tarnnetz.com website review

A phone's processor spends 5.3 s on main-thread work while loading, 775 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 3,817 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

16 images could be 936 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 150 ms faster on a phone.

Your mobile performance score is 77. Pages that score under 90 lose visitors before the first paint.

About 295 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 300 ms faster on a phone.

2 files block the first paint until they finish downloading. Deferring or inlining them could save about 450 ms.

8 third-party services load with your homepage (loox.io, Klaviyo and Klarna and others), adding 734 KiB and 369 ms of main-thread time.

About 38 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.

3 long tasks block the main thread while loading, the longest for 77 ms. During a long task the page ignores taps.

9 files are served with short cache lifetimes, so returning visitors download them again (58 KiB).

Polyfills for old browsers add 19 KiB JavaScript that modern phones do not need.

12 KiB could be saved by minifying JavaScript.

11 KiB JavaScript is shipped twice across bundles.

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 5.6 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 11.3 s. Good is under 3.8 s.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 141 ms to 177 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 1.3 s to 1.3 s 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 8.1 MB in 236 requests on a phone: media 3.9 MB (1), images 2.4 MB (48) and other files 798 KiB (104). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 2.31 g of CO₂e: 277.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Delayed refresh under 20 hours must not be used: 1 element on the page fails this check, rated critical by axe-core.

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

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

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

4 tap targets are too small or too close together to hit reliably with a finger.

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

Headings skip levels (h2 → h4), which makes the page harder to scan with a screen reader.

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

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

The homepage links to 218 pages on tarnnetz.com and 0 external pages.

Your Organization JSON-LD is missing logo, sameAs (social profiles), 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.

We fetched 15 pages linked from your homepage (of 58 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: the server responded with a status of 429 ()”.

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

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

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

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 2 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
