undz.com website review

Your mobile performance score is 71. Pages that score under 90 lose visitors before the first paint.

8 images could be 839 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

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

Shopify costs a phone 72 ms of main-thread work and 319 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.

About 149 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.

4 third-party services load with your homepage (Klaviyo, Shopify and shop.app and others), adding 510 KiB and 153 ms of main-thread time.

7 files are served with short cache lifetimes, so returning visitors download them again (39 KiB).

2 long tasks block the main thread while loading, the longest for 58 ms. During a long task the page ignores taps.

About 32 KiB of CSS is downloaded but never applied on this page.

Polyfills for old browsers add 19 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.

Your largest element takes 13.2 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 13.7 s. Good is under 3.8 s.

Visually, the page fills in at 4.3 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 2.0 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 70 ms to 72 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 3.9 MB in 231 requests on a phone: images 2.3 MB (20), other files 725 KiB (78) and scripts 589 KiB (96). Under 2 MB keeps phones on slow connections fast.

Sans_titre_b82826e5-08c0-4059-9a2a-3e9eec0e0a51.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).

By the Sustainable Web Design model, a visit to your homepage emits about 1.12 g of CO₂e: 133.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

3 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.

Summary elements must have discernible text: 1 element on the page fails this check, rated serious by axe-core.

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

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

Structured data found (Organization and WebSite) but with 1 problem, for example “Organization: logo is not an absolute URL ("https:files/undztag.png")”.

No favicon is declared in the HTML, so browser tabs and Google's mobile results may show a generic icon.

Your <h1> is empty.

The homepage links to 72 pages on undz.com and 9 external pages.

https://undz.ca/customer_authentication/redirect has no <title>, so Google invents the link text in results.

https://undz.ca/customer_authentication/redirect is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

https://undz.ca/collections/men-homme, https://undz.ca/collections/bamboo-men-2025, https://undz.ca/collections/classic-boxer-brief-boxer-classique, https://undz.ca/collections/swim-trunks, https://undz.ca/collections/women-femme and https://undz.ca/collections/sport-bra-soutien-gorge-sport and 9 others have no meta description, so Google writes the search snippet from whatever text it finds.

https://undz.ca/customer_authentication/redirect has no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 26 found) 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 ()”.

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.

The homepage has only about 118 words of visible text; thin pages give Google and first-time buyers little to go on.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, 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 14 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 16 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
