nexsmart.fr website review

The page has 38,834 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

A phone's processor spends 15.7 s on main-thread work while loading, 5.2 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

zuzana.ai costs a phone 1.3 s of main-thread work and 924 KiB of downloads while your page loads. That alone is enough to make taps feel slow. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

Cookie-Script.com costs a phone 1.3 s of main-thread work and 585 KiB of downloads while your page loads. That alone is enough to make taps feel slow. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

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

Your mobile performance score is 47. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

14 long tasks block the main thread while loading, the longest for 4.1 s. During a long task the page ignores taps.

8 third-party services load with your homepage (Cookie-Script.com, zuzana.ai and Google Tag Manager and others), adding 2.2 MB and 3.7 s of main-thread time.

Google Tag Manager costs a phone 912 ms of main-thread work and 498 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 597 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 300 ms faster on a phone.

5 files are served with short cache lifetimes, so returning visitors download them again (589 KiB).

About 24 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.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

Polyfills for old browsers add 42 KiB JavaScript that modern phones do not need.

1 image could be 8 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.

2 KiB could be saved by minifying JavaScript.

Visually, the page fills in at 16.4 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 5.7 s in total while the page loads. Good is under 200 ms.

The page becomes fully interactive after 26.1 s. Good is under 3.8 s.

Your largest element takes 4.1 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 262 ms to 1.5 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

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

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 2.6 s to 2.9 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

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 3.4 MB in 170 requests on a phone: scripts 2.3 MB (55), other files 750 KiB (92) and fonts 164 KiB (4). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.98 g of CO₂e: 117.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

Document should not have more than one contentinfo landmark: 1 element on the page fails this check, rated moderate by axe-core.

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 1 element on the page fails this check, rated moderate by axe-core.

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.

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

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

No meta description, so Google writes its own snippet from whatever text it finds.

There is no <h1>, so neither visitors nor Google get a clear main headline.

2 links have no real href, so search engines can't follow them.

Open Graph is missing og:description, so shared links fall back to guesses.

The homepage links to 58 pages on nexsmart.fr and 4 external pages.

A phone browser shows 39,163 words, but the HTML your server sends has only 1,295. GPTBot, ClaudeBot and PerplexityBot read that HTML without running JavaScript, so they see an almost empty page. Server-side rendering or pre-rendering fixes it.

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://nexsmart.fr/products/nexsmart-link-nvr-cameras-de-surveillance is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

https://nexsmart.fr/products/nexsmart%E2%84%A2-scope2-surveillance-camera-aon and https://nexsmart.fr/products/nexsmart%E2%84%A2-scope2-surveillance-camera all use the title “NEXSMART™ SCOPE2 – NEXSMART FR”. Search engines can't tell which page to show for a search, so each competes with the others.

https://nexsmart.fr/collections/black-month, https://nexsmart.fr/collections/solutions-en-package, https://nexsmart.fr/collections/maison-intelligente-securite-en-package and https://nexsmart.fr/collections/accessoires-de-camera have no meta description, so Google writes the search snippet from whatever text it finds.

https://nexsmart.fr/products/nexsmart%E2%84%A2-scope2-surveillance-camera-aon and https://nexsmart.fr/products/nexsmart%E2%84%A2-scope2-surveillance-camera use the same meta description. A description written for each page earns more clicks.

Your homepage links to 3 pages by a URL that isn't their canonical one, for example https://nexsmart.fr/products/nexsmart%E2%84%A2-scope2-surveillance-camera-aon, whose canonical is https://nexsmart.fr/products/nexsmart%e2%84%a2-scope2-surveillance-camera-aon. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

https://nexsmart.fr/collections/cameras-de-surveillance, https://nexsmart.fr/collections/solutions-en-package and https://nexsmart.fr/collections/maison-intelligente-securite took over 3 s to send their HTML from our server.

We fetched 15 pages linked from your homepage (of 34 found) and read each the way a search engine does.

20 of 25 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

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 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 39,163 words of visible text.

Before a visitor clicks anything, the page loads Google Tag Manager, Klaviyo and Meta Pixel (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 6 cookies, 2 of them by other companies (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 15 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
