selency.fr website review

About 309 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.9 s faster on a phone.

Your mobile performance score is 43 (desktop: 81). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

9 files are served with short cache lifetimes, so returning visitors download them again (255 KiB).

9 images could be 293 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 600 ms faster on a phone.

8 third-party services load with your homepage (selency.com, Facebook and Cookiebot and others), adding 1.4 MB and 736 ms of main-thread time.

selency.com costs a phone 265 ms of main-thread work and 1.0 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.

10 long tasks block the main thread while loading, the longest for 264 ms. During a long task the page ignores taps.

A phone's processor spends 2.4 s on main-thread work while loading, 1.4 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

1 file blocks the first paint until they finish downloading. Deferring or inlining it could save about 100 ms.

Polyfills for old browsers add 12 KiB JavaScript that modern phones do not need.

Desktop scores 81 but mobile only 43. A gap that wide usually means heavy scripts and images that hit phones hardest.

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.

Your largest element takes 13.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Un intérieur Mid-Century Californien”.

The first text or image appears after 5.5 s on a phone. Good is under 1.8 s.

The page becomes fully interactive after 14.9 s. Good is under 3.8 s.

Scripts block taps and scrolling for 704 ms in total while the page loads. Good is under 200 ms.

Visually, the page fills in at 6.2 s (Speed Index). Good is under 3.4 s.

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

By the Sustainable Web Design model, a visit to your homepage emits about 0.52 g of CO₂e: 62.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

2 form fields have no label, so screen readers announce an empty box and autofill guesses.

1 visible link has no text or label, so screen readers cannot say where it goes.

No favicon is declared in the HTML, so browser tabs and Google's mobile results may show a generic icon.

The homepage links to 286 pages on selency.fr and 16 external pages.

https://www.selency.fr/selections/6CJSZ44B/faut-que-ca-brille and https://www.selency.fr/selections/KGY2DU3V/faut-que-ca-brille all use the title “Nickel chrome : la tendance déco qui brille | Selency”. Search engines can't tell which page to show for a search, so each competes with the others.

https://www.selency.fr/selections/6CJSZ44B/faut-que-ca-brille and https://www.selency.fr/selections/KGY2DU3V/faut-que-ca-brille use the same meta description. A description written for each page earns more clicks.

We fetched 15 pages linked from your homepage (of 198 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=199016530&tm=gtm002&Ver=2&mid=f6a891d7-0e74-4592-a89c-721e1b7b42dc&bo=1&sid=0b7abad0cd3811f1a876cf3fd4724898&vid=0b7aebc0cd3811f1a3f92943a8924f46&vids=1&msclkid=N&gtm_.

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.

Social proof on the homepage: a star rating. Pairing it with named testimonials or customer logos makes it far more convincing.

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

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 401 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, LinkedIn Insight and Meta Pixel and 2 mores (measured from a US location before any click). A consent tool (Cookiebot) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 9 cookies (measured from a US location before any click).

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