squareconcepts.nl website review

Google Tag Manager costs a phone 343 ms of main-thread work and 503 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.

1 file blocks the first paint until they finish downloading. Deferring or inlining it could save about 300 ms.

5 third-party services load with your homepage (Google Tag Manager, cookiehub.eu and cookiehub.net and others), adding 558 KiB and 386 ms of main-thread time.

About 227 KiB of JavaScript is downloaded but never used on this page.

3 long tasks block the main thread while loading, the longest for 119 ms. During a long task the page ignores taps.

1 image could be 46 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

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

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.

The page becomes fully interactive after 7.0 s. Good is under 3.8 s.

Visually, the page fills in at 4.2 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 121 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

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.

By the Sustainable Web Design model, a visit to your homepage emits about 0.31 g of CO₂e: 37.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

<dl> elements must only directly contain properly-ordered <dt> and <dd> groups, <script>, <template> or <div> elements: 1 element on the page fails this check, rated serious by axe-core.

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.

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

ARIA role should be appropriate for the element: 1 element on the page fails this check, rated minor by axe-core.

The homepage links to 151 pages on squareconcepts.nl and 13 external pages.

We fetched 15 pages linked from your homepage (of 67 found) and read each the way a search engine does.

3 of 12 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

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 testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

The homepage shows no opening hours. If customers visit or call, show when.

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

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 1,535 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics and Google Tag Manager (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 1 cookie (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 5 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
