leistritz.com website review

25 files are served with short cache lifetimes, so returning visitors download them again (628 KiB).

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.5 s.

About 321 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.6 s faster on a phone.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 1.3 s).

Your mobile performance score is 56 (desktop: 78). Pages that score under 90 lose visitors before the first paint.

9 images could be 587 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 300 ms faster on a phone.

3 third-party services load with your homepage (Google Maps, Cookie-Script.com and LinkedIn Ads), adding 452 KiB and 510 ms of main-thread time.

About 59 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 300 ms faster on a phone.

6 long tasks block the main thread while loading, the longest for 299 ms. During a long task the page ignores taps.

Google Maps costs a phone 252 ms of main-thread work and 384 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.

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.

Polyfills for old browsers add 4 KiB JavaScript that modern phones do not need.

Your largest element takes 8.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

The page becomes fully interactive after 14.2 s. Good is under 3.8 s.

Visually, the page fills in at 7.6 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 3.3 s on a phone. Good is under 1.8 s.

Scripts block taps and scrolling for 279 ms in total while the page loads. Good is under 200 ms.

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

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' tap response (inp) went from 103 ms to 112 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' largest content (lcp) went from 1.2 s to 1.2 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 3.4 MB in 36 requests on a phone: images 2.1 MB (19), scripts 627 KiB (6) and fonts 591 KiB (6). Under 2 MB keeps phones on slow connections fast.

9 images further down the page (434 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 0.96 g of CO₂e: 115.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

All page content should be contained by landmarks: 7 elements on the page fail this check, rated moderate by axe-core.

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

Headings skip levels (h1 → h3), 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 structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

No XML sitemap at https://www.leistritz.com/sitemap.xml, so Google discovers your pages only by following links.

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

1 link has no real href, so search engines can't follow it.

The homepage links to 78 pages on leistritz.com and 32 external pages.

A phone browser shows 2,905 words, but the HTML your server sends has only 630. GPTBot, ClaudeBot and PerplexityBot read that HTML without running JavaScript, so they see an almost empty page. Server-side rendering or pre-rendering fixes it.

There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

There is no https://www.leistritz.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.leistritz.com/en/start, https://www.leistritz.com/de/start, https://www.leistritz.com/it/start and https://www.leistritz.com/es/start all use the title “Innovation Engineering | Leistritz - Leistritz AG”. Search engines can't tell which page to show for a search, so each competes with the others.

https://www.leistritz.com/en/contact, https://www.leistritz.com/en/company/human-rights, https://www.leistritz.com/en/company/compliance and https://www.leistritz.com/en/company/ombudsman have no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 15 pages linked from your homepage (of 34 found) and read each the way a search engine does.

1 image failed to load on a phone, for example https://www.leistritz.com/en/start.

25 of 32 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

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.

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

There is no form on the homepage, so every lead has to click through to another page first.

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 2,905 words of visible text.

Before a visitor clicks anything, the page loads LinkedIn Insight (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 4 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 4 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
