sackit.dk website review

About 1.1 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.7 s faster on a phone.

8 images could be 534 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 1.5 s faster on a phone.

Your mobile performance score is 32. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 5.1 s on main-thread work while loading, 2.7 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

37 files are served with short cache lifetimes, so returning visitors download them again (857 KiB).

8 third-party services load with your homepage (Google Tag Manager, Clarity and Facebook and others), adding 2.8 MB and 1.2 s of main-thread time.

About 70 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 450 ms faster on a phone.

Google Tag Manager costs a phone 455 ms of main-thread work and 529 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.

Polyfills for old browsers add 135 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 300 ms faster on a phone.

6 files block the first paint until they finish downloading. Deferring or inlining them could save about 400 ms.

The page has 2,351 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

rebuyengine.com costs a phone 136 ms of main-thread work and 484 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.

Shopify costs a phone 93 ms of main-thread work and 761 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.

Klaviyo costs a phone 124 ms of main-thread work and 317 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.

sleeknote.com costs a phone 51 ms of main-thread work and 295 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.

11 long tasks block the main thread while loading, the longest for 187 ms. During a long task the page ignores taps.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 100 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.

Your largest element takes 14.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

The page becomes fully interactive after 28.9 s. Good is under 3.8 s.

Visually, the page fills in at 11.7 s (Speed Index). Good is under 3.4 s.

The layout shifts by 0.658 while loading, so content jumps under the reader's thumb. Good is under 0.1.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 117 ms to 154 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Scripts block taps and scrolling for 431 ms in total while the page loads. Good is under 200 ms.

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

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 1.5 s to 1.4 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 7.2 MB in 429 requests on a phone: scripts 2.9 MB (128), images 2.4 MB (70) and other files 1.1 MB (202). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 2.04 g of CO₂e: 244.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Images must have alternative text: 2 elements on the page fail this check, rated critical by axe-core.

1 dropdown has no label.

6 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: 5 elements on the page fail this check, rated moderate by axe-core.

The viewport tag blocks pinch-zoom, which low-vision visitors rely on.

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

1 visible link has no text or label, so screen readers cannot say where it goes.

Headings should not be empty: 2 elements on the page fail this check, rated minor by axe-core.

Elements with visible text labels do not have matching accessible names. (2 elements).

Your <h1> is empty.

The homepage links to 403 pages on sackit.dk and 15 external pages.

There is no https://sackit.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.

We fetched 15 pages linked from your homepage (of 145 found) and read each the way a search engine does.

1 image failed to load on a phone, for example https://bat.bing.com/action/0?ti=343151788&tm=gtm002&Ver=2&mid=c028bed3-59b0-4364-8aaa-f08a73fafc36&bo=1&sid=6d55f8d0daa611f1b32913bda2e5b4a7&vid=6d55f060daa611f1b7cb3ff83a9c1edc&vids=1&msclkid=N&gtm_.

31 of 57 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

2 errors were logged to the browser console while the page loaded, for example “Cannot read properties of null (reading 'dataset')”.

Large scripts ship without source maps.

1 image is served at too low a resolution for sharp phone screens.

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.

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

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.

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

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 676 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Klaviyo and Meta Pixel and 3 mores (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 24 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 55 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
