tonair.fr website review

About 757 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 4.7 s faster on a phone.

20 files are served with short cache lifetimes, so returning visitors download them again (565 KiB).

Google Tag Manager costs a phone 1.1 s of main-thread work and 1,000 KiB 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.

Your mobile performance score is 48. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 4.1 s on main-thread work while loading, 2.0 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google Tag Manager, Facebook and hs-sites-eu1.com and others), adding 2.0 MB and 1.6 s of main-thread time.

10 files block the first paint until they finish downloading. Deferring or inlining them could save about 500 ms.

About 29 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.

hs-sites-eu1.com costs a phone 141 ms of main-thread work and 450 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.

17 long tasks block the main thread while loading, the longest for 239 ms. During a long task the page ignores taps.

2 images could be 28 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Polyfills for old browsers add 13 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.

Your largest element takes 18.8 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 20.2 s. Good is under 3.8 s.

Scripts block taps and scrolling for 1.2 s in total while the page loads. Good is under 200 ms.

Real visitors wait 3.2 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors wait 203 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Visually, the page fills in at 4.9 s (Speed Index). Good is under 3.4 s.

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

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 162 ms to 169 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 2.3 s to 2.3 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 3.3 MB in 193 requests on a phone: scripts 1.9 MB (66), other files 697 KiB (83) and images 331 KiB (14). Under 2 MB keeps phones on slow connections fast.

Plan_de_travail_114_4c33ce36-e115-48a4-9e01-411597e62f6c.jpg 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 0.92 g of CO₂e: 110.8 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: 22 elements on the page fail this check, rated moderate by axe-core.

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

Headings skip levels (h1 → h3), which makes the page harder to scan with a screen reader.

Elements with visible text labels do not have matching accessible names. (1 element).

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

There are 2 <h1> headlines (“.logo_image { max-height: unset!important; width:…” and “.logo_image { max-height: unset!important; width:…”). One clear main headline is easier for people and search engines.

Your meta description is 178 characters; Google truncates after about 160, so the end of your pitch is cut.

1 link has no real href, so search engines can't follow it.

No twitter:card tag. X falls back to Open Graph, which is set, so this is minor.

The homepage links to 55 pages on tonair.fr and 5 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.

https://www.tonair.fr/collections/catalogue-tonair, https://www.tonair.fr/collections/module-wifi, https://www.tonair.fr/collections/accessoires-1, https://www.tonair.fr/collections/accessoires-installation, https://www.tonair.fr/collections/accessoires-entretiens and https://www.tonair.fr/collections/all and 2 others have no meta description, so Google writes the search snippet from whatever text it finds.

https://www.tonair.fr/pages/promoteurs-immobilier, https://www.tonair.fr/pages/artisans-frigoristes-installateurs and https://www.tonair.fr/pages/contact have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 17 found) and read each the way a search engine does.

7 of 19 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

1 third-party cookie is set on load; browsers are restricting these, so whatever relies on them breaks.

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 ()”.

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

Social proof on the homepage: 5 testimonial or review blocks. Pairing it with named testimonials or customer logos makes it far more convincing.

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 443 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, HubSpot and Meta Pixel (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 24 cookies, 8 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 32 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
