matters.tech website review

About 4.9 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 4.0 s faster on a phone.

YouTube costs a phone 2.8 s of main-thread work and 7.8 MB 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.

7 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.8 s.

A phone's processor spends 10.0 s on main-thread work while loading, 5.9 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Your mobile performance score is 35 (desktop: 54). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

8 third-party services load with your homepage (YouTube, Embedly and cloudfront.net and others), adding 13.1 MB and 4.7 s of main-thread time.

30 images could be 2.2 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 750 ms faster on a phone.

Embedly costs a phone 766 ms of main-thread work and 1.4 MB 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.

cloudfront.net costs a phone 519 ms of main-thread work and 31 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 163 ms of main-thread work and 3.2 MB 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 171 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 Tag Manager costs a phone 326 ms of main-thread work and 340 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.

20 long tasks block the main thread while loading, the longest for 314 ms. During a long task the page ignores taps.

9 KiB could be saved by minifying CSS.

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

9 files are served with short cache lifetimes, so returning visitors download them again (6 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 first text or image appears after 8.2 s on a phone. Good is under 1.8 s.

Your largest element takes 10.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Studio Produit, Tech & IA”.

The page becomes fully interactive after 60.0 s. Good is under 3.8 s.

Visually, the page fills in at 8.2 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 967 ms in total while the page loads. Good is under 200 ms.

35 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 13.8 MB in 263 requests on a phone: scripts 7.5 MB (80), images 3.1 MB (45) and HTML 2.1 MB (62). Under 2 MB keeps phones on slow connections fast.

6851637964c32d7e35340fcc_planet_1-p-500.png 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 is downloaded at several times the size a phone draws it, for example 638df9fe97a47d39203e1f46_Logo_Matters.svg at 1,354 px wide, shown at 100 px. Resized copies would save about 110 KiB.

2 images (73 KiB) are 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 3.90 g of CO₂e: 467.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

All page content should be contained by landmarks: 15 elements on the page fail this check, rated moderate by axe-core.

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

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

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

Headings skip levels (h1 → h3 and h1 → 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.

There are 11 <h1> headlines (“Studio Produit, Tech & IA”, “Ce que nous faisons” and “Nos success stories”). One clear main headline is easier for people and search engines.

The homepage links to 35 pages on matters.tech and 4 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://matters.tech/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://matters.tech/services/du-prototype-au-minimum-viable-product-mvp, https://matters.tech/services/faire-evoluer-votre-produit-pour-quil-apporte-plus-de-valeur, https://matters.tech/services/accelerer-vos-intitiatives-dinnovation-, https://matters.tech/services/un-coup-de-boost-cible-pour-vos-equipes-produit-tech, https://matters.tech/services/service-finops-pilotage-et-optimisation-cloud and https://matters.tech/services/audit-tech-ux-et-due-diligence and 1 other all use the title “Matters Startup & Product studio”. Search engines can't tell which page to show for a search, so each competes with the others.

https://matters.tech/services/du-prototype-au-minimum-viable-product-mvp, https://matters.tech/services/faire-evoluer-votre-produit-pour-quil-apporte-plus-de-valeur, https://matters.tech/services/accelerer-vos-intitiatives-dinnovation-, https://matters.tech/services/un-coup-de-boost-cible-pour-vos-equipes-produit-tech, https://matters.tech/services/service-finops-pilotage-et-optimisation-cloud and https://matters.tech/services/audit-tech-ux-et-due-diligence and 1 other have no meta description, so Google writes the search snippet from whatever text it finds.

https://matters.tech/nous-contacter has under 150 words in the HTML. Thin pages rarely rank; if the text loads with JavaScript, crawlers that don't run it see even less.

We fetched 15 pages linked from your homepage (of 21 found) and read each the way a search engine does.

5 third-party cookies are set on load; browsers are restricting these, so whatever relies on them breaks.

1 image is served at too low a resolution for sharp phone screens.

Chrome logged issues while loading the page (“Cookie”).

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 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 722 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics 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 5 cookies, 1 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 22 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
