neurowaste.com website review

About 641 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 4.7 s faster on a phone.

8 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.5 s.

Your mobile performance score is 50. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Google CDN, Google Tag Manager and website-files.com and others), adding 1.8 MB and 626 ms of main-thread time.

About 51 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.

Google CDN costs a phone 264 ms of main-thread work and 750 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.

13 images could be 255 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Google Tag Manager costs a phone 216 ms of main-thread work and 339 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.

website-files.com costs a phone 84 ms of main-thread work and 600 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.

4 KiB could be saved by minifying CSS.

4 long tasks block the main thread while loading, the longest for 152 ms. During a long task the page ignores taps.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Your largest element takes 19.5 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Find true power in your data with 455nm”.

The first text or image appears after 7.2 s on a phone. Good is under 1.8 s.

The page becomes fully interactive after 19.7 s. Good is under 3.8 s.

Visually, the page fills in at 7.2 s (Speed Index). Good is under 3.4 s.

The layout shifts by 0.144 while loading, so content jumps under the reader's thumb. Good is under 0.1.

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

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 46 requests on a phone: other files 1.4 MB (8), scripts 1.1 MB (12) and images 518 KiB (17). Under 2 MB keeps phones on slow connections fast.

646788ddf672d8ce2c1bdd3c_planning_tournee_collecte_dechets-p 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).

1 image (58 KiB) is JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

By the Sustainable Web Design model, a visit to your homepage emits about 0.98 g of CO₂e: 117.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Links must have discernible text: 1 element on the page fails this check, rated serious by axe-core.

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

1 form field has no label, so screen readers announce an empty box and autofill guesses.

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

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

Your meta description is 704 characters; Google truncates after about 160, so the end of your pitch is cut.

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

There is no robots.txt at neurowaste.com/robots.txt, the first file search crawlers ask for.

The homepage links to 10 pages on neurowaste.com and 2 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.neurowaste.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.

https://www.neurowaste.com/mentionslegales and https://www.neurowaste.com/politiqueconfidentialite are marked noindex but linked from your homepage. If they are meant to be found, remove the noindex.

https://www.neurowaste.com/mentionslegales and https://www.neurowaste.com/politiqueconfidentialite have no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 3 pages linked from your homepage and read each the way a search engine does.

2 errors were logged to the browser console while the page loaded, for example “%c%d font-size:0;color:transparent NaN”.

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 phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

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 927 words of visible text.

Before a visitor clicks anything, the page loads Google Ads 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 2 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 12 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
