sanscomplexe.com website review

23 files are served with short cache lifetimes, so returning visitors download them again (594 KiB).

About 447 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.2 s faster on a phone.

A phone's processor spends 5.9 s on main-thread work while loading, 2.5 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 3,806 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Your mobile performance score is 52. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Shopify, Klaviyo and fastbundle.co and others), adding 2.6 MB and 456 ms of main-thread time.

Shopify costs a phone 250 ms of main-thread work and 1.9 MB 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.

About 82 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 310 ms faster on a phone.

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 300 ms.

6 images could be 236 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

6 long tasks block the main thread while loading, the longest for 216 ms. During a long task the page ignores taps.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

Polyfills for old browsers add 19 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.

4 KiB could be saved by minifying JavaScript.

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.

Real visitors wait 5.2 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors see the first content after 3.1 s (75th percentile). Good is under 1.8 s.

Your largest element takes 23.5 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “a woman in a pink underwear”.

The page becomes fully interactive after 26.6 s. Good is under 3.8 s.

The first text or image appears after 5.6 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 8.8 s (Speed Index). Good is under 3.4 s.

Real visitors wait 262 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Real visitors wait 993 ms for your server to start answering (75th percentile). Good is under 800 ms.

Scripts block taps and scrolling for 259 ms in total while the page loads. Good is under 200 ms.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 205 ms to 221 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 2.2 s to 2.4 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 8.2 MB in 490 requests on a phone: images 4.0 MB (69), other files 1.7 MB (282) and scripts 1.5 MB (113). Under 2 MB keeps phones on slow connections fast.

9 images (369 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 2.33 g of CO₂e: 279.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 1 element on the page fails this check, rated moderate by axe-core.

The viewport tag blocks pinch-zoom, which low-vision visitors rely on.

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

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

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

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

The homepage links to only 0 pages on your own site, so visitors and crawlers find few routes into the rest of it.

8 links have no real href, so search engines can't follow them.

1 link use generic text like “click here” or “learn more”, which tells Google nothing about the page behind it.

A phone browser shows 916 words, but the HTML your server sends has only 0. GPTBot, ClaudeBot and PerplexityBot read that HTML without running JavaScript, so they see an almost empty page. Server-side rendering or pre-rendering fixes it.

Your Organization JSON-LD is missing sameAs (social profiles), 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.

29 of 52 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

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.

We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

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 916 words of visible text.

Before a visitor clicks anything, the page loads Google Tag Manager and Klaviyo (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 17 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 37 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
