scie-emb.com website review

4 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.0 s.

24 images could be 1.0 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 150 ms faster on a phone.

Your mobile performance score is 89. Pages that score under 90 lose visitors before the first paint.

About 67 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 450 ms faster on a phone.

About 47 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 300 ms faster on a phone.

The page has 1,728 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

2 third-party services load with your homepage (Shopify and shop.app), adding 64 KiB and 19 ms of main-thread time.

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.

2 files are served with short cache lifetimes, so returning visitors download them again (4 KiB).

Your largest element takes 3.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image. Most of its time is resource load delay (1.5 s).

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.

Your homepage downloads 2.9 MB in 169 requests on a phone: images 1.4 MB (46), other files 1.2 MB (87) and scripts 244 KiB (29). Under 2 MB keeps phones on slow connections fast.

Visuel_1_Oct_26.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 0.83 g of CO₂e: 100.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 element use ARIA attributes their role does not allow, which confuses screen readers.

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

2 elements hidden from screen readers can still receive keyboard focus.

2 tap targets are too small or too close together to hit reliably with a finger.

All page content should be contained by landmarks: 4 elements on the page fail this check, rated moderate by axe-core.

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

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

Alternative text of images should not be repeated as text: 1 element on the page fails this check, rated minor by axe-core.

Headings skip levels (h2 → h4 and h2 → h4), which makes the page harder to scan with a screen reader.

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

The homepage links to 358 pages on scie-emb.com and 1 external page.

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.

https://scie-emb.com/pages/contact, https://scie-emb.com/collections/promotions, https://scie-emb.com/collections/nouveautes, https://scie-emb.com/collections/gamme-ecologique, https://scie-emb.com/collections/emballer and https://scie-emb.com/collections/emballer-archive-et-classement and 9 others have no meta description, so Google writes the search snippet from whatever text it finds.

https://scie-emb.com/collections/promotions has no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 156 found) and read each the way a search engine does.

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 analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

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 842 words of visible text.

Before a visitor clicks anything, the page loads Google Analytics and Google Tag Manager (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 8 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 4 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
