sustainsoft.eu website review

Your mobile performance score is 84. Pages that score under 90 lose visitors before the first paint.

4 files block the first paint until they finish downloading. Deferring or inlining them could save about 900 ms.

5 images could be 182 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 700 ms faster on a phone.

8 third-party services load with your homepage (Google Tag Manager, Clarity and website-files.com and others), adding 1.3 MB and 542 ms of main-thread time.

Google Tag Manager costs a phone 293 ms of main-thread work and 497 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.

The page has 1,811 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

website-files.com costs a phone 55 ms of main-thread work and 570 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 234 KiB of JavaScript is downloaded but never used on this page.

5 long tasks block the main thread while loading, the longest for 116 ms. During a long task the page ignores taps.

20 files are served with short cache lifetimes, so returning visitors download them again (18 KiB).

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.

The page becomes fully interactive after 9.9 s. Good is under 3.8 s.

Your largest element takes 4.3 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

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

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.

1 image is downloaded at several times the size a phone draws it, for example 691cadedb3658e24e266306e_Group 1000002758 (1).webp at 1,526 px wide, shown at 351 px. Resized copies would save about 85 KiB.

By the Sustainable Web Design model, a visit to your homepage emits about 0.41 g of CO₂e: 49.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Banner landmark should not be contained in another landmark: 1 element on the page fails this check, rated moderate by axe-core.

Document should not have more than one banner 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 homepage links to 81 pages on sustainsoft.eu and 6 external pages.

There is no https://www.sustainsoft.eu/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.sustainsoft.eu/fr/simulateur-ecovadis is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

https://www.sustainsoft.eu/fr/a-propos and https://www.sustainsoft.eu/a-propos all use the title “À Propos de SustainSoft | Leader SaaS ESG - Équipe & Mission Durabili…”. Search engines can't tell which page to show for a search, so each competes with the others.

https://www.sustainsoft.eu/fr/a-propos and https://www.sustainsoft.eu/a-propos use the same meta description. A description written for each page earns more clicks.

Your homepage links to 1 page by a URL that isn't its canonical one, for example https://www.sustainsoft.eu/a-propos, whose canonical is https://www.sustainsoft.eu/fr/a-propos. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

https://www.sustainsoft.eu/fr/simulateur-ecovadis and https://www.sustainsoft.eu/fr/blog have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 24 found) and read each the way a search engine does.

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

There is no form on the homepage, so every lead has to click through to another page first.

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 607 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager and Microsoft Clarity (measured from a US location before any click). A consent tool (CookieYes) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 2 cookies (measured from a US location before any click).

Loading the homepage contacts 18 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
