Chrome UX Report (opens in a new tab): real Chrome visitors over rolling 28-day periods.
One score from every part of this review. How it works
Speed
Avoid multiple page redirects
6.2 sThe page goes through 1 redirect before it starts loading, costing about 6.2 s. Link and advertise the final URL directly.
Reduce unused JavaScript
1.4 s · 184 KiBAbout 184 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.4 s faster on a phone.
Mobile performance score: 48
48/100Your mobile performance score is 48 (desktop: 85). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.
Main-thread work: 4.7 s
A phone's processor spends 4.7 s on main-thread work while loading, 1.2 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.
Reduce unused CSS
424 KiBAbout 424 KiB of CSS is downloaded but never applied on this page.
Legacy JavaScript
300 ms · 46 KiBPolyfills for old browsers add 46 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 300 ms faster on a phone.
Render-blocking requests
300 ms2 files block the first paint until they finish downloading. Deferring or inlining them could save about 300 ms.
14 long tasks on the main thread
14 long tasks block the main thread while loading, the longest for 216 ms. During a long task the page ignores taps.
Phones get a much slower page than desktops
Desktop scores 85 but mobile only 48. A gap that wide usually means heavy scripts and images that hit phones hardest.
Chained critical requests
Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.
Forced reflow
Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

Cumulative Layout Shift: 0.018
0.018The layout barely moves while loading (CLS 0.018, good is under 0.1).
Images and page weight
Page weight: 12.6 MB in 165 requests
12.6 MBYour homepage downloads 12.6 MB in 165 requests on a phone: media 10.8 MB (6), HTML 779 KiB (2) and scripts 739 KiB (138). Under 2 MB keeps phones on slow connections fast.
About 3.6 g of CO₂ per visit
3.58 gBy the Sustainable Web Design model, a visit to your homepage emits about 3.58 g of CO₂e: 429.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.
3 checks passed
Images use modern formats
Every sizeable image is WebP, AVIF or SVG.
Images load when needed
Images below the first screen wait until the visitor scrolls to them.
Images are sized for phones
No image is downloaded at more than three times the size it is drawn on a phone.
Accessibility
6 text elements with low contrast
6 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 (12 elements)
All page content should be contained by landmarks: 12 elements on the page fail this check, rated moderate by axe-core.
Heading levels should only increase by one (1 element)
Heading levels should only increase by one: 1 element on the page fails this check, rated moderate by axe-core.
1 checks passed
41 automated accessibility rules passed
axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 44 WCAG 2.2 A/AA and best-practice rules on the phone render: 41 passed and 3 failed. 1 more need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.
SEO
No meta description
No meta description, so Google writes its own snippet from whatever text it finds.
No H1 headline
There is no <h1>, so neither visitors nor Google get a clear main headline.
No structured data
No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.
No canonical URL
No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.
No social preview image
No Open Graph image (also missing: og:title, og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.
Only 0 internal links
The homepage links to only 0 pages on your own site, so visitors and crawlers find few routes into the rest of it.
No favicon declared
No favicon is declared in the HTML, so browser tabs and Google's mobile results may show a generic icon.
3 links with vague text
3 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.
No X (Twitter) card tag
No twitter:card tag. X falls back to Open Graph, which is incomplete here.
3 checks passed
Title: 63 characters
Your title is a healthy 63 characters: “Omnilab - Full-Service, Laborbedarf, Chemikalien & Labortechnik”.
robots.txt in place
robots.txt is in place and points crawlers to your sitemap.
XML sitemap found
Your XML sitemap is reachable at https://www.omnilab.de/sitemap_index.xml.
AI search readiness
Most text only appears after JavaScript runs
0%A phone browser shows 559 words, but the HTML your server sends has only 0. 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.
No Organization structured data
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.
No llms.txt
There is no https://www.omnilab.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.
1 checks passed
AI answer engines may read the site
Your robots.txt lets the crawlers behind ChatGPT search, Claude and Perplexity read the site and cite it in answers.
Best practices
1 JavaScript error while loading
1 error was logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.
2 checks passed
Tap targets are thumb-sized
11 of 13 tappable elements near the top are at least 24 px.
Mobile viewport set
The page declares a mobile viewport.
Content and conversion
No call to action on the first screen
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 calls to action
We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.
No social proof
No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.
No analytics detected
No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.
No direct contact details
No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.
No form on the homepage
There is no form on the homepage, so every lead has to click through to another page first.
No risk reducer
No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.
About 559 words of copy
The homepage carries about 559 words of visible text.
Privacy and tracking
3 cookies set on arrival
3Opening the homepage sets 3 cookies, 1 of them by other companies (measured from a US location before any click).
No consent tool detected
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.
1 other company contacted
Loading the homepage contacts 1 host run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
1 checks passed
No known trackers before consent
No known advertising or analytics trackers load before a visitor clicks anything (measured from a US location before any click).
Security, domain, email and software versions
The security, domain and email checks, software and plugin versions, and any app with a known security problem are visible only to people at omnilab.de, because details like these could help someone attack a site. Every review keeps them private, whatever they found.
