kooperativa.sk website review

21 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.1 s.

About 371 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 860 ms faster on a phone.

Your mobile performance score is 62 (desktop: 90). Pages that score under 90 lose visitors before the first paint.

5 third-party services load with your homepage (Google Tag Manager, koop.sk and vshosting.cz and others), adding 3.7 MB and 287 ms of main-thread time.

vshosting.cz costs a phone 0 ms of main-thread work and 2.8 MB 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.

Google Tag Manager costs a phone 207 ms of main-thread work and 325 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.

The page has 1,868 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

koop.sk costs a phone 80 ms of main-thread work and 602 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.

38 KiB could be saved by minifying JavaScript.

About 36 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 170 ms faster on a phone.

6 long tasks block the main thread while loading, the longest for 183 ms. During a long task the page ignores taps.

Desktop scores 90 but mobile only 62. 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 6.4 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

The page becomes fully interactive after 9.7 s. Good is under 3.8 s.

Your homepage downloads 3.8 MB in 114 requests on a phone: media 2.7 MB (4), scripts 796 KiB (51) and images 184 KiB (19). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.09 g of CO₂e: 130.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Certain ARIA roles must contain particular children: 1 element on the page fails this check, rated critical by axe-core.

Certain ARIA roles must be contained by particular parents: 1 element on the page fails this check, rated critical by axe-core.

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 1 element on the page fails this check, rated moderate by axe-core.

ARIA role should be appropriate for the element: 17 elements on the page fail this check, rated minor by axe-core.

Headings skip levels (h2 → h4), which makes the page harder to scan with a screen reader.

No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.

No twitter:card tag. X falls back to Open Graph, which is set, so this is minor.

The homepage links to 134 pages on kooperativa.sk and 21 external pages.

There is no https://kooperativa.sk/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://kooperativa.sk/ekooperativa-fo has no meta description, so Google writes the search snippet from whatever text it finds.

https://kooperativa.sk/poistenie/auto/automat took over 3 s to send its HTML from our server.

We fetched 15 pages linked from your homepage (of 69 found) and read each the way a search engine does.

10 of 32 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

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

Large scripts ship without source maps.

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.

Social proof on the homepage: 1 trust badge. Pairing it with named testimonials or customer logos makes it far more convincing.

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 1,246 words of visible text.

Before a visitor clicks anything, the page loads Google Analytics and Google Tag Manager (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 1 cookie (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 5 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
