, Twitter renders posts as plain text — no preview image, no structured layout.

Learn more ▾

Twitter requires `<meta name="twitter:card" content="summary_large_image">` (or summary) to render share-cards at all. Without it, links appear as raw text and engagement plummets vs cards. Twitter also falls back to og:image if twitter:image isn't set, so configure both.

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.
