clearsmile.nl website review

6 third-party services load with your homepage (Shopify, Clarity and aov.ai and others), adding 89.2 MB and 225 ms of main-thread time.

Shopify costs a phone 141 ms of main-thread work and 89.1 MB 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.

Your mobile performance score is 88. Pages that score under 90 lose visitors before the first paint.

About 347 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 300 ms faster on a phone.

2 files block the first paint until they finish downloading. Deferring or inlining them could save about 450 ms.

About 30 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

2 long tasks block the main thread while loading, the longest for 78 ms. During a long task the page ignores taps.

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

27 KiB could be saved by minifying JavaScript.

4 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.

The page becomes fully interactive after 8.5 s. Good is under 3.8 s.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 142 ms to 181 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your largest element takes 3.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Wees de eerste met een stralende glimlach”.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 1.2 s to 1.2 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 90.3 MB in 165 requests on a phone: media 88.6 MB (3), other files 853 KiB (110) and scripts 688 KiB (43). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 25.60 g of CO₂e: 3072.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.

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

No meta description, so Google writes its own snippet from whatever text it finds.

Your title is only 10 characters: “Clearsmile”. Between 30 and 65 characters leaves room to say what you do and for whom.

No XML sitemap at https://clearsmile.nl/sitemap.xml, so Google discovers your pages only by following links.

The homepage links to only 0 pages on your own site, so visitors and crawlers find few routes into the rest of it.

Open Graph is missing og:title and og:description, so shared links fall back to guesses.

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://clearsmile.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.

6 errors were 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.

We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

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.

The homepage has only about 50 words of visible text; thin pages give Google and first-time buyers little to go on.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

Before a visitor clicks anything, the page loads Google Ads, Google Tag Manager, Meta Pixel, Microsoft Clarity and Snap 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.

Opening the homepage sets 22 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 23 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
