ducadelcosma.nl website review

Your mobile performance score is 78. Pages that score under 90 lose visitors before the first paint.

12 files block the first paint until they finish downloading. Deferring or inlining them could save about 950 ms.

About 470 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.

8 third-party services load with your homepage (Google Tag Manager, Klaviyo and Trust Pilot and others), adding 1.1 MB and 433 ms of main-thread time.

17 files are served with short cache lifetimes, so returning visitors download them again (441 KiB).

Google Tag Manager costs a phone 189 ms of main-thread work and 377 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 1,823 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Klaviyo costs a phone 125 ms of main-thread work and 354 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.

5 images could be 53 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 150 ms faster on a phone.

3 long tasks block the main thread while loading, the longest for 109 ms. During a long task the page ignores taps.

Polyfills for old browsers add 19 KiB JavaScript that modern phones do not need.

8 KiB JavaScript is shipped twice across bundles.

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.

3 KiB could be saved by minifying JavaScript.

The page becomes fully interactive after 11.8 s. Good is under 3.8 s.

Your largest element takes 5.0 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

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

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 128 ms to 144 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.9 MB in 276 requests on a phone: scripts 1.4 MB (90), other files 803 KiB (108) and images 461 KiB (34). Under 2 MB keeps phones on slow connections fast.

week3-wblock-men_1500x1500_095ff159-bcd5-4217-a371-6184caad4 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 0.82 g of CO₂e: 98.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

9 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.

1 image has 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.

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

3 form fields have no label, so screen readers announce an empty box and autofill guesses.

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

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

There are 2 <h1> headlines (“” and “”). One clear main headline is easier for people and search engines.

The homepage links to 118 pages on ducadelcosma.nl and 8 external pages.

https://ducadelcosma.com/nl-nl/collections/sale-dames-golfschoenen, https://ducadelcosma.com/nl-nl/collections/sale-heren-golfschoenen, https://ducadelcosma.com/nl-nl/collections/heren-golfschoenen and https://ducadelcosma.com/nl-nl/collections/dames-golfschoenen have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 49 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: net::ERR_TUNNEL_CONNECTION_FAILED”.

Large scripts ship without source maps.

Social proof on the homepage: 22 trust badges. Pairing it with named testimonials or customer logos makes it far more convincing.

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 354 words of visible text.

Before a visitor clicks anything, the page loads Google Analytics, Google Tag Manager, Klaviyo, Meta Pixel and Microsoft Ads (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 16 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 26 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
