sterr24.de website review

Your mobile performance score is 78. Pages that score under 90 lose visitors before the first paint.

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 600 ms.

About 49 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 150 ms faster on a phone.

1 long task block the main thread while loading, the longest for 50 ms. During a long task the page ignores taps.

3 third-party services load with your homepage (Shopify, Judge.me and shop.app), adding 75 KiB and 21 ms of main-thread time.

About 26 KiB of CSS is downloaded but never applied on this page.

1 image could be 16 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

3 files are served with short cache lifetimes, so returning visitors download them again (5 KiB).

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

Your largest element takes 6.0 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 6.0 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 84 ms to 88 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 2.0 s to 1.9 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.0 MB in 186 requests on a phone: other files 1.1 MB (129), images 465 KiB (16) and scripts 265 KiB (34). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.57 g of CO₂e: 68.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 element use ARIA attributes their role does not allow, which confuses screen readers.

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

5 elements hidden from screen readers can still receive keyboard focus.

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

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.

Your meta description is 206 characters; Google truncates after about 160, so the end of your pitch is cut.

The homepage links to 126 pages on sterr24.de and 1 external page.

Your Organization JSON-LD is missing url, logo, sameAs (social profiles) and description. 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 53 found) and read each the way a search engine does.

17 of 67 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

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 403 ()”.

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

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

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

The homepage shows no opening hours. If customers visit or call, show when.

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.

The homepage carries about 357 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics and Google Tag Manager (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 12 cookies (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 12 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
