refresher.sk website review

A phone's processor spends 4.3 s on main-thread work while loading, 576 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

About 379 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 730 ms faster on a phone.

Your mobile performance score is 67 (desktop: 90). Pages that score under 90 lose visitors before the first paint.

8 files block the first paint until they finish downloading. Deferring or inlining them could save about 450 ms.

8 third-party services load with your homepage (Google/Doubleclick Ads, Google FundingChoices and Criteo and others), adding 508 KiB and 353 ms of main-thread time.

4 long tasks block the main thread while loading, the longest for 198 ms. During a long task the page ignores taps.

About 23 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

2 images could be 56 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

8 files are served with short cache lifetimes, so returning visitors download them again (52 KiB).

Polyfills for old browsers add 23 KiB JavaScript that modern phones do not need.

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 5.4 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “zrádci”.

The page becomes fully interactive after 9.3 s. Good is under 3.8 s.

The first text or image appears after 2.3 s on a phone. Good is under 1.8 s.

The layout shifts by 0.147 while loading, so content jumps under the reader's thumb. Good is under 0.1.

Scripts block taps and scrolling for 248 ms in total while the page loads. Good is under 200 ms.

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

Your homepage downloads 2.6 MB in 84 requests on a phone: other files 1.2 MB (22), scripts 704 KiB (27) and images 344 KiB (17). Under 2 MB keeps phones on slow connections fast.

bbc6gpbfa1wsxy6s.jpg is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

1 image (32 KiB) is 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 0.74 g of CO₂e: 89.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

Scrollable region must have keyboard access: 4 elements on the page fail this check, rated serious by axe-core.

All page content should be contained by landmarks: 65 elements on the page fail this check, rated moderate by axe-core.

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

8 form fields have no label, so screen readers announce an empty box and autofill guesses.

Elements with visible text labels do not have matching accessible names. (12 elements).

Structured data found (Organization and WebSite) but with 2 problems, for example “Organization: missing name”.

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

The homepage links to 61 pages on refresher.sk and 39 external pages.

Your Organization JSON-LD is missing name, logo, description and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

There is no https://refresher.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.

We fetched 15 pages linked from your homepage (of 20 found) and read each the way a search engine does.

21 of 69 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

1 third-party cookie is set on load; browsers are restricting these, so whatever relies on them breaks.

1 error was logged to the browser console while the page loaded, for example “%c%d font-size:0;color:transparent NaN”.

Chrome logged issues while loading the page (“Cookie”).

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: 3 trust badges. Pairing it with named testimonials or customer logos makes it far more convincing.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach 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 340 words of visible text.

Before a visitor clicks anything, the page loads Criteo and Google Ads (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 5 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 17 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
