us-sandrine.com website review

9 files are served with short cache lifetimes, so returning visitors download them again (119 KiB).

Your mobile performance score is 58. Pages that score under 90 lose visitors before the first paint.

About 84 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 900 ms faster on a phone.

4 files block the first paint until they finish downloading. Deferring or inlining them could save about 850 ms.

A phone's processor spends 3.0 s on main-thread work while loading, 1.2 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 1,761 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

8 third-party services load with your homepage (omnisnippet1.com, Clarity and loox.io and others), adding 264 KiB and 387 ms of main-thread time.

13 long tasks block the main thread while loading, the longest for 159 ms. During a long task the page ignores taps.

1 image could be 77 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 8.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Black November Sandrine”.

The first text or image appears after 3.9 s on a phone. Good is under 1.8 s.

The page becomes fully interactive after 8.2 s. Good is under 3.8 s.

Visually, the page fills in at 5.7 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 282 ms in total while the page loads. Good is under 200 ms.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 201 ms to 195 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 1.7 s to 1.9 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

By the Sustainable Web Design model, a visit to your homepage emits about 0.43 g of CO₂e: 51.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Scrollable region must have keyboard access: 2 elements on the page fail this check, rated serious by axe-core.

All page content should be contained by landmarks: 2 elements on the page fail this check, rated moderate by axe-core.

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

Headings skip levels (h1 → h3), which makes the page harder to scan with a screen reader.

Elements with visible text labels do not have matching accessible names. (1 element).

Your title is only 29 characters: “Sandrine™ - Le sérum Anti-âge”. Between 30 and 65 characters leaves room to say what you do and for whom.

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

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

Your <h1> is empty.

The homepage links to 132 pages on us-sandrine.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.

https://www.fr-sandrine.com/products/archive-pack-decouverte-cremes-12567 declares the homepage as its canonical URL, which tells Google it is a copy of the homepage and keeps it out of search results. A site-wide template setting usually causes this.

https://www.fr-sandrine.com/products/offre-3-serums-anti-age is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

/ and https://www.fr-sandrine.com/products/archive-pack-decouverte-cremes-12567 all use the title “Sandrine™ - Le sérum Anti-âge”. Search engines can't tell which page to show for a search, so each competes with the others.

https://www.fr-sandrine.com/products/offre-3-serums-anti-age, https://www.fr-sandrine.com/collections/serums, https://www.fr-sandrine.com/collections/cremes, https://www.fr-sandrine.com/collections/hydratation-repulpant, https://www.fr-sandrine.com/collections/anti-age-rides and https://www.fr-sandrine.com/collections/soin-cible-sculptant and 5 others have no meta description, so Google writes the search snippet from whatever text it finds.

https://www.fr-sandrine.com/products/archive-pack-decouverte-cremes-12567 and https://www.fr-sandrine.com/collections use the same meta description. A description written for each page earns more clicks.

https://www.fr-sandrine.com/collections has no <h1> headline, so visitors and search engines get no clear main topic.

https://www.fr-sandrine.com/products/archive-pack-decouverte-cremes-12567, https://www.fr-sandrine.com/collections/routine-soin-cible and https://www.fr-sandrine.com/collections took over 3 s to send their HTML from our server.

We fetched 15 pages linked from your homepage (of 35 found) and read each the way a search engine does.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 404 ()”.

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 guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.
