insidegroup.fr website review

22 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.4 s.

Your mobile performance score is 78. Pages that score under 90 lose visitors before the first paint.

6 third-party services load with your homepage (Google Tag Manager, LinkedIn Ads and Google/Doubleclick Ads and others), adding 555 KiB and 536 ms of main-thread time.

Google Tag Manager costs a phone 512 ms of main-thread work and 523 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.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 350 ms).

About 338 KiB of JavaScript is downloaded but never used on this page.

5 long tasks block the main thread while loading, the longest for 267 ms. During a long task the page ignores taps.

A phone's processor spends 2.4 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 2,278 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

About 27 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.

5 files are served with short cache lifetimes, so returning visitors download them again (25 KiB).

Polyfills for old browsers add 17 KiB JavaScript that modern phones do not need.

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.

Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

The page becomes fully interactive after 9.5 s. Good is under 3.8 s.

Real visitors see the first content after 2.2 s (75th percentile). Good is under 1.8 s.

Real visitors wait 1.8 s for your server to start answering (75th percentile). Good is under 800 ms.

Scripts block taps and scrolling for 495 ms in total while the page loads. Good is under 200 ms.

The layout shifts by 0.176 while loading, so content jumps under the reader's thumb. Good is under 0.1.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 2.5 s to 2.2 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 7.1 MB in 85 requests on a phone: media 5.9 MB (1), scripts 887 KiB (34) and fonts 226 KiB (3). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 2.02 g of CO₂e: 242.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Your title is 71 characters, so Google will cut it off around 60: “Inside : votre partenaire IT infrastructure, digital, IA, cybersec –ESN”.

The homepage links to 116 pages on insidegroup.fr and 3 external pages.

We fetched 15 pages linked from your homepage (of 86 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: net::ERR_FAILED”.

There is no /.well-known/security.txt telling researchers how to report a security problem to you.

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.

Social proof on the homepage: 1 trust badge. Pairing it with named testimonials or customer logos makes it far more convincing.

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.

DMARC is set to p=none, so mail pretending to be insidegroup.fr is still delivered. Add a report address, check the reports, then move to quarantine.

Email authentication: SPF record 25 points, plus 15 when it ends in -all (10 for ~all); DMARC record 25, plus 25 for a reject policy (15 for quarantine); a DKIM key on a common selector 10.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager and LinkedIn Insight (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 7 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 13 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
