swissvax.lu website review

8 third-party services load with your homepage (swissvax.de, Google Tag Manager and Shopify and others), adding 1.6 MB and 1.1 s of main-thread time.

Your mobile performance score is 82. Pages that score under 90 lose visitors before the first paint.

About 841 KiB of JavaScript is downloaded but never used on this page.

swissvax.de costs a phone 325 ms of main-thread work and 381 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.

A phone's processor spends 3.2 s on main-thread work while loading, 1.8 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Google Tag Manager costs a phone 266 ms of main-thread work and 386 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.

17 files are served with short cache lifetimes, so returning visitors download them again (273 KiB).

11 long tasks block the main thread while loading, the longest for 257 ms. During a long task the page ignores taps.

Shopify costs a phone 202 ms of main-thread work and 551 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.

The page has 2,012 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

About 29 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.

1 file blocks the first paint until they finish downloading. Deferring or inlining it could save about 100 ms.

Polyfills for old browsers add 13 KiB JavaScript that modern phones do not need.

1 image could be 10 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

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.

3 KiB could be saved by minifying JavaScript.

The page becomes fully interactive after 20.0 s. Good is under 3.8 s.

Scripts block taps and scrolling for 438 ms in total while the page loads. Good is under 200 ms.

Visually, the page fills in at 4.8 s (Speed Index). Good is under 3.4 s.

Your largest element takes 2.7 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

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 3.8 MB in 289 requests on a phone: scripts 1.7 MB (73), other files 1.2 MB (171) and images 541 KiB (27). Under 2 MB keeps phones on slow connections fast.

SWISSVAX_Moods_Set_Collection_Kit_17.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).

By the Sustainable Web Design model, a visit to your homepage emits about 1.08 g of CO₂e: 129.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

2 dropdowns have no label.

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

1 image has no alt text, which hurts accessibility and image search.

All page content should be contained by landmarks: 26 elements on the page fail this check, rated moderate by axe-core.

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

Your title is 105 characters, so Google will cut it off around 60: “Swissvax – Entretien auto premium, polish & cire depuis 1930 – SWISSVAX Logistics UG (haf…”.

Structured data found (Organization and WebSite) but with 1 problem, for example “Organization: url points at a different host (https://swissvax.de)”.

The homepage links to 188 pages on swissvax.lu and 10 external pages.

Your Organization JSON-LD is missing 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.

https://swissvax.lu/collections/quick-detailing/oberflache_lack is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

We fetched 15 pages linked from your homepage (of 106 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=211058975&tm=gtm002&Ver=2&mid=b6d5f461-29bb-47fe-9439-4029d5c6b110&bo=2&sid=0e5085f0dcec11f1a95aabcafeecc8ea&vid=0e509860dcec11f180fb5733f1eff2e6&vids=1&msclkid=N&pi=9.

8 of 20 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: net::ERR_FAILED”.

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

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

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

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 976 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Meta Pixel and Microsoft Ads and 2 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 22 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 34 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
