lagencedecomm.fr website review

111 files are served with short cache lifetimes, so returning visitors download them again (2.5 MB).

28 files block the first paint until they finish downloading. Deferring or inlining them could save about 3.4 s.

About 615 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.5 s faster on a phone.

About 253 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 1.2 s faster on a phone.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 1.1 s).

5 images could be 595 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 450 ms faster on a phone.

Your mobile performance score is 51 (desktop: 63). 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 Didomi and others), adding 1.5 MB and 767 ms of main-thread time.

Google CDN costs a phone 309 ms of main-thread work and 734 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.

Google Tag Manager costs a phone 214 ms of main-thread work and 328 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.

A phone's processor spends 2.4 s on main-thread work while loading, 1.3 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Polyfills for old browsers add 32 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

10 long tasks block the main thread while loading, the longest for 166 ms. During a long task the page ignores taps.

19 KiB could be saved by minifying CSS.

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

5 KiB could be saved by minifying JavaScript.

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.

Your largest element takes 15.1 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “image evelyne et video”.

The page becomes fully interactive after 23.1 s. Good is under 3.8 s.

Visually, the page fills in at 7.6 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 3.8 s on a phone. Good is under 1.8 s.

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' tap response (inp) went from 94 ms to 120 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors see the first content after 1.9 s (75th percentile). Good is under 1.8 s.

Scripts block taps and scrolling for 281 ms in total while the page loads. Good is under 200 ms.

The layout shifts by 0.114 while loading, so content jumps under the reader's thumb. Good is under 0.1.

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

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' largest content (lcp) went from 2.1 s to 2.2 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 4.3 MB in 141 requests on a phone: scripts 2.0 MB (66), images 1.1 MB (13) and fonts 427 KiB (9). Under 2 MB keeps phones on slow connections fast.

papillon-480x480.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).

5 images (489 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.

1 image is downloaded at several times the size a phone draws it, for example slide-evelyne.jpg at 1,920 px wide, shown at 390 px. Resized copies would save about 53 KiB.

By the Sustainable Web Design model, a visit to your homepage emits about 1.21 g of CO₂e: 144.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Form elements should have a visible label: 1 element on the page fails this check, rated serious by axe-core.

All page content should be contained by landmarks: 17 elements on the page fail this check, rated moderate by axe-core.

Contentinfo 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 contentinfo 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 viewport tag blocks pinch-zoom, which low-vision visitors rely on.

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

1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.

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

ARIA role should be appropriate for the element: 1 element on the page fails this check, rated minor by axe-core.

Headings should not be empty: 1 element on the page fails this check, rated minor by axe-core.

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

The homepage links to 29 pages on lagencedecomm.fr and 14 external pages.

Your robots.txt shuts out ChatGPT (ChatGPT-User). These fetch pages to answer people's questions and cite the source, so your site can't be quoted or linked in those answers.

There is no https://www.evelyne.fr/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.

robots.txt blocks GPTBot, ClaudeBot and CCBot, which collect pages to train models. That's a legitimate choice and doesn't by itself stop the site appearing in AI answers.

https://www.evelyne.fr/nos-engagements has no meta description, so Google writes the search snippet from whatever text it finds.

https://www.evelyne.fr/news and https://www.evelyne.fr/la-ou-vous-etes have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 11 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: the server responded with a status of 404 ()”.

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.

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 421 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 (Didomi) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 6 cookies (measured from a US location before any click).

Loading the homepage contacts 16 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
