supernerds.no website review

About 795 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 4.5 s faster on a phone.

15 files are served with short cache lifetimes, so returning visitors download them again (368 KiB).

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

Your mobile performance score is 44. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 5.8 s on main-thread work while loading, 3.3 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google Tag Manager, Shopify and Clarity and others), adding 2.6 MB and 1.6 s of main-thread time.

About 78 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 600 ms faster on a phone.

Google Tag Manager costs a phone 551 ms of main-thread work and 828 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.

Shopify costs a phone 283 ms of main-thread work and 817 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.

The page has 2,222 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

rebuyengine.com costs a phone 124 ms of main-thread work and 353 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.

11 images could be 212 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 200 ms faster on a phone.

17 long tasks block the main thread while loading, the longest for 189 ms. During a long task the page ignores taps.

26 KiB could be saved by minifying JavaScript.

Polyfills for old browsers add 39 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 50 ms faster on a phone.

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.

Your largest element takes 18.7 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Last inn video:”.

The page becomes fully interactive after 21.6 s. Good is under 3.8 s.

Visually, the page fills in at 9.4 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 681 ms in total while the page loads. Good is under 200 ms.

The first text or image appears after 3.1 s on a phone. Good is under 1.8 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 113 ms to 146 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

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

Your homepage downloads 8.9 MB in 502 requests on a phone: media 4.1 MB (2), scripts 2.5 MB (202) and other files 1.1 MB (213). Under 2 MB keeps phones on slow connections fast.

25647bc39f8d4cd99b655ddd53878c9e.thumbnail.0000000000.jpg is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

1 image (37 KiB) is 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.

2 images further down the page (78 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 2.53 g of CO₂e: 303.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

3 images have no alt text, which hurts accessibility and image search.

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

The homepage links to 78 pages on supernerds.no and 12 external pages.

https://supernerds.no/policies/shipping-policy has no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 15 pages linked from your homepage (of 45 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”.

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

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

Social proof on the homepage: 2 testimonial or review blocks. Pairing it with named testimonials or customer logos makes it far more convincing.

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 155 words of visible text; thin pages give Google and first-time buyers little to go on.

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.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Meta Pixel and Microsoft Clarity 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 28 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 30 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
