umk.pl website review

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

27 images could be 4.2 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

6 files are served with short cache lifetimes, so returning visitors download them again (3.1 MB).

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

4 KiB could be saved by minifying CSS.

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.

Real visitors wait 906 ms for your server to start answering (75th percentile). Good is under 800 ms.

Visually, the page fills in at 5.6 s (Speed Index). Good is under 3.4 s.

17 images have no width and height attributes, so the layout jumps as each one loads.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 79 ms to 87 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 1.3 s to 1.3 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 10.7 MB in 72 requests on a phone: images 5.6 MB (45), fonts 5.0 MB (7) and stylesheets 31 KiB (14). Under 2 MB keeps phones on slow connections fast.

11 images are downloaded at several times the size a phone draws them, for example rektor-umk-swieto-uczelni.jpg at 540 px wide, shown at 41 px. Resized copies would save about 600 KiB.

18 images (1.7 MB) are JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

By the Sustainable Web Design model, a visit to your homepage emits about 3.02 g of CO₂e: 362.4 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.

Interactive controls must not be nested: 7 elements on the page fail this check, rated serious by axe-core.

4 elements hidden from screen readers can still receive keyboard focus.

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 2 elements on the page fail this check, rated moderate by axe-core.

ARIA role should be appropriate for the element: 4 elements on the page fail this check, rated minor by axe-core.

Elements with visible text labels do not have matching accessible names. (3 elements).

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

Your meta description is only 49 characters: “Strona Uniwersytetu Mikołaja Kopernika w Toruniu.”. 70 to 160 characters is enough to sell the click.

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 167 pages on umk.pl and 69 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.umk.pl/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.umk.pl/rekrutacja has no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 67 found) and read each the way a search engine does.

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: 8 customer or partner logos. Pairing it with named testimonials or customer logos makes it far more convincing.

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

There is no form on the homepage, so every lead has to click through to another page first.

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 622 words of visible text.

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.
