karlskicks.de website review

The page has 4,614 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

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

About 364 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 450 ms faster on a phone.

5 files block the first paint until they finish downloading. Deferring or inlining them could save about 500 ms.

About 34 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 300 ms faster on a phone.

A phone's processor spends 3.1 s on main-thread work while loading, 1.1 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

14 files are served with short cache lifetimes, so returning visitors download them again (308 KiB).

8 third-party services load with your homepage (pop-convert.com, Shopify and Klaviyo and others), adding 770 KiB and 352 ms of main-thread time.

6 images could be 182 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

5 long tasks block the main thread while loading, the longest for 78 ms. During a long task the page ignores taps.

Polyfills for old browsers add 28 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.

4 KiB could be saved by minifying JavaScript.

Your largest element takes 6.7 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.

Visually, the page fills in at 6.4 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 2.6 s on a phone. Good is under 1.8 s.

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

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.

Your homepage downloads 3.4 MB in 216 requests on a phone: images 1.4 MB (39), scripts 921 KiB (60) and other files 836 KiB (103). Under 2 MB keeps phones on slow connections fast.

image0.png 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).

5 images (272 KiB) 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 0.98 g of CO₂e: 117.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

1 element hidden from screen readers can still receive keyboard focus.

Interactive controls must not be nested: 1 element on the page fails this check, rated serious by axe-core.

Scrollable region must have keyboard access: 1 element on the page fails this check, rated serious by axe-core.

21 images have no alt text, which hurts accessibility and image search.

All page content should be contained by landmarks: 10 elements on the page fail this check, rated moderate 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.

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

Elements with visible text labels do not have matching accessible names. (5 elements).

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

There are 2 <h1> headlines (“” and “Find dine nye sneakers her”). One clear main headline is easier for people and search engines.

The homepage links to 353 pages on karlskicks.de and 18 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.

https://karlskicks.eu/policies/terms-of-service, https://karlskicks.eu/pages/physical-store, https://karlskicks.eu/collections/all-sneakers and https://karlskicks.eu/collections/all-adidas have no meta description, so Google writes the search snippet from whatever text it finds.

https://karlskicks.eu/pages/physical-store has no <h1> headline, so visitors and search engines get no clear main topic.

https://karlskicks.eu/pages/physical-store, https://karlskicks.eu/collections/all-sneakers, https://karlskicks.eu/collections/all-adidas and https://karlskicks.eu/collections/adidas-special took over 3 s to send their HTML from our server.

We fetched 15 pages linked from your homepage (of 139 found) and read each the way a search engine does.

24 of 62 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

3 errors were logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 404 ()”.

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

Your homepage shows a map but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

Social proof on the homepage: 55 testimonial or review blocks. 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.

The homepage shows no opening hours. If customers visit or call, show when.

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 1,053 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Klaviyo and Meta Pixel and 1 more (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 18 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 40 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
