the3dexpert.com website review

9 images could be 368 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 1.2 s faster on a phone.

About 513 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.1 s faster on a phone.

12 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.5 s.

A phone's processor spends 5.9 s on main-thread work while loading, 2.5 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 5,882 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Your mobile performance score is 58. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Klaviyo, boostcommerce.io and Shopify and others), adding 1.0 MB and 659 ms of main-thread time.

Klaviyo costs a phone 173 ms of main-thread work and 366 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.

About 48 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.

13 long tasks block the main thread while loading, the longest for 141 ms. During a long task the page ignores taps.

11 files are served with short cache lifetimes, so returning visitors download them again (49 KiB).

Polyfills for old browsers add 49 KiB JavaScript that modern phones do not need.

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.

3 KiB could be saved by minifying JavaScript.

2 KiB could be saved by minifying CSS.

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.

For real visitors the layout shifts by 0.59 (75th percentile). Good is under 0.1.

Your largest element takes 12.2 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 18.8 s. Good is under 3.8 s.

Visually, the page fills in at 6.6 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 2.6 s on a phone. Good is under 1.8 s.

Scripts block taps and scrolling for 316 ms in total while the page loads. Good is under 200 ms.

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 147 ms to 153 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 2.2 s to 2.1 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 4.2 MB in 315 requests on a phone: scripts 1.6 MB (117), images 1.3 MB (29) and other files 933 KiB (124). Under 2 MB keeps phones on slow connections fast.

Braendende_Black_Week-tilbud.png 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).

By the Sustainable Web Design model, a visit to your homepage emits about 1.19 g of CO₂e: 142.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 button has no accessible name, so screen readers announce just “button”.

Form elements should have a visible label: 3 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.

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

All page content should be contained by landmarks: 21 elements on the page fail this check, rated moderate by axe-core.

Document should not have more than one banner landmark: 1 element on the page fails 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.

The viewport tag blocks pinch-zoom, which low-vision visitors rely on.

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

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

Headings skip levels (h1 → h3), which makes the page harder to scan with a screen reader.

Your <h1> is empty.

The homepage links to 701 pages on the3dexpert.com and 6 external pages.

Your Organization JSON-LD is missing logo, description and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

https://3deksperten.dk/pages/kontakt-os, https://3deksperten.dk/collections/istandsat-3d-printere, https://3deksperten.dk/collections/maskiner and https://3deksperten.dk/collections/akryl-bukkemaskine have no meta description, so Google writes the search snippet from whatever text it finds.

https://3deksperten.dk/collections/black-week-alle-tilbud-samlet, https://3deksperten.dk/pages/handelsbetingelser-1, https://3deksperten.dk/pages/kontakt-os, https://3deksperten.dk/collections/3d-printere, https://3deksperten.dk/collections/fdm and https://3deksperten.dk/collections/resin-printer and 9 others have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 198 found) and read each the way a search engine does.

1 error was logged to the browser console while the page loaded, for example “Cannot set properties of undefined (setting 'status')”.

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 analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

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 1,793 words of visible text.

The page uses urgency cues (a countdown or limited-time wording).

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Klaviyo and Meta Pixel and 2 mores (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 24 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 45 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
