ker-sun.com website review

6 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.1 s.

A phone's processor spends 4.2 s on main-thread work while loading, 1.6 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 3,480 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Your mobile performance score is 62. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Yotpo, Klaviyo and Shopify and others), adding 950 KiB and 522 ms of main-thread time.

9 files are served with short cache lifetimes, so returning visitors download them again (469 KiB).

9 images could be 443 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

About 253 KiB of JavaScript is downloaded but never used on this page.

Shopify costs a phone 107 ms of main-thread work and 349 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.

About 66 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

9 long tasks block the main thread while loading, the longest for 183 ms. During a long task the page ignores taps.

121 KiB could be saved by minifying JavaScript.

Polyfills for old browsers add 19 KiB JavaScript that modern phones do not need.

8 KiB could be saved by minifying CSS.

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.

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.

Your largest element takes 7.7 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Charger la vidéo: Chapeaux et Vêtements anti-UV Ker Sun pou…”.

The page becomes fully interactive after 17.8 s. Good is under 3.8 s.

Visually, the page fills in at 6.6 s (Speed Index). Good is under 3.4 s.

Real visitors wait 232 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 1.6 s to 2.0 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors see the first content after 2.0 s (75th percentile). Good is under 1.8 s.

Scripts block taps and scrolling for 309 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 180 ms to 169 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 4.4 MB in 261 requests on a phone: images 2.0 MB (52), scripts 1.1 MB (73) and other files 963 KiB (115). Under 2 MB keeps phones on slow connections fast.

22 images further down the page (850 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 1.24 g of CO₂e: 149.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.

Scrollable region must have keyboard access: 1 element on the page fails this check, rated serious by axe-core.

7 images have no alt text, which hurts accessibility and image search.

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

Your title is 79 characters, so Google will cut it off around 60: “Chapeaux et Vêtements anti-UV UPF 50+ pour femme, homme, enfant & bébé– Ker Sun”.

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

Your meta description is 224 characters; Google truncates after about 160, so the end of your pitch is cut.

The homepage links to 255 pages on ker-sun.com and 3 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 https://www.ker-sun.com/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 https://www.ker-sun.com/collections/vendors, which answers with an error. Visitors hit a dead end and search engines drop it.

https://www.ker-sun.com/policies/shipping-policy has no meta description, so Google writes the search snippet from whatever text it finds.

https://www.ker-sun.com/collections/nouveautes-vetements-anti-uv, https://www.ker-sun.com/policies/shipping-policy and https://www.ker-sun.com/products/jupe-anti-uv-positano-femme-canopee took over 3 s to send their HTML from our server.

We fetched 15 pages linked from your homepage (of 128 found) and read each the way a search engine does.

5 of 23 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

2 errors were logged to the browser console while the page loaded, for example “Failed to execute 'append' on 'Element': Identifier 'observer78' has already been declared”.

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

Your phone number appears as text but isn't a tel: link, so phone visitors can't tap to call.

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 321 words of visible text.

Before a visitor clicks anything, the page loads Google Analytics 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 12 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 18 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
