jurassic-light.com website review

About 291 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.5 s faster on a phone.

A phone's processor spends 4.5 s on main-thread work while loading, 1.7 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Your mobile performance score is 66. Pages that score under 90 lose visitors before the first paint.

6 third-party services load with your homepage (Shopify, shop.app and Judge.me and others), adding 1.2 MB and 617 ms of main-thread time.

Shopify costs a phone 590 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.

7 files block the first paint until they finish downloading. Deferring or inlining them could save about 550 ms.

About 61 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 2,819 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

5 long tasks block the main thread while loading, the longest for 122 ms. During a long task the page ignores taps.

7 files are served with short cache lifetimes, so returning visitors download them again (34 KiB).

2 images could be 23 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

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 8.6 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 12.4 s. Good is under 3.8 s.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 95 ms to 172 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 1.0 s to 1.6 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Visually, the page fills in at 5.8 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 2.7 s on a phone. Good is under 1.8 s.

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

Your homepage downloads 3.2 MB in 459 requests on a phone: other files 1.4 MB (232), scripts 969 KiB (153) and images 470 KiB (48). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.90 g of CO₂e: 107.9 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.

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.

Your title is 68 characters, so Google will cut it off around 60: “Ampoules à incandescence, halogènes et vintage – Le plus grand choix”.

Your meta description is 165 characters; Google truncates after about 160, so the end of your pitch is cut.

The homepage links to 500 pages on jurassic-light.com and 11 external pages.

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 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.
