zenozorg.nl website review

10 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.8 s.

59 files are served with short cache lifetimes, so returning visitors download them again (2.1 MB).

Your mobile performance score is 75 (desktop: 89). Pages that score under 90 lose visitors before the first paint.

About 59 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 750 ms faster on a phone.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 750 ms).

14 images could be 333 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.

A phone's processor spends 2.8 s on main-thread work while loading, 689 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

5 third-party services load with your homepage (JSDelivr CDN, Clarity and Cloudflare CDN and others), adding 188 KiB and 386 ms of main-thread time.

About 63 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.

1 long task block the main thread while loading, the longest for 53 ms. During a long task the page ignores taps.

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 13.9 s. Good is under 3.8 s.

The first text or image appears after 3.6 s on a phone. Good is under 1.8 s.

Your largest element takes 4.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Recruitee imported image”. Most of its time is resource load delay (1.8 s).

Visually, the page fills in at 5.1 s (Speed Index). Good is under 3.4 s.

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 2.3 MB in 81 requests on a phone: fonts 1.3 MB (9), images 619 KiB (41) and scripts 199 KiB (13). Under 2 MB keeps phones on slow connections fast.

2 images (79 KiB) are JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

1 image further down the page (30 KiB) download before anyone scrolls to it. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 0.64 g of CO₂e: 77.4 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”.

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

1 form field has no label, so screen readers announce an empty box and autofill guesses.

Headings skip levels (h1 → h3, h3 → h5 and h2 → h5), which makes the page harder to scan with a screen reader.

Your meta description is only 37 characters: “Zeno. Strategisch partner in de zorg.”. 70 to 160 characters is enough to sell the click.

The homepage links to 76 pages on zenozorg.nl and 115 external pages.

There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

There is no https://zenozorg.nl/llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.

https://zenozorg.nl/aanmelden-als-zorgprofessionals, https://zenozorg.nl/zorgorganisaties, https://zenozorg.nl/dienst/zeno-ambulant, https://zenozorg.nl/zorgprofessionals, https://zenozorg.nl/onze-diensten and https://zenozorg.nl/dienst/zeno-consultancy and 9 others use the same meta description. A description written for each page earns more clicks.

We fetched 15 pages linked from your homepage (of 31 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_FAILED”.

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

Your homepage shows a map but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

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

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 417 words of visible text.

Before a visitor clicks anything, the page loads Microsoft Clarity (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 10 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
