januswool.se website review

About 907 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.6 s faster on a phone.

A phone's processor spends 4.6 s on main-thread work while loading, 1.0 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 4,276 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Your mobile performance score is 51. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Google Tag Manager, Shopify and Klaviyo and others), adding 1.6 MB and 684 ms of main-thread time.

Google Tag Manager costs a phone 333 ms of main-thread work and 778 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 48 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.

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 300 ms.

Shopify costs a phone 193 ms of main-thread work and 470 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.

Polyfills for old browsers add 19 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

9 long tasks block the main thread while loading, the longest for 167 ms. During a long task the page ignores taps.

17 files are served with short cache lifetimes, so returning visitors download them again (55 KiB).

1 image could be 23 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

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.

2 KiB could be saved by minifying JavaScript.

Your largest element takes 8.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Janus-header-norse-fw-26_mobile.jpg”.

The page becomes fully interactive after 17.0 s. Good is under 3.8 s.

Visually, the page fills in at 9.6 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 409 ms in total while the page loads. Good is under 200 ms.

The layout shifts by 0.131 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.

Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

Your homepage downloads 6.1 MB in 399 requests on a phone: images 3.0 MB (76), scripts 1.7 MB (72) and other files 1.1 MB (222). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.73 g of CO₂e: 207.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

2 buttons have no accessible name, so screen readers announce just “button”.

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

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

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

All page content should be contained by landmarks: 4 elements on the page fail this check, rated moderate by axe-core.

Alternative text of images should not be repeated as text: 31 elements on the page fail this check, rated minor by axe-core.

Your meta description is only 68 characters: “Janus - naturally warm, high-quality merino wool produced in Norway.”. 70 to 160 characters is enough to sell the click.

Structured data found (Organization and WebSite) but with 1 problem, for example “Organization: url points at a different host (https://www.janus.no)”.

The homepage links to 470 pages on januswool.se and 2 external pages.

https://www.januswool.se/collections/ullklaer-til-dame, https://www.januswool.se/collections/classic-merino-160-women, https://www.januswool.se/collections/norse-merino, https://www.januswool.se/collections/classic-merino-women, https://www.januswool.se/collections/januspro and https://www.januswool.se/collections/best-selgere-til-dame took over 3 s to send their HTML from our server.

We fetched 15 pages linked from your homepage (of 114 found) and read each the way a search engine does.

30 of 75 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

The page uses 1 deprecated browser API that will stop working in future browsers (“Unload event listeners are deprecated and will be removed.”).

4 errors were logged to the browser console while the page loaded, for example “Could not find the payment icons ul”.

Chrome logged issues while loading the page (“Content security policy”).

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 2,609 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Klaviyo and Meta Pixel and 4 mores (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 20 cookies, 2 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 34 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
