mkz.si website review

17 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.4 s.

Google Tag Manager costs a phone 362 ms of main-thread work and 365 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 third-party services load with your homepage (Google Tag Manager, JSDelivr CDN and Google Analytics and others), adding 433 KiB and 381 ms of main-thread time.

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

About 217 KiB of JavaScript is downloaded but never used on this page.

4 long tasks block the main thread while loading, the longest for 151 ms. During a long task the page ignores taps.

3 files are served with short cache lifetimes, so returning visitors download them again (20 KiB).

1 image could be 15 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

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

Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

The page becomes fully interactive after 8.3 s. Good is under 3.8 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 81 ms to 104 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors wait 832 ms for your server to start answering (75th percentile). Good is under 800 ms.

Visually, the page fills in at 4.3 s (Speed Index). Good is under 3.4 s.

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

3 images further down the page (155 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 0.38 g of CO₂e: 45.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 element use ARIA attributes their role does not allow, which confuses screen readers.

2 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.

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

4 visible links have no text or label, so screen readers cannot say where they go.

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

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

Your meta description is 330 characters; Google truncates after about 160, so the end of your pitch is cut.

The homepage links to 185 pages on mkz.si and 24 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://mladinska-knjiga.si/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://mladinska-knjiga.si/trgovine, https://mladinska-knjiga.si/dogodki, https://mladinska-knjiga.si/aktualno and https://mladinska-knjiga.si/dobrezgodbe have no meta description, so Google writes the search snippet from whatever text it finds.

https://mladinska-knjiga.si/splosni-kontakti and https://mladinska-knjiga.si/dobrezgodbe have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 83 found) and read each the way a search engine does.

9 of 13 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

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 776 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, 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 14 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 7 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
