prospection-digitale.com website review

About 1.6 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 9.1 s faster on a phone.

hsappstatic.net costs a phone 1.5 s of main-thread work and 3.0 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.

About 100 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 1.1 s faster on a phone.

Your mobile performance score is 31. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 5.3 s on main-thread work while loading, 2.7 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (hsappstatic.net, Google Tag Manager and Hubspot and others), adding 4.1 MB and 2.2 s of main-thread time.

44 files are served with short cache lifetimes, so returning visitors download them again (1.0 MB).

15 files block the first paint until they finish downloading. Deferring or inlining them could save about 650 ms.

Google Tag Manager costs a phone 520 ms of main-thread work and 722 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 323 ms. During a long task the page ignores taps.

Hubspot costs a phone 146 ms of main-thread work and 352 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 50 ms).

3 images could be 21 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

7 KiB JavaScript is shipped twice across bundles.

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 15.3 s on a phone. Good is under 1.8 s.

Your largest element takes 15.3 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Vous voulez générer plus de chiffre d'affaires mais vous êt…”.

The page becomes fully interactive after 27.7 s. Good is under 3.8 s.

Visually, the page fills in at 15.3 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 1.3 s in total while the page loads. Good is under 200 ms.

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 9.8 MB in 148 requests on a phone: media 5.1 MB (2), scripts 3.6 MB (75) and fonts 492 KiB (15). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 2.77 g of CO₂e: 332.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Certain ARIA roles must contain particular children: 1 element on the page fails this check, rated critical by axe-core.

Some list items are not inside a list.

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

Your title is 67 characters, so Google will cut it off around 60: “Jubyl | Excellence digitale | Prospection, vente, expérience client”.

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

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

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

The homepage links to 15 pages on prospection-digitale.com and 0 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.jubyl.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.jubyl.com/contact and https://www.jubyl.com/contact-experts have 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 6 pages linked from your homepage 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”.

Large scripts ship without source maps.

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.

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 1,307 words of visible text.

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

Opening the homepage sets 17 cookies, 8 of them by other companies (measured from a US location before any click).

Loading the homepage contacts 20 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
