sievers-group.com website review

2 files block the first paint until they finish downloading. Deferring or inlining them could save about 750 ms.

The page has 2,320 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

nitrocdn.com costs a phone 32 ms of main-thread work and 404 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.

14 files are served with short cache lifetimes, so returning visitors download them again (96 KiB).

1 image could be 15 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.

3 long tasks block the main thread while loading, the longest for 76 ms. During a long task the page ignores taps.

1 third-party service load with your homepage (nitrocdn.com), adding 404 KiB and 32 ms of main-thread time.

About 67 KiB of CSS is downloaded but never applied on this page.

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 3.3 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Ihr Partner für IT und Digital Business. Wir bringen dem Mi…”.

Visually, the page fills in at 3.6 s (Speed Index). Good is under 3.4 s.

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

By the Sustainable Web Design model, a visit to your homepage emits about 0.36 g of CO₂e: 42.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

1 form field has no label, so screen readers announce an empty box and autofill guesses.

Structured data found (BreadcrumbList, Organization, SiteNavigationElement and WebPage) but with 2 problems, for example “BreadcrumbList: itemListElement is an empty list”.

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

The homepage links to 360 pages on sievers-group.com and 10 external pages.

There is no https://www.sievers-group.com/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://www.sievers-group.com/solution and https://www.sievers-group.com/solution/business-intelligence/datenmanagement/schnelle-datenanalysen-mit-datenbankloesungen-von-exasol have no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 15 pages linked from your homepage (of 122 found) and read each the way a search engine does.

3 of 13 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

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.

Social proof on the homepage: 4 trust badges. Pairing it with named testimonials or customer logos makes it far more convincing.

Your longest form asks for 8 fields (4 required). Every extra field lowers completion.

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 610 words of visible text.

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