sunstore.ch website review

About 648 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 660 ms faster on a phone.

Your mobile performance score is 61. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Google Tag Manager, TikTok and Facebook and others), adding 1.0 MB and 890 ms of main-thread time.

Google Tag Manager costs a phone 411 ms of main-thread work and 371 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.

12 long tasks block the main thread while loading, the longest for 397 ms. During a long task the page ignores taps.

A phone's processor spends 3.1 s on main-thread work while loading, 1.9 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

24 files are served with short cache lifetimes, so returning visitors download them again (268 KiB).

The page has 1,505 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

2 images could be 44 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Polyfills for old browsers add 22 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.

Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

The page becomes fully interactive after 13.9 s. Good is under 3.8 s.

Scripts block taps and scrolling for 881 ms in total while the page loads. Good is under 200 ms.

Your largest element takes 4.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Sélection de produits pour soutenir le système immunitaire,…”.

Real visitors wait 231 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Real visitors see the first content after 2.0 s (75th percentile). Good is under 1.8 s.

Real visitors wait 1.6 s for your server to start answering (75th percentile). Good is under 800 ms.

Visually, the page fills in at 4.3 s (Speed Index). Good is under 3.4 s.

2 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' tap response (inp) went from 174 ms to 159 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 1.9 s to 1.9 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

sst-verfora-banner-standard-820x410-fr-jpg-006BL0.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 0.55 g of CO₂e: 66.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Elements must only use permitted ARIA attributes: 9 elements on the page fail this check, rated serious by axe-core.

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

ARIA input fields must have an accessible name: 1 element on the page fails this check, rated serious by axe-core.

All page content should be contained by landmarks: 13 elements on the page fail this check, rated moderate by axe-core.

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

Page should contain a level-one heading: 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.

Users should be able to zoom and scale the text up to 500%: 1 element on the page fails this check, rated minor by axe-core.

There is no <h1>, so neither visitors nor Google get a clear main headline.

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

No Open Graph image (also missing: og:title, og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

The homepage links to 516 pages on sunstore.ch and 6 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://www.sunstore.ch/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 200 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=97237921&tm=gtm002&Ver=2&mid=0288976b-37f9-4182-a746-9a3a3f4e224d&bo=2&sid=13fdb520d85811f18ed0b7ebffa173fc&vid=13fdfa60d85811f1ac73c93be10cf4a2&vids=1&msclkid=N&pi=91.

16 of 54 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

1 image is displayed at the wrong aspect ratio, so it looks stretched or squashed.

Large scripts ship without source maps.

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 phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

There is no form on the homepage, so every lead has to click through to another page first.

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 1,611 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 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 16 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
