kalkknuser.dk website review

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

Your mobile performance score is 80. Pages that score under 90 lose visitors before the first paint.

About 474 KiB of JavaScript is downloaded but never used on this page.

4 long tasks block the main thread while loading, the longest for 394 ms. During a long task the page ignores taps.

22 files are served with short cache lifetimes, so returning visitors download them again (356 KiB).

A phone's processor spends 2.4 s on main-thread work while loading, 943 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Shopify costs a phone 53 ms of main-thread work and 368 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.

8 third-party services load with your homepage (Google Tag Manager, Shopify and Trust Pilot and others), adding 920 KiB and 248 ms of main-thread time.

About 30 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.

5 images could be 91 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

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.

The page becomes fully interactive after 12.1 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 104 ms to 137 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your largest element takes 3.7 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

Scripts block taps and scrolling for 372 ms in total while the page loads. Good is under 200 ms.

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

Your homepage downloads 2.7 MB in 204 requests on a phone: scripts 1.0 MB (62), other files 896 KiB (91) and images 456 KiB (32). Under 2 MB keeps phones on slow connections fast.

1 image is downloaded at several times the size a phone draws it, for example DK_1024x1024.webp at 1,023 px wide, shown at 330 px. Resized copies would save about 3 KiB.

1 image (53 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.

1 image further down the page (81 KiB) download before anyone scrolls to it. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 0.75 g of CO₂e: 90.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

ARIA attributes must conform to valid values: 2 elements on the page fail this check, rated critical by axe-core.

53 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.

Elements must only use permitted ARIA attributes: 1 element on the page fails this check, rated serious by axe-core.

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

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.

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

1 form field has no label, so screen readers announce an empty box and autofill guesses.

Headings should not be empty: 1 element on the page fails this check, rated minor by axe-core.

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.

There are 2 <h1> headlines (“<img src="//kalkknuser.dk/cdn/shop/files/Kalkknus…” and “”). One clear main headline is easier for people and search engines.

The homepage links to 38 pages on kalkknuser.dk and 5 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://kalkknuser.dk/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://kalkknuser.dk/customer_authentication/redirect has no <title>, so Google invents the link text in results.

https://kalkknuser.dk/customer_authentication/redirect is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

https://kalkknuser.dk/customer_authentication/redirect has no meta description, so Google writes the search snippet from whatever text it finds.

https://kalkknuser.dk/customer_authentication/redirect has no <h1> headline, so visitors and search engines get no clear main topic.

https://kalkknuser.dk/customer_authentication/redirect took over 3 s to send its HTML from our server.

We fetched 15 pages linked from your homepage (of 18 found) and read each the way a search engine does.

2 errors were logged to the browser console while the page loaded, for example “Uncaught (in promise) Error: YouTube player element ID required.”.

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 analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

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 1,479 words of visible text.

The page uses urgency cues (a countdown or limited-time wording).

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Meta Pixel and TikTok Pixel (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 16 cookies, 1 of them by other companies (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 30 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
