jolyn.dk website review

About 527 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.8 s faster on a phone.

10 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.3 s.

Your mobile performance score is 36. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 6.3 s on main-thread work while loading, 4.6 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google Tag Manager, Klaviyo and Clarity and others), adding 1.4 MB and 1.2 s of main-thread time.

Google Tag Manager costs a phone 626 ms of main-thread work and 670 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 85 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 450 ms faster on a phone.

19 files are served with short cache lifetimes, so returning visitors download them again (125 KiB).

19 long tasks block the main thread while loading, the longest for 351 ms. During a long task the page ignores taps.

Klaviyo costs a phone 173 ms of main-thread work and 346 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.

The page has 1,844 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Polyfills for old browsers add 46 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 200 ms faster on a phone.

41 KiB could be saved by minifying JavaScript.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

3 images could be 45 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.

Your largest element takes 13.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Training Costumes & Swim Bikini | Chlorine Resistant Swimwe…”.

The page becomes fully interactive after 18.7 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.

Visually, the page fills in at 7.5 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 3.5 s on a phone. Good is under 1.8 s.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 153 ms to 183 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

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

Your homepage downloads 3.1 MB in 262 requests on a phone: scripts 1.6 MB (93), other files 903 KiB (133) and images 292 KiB (15). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.89 g of CO₂e: 106.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Certain ARIA roles must be contained by particular parents: 1 element on the page fails this check, rated critical by axe-core.

ARIA attributes must conform to valid names: 1 element on the page fails this check, rated critical by axe-core.

5 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.

Interactive controls must not be nested: 1 element on the page fails this check, rated serious by axe-core.

All page content should be contained by landmarks: 2 elements on the page fail this check, rated moderate by axe-core.

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

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

Headings skip levels (h2 → h4), which makes the page harder to scan with a screen reader.

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

Your title is 84 characters, so Google will cut it off around 60: “Training Costumes & Swim Bikini | Chlorine Resistant Swimwear | JOLYN – Jolyn Europe”.

Your meta description is 162 characters; Google truncates after about 160, so the end of your pitch is cut.

The homepage links to 119 pages on jolyn.dk and 4 external pages.

Your Organization JSON-LD is missing logo, description and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

https://eu.jolynclothing.com/collections/brolyn and https://eu.jolynclothing.com/collections/limited-edition-contrast-training-costumes use the same meta description. A description written for each page earns more clicks.

We fetched 15 pages linked from your homepage (of 73 found) and read each the way a search engine does.

4 errors were logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

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 454 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Klaviyo and Meta Pixel and 1 more (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.

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 38 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
