teufel.de website review

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

The page has 8,195 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

About 436 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 600 ms faster on a phone.

Your mobile performance score is 70. Pages that score under 90 lose visitors before the first paint.

About 142 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 450 ms faster on a phone.

11 files are served with short cache lifetimes, so returning visitors download them again (154 KiB).

A phone's processor spends 2.3 s on main-thread work while loading, 785 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

teufelaudio.com costs a phone 0 ms of main-thread work and 592 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.

3 third-party services load with your homepage (Kameleoon, Tealium and teufelaudio.com), adding 634 KiB and 99 ms of main-thread time.

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

Polyfills for old browsers add 13 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.

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 7.0 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Mit Cookies verarbeiten wir und andere Marketingpartner Dat…”.

The page becomes fully interactive after 10.4 s. Good is under 3.8 s.

Real visitors wait 203 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 179 ms to 268 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

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

Visually, the page fills in at 5.2 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 2.3 s to 2.2 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.0 MB in 233 requests on a phone: scripts 645 KiB (29), images 593 KiB (189) and fonts 306 KiB (4). 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: 68.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Certain ARIA roles must be contained by particular parents: 3 elements on the page fail this check, rated critical by axe-core.

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

1 element has a tabindex above 0, which scrambles the keyboard order.

1 image has no alt text, which hurts accessibility and image search.

All page content should be contained by landmarks: 11 elements on the page fail this check, rated moderate by axe-core.

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 2 elements on the page fail this check, rated moderate by axe-core.

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

Headings skip levels (h1 → h4), which makes the page harder to scan with a screen reader.

No meta description, so Google writes its own snippet from whatever text it finds.

20 links have no real href, so search engines can't follow them.

Structured data found (Organization and WebSite) but with 1 problem, for example “WebSite: missing name”.

No XML sitemap at https://teufel.de/sitemap.xml, so Google discovers your pages only by following links.

4 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

Open Graph is missing og:description, so shared links fall back to guesses.

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

The homepage links to 163 pages on teufel.de and 65 external pages.

There is no https://teufel.de/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.

https://teufel.de/agb, https://teufel.de/support, https://teufel.de/b2b, https://teufel.de/shops, https://teufel.de/black-friday and https://teufel.de/stereo and 7 others have no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 15 pages linked from your homepage (of 77 found) and read each the way a search engine does.

1 error was logged to the browser console while the page loaded, for example “cloudinary-video failed to be defined Failed to execute 'define' on 'CustomElementRegistry': the name "cloudinary-video…”.

8 images are displayed at the wrong aspect ratio, so they look stretched or squashed.

1 image is served at too low a resolution for sharp phone screens.

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.

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.

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 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 1,787 words of visible text.

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

Opening the homepage sets 14 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 3 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
