cslr.ch website review

19 images could be 545 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.

About 151 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.1 s faster on a phone.

Your mobile performance score is 70. Pages that score under 90 lose visitors before the first paint.

7 files block the first paint until they finish downloading. Deferring or inlining them could save about 650 ms.

About 38 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.

jimstatic.com costs a phone 118 ms of main-thread work and 345 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.

jimcdn.com costs a phone 2 ms of main-thread work and 656 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.

4 third-party services load with your homepage (jimstatic.com, jimcdn.com and jimdo-server.com and others), adding 1,002 KiB and 121 ms of main-thread time.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 150 ms).

1 long task block the main thread while loading, the longest for 60 ms. During a long task the page ignores taps.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

3 files are served with short cache lifetimes, so returning visitors download them again (2 KiB).

Your largest element takes 7.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

The page becomes fully interactive after 7.2 s. Good is under 3.8 s.

Visually, the page fills in at 5.0 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 2.4 s on a phone. Good is under 1.8 s.

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

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.

2 images (181 KiB) are JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

By the Sustainable Web Design model, a visit to your homepage emits about 0.28 g of CO₂e: 33.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

17 visible links have no text or label, so screen readers cannot say where they go.

Headings skip levels (h1 → h3), which makes the page harder to scan with a screen reader.

Your title is 67 characters, so Google will cut it off around 60: “Accueil - Club de Sports et Loisirs Remaufens - Ski-club et OJ Kids”.

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

There are 3 <h1> headlines (“Les hebdomadaires pour Toutes et Tous”, “Actualités Club” and “LE CHALET DU CHÂH À RATHVEL”). One clear main headline is easier for people and search engines.

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

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

The homepage links to 181 pages on cslr.ch and 17 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 /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.

Your homepage links to /club/galerie-archives, which answers with an error. Visitors hit a dead end and search engines drop it.

/club, /club/contacts, /club/agenda, /club/membres-et-inscription, /club/saas-fee and /club/weekend-chalet and 8 others have no meta description, so Google writes the search snippet from whatever text it finds.

/club/agenda and /club/galerie have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 84 found) and read each the way a search engine does.

20 of 22 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

The page uses 2 deprecated browser APIs that will stop working in future browsers (“Fenced Frame API is deprecated and scheduled for removal.”).

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.

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.

A local customer looking to call finds no phone number on the homepage. Add one, ideally as a tap-to-call link.

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

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

The homepage has only about 191 words of visible text; thin pages give Google and first-time buyers little to go on.

The homepage shows no opening hours. If customers visit or call, show when.

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

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.

Opening the homepage sets 4 cookies, 3 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 7 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
