itk-engineering.de website review

About 276 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 1.2 s faster on a phone.

Your mobile performance score is 73. Pages that score under 90 lose visitors before the first paint.

1 file blocks the first paint until they finish downloading. Deferring or inlining it could save about 800 ms.

About 290 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 310 ms faster on a phone.

58 KiB could be saved by minifying CSS.

44 KiB could be saved by minifying JavaScript.

6 images could be 229 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 250 ms faster on a phone.

3 third-party services load with your homepage (Google Tag Manager, bosch.tech and svrdntfctn.com), adding 225 KiB and 134 ms of main-thread time.

27 files are served with short cache lifetimes, so returning visitors download them again (93 KiB).

2 long tasks block the main thread while loading, the longest for 62 ms. During a long task the page ignores taps.

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 4.7 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Zwei Ingenieur:innen präsentieren ihre vielseitige Expertis…”.

The page becomes fully interactive after 7.6 s. Good is under 3.8 s.

Visually, the page fills in at 5.9 s (Speed Index). Good is under 3.4 s.

Real visitors wait 1.3 s for your server to start answering (75th percentile). Good is under 800 ms.

The layout shifts by 0.136 while loading, so content jumps under the reader's thumb. Good is under 0.1.

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

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 93 ms to 110 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

4 images (357 KiB) are JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

By the Sustainable Web Design model, a visit to your homepage emits about 0.42 g of CO₂e: 50.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

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

The homepage links to 110 pages on itk-engineering.de and 4 external pages.

There is 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.

We fetched 15 pages linked from your homepage (of 67 found) and read each the way a search engine does.

Opening https://itk-engineering.de goes through 2 redirects before the homepage loads.

There is no /.well-known/security.txt telling researchers how to report a security problem to you.

itk-engineering.de has no CAA record, so any certificate authority may issue a certificate for it. A CAA record naming your provider (for example letsencrypt.org) closes that door.

Social proof on the homepage: 10 customer or partner logos. Pairing it with named testimonials or customer logos makes it far more convincing.

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 615 words of visible text.

Email authentication: SPF record 25 points, plus 15 when it ends in -all (10 for ~all); DMARC record 25, plus 25 for a reject policy (15 for quarantine); a DKIM key on a common selector 10.

Before a visitor clicks anything, the page loads 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 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 3 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
