Analysis of 1,800 websites in French-speaking Switzerland: the state of digital revealed

Switzerland is often associated with excellence. The precision of our watches, the punctuality of our trains, the reliability of our infrastructure. The “Swiss Made” label is a worldwide promise of impeccable quality.

Yet there is one area where this reputation collapses abruptly as soon as you scratch the surface: our digital presence.

At Smart Impact, we do not rely on impressions, but on data. So we carried out one of the broadest analyses ever conducted on the digital ecosystem of French-speaking Switzerland. We audited 1,820 company websites in French-speaking Switzerland using Google’s tools (PageSpeed Insights Mobile).

The finding is a cold shower. If our websites were watches, 9 out of 10 would lose several minutes every hour.

Here is why the web in French-speaking Switzerland is in a state of emergency. Discover the results from the sites analysed.

The Google PageSpeed Insights audit: methodology and scope

Before diving into the results, it is crucial to understand how we went about it. To get a faithful picture of reality, we used the Google PageSpeed Insights API in December 2025.

Why this tool? Because it is the benchmark Google itself uses to rank your sites in its search results. It is not a subjective opinion on design, but a precise technical measurement of real user experience.

Our sample covers 1,820 unique sites of companies based in French-speaking Switzerland, from the small local SME to large institutions. The tests were run simulating a 4G mobile connection, as that is now the standard usage for more than 70% of your visitors (source: Linkedin).

The key findings: excellence is an anomaly

The results of our audit break the myth of a Switzerland at the cutting edge of digital technology. The spread of performance scores is unambiguous:

The elite is tiny (7.4%): only a fraction of sites reach a score of excellence (above 90/100). They are the only ones offering an instant, smooth experience in line with modern standards.
The soft middle is enormous (76.3%): the vast majority sit in the “needs improvement” band (a score between 50 and 89). These sites work, but they are heavy, sluggish and invisible to demanding algorithms.
The red zone (16.4%): more than one site in six is technically poor (a score below 50). In 2025, offering that kind of experience on mobile is commercial suicide.

The conclusion is brutal: for 92.6% of companies in French-speaking Switzerland, the website is a brake on growth rather than an accelerator.

Why your website is slowing your growth (literally)

How is it that a country this wealthy and this educated produces such an average web? Our analysis of the technical data reveals a prime culprit: digital obesity. We have confused “premium” with “heavy”.

1. The excessive weight of French-speaking Swiss websites

In Switzerland, we like things to be beautiful. We invest fortunes in branding, 4K photo shoots and drone videos. That is commendable for brand image, but catastrophic for technical performance if it is not optimised.

Our data shows that the average French-speaking Swiss site weighs around 4 MB. That is enormous for an unstable mobile connection on the train between Lausanne and Geneva. With an average of 2.1 MB of images per page, we are asking our customers' smartphones to download the equivalent of a small app just to display a home page.

2. Loading (LCP) in the red

LCP (Largest Contentful Paint) measures how long the main element of the page takes to appear. It is the Achilles heel of the French-speaking Swiss web. Because of these uncompressed media files, most sites go well beyond the recommended threshold of 2.5 seconds.

Your site may be a Ferrari to look at, but you have put a Twingo engine in it and filled the boot with breeze blocks.

3. The Scripts vs Performance war

The other major lesson from our audit of the 1800 sites analysed is the brutal correlation between JavaScript and performance. We observed a gap of 19 performance points between sites that are “light” on scripts and those that are “heavy”.

It is often the symptom of an accumulation of marketing tools: chat, tracking pixels, social widgets, pop-ups… Each addition blocks the processor of the user’s phone. The result: the user clicks, but nothing happens. They get annoyed and leave.

4. The direct impact on conversion

This is not just a technical question. That neglect has a direct financial cost:

Google demotes you: since mobile-first indexing, Google penalises slowness. If you are among the 92.6% of slow sites, you are handing your SEO positions to your competitors.
Your customers leave: 40% of users abandon a site if it takes more than 3 seconds to load. On mobile, the cart abandonment rate is close to 80% in 2025. Technical slowness has become the leading cause of lost online revenue (source: wpbeginner+1).

The experts’ view: why is this a strategic problem?

To go beyond the figures, you need to understand the strategic implications. In a saturated market, user experience becomes the main differentiator.

“For Generation Z and millennials, speed means reliability. A slow site in 2025 signals an ageing, out-of-date company, whatever the intrinsic quality of your products or services.”

This finding highlights a gap between how a company is perceived (often excellent) and how it shows up digitally (mediocre). For a decision-maker, ignoring these metrics is like ignoring a water leak in your shop: customers come in, slip, and leave straight away.

Recommendations: how to join the elite 7% of the sites analysed?

That observation may sound alarming, but it carries excellent news. Since most of the market is mediocre, joining the top 7% is a massive competitive opportunity.

And contrary to popular belief, this does not necessarily mean throwing out your current website to rebuild it for CHF 50’000. The problem is often not the design or the content, but the mechanics “under the bonnet”.

Here are three concrete actions for optimising your existing site:

Intelligent media compression: use modern formats such as WebP or AVIF. They cut image weight dramatically with no perceptible visual loss.
Cleaning up the scripts: audit your third-party tools. Do you really need to load that chat script on every page? Defer the loading of anything non-essential.
Advanced caching: use CDN (content delivery network) solutions to serve your content as close to the user as possible.

The urgency of digital transformation

Switzerland has managed to build the longest tunnels and the most complex watches in the world. It is time to apply that same engineering rigour to our digital assets.

At Smart Impact, we do not believe in systematic redesigns, but in surgical optimisation. You do not need to rebuild everything, you need to tune the machine better.
