supplend.com website review

About 484 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.1 s faster on a phone.

23 files are served with short cache lifetimes, so returning visitors download them again (344 KiB).

4 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.4 s.

8 third-party services load with your homepage (Clarity, Google Tag Manager and TikTok and others), adding 7.2 MB and 906 ms of main-thread time.

Your mobile performance score is 59. Pages that score under 90 lose visitors before the first paint.

Shopify costs a phone 131 ms of main-thread work and 6.1 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.

Polyfills for old browsers add 69 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 300 ms faster on a phone.

A phone's processor spends 3.6 s on main-thread work while loading, 1.9 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

7 long tasks block the main thread while loading, the longest for 169 ms. During a long task the page ignores taps.

2 images could be 16 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 50 ms faster on a phone.

About 11 KiB of CSS is downloaded but never applied on this page.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Your largest element takes 13.4 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “De Supplend Nagelverzorgingspen in beeld”.

The page becomes fully interactive after 16.5 s. Good is under 3.8 s.

The first text or image appears after 4.1 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 6.2 s (Speed Index). Good is under 3.4 s.

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

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 162 ms to 160 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 8.4 MB in 271 requests on a phone: media 5.7 MB (1), scripts 1.5 MB (93) and other files 1.0 MB (156). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 2.39 g of CO₂e: 287.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

All page content should be contained by landmarks: 57 elements on the page fail this check, rated moderate by axe-core.

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

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

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

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

The homepage links to 16 pages on supplend.com and 0 external pages.

We fetched 2 pages linked from your homepage 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.

A local customer looking to call finds no phone number on the homepage. Add one, ideally as a tap-to-call link.

Your longest form asks for 9 fields (3 required). Every extra field lowers completion.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

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 1,731 words of visible text.

Opening the homepage sets 26 cookies, 1 of them by other companies (measured from a US location before any click).
