orcz.cz website review

About 144 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.4 s faster on a phone.

Your mobile performance score is 49 (desktop: 77). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

5 third-party services load with your homepage (Google Tag Manager, Clarity and cookiehub.eu and others), adding 542 KiB and 565 ms of main-thread time.

Google Tag Manager costs a phone 413 ms of main-thread work and 341 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

5 long tasks block the main thread while loading, the longest for 306 ms. During a long task the page ignores taps.

6 files block the first paint until they finish downloading. Deferring or inlining them could save about 300 ms.

A phone's processor spends 2.2 s on main-thread work while loading, 765 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 250 ms).

5 files are served with short cache lifetimes, so returning visitors download them again (31 KiB).

Desktop scores 77 but mobile only 49. A gap that wide usually means heavy scripts and images that hit phones hardest.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

Your largest element takes 7.8 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “IT řešení pro B2B a veřejný sektor”. Most of its time is element render delay (4.1 s).

The first text or image appears after 4.6 s on a phone. Good is under 1.8 s.

The page becomes fully interactive after 8.1 s. Good is under 3.8 s.

Visually, the page fills in at 5.3 s (Speed Index). Good is under 3.4 s.

The layout shifts by 0.205 while loading, so content jumps under the reader's thumb. Good is under 0.1.

Scripts block taps and scrolling for 220 ms in total while the page loads. Good is under 200 ms.

Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

By the Sustainable Web Design model, a visit to your homepage emits about 0.20 g of CO₂e: 23.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

28 tap targets are too small or too close together to hit reliably with a finger.

ARIA dialog and alertdialog nodes should have an accessible name: 1 element on the page fails this check, rated serious by axe-core.

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

1 visible link has no text or label, so screen readers cannot say where it goes.

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

Your meta description is 194 characters; Google truncates after about 160, so the end of your pitch is cut.

No Open Graph image (also missing: og:title, og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

The homepage links to 81 pages on orcz.cz and 7 external pages.

There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

There is no https://www.orcz.cz/llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.

/, https://www.orcz.cz/en, https://www.orcz.cz/de and https://www.orcz.cz/sk all use the title “OR-CZ | IT řešení pro B2B a veřejný sektor”. Search engines can't tell which page to show for a search, so each competes with the others.

https://www.orcz.cz/o-nas, https://www.orcz.cz/kariera, https://www.orcz.cz/skoleni, https://www.orcz.cz/novinky, https://www.orcz.cz/zdravotnictvi and https://www.orcz.cz/marie-pacs and 2 others have no meta description, so Google writes the search snippet from whatever text it finds.

https://www.orcz.cz/en, https://www.orcz.cz/de and https://www.orcz.cz/sk use the same meta description. A description written for each page earns more clicks.

We fetched 15 pages linked from your homepage (of 34 found) and read each the way a search engine does.

3 images failed to load on a phone, for example https://www.orcz.cz/sites/default/files/styles/rozcestnik/public/images/2024/01/rozcestnik_or_system_bg.png.webp?itok=Cm9ZEgKK.

10 of 14 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

2 errors were logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

The homepage carries about 537 words of visible text.

Before a visitor clicks anything, the page loads Google Analytics, Google Tag Manager and Microsoft Clarity (measured from a US location before any click). No consent tool was detected. Visitors from the EU, UK and several US states must be asked first.

Opening the homepage sets 2 cookies (measured from a US location before any click).

No known cookie consent tool loads with the page. Some sites build their own banner, and some only show one to visitors from the EU.

Loading the homepage contacts 10 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
