superstellar.nl website review

The page has 4,234 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

2 files block the first paint until they finish downloading. Deferring or inlining them could save about 900 ms.

4 long tasks block the main thread while loading, the longest for 603 ms. During a long task the page ignores taps.

A phone's processor spends 3.6 s on main-thread work while loading, 1.0 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

LoyaltyLion costs a phone 69 ms of main-thread work and 352 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.

8 third-party services load with your homepage (Shopify, LoyaltyLion and JSDelivr CDN and others), adding 636 KiB and 295 ms of main-thread time.

12 images could be 156 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

About 130 KiB of JavaScript is downloaded but never used on this page.

16 files are served with short cache lifetimes, so returning visitors download them again (44 KiB).

About 37 KiB of CSS is downloaded but never applied on this page.

7 KiB could be saved by minifying JavaScript.

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 10.1 s. Good is under 3.8 s.

Scripts block taps and scrolling for 346 ms in total while the page loads. Good is under 200 ms.

Visually, the page fills in at 3.6 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 112 ms to 145 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.

Your homepage downloads 3.6 MB in 309 requests on a phone: images 2.2 MB (167), scripts 769 KiB (100) and fonts 444 KiB (5). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.02 g of CO₂e: 122.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Scrollable region must have keyboard access: 11 elements on the page fail this check, rated serious by axe-core.

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

Documents must have <title> element to aid in navigation: 1 element on the page fails this check, rated serious by axe-core.

<html> element must have a lang attribute: 1 element on the page fails this check, rated serious by axe-core.

1 image has no alt text, which hurts accessibility and image search.

All page content should be contained by landmarks: 8 elements on the page fail this check, rated moderate 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.

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

Alternative text of images should not be repeated as text: 19 elements on the page fail this check, rated minor by axe-core.

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

The <html> element has no lang attribute, so screen readers may read the page in the wrong voice and accent.

Headings should not be empty: 1 element on the page fails this check, rated minor by axe-core.

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

Your page has no <title>, so Google has to invent the blue link in search results.

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

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

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 404 pages on superstellar.nl and 0 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.

https://superstellar.us/collections/baby-girls, https://superstellar.us/collections/baby-one-pieces, https://superstellar.us/collections/baby-pants and https://superstellar.us/collections/diaper-bags took over 3 s to send their HTML from our server.

We fetched 15 pages linked from your homepage (of 146 found) and read each the way a search engine does.

16 of 77 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

4 errors were logged to the browser console while the page loaded, for example “window.klaviyo.init is not a function”.

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.

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 385 words of visible text.

Before a visitor clicks anything, the page loads Klaviyo (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 10 cookies, 1 of them by other companies (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 20 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
