allbirds.fr website review

Shopify costs a phone 1.1 s of main-thread work and 530 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.

The page has 4,012 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

A phone's processor spends 4.0 s on main-thread work while loading, 2.2 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

6 third-party services load with your homepage (Shopify, ZenDesk and JSDelivr CDN and others), adding 1.1 MB and 1.4 s of main-thread time.

6 images could be 313 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 850 ms faster on a phone.

Your mobile performance score is 63. Pages that score under 90 lose visitors before the first paint.

About 330 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 150 ms faster on a phone.

7 files block the first paint until they finish downloading. Deferring or inlining them could save about 350 ms.

12 long tasks block the main thread while loading, the longest for 256 ms. During a long task the page ignores taps.

ZenDesk costs a phone 211 ms of main-thread work and 431 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.

7 files are served with short cache lifetimes, so returning visitors download them again (17 KiB).

About 59 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.

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 5.7 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 11.1 s. Good is under 3.8 s.

Real visitors wait 271 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Scripts block taps and scrolling for 548 ms in total while the page loads. Good is under 200 ms.

Visually, the page fills in at 4.0 s (Speed Index). Good is under 3.4 s.

Your homepage downloads 3.1 MB in 182 requests on a phone: images 1.0 MB (19), scripts 899 KiB (77) and other files 862 KiB (65). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.87 g of CO₂e: 103.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

9 elements hidden from screen readers can still receive keyboard focus.

5 tap targets are too small or too close together to hit reliably with a finger.

16 images have no alt text, which hurts accessibility and image search.

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.

Page should contain a level-one heading: 1 element on the page fails this check, rated moderate by axe-core.

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

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

There is no <h1>, so neither visitors nor Google get a clear main headline.

Structured data found (BreadcrumbList, Organization and WebSite) but with 1 problem, for example “Organization: url points at a different host (https://allbirds.de)”.

The homepage links to 179 pages on allbirds.fr and 17 external pages.

https://allbirds.fr/pages/black-friday-pre-sale is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

https://allbirds.fr/collections/slides-fur-herren, https://allbirds.fr/collections/terralux-herren and https://allbirds.fr/collections/varsity-fur-herren have no meta description, so Google writes the search snippet from whatever text it finds.

Your homepage links to 1 page by a URL that isn't its canonical one, for example https://allbirds.fr/collections/semelles-amovibles/Herren, whose canonical is https://allbirds.fr/collections/semelles-amovibles/herren. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

https://allbirds.fr/collections/hommes, https://allbirds.fr/collections/sneakers-hommes, https://allbirds.fr/collections/slides-fur-herren, https://allbirds.fr/collections/wasserdichte-schuhe-herren, https://allbirds.fr/collections/semelles-amovibles/Herren and https://allbirds.fr/collections/tree-runner-nz-hommes and 8 others have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 88 found) and read each the way a search engine does.

15 of 25 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: the server responded with a status of 404 ()”.

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

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 434 words of visible text.

Before a visitor clicks anything, the page loads Klaviyo 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 11 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.
