numericable.fr website review

28 files are served with short cache lifetimes, so returning visitors download them again (459 KiB).

2 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.1 s.

Your mobile performance score is 85. Pages that score under 90 lose visitors before the first paint.

About 179 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 470 ms faster on a phone.

s-sfr.fr costs a phone 122 ms of main-thread work and 622 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.

2 third-party services load with your homepage (s-sfr.fr and Google Tag Manager), adding 623 KiB and 123 ms of main-thread time.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 150 ms).

5 images could be 98 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

1 long task block the main thread while loading, the longest for 92 ms. During a long task the page ignores taps.

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

Your largest element takes 3.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

The page becomes fully interactive after 4.9 s. Good is under 3.8 s.

The first text or image appears after 2.1 s on a phone. Good is under 1.8 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 209 ms to 221 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 1.4 s to 1.4 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Banner_logo-numericable_mobile.webp 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).

By the Sustainable Web Design model, a visit to your homepage emits about 0.22 g of CO₂e: 26.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

All page content should be contained by landmarks: 6 elements on the page fail this check, rated moderate by axe-core.

Heading levels should only increase by one: 1 element on the page fails this check, rated moderate by axe-core.

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

No meta description, so Google writes its own snippet from whatever text it finds.

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

The homepage links to 145 pages on numericable.fr and 42 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.sfr.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.

Your homepage links to https://www.sfr.fr/mon-espace-client, https://www.sfr.fr/offre-internet/options and https://www.sfr.fr/options/repeteur-wifi7, which answer with an error. Visitors hit a dead end and search engines drop them.

We fetched 15 pages linked from your homepage (of 99 found) and read each the way a search engine does.

4 of 12 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_HTTP2_PROTOCOL_ERROR”.

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 analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

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 556 words of visible text.

Before a visitor clicks anything, the page loads 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 2 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 2 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
