swissvax.ch website review

About 1.1 MB of JavaScript is downloaded but never used on this page.

8 third-party services load with your homepage (Google Tag Manager, Facebook and Shopify and others), adding 1.7 MB and 906 ms of main-thread time.

Your mobile performance score is 68. Pages that score under 90 lose visitors before the first paint.

Google Tag Manager costs a phone 360 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.

A phone's processor spends 3.7 s on main-thread work while loading, 1.7 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

16 files are served with short cache lifetimes, so returning visitors download them again (286 KiB).

Shopify costs a phone 197 ms of main-thread work and 837 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 2,126 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

12 long tasks block the main thread while loading, the longest for 217 ms. During a long task the page ignores taps.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 200 ms).

1 file blocks the first paint until they finish downloading. Deferring or inlining it could save about 150 ms.

About 27 KiB of CSS is downloaded but never applied on this page.

Polyfills for old browsers add 13 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.

3 KiB could be saved by minifying JavaScript.

The page becomes fully interactive after 22.4 s. Good is under 3.8 s.

Your largest element takes 4.1 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 121 ms to 154 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Scripts block taps and scrolling for 582 ms in total while the page loads. Good is under 200 ms.

Visually, the page fills in at 4.7 s (Speed Index). Good is under 3.4 s.

Your homepage downloads 4.3 MB in 331 requests on a phone: scripts 2.0 MB (76), other files 1.3 MB (213) and images 504 KiB (24). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.22 g of CO₂e: 146.0 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.

6 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: 8 elements on the page fail this check, rated moderate by axe-core.

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

1 link inside paragraphs relies on colour alone to stand out.

Your title is 84 characters, so Google will cut it off around 60: “Swissvax – Premium car care, polishes & car waxes hand-made since 1930 – SWISSVAX AG”.

Your meta description is 170 characters; Google truncates after about 160, so the end of your pitch is cut.

1 link has no real href, so search engines can't follow it.

The homepage links to 161 pages on swissvax.ch and 37 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.

We fetched 15 pages linked from your homepage (of 97 found) and read each the way a search engine does.

The page uses 1 deprecated browser API that will stop working in future browsers (“The Protected Audience API is deprecated and will be removed in a future release.”).

3 errors were logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

Large scripts ship without source maps.

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 1,378 words of visible text.

Before a visitor clicks anything, the page loads Google Analytics, Google Tag Manager and Microsoft 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 4 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 13 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
