power.no website review

About 825 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.8 s faster on a phone.

118 files are served with short cache lifetimes, so returning visitors download them again (912 KiB).

Your mobile performance score is 42 (desktop: 55). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 4.1 s on main-thread work while loading, 2.0 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

7 images could be 755 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

16 long tasks block the main thread while loading, the longest for 294 ms. During a long task the page ignores taps.

The page has 2,870 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

ZenDesk costs a phone 204 ms of main-thread work and 431 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 (ZenDesk, cloudfront.net and cookieinformation.com and others), adding 644 KiB and 435 ms of main-thread time.

About 125 KiB of CSS is downloaded but never applied on this page.

Polyfills for old browsers add 18 KiB JavaScript that modern phones do not need.

17 KiB could be saved by minifying CSS.

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

Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

Your largest element takes 13.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

The page becomes fully interactive after 23.5 s. Good is under 3.8 s.

Visually, the page fills in at 7.4 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 873 ms in total while the page loads. Good is under 200 ms.

The first text or image appears after 3.2 s on a phone. Good is under 1.8 s.

Real visitors wait 204 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

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

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 220 ms to 201 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 2.4 s to 2.5 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 4.0 MB in 181 requests on a phone: scripts 2.3 MB (121), images 1.1 MB (19) and fonts 278 KiB (6). Under 2 MB keeps phones on slow connections fast.

iphone_duo_buy_now_phase_affordability-768x768-web_mobile-no 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).

2 images are downloaded at several times the size a phone draws them, for example 4097683_8_1200x1200_t_g.webp at 1,200 px wide, shown at 322 px. Resized copies would save about 178 KiB.

By the Sustainable Web Design model, a visit to your homepage emits about 1.13 g of CO₂e: 135.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Images must have alternative text: 12 elements on the page fail this check, rated critical by axe-core.

Links must have discernible text: 12 elements on the page fail this check, rated serious by axe-core.

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

Heading levels should only increase by one: 1 element on the page fails this check, rated moderate by axe-core.

Page should contain a level-one heading: 1 element on the page fails this check, rated moderate by axe-core.

There is no <h1>, so neither visitors nor Google get a clear main headline.

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

No twitter:card tag. X falls back to Open Graph, which is set, so this is minor.

A phone browser shows 198 words, but the HTML your server sends has only 0. GPTBot, ClaudeBot and PerplexityBot read that HTML without running JavaScript, so they see an almost empty page. Server-side rendering or pre-rendering fixes it.

There is no https://www.power.no/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.

Large scripts ship without source maps.

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

There is no form on the homepage, so every lead has to click through to another page first.

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 Tag Manager and Microsoft Ads (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 9 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
